Hello,
the energy saving ordinance verification is a good first approximation for the required capacity. The energy saving ordinance verification was certainly prepared by a specialist planner and not by the architect. I would start there and ask the architect to arrange a joint appointment with this person. It may be that the "standard" of the energy saving ordinance verification was simply scaled down without involving you as users. Currently, this can still be done and a heat load calculation as described by BeHaElja can also be carried out. General assumptions are extremely difficult because user behavior, location, building structure, and the building physics package all play a role. Basically, the specialist planner should run through several variants to select the appropriate building physics package and the suitable energy generator (air-to-water heat pump, ground-to-water heat pump, gas condensing boiler, combined heat and power plant, etc.) taking into account the legal requirements and your wishes!
Best regards, Erik
