           Proceedings

Welcome: Mayor Lynne Woolstencroft

           The Mayor offered a warm welcome to the participants on behalf of the City of Waterloo.
           Waterloo is a leader in environmental initiatives starting with the environment first policy the
           City has implemented since the early 1990’s and more recently with the Environmental
           Strategic Plan. Waterloo was fortunate to receive of two of Federation of Canadian
           Municipalities Green Municipal Enabling Funds for both a Solar Power Pilot project and
           Green Roof Feasibility Study.

           The City of Waterloo is in the midst of implementing a green roof research and demonstration
           project designed to better understand the nature of public benefits associated with widespread
           green roof implementation. Green roofs, if widely implemented, can provide multiple
           environmental, economic, and social benefits to our community while helping building
           owners reduce energy consumption and extend the life of their roofing systems.

           Mayor Woolstencroft mentioned that the workshop would provide an opportunity for
           participants to learn from local and national experts about the design and implementation of
           green roofs with session on Plants and Landscaping as well as Design and Waterproofing.
           As well this was an opportunity for workshop participants to help shape the Waterloo Green
           roof feasibility study by providing input in the afternoon focus sessions.

Purpose & Objectives: Karen Moyer, City of Waterloo, Environmental Coordinator

           The culture of Waterloo looks towards the future, to investigate new technologies like green
           roofs, to make Waterloo a better place to live. This is a philosophy that staff strives to carry
           out in daily operations, it is also what the Citizens of Waterloo want based on the feed back
           from the           Waterloo process. Through the              process the Environment was
           selected as top indicator of quality of life. The Environmental Strategic Plan lays out actions
           and phasing to improve the environment in Waterloo. Green roofs fall under the phase 2
           actions as areas that require more study prior to implementation.

           The formation of the Waterloo Green Roof Steering committee, which is a multi- disciplinary
           group of 12 professionals, as a key component in shaping the direction of the feasibility study.
           A summary of the key points of the Waterloo Green Roof Terms of Reference was provided
           and an overview of the role of the consultants was also provided. The purpose of the
           workshop was 3 fold: 1) Learn, 2) Network & 3) Develop. The participation in afternoon
           sessions would help to shape the Green Roof Waterloo Plan. With key topics such as Urban
           Agriculture, Stormwater Management, Air Quality and Smart Growth being the focus. The
           workshop also provided the opportunity to launch new partnerships and research potentials.


Introduction to Green Roofs – Benefits, Research Needs & Market Development :
Steven Peck, Executive Director, Green Roofs for Healthy Cities Coalition

           It is estimated that 30-50% of construction, operation and demolition of building's goes to the
           landfill site. We need to consider our buildings as “mini planets” that generate energy, clean
           the air and provide a healthy indoor environment. Green roofs are an infrastructure that is
           primitive, what’s old is new again. Plants on top of a human made structure that is above or
           below grade and can be used on a slope up to 40%.

           Extensive green roof systems have less than 6 inches of growing medium, and are low
           maintenance. Intensive green roof systems are accessible, usually require irrigation, have
           greater plant diversity and higher maintenance requirements. The components of a green roof
           system were shown (can be seen on website: www.greenroofs.ca). The various types of
           products were highlighted. Then examples of both Intensive & Extensive systems were
           shown. The main design features in an intensive system are: higher maintenance, heavier
           weight and structural load capacity, deeper soil based growing medium (20-60 cm), more
           plant varieties (trees & shrubs), often accessible to public or occupants of building, higher
           investment. Extensive system design features are: lower maintenance, light weight (12lbs/sf),
           shallow growing medium (5-15 cm), less plant variety (i.e. grasses, sedum’s, wildflowers),
           harsher conditions, less investment ($5 – 10 sq. ft), up to 40 degrees in slope.

           In Germany 980,000,000 sq. ft of roofs are green, so why aren’t we doing more in North
           America? Drivers for implementing green roofs are site specific; it depends on needs and
           concerns (i.e. air quality, hydrology issues). Also there are development pressures, such as
           Waterloo’s Uptown redevelopment, therefore the benefits are different for each community.
           There is an opportunity of public and private partnerships and co-benefits.

                                                                                                              5
              There is a multitude of public benefits from green roofs including the opportunity to build
              buildings with nature in mind for mental and physical well being. There are some challenges
              we must face to get green roofs implemented in North America, lots of research is being done
              on the benefits, most of them are for the general public, but one of the biggest questions from
              the private sector is “what’s in it for me?” Along with research on benefits, monitoring is also
              a key component for understanding green roof technology.

