This International Standard specifies a procedure for calculation of the energy performance of fenestration
systems used in residential buildings, for rating of fenestration systems, doors and skylights, including the
effects of frame, sash, glazing, and shading components. This International Standard specifies procedures for
the calculation of the heating and cooling energy use in residential buildings, internal and external climatic
conditions, and relevant building characteristics.
These procedures can accommodate all climatic conditions and installation details. It is the responsibility of
the appropriate regulatory authority to identify the clauses of this International Standard to be applied in their
area of jurisdiction and the climatic data and reference building specification(s) to be used.
