Fenestration affects building energy use through four basic mechanisms: thermal heat transfer, solar heat gain, visible transmittance and air leakage. Condensation resistance is considered not to affect energy use and is therefore not a concern of the building codes. However, CRF is an important thermal performance characteristic and is therefore included in this document.