              Some of the cost benefits of green roof systems for Toronto were released in October of 2002.
              The findings were based on research from Environment Canada, National Research Council;
              Green Roofs for Healthy Cities, University of Toronto, City of Toronto and literature reviews:

-    6.5 million square meters = 6% roof area/1% of total land area
-    $45.5 million/year public and private investment over 10 years
-    1, 350 person years of employment
-    1-2 degree centigrade UHI Reduction
-    2.18 mega tones/year GHG emission reductions
-    5-10 % reduction in SMOG incidence
-    2.6 million cubic metres in stormwater or $60 million tank
-    30 tones in particulate matter
-    over $ 1 million in energy savings/year (this is difficult to quantify)
-    4.7 million kg of food from 10% of roofs
-    $ 4 – 5.5 million in value of organic produce
-    650,000 square metres of recreational space

              In closing, it is important to research local case for public incentives to leverage private
              investment in green roofs. We need to consider what are the key challenges & opportunities
              associated with developing a green roof industry in Waterloo.


Design & Waterproofing of Green Roofs : Zen Szewczyk, IRC Building Sciences
Group Inc.

What is a green roof? Where are they located? Below or at grade, it is an extension of a roof system. What
does it consist of? Extension of existing roof, drainage system, does not include potted plants. So of the
types of green roof systems are modular (drainage layer & filter) or a component system which is installed
in separate layers. The appeal of green roofs is for stormwater management, cooling of roofs, aesthetics,
energy conservation and overall benefit to the community. Some of the design considerations for green
roofs are:

a)   Type of planting system:
-    intensive: more elaborate design, pedestrian access, specifically engineered, depth of over 6 inches,
     diverse plants, begins at 50lbs/sq/ft.
-    extensive: lower weight, lower costs, minimal maintenance, medium (not soil), depth of 2 – 6 inches,
     13 – 18 lbs./sq./ft when dry, low maintenance vegetation, left alone after it is established.

b) System selection Criteria: determine structural capacity of structure & cost implications
c) Source of Water: determine source of water, needs to be available to get plants established, prevents
   cause for fire hazard in dry conditions, good irrigation for introduction of fertilizers
d) Source of electricity: lighting, irrigation system control
e) Roof Access: to allow maintenance & viewing of area

                                                                                                             6
f)   Safety: especially when talking about top of roof structure, hand railing & clear pathways for walking
g)   Long-term serviceability: built in leak detection system so you can isolate the problem
h)   Maintenance: landscaping, weeding etc.
i)   Eventual replacement: even though green roofs last along time they will need to be replaced
     (especially the membrane system)
j)   Budgeting – need to consider upgrading, maintenance costs (design & type of system will vary cost)

What does it cost?
Conventional roof: $7-15/sq ft
Protected membrane: $8-18/sq ft
Green roof - $20 –50/sq ft

Most buildings built in the last 25 years would need some additional support for an intensive green roof
system, new structures can build this into the design.

How do you convince the client that a green roof is something they should invest in? The public sector
takes this on more easily with the numerous public benefits. Data available discusses the environmental
payback etc., it is really a dollars and cents issue


Plants and Landscaping of Green roofs : Kaaren Pearce, Elevated Landscape
Technology

 Trees contain a root ball, maintain structure. Design considerations from the construction perspective are
 the load restrictions, this is very important on retrofits. Some of the reasons for greening roofs are
 different from private vs. public from the funding required and the needs e.g.) hospital – increased
 healing; school – education perspective, home owner – aesthetics/environmental awareness

 Extensive:
 - low soil depth 3-5 inches
 - low weight – average 27-40 lbs./ sq. ft
 - watering
 - alpine species (handle little water & little soil) – low water capacity and minimum wind effects
 - non accessible
 - habitat for: insects, plants, seed banks, birds & butterflies, education, reduction in urban heat island
 - wildflower seed mix – most have lupines which will break through root barrier, biennial mixes will
 have flowers the 1st year and dormant the second.
 - Sod roofs – will require maintenance, removal of tree seedlings – unless designed for this
 - Tundra – lichens & mosses

 Intensive:
 -   trees & shrubs
 -   people access
 -   great for hospitals (down time for staff & people visiting, burn patients, therapy)

 Semi-intensive:
 -   design areas of heavier loading vs. lighter
 -   work with structural engineer for locating loads & design

                                                                                                              7
Plants:
- plants will do their best to stay alive even though they need a deep soil depth to reach their full
potential
- bush clover is great for honey production
- culitvars – bred so that they have a specific feature
- alpine phlox – not done well – likely a cultivar
- chives – excellent (1inch of soil or less)
- sedum – good spreader, native ones available 1/4inch of soil & little water, they are succulent so they
catch the water & hang on to it
- dog tooth violet – does great
- thyme’s
- grasses
- alpine's – lots are short-lived

Stormwater management use different types of plants all together
- want a mixture of plants, perennials, biennials, wind tolerant plants

Some of the hidden costs are irrigation, maintenance, shipping materials etc



Case study 1: Sears Merchandise Condominium Building: Terry McGlade,
Horticulturist, President, Perennial Gardens Corporation


