Heat Loss Calculations
Room-by-room or zone heat loss calculations to size heating systems correctly after fabric upgrades and ventilation changes.
Heat loss calculations that reflect post-retrofit fabric performance—avoiding oversized plant and supporting low-carbon heat design.
- Aligned to upgraded U-values and infiltration assumptions
- Supports emitter and heat pump sizing dialogue
- Documentation for regulator and manufacturer checks where required
