PART1—SCOPE AND APPLICATION
These regulations shall be known as the Green Construction Code of [NAME OF JURISDICTION] hereinafter referred to as “this code.”
The purpose of this code is to provide minimum requirements for the siting, design, construction, and plans for operation of high-performance green buildings to: reduce emissions from buildings and building systems; enhance building occupant health and comfort; conserve water resources; protect local biodiversity and ecosystem services; promote sustainable and regenerative materials cycles; enhance building quality; enhance resilience to natural, technological, and human-caused hazards; and support the goal of development that meets the needs of the present without compromising the ability of future generations to meet their own needs.
This code is intended to provide the technical basis of mandatory building codes and regulations for high-performance green buildings that are broadly adoptable by national and local jurisdictions.
This code contains requirements that address site sustainability, water use efficiency, energy efficiency, indoor environmental quality (IEQ), materials and resources, and construction and plans for operation. This code applies only to the following building projects:
1.New buildings and their systems.
2.New portions of buildings and their systems.
3.New systems and equipment in existing buildings.
4.Relocated existing buildings and temporary structures where specified in this code.
The provisions of this code do not apply to the following:
2.Multifamily dwellings of three stories or fewer above grade.
3.Manufactured houses (mobile homes).
4.Manufactured houses (modular).
5.Building projects that use none of the following:
(Informative note: The provisions in Appendix J for residential and multifamily construction apply where adopted by the authority having jurisdiction.)

1.Prescriptive Option (x.4) or
2.Performance Option (x.5).
