                                 By Nick Stecky
                            NJS Associates, LLC
                      Certified Energy Manager
                   LEED Accredited Professional
              Objectives
   Provide an Introduction and Overview of
    Sustainability, the USGBC and LEED Family of
    Rating Systems
   Why LEED Should be of Great Interest to the
    ABMA including Manufacturers, A/E Design
    Community, Building Owners & Operators,
    Facility Managers, and Construction Managers
   How to identify LEED Credits Relevant to
    ABMA Members
          General
   Introduction/Discussion
As we go through this presentation, here‟s several points:
 LEED is becoming nationally accepted at local, state and Federal
   levels
 The engineering community has the knowledge and skills that
   can add significant value to a LEED design team.
 LEED has a value to the engineering community, both as
   owners/operators of facilities or as design team members.
 LEED can enable new value messages for manufacturers‟
   products
 It is a WIN-WIN proposition for us all.
           General
    Introduction/Discussion
   Green Buildings are a process, not a collection of
    technologies and/or parts.
   Encourage participation & membership in USGBC and
    its local Chapters.
   Encourage attendance at LEED Workshops and
    Professional Accreditation.
   Encourage building owners/operators to register and
    certify projects.
      Sustainability Defined
   ASHRAE defines Sustainability as “Providing for the
    needs of the present without detracting from the
    ability to fulfill the needs of the future.”

   Brundtland Commission of the UN:
    Development is sustainable “if it meets the needs of
    the present without compromising the ability of
    future generations to meet their own needs.”
   Environmental Impact of
          Buildings*
Americans spend as much as 90% of their time indoors.
 65.2% of total US electricity consumption
 more than 36% of total US primary energy use
 136 million tons of construction & demolition waste in
  the US
 12% of potable water in the US
 make up 35% of the municipal waste stream
 40% (3 billion tons annually) of raw materials use
  globally

* commercial & residential
    Environmental Impact of
           Buildings
 Emissions of green house gases
  contribute to global climate change and
  acid rain
 Represent a significant use of land,
  natural resources and impacts rivers
  and coastal environments
Reduced Environmental Impact
Energy Saving actions mean reducing:
 1.21 billion tons of CO2
 4.4 million tons of NO
 7.2 million tons of SO2
 129,000 tons of particulate
 34.6 tons of mercury
 57.6 tons of cadmium
 3.2 tons of lead emissions
Equals planting 3.8 billion trees or removing pollution of
  250 million mid-sized cars
Political Impact Potential ?
Aggressive adoption of LEED NC and EB
 could lead to the elimination of oil
 imports from the Middle East?
    Sustainable Design
High Performance Buildings
 High Efficiency Buildings
Integrated Building Design
     Green Buildings


All Different Terms but Basically
 Conveying the Same Message
Characteristics of Green Buildings
    Optimal environmental and economic
     performance
    Increased efficiencies saving energy and
     resources
    Satisfying, productive, quality indoor spaces
    Whole building design, construction and
     operation over the entire life cycle
    Fully integrated approach - teams, processes,
     systems
Characteristics, Yes but “What
    is a Green Building?”
           Green Buildings
Are designed and constructed in accordance with
   practices that significantly reduce or eliminate the
   negative impact of buildings on the environment and
   occupants.
Five broad areas:
 Sustainable Site Planning
 Safeguarding Water and Water Efficiency
 Energy Efficiency and Renewable Energy
 Conservation of Materials and Resources
 Indoor Environmental Quality
All relate back to the previous definition of Sustainability
All of These are Contained in
      the LEED Standard

