• International Green

Construction Code. IgCC

was developed in conjunction

with the American Institute

of Architects (AIA) and the

American Society for Testing

and Materials (ASTM). lgCC

is coordinated with the other

ICC model codes and is

intended for adoption and use

with those codes. It provides

criteria for site development

and land use, material resource

and conservation, energy

efficiency and air quality,

water resource conservation,

indoor environmental quality,

and building operation

and maintenance, as well

as provisions for existing

buildings. The document also

provides adopting agencies

with a variety of provisions

upon which they can base

their adoption to best address

their energy needs. The IgCC

references ASHRAE Standard

189.1 as an acceptable path to


• ICC 700-2008 National Green

Building Standard. ICC 700-

2008 exceeds the 2006 IECC

by a minimum of 15%. This

standard defines green building

for single and multifamily

homes, residential remodeling

projects, and site development.

Outcome-Based Codes

Progressive states and jurisdictions

are beginning to select outcomebased

energy codes to achieve

energy efficiency goals. Unlike

traditional codes in which a

building or home is compared to

a theoretical baseline, outcomebased

codes measure actual energy

use once a building is occupied,

commissioned, and operating.

Outcome-based codes are then

satisfied not only through energyefficient

design and construction,

but through operational and tenant

energy use as well. Resource 14

in this chapter, the New Buildings

Institute (NBI), offers guidance and

numerous resources on outcomebased

codes, including their

development and adoption.


It is important to select an energy

code that will achieve the goals

established by a specific state or

jurisdiction in the most efficient

way possible.

Many states choose

to adopt a model

energy code because

they are developed

by industry

professionals and do

not require additional

state or jurisdiction

resources to create.

Model energy codes should be

adopted without amendments

for total access to resources. For

greater energy savings, consider

the adoption of a green building

code or beyond-code program. If

a statewide green building code

is not feasible, allow counties or

municipalities to enforce a local

green building program.
