  "text": "The heat loss of the building shall be calculated in accordance with national practice or using a suitable validated computer program based on EN 832, the Euronorm for calculating heat loss. This heat loss should then be compared with the current values required by building codes. For existing buildings, it is generally cost effective to bring the insulation standard closer to current values before sizing the heat pump for the reduced heat loss.",
