The basis of every structured building renovation at the Kika/Leiner Group is an energy certificate. This is the type certificate of the building, so to speak, and provides information about the key energy figures of a property.

In order to sustainably reduce energy consumption, we calculate energy certificates for Kika and Leiner buildings with a total area of ​​over 1 million square meters. On this basis, we also develop renovation options for all buildings.
