LEED Session Summaries and Presentation Slides

Bull Housser – Telus Garden Building – Goran Ostojic, Integral Group – Presentation here

  • Currently only LEED platinum building in Vancouver
  • Built for the long term in mind (>30 year lifetime)
  • Thermal Comfort in mind in design

o   radiant heating and cooling: embedded piping throughout structure

o   low maintenance, low grade energy

o   displacement ventilation, air introduced from low levels and exhausted at top

o   results in more comfort

  • Potential data exchange in future with Telus data centre (existing building) which discharges waste energy

o   can cover up to 80% of primary heating and cooling

LEED in Canada: where we’ve been, what’s coming and what it means to you – Mona Lemoine, HCMA Architectural Design

LEED v4 summary

  • LEED building standard  adapted from UK system
  • LEED v4 has been updated to cover more industries and types of buildings
  • Changes include

o   certification dependent on human health, quality of life rather than points

o   types of materials used, eliminating materials with potential long term toxic effects

o   no more Canadian requirements, LEED is global now and therefore Canadians have access to better tools

o   paperwork and application process simplified to streamline certification process

o   while Canadian vs. American market aren’t different there are still alternative compliance and standard paths (ie. wet west coast vs. dry arid areas)

o   2009 LEED registration ends on October 31, 2016

o   Can register now for LEED v4 for the same price as 2009 version

City of Surrey Library – Surinder Bhogal – Presentation here

  • 77,000 sq. ft. (from previous library, 10,000sq. ft.)
  • setting is close to all major transit lines, linked to the bike network to enable alternate forms of transportation to visitors and employees
  • 50 staff members, approximately 30% take public transportation to work
  • Concrete is used as a major building material in the library

o   energy efficient construction material

o   building envelope and slabs

o   expected life expectancy of over 50 years

o   acts as a thermal mass: collects energy and releases it throughout the day

  • Internal materials (paint and adhesives) are low emitters, carpet is wool to minimize off gas (ie. no new house or car smell)
  • 15% of material used is recycled material
  • 77% of materials were diverted from landfills
  • Lighting is LED and compact fluorescent, motion sensor lights everywhere
  • 44% of traditional energy is saved in the design of the building, including mechanical energy
  • Glazing at north and east windows allow natural light to be used, with outward/vertical shading to control glare and heat in the building
  • Roof is planted with 40% sedum, manages stormwater runoff and CO2 emissions

o   white to reflect solar energy away from the building

  • Cost to build library to LEED gold was only slightly more than building to Code

UniverCity – SFU Community Trust, Dale Mikkelson – Presentation here

  • 9000 people living in residential community at SFU
  • residents work all over the lower mainland, public transportation
  • Goals of Trust fall under “Four E’s”: Environment, Equity, Economy and Education
  • Environment – performance based certifications

o   1st comprehensive zoning bylaw done through City of Burnaby

o   target of 40% less water use, 30% more energy efficient, less hazardous waste

o   green building bylaw is waived if building achieves LEED Gold

o   100% stormwater managed, no redundant infrastructure (backup system), water delivered to existing tributary: but results in few LEED points as the water is not re-used

  • Economy and Equity

o   20% discount for faculty members, sold below market rates

o   affordable rentals

o   some reserved specifically for graduate students with children

o   mixed commercial and residential rental units

o   return funds back to SFU for endowment

o   1st fully fair trade organic Starbucks

  • Education

o   trust funds 2 interns a year

o   university childcare system:

  • living building challenge, life after LEED
  • zero impact challenge, net positive to community
  • entire SFU project 18% below budget
  • potential move to gondola transit system, eliminating need for articulating b-line bus to SFU
