The purpose of this regulation is to improve the energy efficiency of manufactured fenestration products for all new and existing buildings. These products are a key component of a building’s exterior envelope that affects the energy usage required to heat and/or cool the conditioned space. Improved energy efficiency can reduce energy cost for homeowners and businesses and reduce greenhouse gas emissions.
This circular includes updates to the Energy Efficiency Standards Regulation (EESR) for windows, glazing, doors and skylights that were approved March 6, 2018.
