The brief
UK Building Compliance carried out L1B SAP calculations on a barn conversion to a holiday unit.

The results
- Compliant on L1B regulations.
- Guidance was given on gaining higher EPC scores through heating systems and the use of renewable technologies.
- Dwelling emission rate of just 0.65 kgCO₂/m² against a target of 17.61 — a significant compliance margin driven by renewable heating choices.
