WHAT WE ASSESS
Heat-loss calculations show how much heat a building loses and where, informing insulation choices and the sizing of heating systems such as heat pumps.
Thermal bridging calculations look at junctions where heat escapes more easily, such as around windows, at floor and roof edges and where insulation stops.
Condensation risk assessments check whether moisture could build up within walls, roofs or floors once insulation is added.
Ventilation assessments look at whether a home will have enough ventilation once it is more airtight.
WHY THEY MATTER
These checks matter most where measures interact, such as internal wall insulation on solid walls, where the wrong detail can lead to condensation and mould.
HOW WE DELIVER IT
Technical assessments form part of our retrofit design and architectural and technical design work, with the scope set by what each design needs.
FREQUENTLY ASKED QUESTIONS
Do I need a heat-loss calculation before installing a heat pump?
A heat-loss calculation is the basis for sizing a heat pump. Our article Understanding heat pumps covers more.
