Second, PL 517 modified and improved the oversight and training of code enforcement officers. (Pursuant to existing law, enforcement of the code is voluntary in municipalities having fewer than 4,000 customers, representing about 40% of the population).
First, Public Law (PL) 391 established that the Maine Uniform Building and Energy Code (MUBEC) must update the code from the 2009 IECC to the 2015 or a newer version, that it must be kept up to date with the latest version of the IECC, and required that it be applied in every municipality in Maine, regardless of population. In 2019, the Maine Legislature enacted three important amendments to building codes. It applies to all commercial construction projects 10,000 square feet and larger and all residential projects that are 10,000 square feet and larger and four stories or higher. The District also has a Green Construction Code that enhances energy efficiency requirements in addition to the energy code. The codes also include an alternative compliance pathway for net zero buildings, including LEED Zero Energy and LEED Zero Carbon, for both commercial and residential construction ( link). The high gas efficiencies required by this amended code remove the need for the energy efficiency utility to incentivize new construction gas projects, but moves the focus to strategic electrification for HVAC and water heating. Key elements of the new code require ENERGY STAR products for a variety of technologies and stringent gas efficiency. ( Link)īoth the commercial and residential building energy code was amended to strengthen energy efficiency in the District. Applicability and provisions for the prior editions of the code, (for Permits issued, Applications Filed, Tenant Layouts and Permit Revisions) will be governed by the Transitory Provision stipulated in section 123. The 2017 DC Construction Code took effect on May 29, 2020.
The 2017 DC Construction Codes consist of the 2015 International Code Council (ICC) family of model codes, the 2014 National Electrical Code, and 2013 ASHRAE 90.1, as amended by the District of Columbia Municipal Regulations (DCMR) Title 12, Sections A through M. Washington DC's energy codes are mandatory across the District. The 2018 IECC is the minimum building energy code for the construction of state-owned facilities.įactory-built nonresidential structures and hotels, motels, and multi-family dwellings in areas of the State where no building codes exist, must meet the 2015 IECC. The construction of health care and K-12 school facilities is regulated by the State of Colorado Division of Fire Prevention and Control which has adopted the 2015 IECC for these facility types. More than 60 jurisdictions have adopted the 2018 IECC so far, with many more in the process or under consideration. More than 2.7 million Coloradans, or 48% of the state's population, live in a jurisdiction that has adopted the 2018 IECC. As of May 2021, 86% of Colorado's population is on the 2012, 2015 or 2018 IECC. Compared to the 2016 Standards, the 2019 Standards result in an aggregate 10.7% improvement in nonresidential building energy efficiency, further extending the margin of savings for the 2019 Standards compared to Standard 90.1-2016.Ĭolorado is a home-rule state, but under state statute, local jurisdictions are required to adopt one of the three most recent versions of the International Energy Conservation Code at a minimum, upon updating any other building code. This is a greater energy savings than the 7.9% savings that DOE found for the Standard 90.1-2016 over Standard 90.1-2013. DOE that the 2016 Standards exceed ASHRAE/IESNA Standard 90.1-2013 by 13% on average for the nonresidential building types analyzed. In September 2016 the California Energy Commission certified to U.S. The Standards made strong upgrades to LED-based lighting levels, expanded demand response control requirements, and adopted in collaboration with the Office of Statewide Health Planning and Development, the first energy efficiency standards for hospitals, among other changes. The Standards protect indoor air quality through MERV 13 filters (also for low-rise residential) and by continuing significantly higher outdoor air requirements than ASHRAE 62.1. The Standards were officially published by the ICC as the California Energy Code (CEC) on July 1, 2019. In May 2018, the CEC adopted the 2019 Building Energy Efficiency Standards for nonresidential and high-rise residential buildings and hotels, which take effect on Jan.
