Door energy rating DER
Door Energy Rating schemes are based on a traffic-light style A-G ratings system for energy efficiency similar to the labelling system used for fridges, washing machines, cookers and so on. An A rating indicates a good level of energy efficiency, whilst G is the lowest rating. Low rated doors will not normally satisfy building regulations requirements.
The British Fenestration Rating Council (BFRC) operates a Door Energy Rating Scheme. BFRC is a wholly-owned subsidiary of the glazing industry’s trade association, the Glass and Glazing Federation. BFRC also operates a Window Energy Rating (WER) scheme. They launched the Door Energy Ratings Scheme in September 2011.
The rating includes consideration of U-value and air infiltration. Solar gain is not included in the rating process for external ‘pedestrian doors’. However ratings for doors with a glazed area of 60% or more do include solar heat gain (g-value). This is the same rating method that is used for Window Energy Rating.
