3. What is Green Design?
To significantly reduce or eliminate the negative
impact of buildings on the environment and on
the building occupants, green building design
and construction practices address: sustainable
site planning, safeguarding water and water
efficiency, energy efficiency, conservation of
materials and resources, and indoor
environmental quality.
-USGBC

4. What is Green Design?
How do we love all children of all species for all
time?
-William McDonough

5. What is LEED?
Leadership in
Energy and
Environmental
Design
The LEED Green Building Rating System™ is the
nationally accepted benchmark for the design,
construction, and operation of high performance
green buildings.

16. Integrated Project Planning
– Engage key members of project team
• Pre-construction meeting
– Goals, timetables, responsibilities
ID 1.2 Integrated Project Team 1pt.
ID 1.3 Design Charrette 1pt.

17. Durability Plan
ID 2.1 Detailed Durability Plan; (Pre-Construction) Mandatory
ID 2.2 Third-party verification of Durability Plan 3 pts

18. CIR’s and ID’s
Credit Interpretation Request— an alternative way of achieving the
same intent as an existing LEED credit. It is achieved by
requesting permission to meet the “intent” of a credit using an
approach that is different from the stated “requirements,” or simply
a clarifying question not addressed in the rating guide.
Innovative Design (ID) — a way of earning one or more LEED
points for technologies or strategies that are not included in the
Rating System but offers substantial environmental benefits. It is
achieved by requesting permission for a credit / measure that is not
included in the current rating system or going above and beyond an
existing credit.

19. What is LEED-ND?
A LEED rating system being developed through a
partnership with
– Natural Resources Defense Council (Smart Growth)
– Congress for the New Urbanism
A rating system that combines elements of smart growth,
urbanism, and green building
