Together with its Knowledge Sharing platform, this ComAct report provides a basis for training energy advisors. This material intends to allow frontline staff in local municipalities and energy efficiency advisors engaged with the pilot cases of multi-apartment buildings in the ComAct project to master enegy efficiency.

This report is separated into several parts: at the beginning, it provides the basis for a legal and engineering background, where energy pricing is also explained. The following chapters are then divided by measures: simple measures, measures for the building envelope, heating system, preparation of domestic hot water, and for electric energy. For each group, we give both the basics, including the current state and possible improvements of energy efficiency, and more details, where deemed necessary. The level of detail aims to enable participants to fully understand the mentioned advantages and drawbacks of each measure, but without confusing or
oversaturating them with data.

No investment values or payback periods have been calculated and expressed in numbers, since they depend on local circumstances and market prices, and vary from building to building.
