Does my building need to comply with the energy code if it will not be cooled or heated?


In the 2015 IECC, Section C402.1.1 Low-energy buildings – low energy buildings or portions separated from the remainder of the building by a building thermal envelope complying with the code, can be exempt from the building thermal envelope provisions of Section C402 if:

  1. Has a peak design rate of energy usage less than 3.4 Btu/h * ft2 or 1.0 watt/ft2 of floor area for space conditioning purposes
  2. Those that do not contain conditioned space
  3. Greenhouses