Water retention areas:
- not a simple solution for green roofs – all are individual
- “catch basin” type of containers, original goal to collect the runoff, they decided to put marsh species
in them, like marsh marigold, joe pye weed, astilbles, waterloving plants
- inverted roof, 4 inch Styrofoam, tar, pea-gravel, drains on top* need access to drains
- need to retain your medium e.g.: decorative slabs
- planted groupings in waves for changes over the seasons
- certain plants can be planted at certain sizes:
-       sedum used plugs – can use any type for these species (2 inch deep (size of loonie))
-       water before you plant since putting in layers & don’t want soil to blow away – water every day
for 2-3 weeks


Lessons:
1) do not use plugs – they cannot grow roots fast enough to take hold
2) 4 inch pot issues – if planting at certain time of year i.e. July – root mass too developed: need to
separate soil from roots – therefore it takes time


Maintenance:
- trees seed easily (i.e. poplars seeding in this location from a mile away)
- constant problem to remove seedlings
- need perennials to knit together to form a root mass to keep other plants out
- watering – Kaaren Pearce discovered that when stopped watering (after the plants are established) the
weeds went away & natives/other flourished

    - * native plants are best
    - plant closer together e.g.) plant together at 6 inch spacing rather than at the 1 foot, however it does
    increase costs since you need more plants



Case Study 2: Grand River Hospital Horticultural Therapy Green Roof: Richard
Dixon & Fred Vermeulen

                Vision: We comfort, assess, restore and educate to support the health of our patients
                and community

                Mission: In partnership with you, we will champion excellent health care services in
                pursuit of a healthy community.

Green roofs & Horticultural & Hospitals:

•        Allow people with physical and mental illness to experience the restorative properties of nature

•        Physical environment plays an important role in every individuals sense of well being and can have a
         positive influence on behaviour and good health

•        Interaction with nature can reduce physiological manifestations of anxiety

•        Hospital patients encountering nature have shorter hospital stays, use less medication and have a
         more positive recovery course (Ulrich 1979)

•        Staff are more productive, patients have more tolerance for medical procedures, families less
         stressed (Marcus and Barnes 1995)

•        Patients having interaction with nature and horticulture therapy can increase cognitive functioning
         (Kaplan 1973)

•        Therapeutic environments incorporate outdoor space into the design of the total environment of
         healing (Stevens 1996)

•        Creativity in developing roof gardens is rather inexpensive compared to the outcome of doing
         nothing

Design Elements:
•        Create an inviting and pleasant atmosphere for all: patients, visitors, staff, physicians, volunteers
•        Create landscape opportunities adjacent to high acuity programs
•        Provide a positive image for the hospital
•        Provide plantings that offer seasonal change and interest

                                                                                                                 9
Natural Elements: Fragrance, touch, hearing and seeing are all part of the experience.

       •      Air: A gentle breeze
       •      Water: A country stream
       •      Sunshine: Warm daylight
       •      Vegetation: Growth of life
       •      Fragrance: Smell of roses
       •      Touch: The feel of earth
       •      Hearing: Sound of birds
       •      Seeing: The beauty of landscapes

Key points for Construction: Need to have excellent contractors to do the job that can look at all the
elements. Construction of hospital buildings is complicated: need qualified contractors to do the work well.
Roofing systems must marry to landscaping technologies; membranes which tolerate the growing media
and resultant plant roots, earth pressures, etc Overall strategy to allow roofing membranes to last longer;
less cost as membranes are protected. Green roofs will save operating costs in heating and cooling. Size of
HVAC units can be reduced; engineers are currently resistant to this reduction without proven track record.
Positive response to Kyoto Accord; reduce energy use, reduce urban heat island effect, provide oxygen,
reduce CO2


Green roofs at the Hospital:
Three roof areas adjacent Renal Dialysis on one side and Childbirth and Children’s on the other side, over
top of the new Emergency. The radiation treatment rooms at the Grand River Regional Cancer Centre have
skylights, perennials will be planted on the roof adjacent to this, it is not for use actively but passively used
by offices. The Kaufman courtyard provides new opportunities for patients to visit the garden before and
after treatment for chemotherapy, radiation therapy as well as a quiet place for visitors, staff, physicians,


volunteers and family.

Technology Tip: to find leaks use a detection system – International Leak Detection (ILD) provides
Electric Field Vector Mapping (EFVM). EFVM consists of a wire rectangular loop on the roof; every 3 sec.
a 40-volt pulse is generated for a period of 1 sec. An electrical potential difference is set up between the
(wet) roof surface and the roof deck. If there is a leak, then a small electrical current will flow down
through the puncture. A receiver can then identify the exact location of the leak. For further information
contact: Chris Eichhorn, International Leak Detection; chris@leak-detection.com

To wrap things up Richard provided the following points about green roofs & why we should do them:

Think outside of the bun,            Creativity costs very little,         People appreciate the effort,
It helps the environment,            Unusual access to the outdoors,       It benefits people,

Case Study 3: YMCA Paradise Lake : Charles Simon, Architect + Planner

             Preamble

             Suggestion that we might expand the concept of “green roof” to include some more
             economical strategies which still meet some of the objectives:

A) Vertical green: grow plants up sides of buildings (air cleansing, building cooling…). Also
              referred to in CMHC report. Could include edible landscape (eg. grapes, espalier).

