Philadelphia and Pennsylvania Energy Code

Pennsylvania has adopted the 2015 International Energy Conservation Code (IECC) and Philadelphia adopted both the 2015 IECC and 2018 IECC according to project building type. The ReVireo team is dedicated to assisting all Pennsylvania design, development, and construction professionals in the effort to reduce the cost, difficulty, and risk involved with energy code compliance.