     Leadership in Energy and
       Environmental Design
Sustainable Buildings Defined
    The British Research Establishment Environmental
     Assessment (BREEAM) was launched in 1990 and is
     increasing in its use
    Canada‟s Building Environmental Performance
     Assessment Criteria (BEPAC) began in 1994 but
     never fully implemented due to its complexity
    The Hong Kong Building Environmental Assessment
     Method (HK-BEAM) is currently in Pilot form
    The USGBC LEED Family of Programs
    State and Regional guides include High Performance
     Building Guidelines in NY and Pa‟s Guidelines for
     creating High Performance Buildings
Benefits of Green Buildings
   Environmental Benefits - reduced impacts on
    natural resource consumption
   Economic Benefits - improves the bottom line
    - savings thru efficiency and productivity
   Health and Safety Benefits - enhanced
    occupant comfort and health
   Community Benefits - minimize strain on local
    infrastructures and improve the quality of life
Economic Benefits of Green
   Competitive first costs if integrated design process is
    used. Achieved thru the synergies between
    disciplines and technologies
   Lower construction costs- thru reduced site
    preparation and less waste disposal
   Reduced Operating Costs primarily thru energy
    savings - lower energy bills by 20% to 50%
   Optimized life-cycle economic performance Vs
    minimum first cost emphasis
 Economic Benefits Cont‟d
 Increased building valuation - use the
  formula: asset value increases at ten
  times the reduction in operating cost on
  an annual cost per sq ft basis
 Decreased vacancies, improves tenant
  retention and gives a marketing edge
 Reduced liability, improves risk
  management - i.e. no mold
    Productivity Benefits
 Improve Occupant performance -
  employee productivity rises, students
  grades improve
 Absenteeism is reduced
 Retail Stores have observed measurable
  improvements in sales in stores with
  daylighting
Why is Productivity
   Important?
 Occupants’ Salaries are 85% of the Cost of Office Building
                         Operation
        Acceptance of LEED
   Federal Use - GSA, The USAF, US Army Corps of Engineers,Dept
    of state, DOE, EPA, FEMP
   Many states have established LEED initiatives: NY, NJ, Pa,
    Maryland, RI, Conn, Mass, Cal and more.
   Many cities have adopted LEED Including Seattle, Portland,
    Chicago, Fairfax Va, Arlington Va, Austin, Santa Monica
   Many local communities and municipalities adopting LEED
   Higher Ed adoption includes Colorado College, The NJHEPS
    which represents all NJ Higher Ed, Conn College, Emory College,
    Evergreen State, Furman U, Georgia Institute of Technology,
    Hardvard U, Lewis & Clark, MIT, Montana State, Mt Holyoke
    College, Tulane and many more.
     Corporate Acceptance
Many, Diverse Major Corporations are pursuing LEED projects
  and/or promoting LEED:
 Johnson & Johnson - corporate LEED EB Pilot
 Phillips Lighting
 National Geographic - 1st LEED EB Certified
 Johnson Controls - in the first group of LEED NC certified
 PNC Financial Services Group
 Turner Construction
 USAA Realty
 Herman Miller
 Steelcase
 CalPERS
 and too many more to name
Op/Ed on LEED Acceptance
There‟s a groundswell of acceptance taking place. When LEED was
  first introduced several years ago, there was reluctance to
  accept it. It represented a new way of looking at the design,
  construction, operations and disposal of facilities. It called for a
  raising the bar which many have been slow to accept. Many
  questions about higher first costs, paybacks, overall benefits,
  ability of the design community to deliver, doubts about the
  technologies involved etc. The perception was that Green
  Buildings were too futuristic, not obtainable and required too
  many tradeoffs to be able to deliver a practical, efficient facility
  where people could live, work and play.
Op/Ed on LEED Acceptance
Some elements of these doubts remain, especially the
   financial benefits question. However, as we gain
   experience with Green Buildings, we are developing
   the experience and the data needed to resolve these
   doubts.
I believe that the time is nearing when Green Buildings
   will be accepted as being so obviously better that the
   uncertainties of going green will simply disappear.
   History teaches us that better will always displace
   good.
              The USGBC
Mission Statement

The USGBC is the nation‟s foremost coalition of leaders

LEED for New Construction
    Points Categories
 Sustainable Sites (22%)
 Water Efficiency (8%)
 Energy & Atmosphere (27%)
 Materials & Resources (20%)
 Indoor Environmental Quality (23%)


Note: that engineering skills are applicable to as many
  as 58% of total available points on Water, Energy
  and IAQ.
May „04 Energy User News article by Peter
 D‟Antonio, Entitled “The LEEDing Way”

The Article analyzes the activity in Energy & Atmosphere, E&A,
  and Indoor Environmental Quality, IEQ, for the first 53 LEED
  Certified Buildings:
 Regarding E&A, average points earned is only 5.3 out of the possible
  17!
 This is the lowest % achieved in any of the five points categories! So
  although E & A is the largest plum, few appear to be taking advantage
  of it.
 Renewable Energy points are earned in less than 10% of the certified
  buildings
 Regarding IEQ points, ventilation effectiveness and controllability are
  achieved in less than one third of buildings.
  This EUN Article provides support for the
 proposition that we in the engineering and
    energy industries and others are not
maximizing our potential contributions to LEED
                  Buildings


       Hence, there is a significant
    opportunity for our professions to
     take on the larger role that we
     should have in Green Buildings‟
        design, construction and
               operations.

Why LEED EB is so Important
     Besides the Environmental Impacts and Benefits
       introduced previously, it‟s simple:

     There are many more existing buildings than
       those in New Construction. Existing Buildings
       have the potential to be a much more overall
       significant contributor than New Construction.
Overview of LEED-EB
LEED-EB Rating System Goals
    Help building owners upgrade and
     operate their buildings in a sustainable
     way over the long term
     – Avoid the “saw tooth” approach (upgrade,
       decline, upgrade, decline …)
    Support high productivity by building
     occupants
      Benefits of LEED-EB
   Communications
    – Helps building managers, operators, and service
      providers communicate the importance of effective
      ongoing building operation and maintenance to
      decision makers in their organization

 ASHRAE and USGBC


 In 2002, both organizations
   entered into a Partnering
 Agreement and the ASHRAE
GreenGuide was developed to
assist USGBC in their efforts at
promoting sustainable design.
       ASHRAE GreenGuide
   Developed to provide guidance on how to apply
    green design techniques.
   Not developed to motivate use of green designs
   The purpose is to help the designer of a “green
    design” with the question of “What do I do next?”
   Organized to be relevant to the audience, useful,
    practical and to encourage innovative ideas from the
    design team.
   A reference guide incorporating “Green Tips.”
It is Greener on the Other Side