B) Overhead canopy: Trellises, canopies, etc. (light weight, cools building and people,
            air cleansing).

C) Light green: some plants in planters, containers, limited areas (eg. over structural columns) and
              possible combinations of the above. Could include limited food production (eg. herbs,
              grapes).

             Above would get people using roof spaces while assisting many of the environmental goals,
             eg. reductions in energy use, emissions, provision of recreation space, limited food
             production, improving visual quality of cities and towns.

             Even with more standard definitions of green roofs (referring to Steven Peck’s presentation),
             Charles made suggestion that there are more economical options than those offered by the
             commercial systems. However, these systems are excellent, reliable and take a lot of liability
             from the designer. So ‘custom’ designs require good building science and plant knowledge,
             require more front-end professional time and may be more risky. Nevertheless, all our
             projects to date have fallen into this category (fiscal imperatives).

             Environmental Learning Centre

             77 acre site outside Waterloo on Paradise Lake, near St. Clements.

             Objective: the whole site, including its buildings, materials, technologies & landscape
             design, to embody the most comprehensive and ambitious physical embodiment of
             sustainable principles known to the client and its consultants. To gently encourage lifestyle
             changes through education programs and the experience of the Centre’s environment.

             2 buildings incorporate green roofs: Earth Residence (sleeping up to 40 pp., off-grid), fully
                                                 earth sheltered on north side with earth carried on over the

                                                 roof above the sleeping areas.

                                                : Day Centre (main assembly & office space), incorporating
                                                  a ‘Living Machine’ - biological sewage treatment system -

                                                 in a large greenhouse which also passively heats & cools

                                                  the building.

             3rd. set of off-grid straw bale cabins in construction & partially in use.

             Both sets green roofs on slopes of up to 1:3. Experimentation with clayey soils and no
             intermediate blocking to prevent slippage (& thereby protect EPDM roof membrane). Soil of
             Earth Residence joined to soil at grade at foot of slope.

             Results:
             Generally very successful. Some slippage occurred at outset on 1:3 slopes of Earth Residence,
             topped up a few times & subsequently stabilized after roots had become established. Lower
             slopes of Day Centre experienced no problems. Soil on both buildings had been temporarily
             stabilized by organic (straw based) matting which composted within a year.
             Client further experimented by using clayey soil on roofs steeper than 1:3 (cost saving
             measure). As feared, soil slid off & due to frost also damaged roof membrane. Intention is to
             return to original proposal to use mineral wool (from ‘Roxul’) as growth medium. A further
             experiment, but based on fact that this insulation material was originally developed for
             hydroponic greenhouse production.



Keynote speaker : Wayne Roberts - Quick Starts


             10 quick start points:

1) Establish public policy
2) Need outside assistance
3) Capacity to be high consensus issue
4) Cost savings
5) Beneficiaries in several domains of life:
-  economy
-  environmentally – diversity, food production (unsustainable – our food travels over 1500 miles to get
   to us)
- urban heat island effect – health benefit
- cultural benefit (places you feel comfortable in i.e.: randomness and border)
- creative class
6) Multiple beneficiaries
- innovative roofers
- hospitals
- water works departments
- tax payers – major asset – don’t have to pay entire cost – benefits are free to the public

7) Ready to go: don’t need to set up and money is available to get started, etc.
8) Champion government: task forces across departments, money does grow on trees! Over 100 benefits
    they provide, conflict between economy & environment.
    Most of our business and bureaucracy are built on a vertical scale and our environment is a horizontal
    scale. That is why there is a conflict between the two: horizontal benefits & vertical growth.
9) Non government partner to implement
10) Power of one: inner peace, positive attitude, sense of being

The Status of Green Roof Research in North America: Experiences learned abroad
and locally: Nada Sutic, University of Waterloo and Ryan Kennedy, Public Health,
Regional Municipality of Waterloo

Nada & Ryan provided an intensive review of green roof research in North America. They offered some
discussion of the challenges facing researchers, such as the fact that a lot of the work is based on urban
forestry data, which may or may not be directly transferable. Issues were raised around modeling, how
useful it is the fact that many people are skeptical about the benefits, especially when discussing the urban
heat island effect. Also in relation to the Urban Heat Island, there are no real base lines in areas where
there are many green roofs (such as Germany), and that widespread implementation of green roofs is
difficult to achieve, making it difficult to obtain real Urban Heat Island data on green roofs.


