International Energy Conservation Code
The 2009 International Energy Conservation Code, adopted into law under the Pennsylvania Uniform Construction Code. Sets minimum energy-efficiency requirements for buildings.
International Energy Conservation Code (2009)
Pennsylvania's Uniform Construction Code adopts the International Energy Conservation Code by reference; the 2009 IECC was the edition in force during its adoption period. It establishes energy-efficiency requirements for the building envelope, mechanical systems, lighting, and service water heating for both residential and commercial buildings.
