The Energy Code for Maryland was established under the Energy Conservation Building Standards Act enacted by the Public Service Commission. The adoption of the Energy Code now takes place under the Maryland Building Performance Standards (MBPS).
The State of Maryland has adopted with modifications, the International Building Code (IBC) 2015 and the International Residential Code (IRC) 2015 as the Maryland Building Performance Standards ("Standards"). These standards required the buildings to be designed and constructed in accordance with the International Energy Conservation Code (IECC) 2015.
Local jurisdictions may not modify this standard to a lesser requirement.
