  1. SUSTAINABLE BUILDINGS A New Approach to Building CAUBO 2006 John Metras, P.Eng. University of British Columbia

  2. Overview • What is a sustainable or “green” building? • What is LEED®? • Why build green? • How much does it cost? • Case Study: UBC Life Sciences Centre • Challenges • Keys to Success

  3. What is a sustainable building? • Uses key resources more efficiently – energy, water, materials and land • Reduces ecological loading – greenhouse gases, ozone-depleting substances, wastes • Creates healthier environments for people to live, work and learn • Has lower overall lifecycle costs

  4. What is LEED®? • Leadership in Energy & Environmental Design • Rating system for developing high performance, sustainable buildings • Voluntary, consensus-based, well recognized • Developed by US Green Building Council • Adapted by the Canada Green Bldg Council

  5. LEED® Point System

  6. LEED® Rating Levels

  7. Applications for LEED®

  8. Why use LEED®? • Provides a common and consistent framework for defining a “green” building • Is relatively simple to implement • Is not overly prescriptive • Can be adapted for local climates and standards • Provides legitimacy of 3rd party certification • Is gaining momentum as the accepted rating system

  9. LEED® Projects in Canada

  10. Positioning of LEED® in the Market

  11. Green Building Benefits • 25-60% energy savings • 30-50% water savings • CBIP financial incentive • Improved worker productivity – due to improved lighting and thermal comfort • Reduced sick time from allergies, asthma & respiratory illness • Lower life-cycle costs

  15. Case Study:UBC Life Sciences Centre

  16. UBC Life Sciences Centre • Architects: Bunting Coady/Diamond & Schmitt • Construction Manager: Ledcor • Area: 52,000m2 / 560,000ft2 • Cost: $110 million • Occupants: 2,654 staff, researchers, students • Energy: 28% less than standard building • Water: 50% less than standard building • LEED® Rating: Gold

  17. UBC Life Sciences Centre Sustainable Site • Brownfield site • Bicycle storage & changing facilities • No new parking spaces • Re-vegetated 87.5% of landscape with native and adapted plants • Erosion & sediment control during construction

  18. UBC Life Sciences Centre Water Efficiency • Dual-flush toilets • Waterless urinals • Sensor-controlled faucets • 87.5% of irrigation system to be de-commissioned after 1 year plant establishment period

  19. UBC Life Sciences Centre Energy Efficiency • 28% better than ASHRAE 90.1 standard • Annual energy savings of 6.4MWh, equal to $180,000 • Heat recovery systems • Demand ventilation • Maximum natural lighting • Motion sensor lighting controls

  20. UBC Life Sciences Centre Materials & Resources • Local building materials, 10% recycled content • 80% of construction waste recycled or salvaged • Green housekeeping practices • Comprehensive recycling and composting program

  21. UBC Life Sciences Centre Indoor Environmental Quality • Low-emitting materials • CO2 monitoring • BMS for environmental control and monitoring • Displacement ventilation • Maximum natural lighting • Green housekeeping program

  22. Other Green Buildings at UBC • CK Choi Building (1994) • Liu Centre (1999) • Technology Enterprise Facility III (2003) - LEED® Silver Certified • ICICS Building (2005) • Frederick Kaiser Building (2005) • Aquatic Ecosystems Research Lab (2005) - LEED® Silver Certified • Buchanan “D” Block Renewal (2006) - LEED® Silver (planned)

  23. Challenges • High expectations of building performance • Acoustics • Waterless urinals & dual-flush toilets • Motion sensor activated lighting • Operating systems at optimal level

  24. Keys to Success • Incorporate green principles at the beginning of the design process • Involve operations staff early in the design process • Avoid unmanageable complexity in building systems • Undertake a thorough commissioning process • Ensure staff are properly trained in building system operation

  25. Summary Why Build Green? • Proven environmental & health benefits • Minimal initial cost premium • Life-cycle cost savings
