WHEN someone asks what a house will COST TO RUN, what it costs the climate, or whether it will overheat in summer. From the CAO scene: the heating need by the degree-day method (envelope and ventilation heat-loss coefficients, solar gains per orientation corrected by shading factors MEASURED on the scene's own sun paths, internal gains, and the EN ISO 13790 gain-utilisation factor), domestic hot water, and the resulting consumption in final and primary energy for the chosen generator; an order-of-magnitude embodied carbon figure (Ic construction) from the bill of quantities times YOUR emission factors; and a summer check comparing August solar gains against what one night of ventilation can remove. Climate data (degree-days, irradiation) and carbon factors come from the caller — nothing is guessed. This is NOT a French DPE nor the regulatory RE 2020 calculation.
