a) Buildings that are actively heated to less than 10 °C, excluding cold storage rooms;

b) Cold storage rooms that are not actively cooled to below 8 °C;

c) Buildings whose construction permit is limited to a maximum of 3 years (provisional buildings).

2. Conversions are exempt from the requirements for winter thermal insulation of the building envelope pursuant to § 8 EnVSO, if they do not involve an increase or decrease in indoor air temperatures and thus no higher temperature difference is created in the thermal building envelope.

3. Exempt from the requirements for summer thermal insulation of the building envelope pursuant to § 9 EnVSO are

a) Buildings whose construction permit is limited to a maximum of 3 years (provisional buildings);

b) Conversions, if they do not result in any rooms newly falling under § 9 EnVSO;
