Many reports on green or sustainable buildings focus only on savings levels and disregard the cost of renewable energy production. Some reports focus on building level on‐site renewable energy production optimising storage for passive houses or net‐zero emission buildings. The question is, how far should we go with savings? What is the role of flexible demand or storage at the building level? And to what extent should on‐site renewable energy production be the solution?

Bibliografisk noteHow can the building sector ensure an efficient and affordable energy supply in the future?
Efficient buildings are essential for an affordable Danish energy supply in 2050. This report describes the contribution and role of the building sector in a 100% renewable energy future, as well as the transitions that are necessary in the building sector to support this change.
The report results in a lot of recommendations, for example:
1.Energy savings need to be made in the existing building stock. It is less important to place focus on new buildings to save energy in the future energy system.
2.It is necessary to consider and address connecting technical energy renovations and operation (smart meters) to user behaviour in the building.
3.It is cost‐effective for the energy system to increase the share of district heating from around half of the heat supply today to around two thirds in 2050.
