Sustainability lens

  • Need for consistent and

comprehensive sustainability evaluation framework: should incorporate LCA, LCC in regenerative context

  • Able to be applied in all four stages of

building lifecycle

  • Go beyond the building shell:

neighbourhood/precinct

Campus as sustainability test-bed

Universities uniquely suited for this role

  • Single (owner-)occupiers
  • Public mandate
  • Teaching
  • Research

Develop integrated campus-scale systems

  • Demonstration and research
  • Engage and train students; develop new

curricula and programs

CIRS

~14 million sq. ft. ~270 core buildings ~ 300 hectares

UBC’s Climate Change goals (Mar, 2010)

  • achieved Kyoto targets (-6%) for core

academic buildings in 2007 (with 35% growth in floorspace)

  • New targets:
  • 33% by 2015
  • 67% by 2020
  • 100% by 2050

UBC Campus Steam System

Size of energy challenge:

  • eliminate fossil fuels
  • no new electricity transmission lines

to campus

  • ~35% growth in research and

residential floorspace by 2030
