State Owned / Funded Buildings

All state-funded new construction and major renovation projects over $1,000,000 must be built in accordance with LEED guidelines. Executive Order #2005-4

Adoption Process

The state energy code is evaluated for revisions or modifications every three years. The new code requirements are adopted at the beginning of each state building code cycle (which corresponds with the three-year cycle of the Building Officials and Code Administrators [BOCA] International, National Building Code [NBC]).

Enforcement Process

The local code official is designated to enforce the state energy requirements. Enforcement is completed through plan review and inspections. The Bureau of Construction Codes, Department of Consumer and Industry Services, interprets the code and enforces it in those jurisdictions in which the Bureau has enforcement responsibilities.

Compliance Process

Compliance is determined by plan review and inspection by the local code official or state building official.

Background

Prior to June 22, 1977, the state of Michigan had no building energy efficiency requirements. As of that date, the state adopted ASHRAE/IES Standard 90-1975 statewide. On July 27, 1985, the state adopted ANSI/ASHRAE/IES Standard 90A-1980 statewide.

SB 719, signed in early January 1996, repealed the 1995 adoption of the 1993 MEC. The legislation directed the state construction code commission to, by April 1, 1997, provided cost-effective standards and establish a program to provide home buyers with energy rating information. A 10-member ad hoc committee was established to assist with these efforts.

The Michigan Uniform Energy Code Part 10 Rules were adopted March 31, 1999. In 2002, the Department of Labor & Economic Growth (DLEG) established a committee to review and update Michigan's Uniform Energy Code. After review and promulgation of the code, the Ingham County Circuit Court issued an injunction to halt the February 28, 2005, effective date of the rules in response to a lawsuit by the Michigan Association of Home Builders (MAHB). The new code has since been pending litigation for the last three and a half years.

On October 24, 2008, the judge presiding over the litigation dismissed the MAHB complaint and dissolved the lawsuit, making the rules effective immediately. Therefore, every unit of government enforcing the single state construction code must apply the 2003 Michigan Uniform Energy Code to newly issued permits. The 2003 MUEC is based on the 2003 International Residential Code (IRC) with references to the 2004 IECC supplement.
