History

May 11, 2014 The 2012 IECC and ASHRAE 90.1-2010 become effective statewide.
November 10, 2011 As a direct result of BCAP’s DOE-funded Compliance Planning Assistance (CPA) Program, the Delaware Division of Energy and Climate convenes the first meeting of the Delaware Energy Code Coalition. Made up of a diverse group of state and local stakeholders, the Coalition will be responsible for advising on energy code implementation, infrastructure, and updates, as well as carrying out the tasks necessary to ensure greater compliance with the energy code. The coalition’s formation was one of the major recommendations developed by BCAP in its Delaware Gap Analysis Report.
July 2010 The 2009 IECC and ASHRAE 90.1-2007 become effective statewide. The Delaware Energy Office (DEO) partners with BCAP and Newport Ventures to offer six code training sessions throughout the state in May and June.
July 2009 Delaware passes Senate Bill 59, mandating the adoption and enforcement of the 2009 IECC and ASHRAE 90.1-2007 statewide. Enforcement is currently the responsibility of local jurisdictions, but the Delaware Energy Office is currently drafting rules to broaden the state’s role in assisting in the implementation.
July 2004 The state adopts the 2000 IECC for new residential dwellings of three stories or less in height. For all other buildings, the 2000 IECC and its 2001 supplement (with its reference to ASHRAE 90.1-1999) are in effect.
1995 State Bill 83 adopts the 1993 Model Energy Code (MEC) statewide.
1979 The Delaware legislature passes Senate Bill 321, which establishes a minimum code for energy conservation. The legislation provides that no county or municipality may adopt a building or plumbing code that contradicts the energy requirements of the Model Code for Energy Conservation in New Building Construction (MCEC), a model code based on ASHRAE/IES 90-1975.
