Accurate and reliable measurement of whole building fabric heat loss (also known as a heat transfer coefficient or HTC) is considered by many to be the holy grail in building performance measurement and understanding. 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.
With over 10 years experience in measuring whole building heat transfer coefficients using conventional co-heating methods, the team at BTS are working closely with the University of Salford and others to develop and refine a game changing in-situ HTC algorithm. Our approach allows for a measurement to be taken in an entirely passive manner through the combination of internal and external temperature sensor data alongside gas and electricity consumption data arising from smart meters.
Our Smart HTC solution is currently under development and undergoing extensive testing and evaluation. The BTS team are however always on the lookout for parties interested in participating in our trials or exploring early stage options for integration. A full commercial product is expected in 2020.