Storm Water Management:
-   retain significant portion of rainfall, detain runoff, water quality
    - Portland, Oregon – Hamilton Apartments
    - Monitoring equipment
    - West and east sides – different growing medium – only 35% runoff from rain fall event
    - Increasing depth of growing medium makes significant difference in amount of runoff (>depth =
         lower runoff)
    Examples:
-   National Research Council in Ottawa shows good examples to base similar climate comparisons –
    divided roof monitoring conventional roof vs. green roof
-   Penn State University
    - 6 small buildings
-   Winnipeg
-   Vancouver – reducing volume of runoff roof creates from lots with varying lot coverage


Energy Efficiency
-   extra layer of insulation to reduce cooling costs (heating cost minimal)
-   shading of roof membrane (in summer on regular roof high temp fluctuations - less on green roof)
-   Information provided by Karen Lu at NRC
-   Heat gain in summer almost non existent
-   Heat flow through surface of roof
             Examples:
-   In Waterloo our Feasibility study will be looking at modeling the energy efficiency of different green
    roof systems
-   Eastview Community Centre – Toronto


Urban Heat Island Effect:
-   dark roof’s are like hot plates
-   can be up to 10% higher in temperature in core versus rural settings
-   Why is this important?
    - Heat related deaths: heat + poor air quality ( especially O3 particulate matter)
    - Increased use of electricity (air conditioning)

        -     Peak demands met by nuclear energy and hydro vs. use of coal most times powered by
              electricity
              Role of Green roofs:
-   surface area of some plants to take up pollutants
-   NRC, Environment Canada modeling of impacts of green roofs in Toronto using remote sensing –
    reference???
-   Plants filter air contaminates, provide surface area for reactive chemicals like ozone also act as a
    carbon sink


Food production
-   reduced transportation of food & emissions associated with transport
-   food grown where people can consume it
             Examples:
-   Fairmont Royal York, Toronto – Herb Garden
-   Fairmont Waterfront Hotel Garden, Vancouver – herb garden

              Policy, Initiatives & Incentives:
-   Portland – density bonus for every 1 sq. ft of green roof, get 1-3 sq. ft bonus of floor area & property
    owners can get 35% off Stormwater charges
-   Seattle – New City funded projects and renovations of over 5000 ft2 must have silver rating in USGBC
    LEED rating system™.
-   Chicago – Energy Conservation Ordinance
-   Tokyo – new developments have to incorporate green roofs


Future Research Needs:
-   Quantified data regarding particulate matter, and the opportunity for green roofs to remove particulate
    matter at various heights
-   Research that integrates the immediate and secondary environmental benefits
-   Need to develop an understanding of the scope of implementation needed to achieve some of the
    broader benefits
-   How do Green roofs affect your property values?
-   How do you know when your green roof needs to be replaced?
-   What are the replacement costs of a green roof?



Developing a Green Roof Strategy for Waterloo: Ray Tufgar, Project Manager, Totten
Sims & Hubicki, Mike Pelton, Enermodal Engineering

      To answer the question “How can green roofs fit into the City of Waterloo’s Environmental
      Strategic Plan?”
      To gauge public knowledge and interest regarding green roofs
      To develop a plan to follow including demonstration of green roof technology

Ray discussed how the Green Roof project fits in with City of Waterloo policies such as: the Environmental
Strategic Plan, Environment First Policy and the Laurel Creek Watershed Study. Each of these
policies/plans encourages protection and enhancement of the environment, revitalizing older areas and
encouraging public outreach. As well as the opportunity to encourage Ecosystem Based Management,

                                                                                                           14
based on opportunities for partnerships and research as well as source controls for pollution. Next we
heard an overview of the project approach, the overall plan development, and how the team was evaluating
potential demonstration sites.

Green roofs provide source control, where the control of pollution is at the source. Many of the types of
stormwater control used today does not provide source control, such as conveyance measures like road side
swales or end of pipe control

Smart Growth Benefits of Green roof technology:
       Environment
         –    Green Roofs reduce overall environmental impact of buildings
       Community
         –    Enhance urban environments and revitalize downtown cores
       Economy
         –    Long-term energy cost savings
         –    More productive environments
         –    Improved durability and increased longevity of buildings



Public out Reach includes: Public Survey, Education, and Industry Focus Groups

              The Overall Plan development will include:

                Future Projects (prioritize)

                Framework to Evaluate

                Costs and Benefits

                Partnerships

                Need for Incentive Program

                Industry Involvement

                Public Involvement

                Education

                Implementation

              Link to Other Initiatives

Technology review will include evaluating available Green Roof products, identifying the opportunities
and constraints of Green Roofs, and attempting to quantify the costs and benefits of Green Roofs (both
monetary and non-monetary).

