• Construction Activity Pollution Prevention• Water use reduction• Commissioning• Minimum Energy Performance• Building metering• No CFCs• Storage and collection of recyclables• Minimum IAQ performance• No Smoking• Minimum acoustic performance
Key Concepts in Eligibility and Implementation
o LEED Campus Program for projects on shared site, allows for campus-wide credits or certification of groups of similar buildings. Do not have to use.Schools, hospitals, resorts with several physically distinct structures as defined by ENERGY STAR can do a single certification without using campus.
o Renovations and AdditionsRenovations use NC or CI depending on scope. In additions, energy systems must be separate or part of a central system outside of the project building or space.
Key Concepts in Eligibility and Implementation
o Incomplete spaces and Tenant Sales and Lease AgreementsRequired commitments from owners and tenants for spaces in the building not built out as part of the project. Allows for project to take credit for green features planned for the spaces.

c) The trade off is that either way, the refrigerant will have a harmful impact to the environment. This is because some refrigerants have a higher ODP and a low GWP, while others have a higher GWP and lower ODP.
d) The trade-off is that refrigerants will either contribute to global warming or contribute to depleting the ozone layer unless EnergyStar equipment is used.

Who Cares?The Montreal Protocol was signed in 1987, signifying the intent by multiple world leaders to reduce the effects of global warming and the thinning ozone layer by eliminating the use of ozone depleting substances, such as harmful refrigerants or CFC’s.

Hard CostsLEED vs. Non-LEED
There is no significant difference in average cost of green buildings as compared to non-green buildings
Davis Langdon’s “Costs of Green Revisited” Study
Soft costsBy LEED Certification Level:
Source: Analyzing the Cost of Green – The American Chemistry Council
Improved performanceo New Buildings Institute study showed average EUI in
green buildings was 24% lower than typical buildings
o General Services Administration evaluation of federal green buildings:• 13% less maintenance costs• 26% less energy• 27% higher occupant satisfaction• 33% lower CO2 emissions
Role of Codes
Require green features or
certain performance
Limit innovation, require non-
green features

Basicso Review all Referenceso Look for definitions and
concepts list in Specifications
o Make flashcards, lists, diagrams
o Review notebook from training and study tools

know:o Intent Key Requirementso Reference Standardso Terms
ApplyNext – Case studieso Find case studies
• USGBC Project• High Performance Building database• Cascadia GBC
o Review descriptions and identify which principles in the “Specifications” list green features described contribute too.
o Look for synergies and relationships
