Role of the Construction Industry
  Buildings use:
         30% all energy
         60% of all electricity
  Buildings are responsible for:
       49% SO2 emissions
       25% NO2 emissions
       10% particulate emissions
  Cement production: one tonne of cement
  results in the production of about one tonne of
  CO2
  Construction waste accounts for about 1/3 of
  landfill
       Green Building Response

Green building is design that incorporates
  improved environmental performance
Claims of Green Building have led to systems of
  measurement
BREEAM – British Research Establishment
  Environmental Assessment Method
BEPAC – Building Environmental Performance
  Assessment Criteria
LEED – US Green Building Council’s Leadership
  in Energy and Environmental Design Green
  Building Rating System
         U.S. Green Building
               Council
North America’s foremost coalition of leaders
from across the building industry working to
promote buildings that are environmentally
responsible, profitable, and healthy places to live
and work.

The organization’s purpose is to:
   Integrate building industry sectors
   Lead market transformation
   Educate owners and practitioners
  What is “Green” Design?
Design and construction practices that significantly
reduce or eliminate the negative impact of buildings
on the environment and occupants in five broad
areas:
 Sustainable site planning
 Safeguarding water and water efficiency
 Energy efficiency and renewable energy
 Conservation of materials and resources
 Indoor environmental quality
               LEED BC

 LEED BC Draft by Ray Cole and Ian
  Theaker
   Under review by BC, City of Vancouver,
    GVRD, BCBC and other stakeholders
   Harmonizes with Canadian standards and
    references
            LEED Canada
 Sustainable Building Canada Committee
   Under auspices of RAIC
   Recommended assessment tool : LEED;
    technical advisory committee chaired by
    Kevin Hydes
   Referring to LEED BC – in process of
    harmonizing with Canadian standards and
    possibly “BREAM Greenleaf”
       Why Was        LEED TM

          Created?
 Define “green” by providing a standard
  for measurement
 Prevent “greenwashing” (false or
  exaggerated claims)
 Use as a design guideline
 Promote whole-building, integrated
  design processes
   Why Was LEEDTM Created?

 Recognize leaders
 Stimulate green competition
 Establish market value with recognizable
  national “brand”
 Raise consumer awareness
 Transform the marketplace
          Principles of LEED

 Ongoing consensus development process
  involving many stakeholders
 Begins to define “green buildings”
 Tool to introduce, promote and guide
  integrated building design
 LEED will standardize green design and
  institutionalize integrated design practices
             Use of LEED

 USA: GSA, US Air Force, US Army Corps of
  Engineers, Dept of State, DOE, EPA, US Navy
 Cities: Seattle, Portland, Austin, Chicago
 LEED BC: BC Government, GVRD, City of
  Vancouver, Whistler Municipality
 LEED Canada: SBCC endorsement

The primary objective of LEED is to transform
  existing building markets so that sustainable
  design, construction and operations practices
  become mainstream

LEED Credit Format & Structure
 Each credit identifies the following:
   Intent
   Requirements
   Technologies and Strategies

 Offers market transformation and
  educational information rather than simply
  a statement of required elements
         LEED Credit Intent
Conveys the goals and objectives of the
  credit
Lists the environmental benefit and
  preferred outcome
Assists in educating owners and building
  professionals
Aids in interpretation of credit compliance
    LEED Credit Requirement

Identifies specific elements needed to
  achieve the credit
Defines actionable items
Where practical, includes components of
  referenced standards and critical
  compliance issues
             Sample Prerequisite:
             Energy & Atmosphere
                Prerequisite 2
Intent
   Establish the minimum level of energy efficiency for the
   base building and systems

Requirement & Submittals
  Design to meet building energy efficiency and
  performance as required by ASHRAE/IESNA 90.11999
  or local energy code, whichever is more stringent.
           Sample Credit
 Materials and Resources Credit 4
         Recycled Content
Intent
   Increase demand for building products that have
   incorporated recycled content materials, therefore
   reducing the impacts resulting from the extraction of new
   materials.

Requirements and Submittals
  Credit 4.1 Specify a minimum of 25% of building
  materials that contain in aggregate, a minimum weighted
  average of 20% post-consumer recycled content
  material, OR, a minimum weighted average 40% post-
  industrial recycled content material.
  LEED Credit Technologies &
         Strategies

Includes a summary of recommended
  technologies and strategies to meet the credit
  requirements

Case Study: BC Gas, Surrey BC
BC Gas Operations Centre

The Surrey campus comprises two buildings: an operations centre
of 170,000 square feet, and a 30,000-square-foot training centre;
parking totals 600 cars.

The buildings are oriented to maximize useable site area, break up
large floor plates and minimize exposure to low-angle east and
west sunlight. Angled heat-absorbing sun screens minimize heat
gain from those exposures. Direct southern sunlight is shaded and
light shelves are introduced to maximize indirect daylighting.
North glazing is also maximized to take advantage of diffused
daylighting.

Daylight Penetration
Opening windows in
conjunction with atriums
provide natural ventilation.
Atriums also provide identity
to user functions, increase
daylight penetration and
promote vertical circulation
with open stairs. Power, data
cabling, and supplemental air-
conditioning are supplied
through raised floors. Indirect
lighting reduces glare on
computer displays.