The product evaluation will include a review of application constraints, design & performance features,
material selection & construction, cost, warranty, experience and local representation. Some of the
obstacles in green roof applications are the additional structural loading requirements, the initial capital

cost, long-term maintenance requirements and the concern over roof leakage, as well as the resistance to
change.

Direct Monetary benefits of Green roofs include: Heating energy cost savings, Cooling energy cost
savings, Storm water retention, Storm water treatment (water quality), Increased property value, and Local
food production


              Additional benefits:
       Aesthetics
       Additional amenity space & habitat
       Increased roof life expectancy
       Reduced noise transmittance
       Improved air quality
       Minimization of urban heat island
       High visibility green building statement

Green roofs provide a highly visible statement of “green” values. They are also an important consideration
for Green Building Design and can improve performance as mesured by the LEED Green Building
Rating System.


              For the LEED program Green Roofs :

 Achieve 1 point for the credit:
“Exterior Design to Reduce Heat Islands - Roof”
and can contribute to additional points in 3 other credit areas :
“Stormwater Management – Rate & Quantity”
“Stormwater Management – Treatment”
“Optimize Energy Performance”

              Some considerations for Green roofs in Waterloo are:

       How important are Green Roofs to achieving sustainability?
       Are non-monetary benefits more important than monetary benefits?
       What will drive the implementation of Green Roofs?
       What government policies are needed?
       Are incentive warranted/necessary? What type(s)?

URBAN AGRICULTURE AND POLICY SESSION
           Facilitated by Elba Martell, Region of Waterloo
           Notes: Jessica Ward, City of Waterloo=



Question No.1. : Identify issues and opportunities related to Urban Agriculture/Green Roof
infrastructure in the Region of Waterloo

   •   Post 19th century health reform policies were created that moved agriculture and animal husbandry
       out of the city. (noise, health)
       Myths around animals and humans sharing/living in same space still continue
   •   Need to foster a champion. City of Waterloo is considered to be progressive
   •   Coop or organization to enable people to sell goods (economic viability)
   •   Chain of benefits means that investor (developer)may not reap benefits (i.e.: tenant)
   •   Oakville core restaurateurs want patio etc. and may use Green Roofs to increase available space
   •   Gardening projects are great to obtain funding through the “job readiness” federal funding
   •   Encourage development of green roofs with environmental points, i.e. LEADS
   •   Link urban agriculture with organic gardening. Canada has certifying agencies. (Food share
       Toronto 1st certified .organic Roof Top Garden)
   •   Think about grey water??. It contains phosphates, some heating qualities
   •   Multi-functionality… buildings that are regenerative… ALIVE??


Question No.2.: Identify challenges/barriers and how these can be reduced/eliminated

   •   Are there By-laws and health codes etc that prevent this?
   •   Review urban agriculture experiences in developing countries documented by IRDC
   •   Liability (perception of it a s a challenge). (building code changes; Provincial changes)
   •   Recycling of grey water? Look at Manitoba (CM)
   •   Look closely at limiting legislation?




Waterloo Green Roof Workshop - proceedings.doc-

                                                                                                     17
    • Resistance to change
    • Accessibility Issues?
    People can buy products even if they can’t help grow them
    Green the roof anyway and look at accessibility as a secondary issue
    • Seniors growing food
    • Food is a bonus above all of the other benefits of green roofs… life skills, capacity building
        cooperation
    • Job creation – growing, distribution
        Huge leverage
    • Think of what funding opportunities are and tailor your proposals to meet the requirements of the
        funding agencies
    • Many institutions historically had green houses i.e. City of Kitchener, City of Waterloo, and High
        Schools. We don’t have to duplicate costs.
    • People integrated back into society can work in the Urban Agriculture field
    • Urban agriculture activities bring nutritional benefits
    • Kids don’t know where food comes from. Urban agriculture in green roofs can be a source of
        education to these kids.
    • The depth of growing medium in a green roof can be a challenge for urban agriculture?
        Hydroponics
        New technologies on growing medium all the time
        These are details that can be overcome


Question No. 3 : Identify actions/strategies, participants or resources needed to implement
these next steps
    •   Aerial mapping to see how much space is possibly available of roofs (residential & industrial)
    •   Municipalities are leaders. This is necessary and good.
    •   Help Non Government Organizations to lead the change as well. (funding, awareness, resources)
    •   Urban agriculture in green roofs provides tangible benefit. People see the food they grow. ..Who
        gets other benefits?
    •   Willow Street garden: small plots – enough food for 150 + people. Still give some to Food bank
    •   City of Waterloo give a grant to Communities in Bloom for rooftop gardens
    •   Gardens on private sector land?
    •   Task force struck with representatives from Staff, politicians, community members
    •   Irrigation system. --Freeze in winter
    •   Use grey water to keep warm year round


            Top Priorities

-   Patios & roof top gardens in uptown core
-   Acreage available for growing space
-   LEEDs program should be explored
-   Look at building codes & IRDC (international research development centre)
-   There is resistance to change
-   Accessibility (cost/benefits) > not everything needs to be fully accessible

Urban Heat Island and Air Quality Session
           Facilitated by Steve Murphy
           Notes: Nada Sutic


Question No.1. : Identify issues and opportunities related to Urban Heat Island/Air Quality &
Green Roof infrastructure in the Region of Waterloo

   •   Can green roofs really impact UHI?
   •   Can green roofs make a significant difference to air quality?
   •   Will green roofs have much of a relative impact—how immediate are the needed impacts?
   •   Survivability of plants given the poor air quality conditions?

