Energy consumption of non-retrofitted institutional building stock in Luxembourg and the potential for a cost-efficient retrofit

As a result, the type of buildings with the highest potential for retrofit measures was identified. Schools, offices and accommodation facilities with a “high” consumption of more than 190 kWh/(m2a) show the highest economic potential with retrofit costs of 0.04-0.08 €/kWh if their energy consumption is lowered to values of around 90-100 kWh. Other groups of buildings show higher costs of around 0.07-0.19 €/kWh.
