Look up the code

look up the energy code

Each state references or develops a building energy code using national energy codes such as ASHRAE 90.1 and the International Energy Conservation Code (IECC).  To determine which code your state references, click on your state to read the residential and commercial energy code required.  Once the code is identified, you may obtain the code from local authorities, purchase it online, or contact IECC and ASHRAE to purchase.

You can look up the energy code online. The Online Code Environment & Advocacy Network (OCEAN) is a great place to start.

Most energy codes require NFRC ratings or direct manufacturers to use punitive default values found in the relevant energy code.  If the window products you are inspecting have no rating, you may assign it the default value based on your state’s energy code default. Details...
