Energy Efficiency
Primary Resources (cont.):
Refrigerants Very useful, but damaging to the environment Trade-offs between performance, ozone depletion and
contribution to GHG
Montreal Protocol bans the production of CFCs and
phases out HCFCs
The replacements for CFCs and HCFCs are often
potent greenhouse gases and are less efficient
Under LEED, new buildings cannot use CFCs and
existing buildings must phase out CFCs before project completion

Energy Efficiency
Strategies:
Identify passive design opportunities Use the sun and wind to heat, cool and illuminate Consider building orientation, material selection and
window placement
Address the building envelope Use appropriate insulation in walls and roof, high
performance glazing to minimize heat gain and loss
Ensure that the building is properly weatherized
