Hourly TMYx (2009–2023) climate data is split into 1 °C bins; in each bin the building load is met with capacity and COP/EER derived from the product's Eurovent part-load points. Hours outside the operating schedule count as standby consumption; with after-hours setback heating selected, low-load heating is also computed in those hours whenever the outdoor air drops below the threshold.
