The new ISO 18292:2011, “Energy Performance of Fenestration Systems— Calculation Procedure,” is a new standard that enables the energy performance rating of a window, door or skylight, rather than just the thermal transmittance.
It’s based on the effects of the frame, sash, glazing, and shading components combined with building heating/cooling loads and environmental conditions. It is designed to accommodate all climatic conditions – both internal and external – and relevant building characteristics and installation details.
ISO 18292 was created for manufacturers to compare products and to show the energy benefits of new designs or technology, for building officials and others involved in code development and enforcement to determine if products meet local codes, and for homeowners to compare different products and make informed product choices. It has already been adopted for use in Great Britain.
