Building Energy Code for the District of Columbia


NOTE: Much of the information presented in this summary is drawn from the U.S. Department of Energy’s (DOE) Building Energy Codes Program and the Building Codes Assistance Project (BCAP). For more detailed information about building energy codes, visit the DOE and BCAP websites.

The DC Energy Conservation Code is updated regularly as national codes are revised or if a change is proposed by local code enforcement officials, industry, design professionals, or other interested parties. Proposals are initiated by the District of Columbia Building Code Advisory Committee.

Interconnection Standards


In July 2006 the District of Columbia Public Service Commission (PSC) initiated a formal inquiry into the development of uniform interconnection procedures for on-site distributed generation systems. The PSC subsequently concluded that an interconnection standard was feasible and continued with the rule making process, culminating with the adoption of final interconnection regulations in February 2009 (DC PSC Order No. 15182). The rules apply to all distributed generation systems of 10 megawatts (MW) or smaller that are operated in parallel with the electric distribution system and are not

Property Assessed Clean Energy Financing


Note: In 2010, the Federal Housing Finance Agency (FHFA), which has authority over mortgage underwriters Fannie Mae and Freddie Mac, directed these enterprises against purchasing mortgages of homes with a PACE lien due to its senior status above a mortgage. Most residential PACE activity subsided following this directive; however, some residential PACE programs are now operating with loan loss reserve funds, appropriate disclosures, or other protections meant to address FHFA's concerns. Commercial PACE programs were not directly affected by FHFA’s actions, as Fannie Mae and Freddie Mac do

Solar Energy System and Cogeneration System Personal Property Tax Credit


The District of Columbia Council created a personal property tax exemption for solar energy systems and cogeneration systems within the District by enacting B19-0749 in December of 2012.

Eligible solar systems Solar energy is defined by D.C. Code § 34-1431 to mean "radiant energy, direct, diffuse, or reflected, received from the sun at wavelengths suitable for conversion into thermal, chemical, or electrical energy, that is collected, generated, or stored for use at a later time". This seemingly broad definition can include solar photovoltaics (PV), solar thermal, or any other energy

Solar Renewable Energy Credits


 In January 2005, the District of Columbia (D.C.) Council enacted a Renewable Portfolio Standard (RPS) with a solar carve-out that applies to all retail electricity sales in the District. In October 2008 the RPS was amended by the Clean and Affordable Energy Act (CAEA) of 2008. Significantly, this legislation increased the percentage and number of benchmarks that utilities must meet, included solar water heating as an eligible technology, increased the alternative compliance payment and amended reporting requirements. The solar requirements began in 2007 at 0.005% of retail electricity sales

Sustainable Energy Trust Fund


The District of Columbia's Retail Electric Competition and Consumer Protection Act of 1999 required the DC Public Service Commission (PSC) to establish a public benefits fund to provide energy assistance to low-income residents, and to support energy-efficiency programs and renewable-energy programs. This fund, known as the Reliable Energy Trust Fund (RETF), took effect in 2001. In October 2008, the District of Columbia enacted the Clean and Affordable Energy Act (CAEA), which effectively eliminated the RETF and replaced it with the Sustainable Energy Trust Fund (SETF). This program will be
