Smart HTC

Smart HTC delivers an accurate and reliable measurement of whole building fabric heat loss (also known as a Heat Transfer Coefficient or HTC). 

The measurement takes into account the performance of the building fabric as a whole and within a single value, indicates the amount of energy required to maintain a building at a stated temperature. HTC is calculated ‘under the bonnet’ in every single SAP & RdSAP assessment and also enables direct comparison of predicted and measured performance.