   •   Can we measure the green roof impact on the UHI? Or is it all left to modeling?
   •   Can the modeling results be translated into dollar amounts in terms of savings/costs?
   •   Value of green roofs in improving air quality at various heights: green roofs that are on top of
       high buildings will not be able to filter out particulate, because particulate does not get that high.
       This may be less relevant in Waterloo, where most buildings are not higher than three or four
       stories.
   •   Evapotranspiration argument: green roofs can reduce heat, but aren’t they contributing to
       humidity as well?
            o Experience from Europe: Peter said that in his experience in Switzerland, the green roofs
                are not necessarily more humid; we’re creating little mini-greenhouses on top of roofs;
                people congregate in these green areas because they are more comfortable.
            o Also, consider how much transpiration we’ve lost to development; so if we contribute to
                increasing transpiration, the noticeable effects are likely to be minimal.


Question No.2.: Identify challenges/barriers and how these can be reduced/eliminated Other
Arguments:
   •   The quality of life argument. Consider the analogy of buying a car—do you choose the Mercedes
       over the BMW because it’s more energy efficient, or a significantly better car? No, you buy the
       one you like more.
   •   Do we really need to get the hard data on how green roofs can reduce the UHI and improve air
       quality? We’re probably comfortable with acknowledging that there is some benefit, and we may
       as well just build the green roofs, because there are not really any negative impacts. The
       precautionary principle need not be applied here; there aren’t really any associated adverse
       impacts.
   •   Green roofs is an issue that needs to be addressed as a social issue—they can improve quality of
       life through reducing heat and improving air quality. This needs to become a larger priority.
   •   Ultimately, it comes down to: we either get the data needed, assure people that green roofs are
       good, and then go ahead and do it.
             o OR: just build the green roofs, then monitor to get the data. Show leadership.
   •   Need to develop a greater understanding of the relationship between soil-plants-water to balance
       the need for irrigation of roofs and stormwater management.

Question No. 3 : Identify actions/strategies, participants or resources needed to implement
these next steps
    •   Developers need incentives directed towards intensification (e.g. density bonus) and landscaping
        (e.g. you have to have x amount of green space and green roof counts towards that)
    •   Need flexibility in options.
             o Saying “you must put green roofs on” is not useful
             o Perhaps you could require that new development reduces its environmental impact of
                  their buildings, and offer suggestions as to how they can do that.
             o Require LEED certification. Then buildings have to be to a standard, but there are
                  various pathways to achieving that.
    •   Political will (and adhering to it). Leadership from municipalities.
    •   Incentives for municipalities to lead:
             o Kyoto Protocol
             o Commercial Building Incentive Program
    •   Life cycle costing and environmental accounting can be used to demonstrate the benefits of green
        roofs.
    •   Need more evidence of linkages between UHI/AQ and health impacts; and then demonstrate how
        green roofs can impact this.
    •   To implement green roofs, try and use the existing programs of the City. For example,
        Communities in Bloom could play a role.
    •   Raise the profile of the City: a positive image draws people in; a high quality of life keeps them
        here.
    •   Land use: get more use out of the already developed land.
The Key Points
    •   Quality of life argument
    •   Political will. Municipality should show leadership.
    •   Give developers flexibility in their options.
    •   More research needed to link UHI/AQ and health and green roofs
Top priorities
-   Green roofs can’t do it alone
-   Quantitative measures later
-   Weather, humidity and heat
-   Municipal leadership is important
-   Not exclusively green roofs – LEED program
-   Quality of life > use existing programs
-   Green roofs are one tool – there are many options that should be explored

Stormwater Management & Policy Session
             Facilitator: Scott Robertson, GRCA
             Notes: Janette Smiderle, City of Waterloo
Question No.1. : Identify issues and opportunities related to Stormwater Management &
Green Roof infrastructure in Waterloo.
    For developers to mitigate negative environmental impacts
    Ability to retrofit existing buildings
    May be more cost-efficient actions i.e. rain barrels, etc.
    Regulatory requirements
    Roof load needs to have the capability to bear green roof
    Rid roofs of standing water (WNV concern?)
    Retention of roof can be converted to hold green roof


Question No.2.: Identify challenges/barriers and how these can be reduced/eliminated Other
Arguments

