The provision of heating and cooling in a building is highly energy intensive. This can partly be tackled through more efficient conversion of energy to heat or cooling, better controls and building occupant awareness but by far the biggest fundamental influencing factor is the performance and overall integrity of the building fabric insulation layer.
Taking account of variability in weather, solar effects, occupancy behaviours and the efficacy of building services in order to derive true building fabric performance is however a highly complex challenge. This has led to a heavy reliance on models and simulations or worse, the use of basic calculations or assumptions based on design specifications or basic on-site visual inspections.
BTS are working with a number of leading experts to develop a range of in-situ measurement methods that will allow the fabric thermal performance of a building to be directly measured and quantified.
