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.

CATEGORIES OF LEED

LEED-EB existingbuildings

Commercial Buildings

Residential

• In pilot since late 2005, due to launch later this year – Green Build

• Open to any qualifying projects

• Follows residential code – 3-stories and below

• Concurrent pilots for mid-rise (4-6) and high-rise (7 and up) residential buildings running now

• Differs from other LEED products in delivery system – administered locally by ‘Providers’

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.

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

What is ENERGY STAR?

• Third party labeling system for homes that meet the EPA criteria.

• Home Energy Rating System (HERS) accredited professionals

• HERS Index: Reverse scale 100 – 0

100 = code minimum (worst legal)

0 = net zero energy

85 (or lower) = ENERGY STAR

Design and install insulation to minimize thermal losses.
