Heat Loss Form Factor
Elrond Burrell , What is the Heat Loss Form Factor? Blog 03 Aug 2015, states: ‘The Heat Loss Form Factor is one way of measuring the efficiency of the surface area of the thermal envelope. The Heat Loss Form Factor is the ratio of thermal envelope surface area to the treated floor area (TFA). This is effectively the ratio of surface area that can lose heat (the thermal envelope) to the floor area that gets heated (TFA). In other words, the Heat Loss Form Factor is a useful measure of the compactness of a building. And the more compact a building is, the easier it is to be energy efficient. Conversely, the less compact a building is, the more insulation will be required for the building to be energy efficient.’
