Great to get energy in use update for 2022 usage from some clients as the New Year arrived – their total gas used was 2000Kwh . For a treated floor area of 133 sq.m that’s achieved 15 Kwh / m2.a ….actually Passivhaus target. The design didn’t quite aim for PH certification due to budget etc. Design heat demand was 22 Kwh/m2.a so that’s a great result ! Has cost £21/mth for gas.
