Minimising the heat loss from a building’s non-linear junctions will have a significant impact on reducing a building’s overall heating demand. Thermal Bridge Calculations therefore are becoming a critical component in the energy modelling undertaken for Building Regulations and compliance with the Target Fabric Energy Efficiency (TFEE).  Accurate psi values are also necessary on many schemes in order to achieve the Zero Carbon Hub and Passivhaus standards.

SRE can undertake detailed Thermal Bridge Calculations (using Psi-therm software) to determine specific psi values for all standard and non-standard junctions. As required by Building Regulations the psi values can be signed off by a competent person and used within the SAP and SBEM software.