Stormwater Management (swm) Benefits and Negatives

    Benefits:
       Water quantity is managed to reduce volume and peak flows in system
       Water quality improvements
       Attempt to bring system back to “natural: setting i.e. pre-development
       Erosion reduction
       Baseflow enhancement to water
       Reduced developer costs for infrastructure (less piping, pond area, etc.)
       Potential use of water captured

    Negatives:
       Cost issues
       Perception
       Regulation seen as negative


             Challenges/Barriers
    General public not highly educated on the issue of stormwater
    Change is difficult
    Lack of local evidence that stormwater can be managed on green roof
    Stormwater management guidelines (MOE) need to catch up to recognize the potential in green roof
    technology to manage stormwater
    Costs
             How Can These Be Reduced?
    Education – target developers, policy-makers, public, other stakeholders in general,
    Demonstration site and tour
    Research/real data driven results
    Incentives i.e. easier development approvals, grants, etc.
    Stop taking water for granted

these next steps


    Priority Next Steps
    Top 4:
       Education for all
       Continued local research
       Develop local demonstration site
       Develop and implement design standards for utilizing green roofs for smw (guidelines)

Others:
    Surcharge for swm costs – public, developers, etc.
    Implementation of a LEED type program
    Look at the USA background on how they came to “green” their states
    Continue and strengthen partnerships
    Leverage university interests in teaching and research
    Implement full cost accounting

Actions/Strategies, Participants Required Resources
       Regulatory bodies – all levels of government
       All stakeholders
       Incentives
       Full cost accounting right down to user for cost of swm

Smart Growth & Planning Session
             Facilitator: Mark Seasons, University of Waterloo
             Notes: John Turvey, Bottom Line Resource Group

Following a brief presentation of the concepts and strategies of Smart Growth by Mark Seasons, from U of
W, a lively idea forum on green roof concepts resulted in the following suggestions…


Question No.1. : Identify issues and opportunities related to Smart Growth & Green Roof
infrastructure in Waterloo.

Goal: Shape our Urban Form

         Brownfield redevelopment
         Intensification and mixed-use
         Core area revitalization
         Increased density along transit corridor
         Improved regional coordination


 Most people agree that unchecked development is a bad deal – for commuters, taxpayers and for the
 environment. But few can agree on how to achieve smart growth.

 National Geographic, July 2001

 Sprawl is not smart

 Greenfields are tempting targets for city growth, but costs are involved:

         Expensive to service (water, sewers, roads)
         Environmental impacts (air, water, land)
         Loss of sense of place, community
         Quality of life issues
         Accessibility and mobility difficult
         Inefficient use of resources


Question No.2.: Identify challenges/barriers and how these can be reduced/eliminated
 Smart Growth Principals:

         Mix of land use                              Compact building design
         Housing choices                              Walk-able neighbourhoods
         Distinctive                                  Sense of Place
         Preserving open space                        Farm preservation
         Preserve critical environmental areas        Reinvest in and strengthen existing communities
         Balanced regional development                Transportation choices
         Predictable, fair and cost-effective development decisions
         Stakeholder participation in development decisions

                                                                                                        23
 Question No. 3 : Identify actions/strategies, participants or resources needed to implement
 these next steps :

 Policy and Programs
 Establish a green roof design criteria that is region-wide -encompass equity and fairness
 Encourage a uniform approach from all governments
 Establish a mandate for new development
 Develop an approach for all future development
 Provide a continuum of strategies
 Address retro-fitting vs new as separate strategies
 Plan green roof approach in incremental steps
 Provide incentives for green roof development -include a bonus for people-use space
 Educate leaders and developers
 Lead with public building examples
 Provide a funding model for budgeting
Include “maintenance” as a significant budgeting concern
Research
Complete a thorough green roof cost/benefit study
           -present cost/benefits to a) owners and to b) the community
           -address technical info such as lifecycle (50 years for a green roof)
           -include study of Germany’s success
Examine the possibility of a LEEDS type program
Consider the balance of horticulture/agriculture applications
Determine what % of the public wants green roof and is willing to pay for it
Consider public perception of “roof” as a typical problem topic
           -consider alternative name such as “total green strategy”
Examine possible connects with EnerGuide and other existing government programs
-fit to them rather than develop green roof strategy in isolation
 Marketing
 Utilize green roof concept as a marketing tool.
 Promote “good corporate citizenship” through green roof concepts
 Sell the cost/life cycle
 Establish a demonstration site to raise public awareness
 Consider how to engage the public and sway public opinion
 Encourage building owners and developers to get involved
 Provide incentives and penalties approach
 Ensure that everyone has an opportunity to participate
 Encourage “ownership” of the concept by all
 Address those who support bad practices like sprawl
 Illustrate the connection between Smart Growth and Green Roof strategies


             Top Priorities:
    -    Lead through example
    -    Redesign existing policies
    -    Equity – Region wide
