- High investments for building owners required.
- Skills and know-how in the executing trade is not widespread yet.
- Split incentives (user-investor dilemma).
- Mandatory Energy performance certificate (EPC) for building owners.
- Passive house will be standard for buildings in future according to the energy concept of the Federal Government.

Buildings are resource-intensive. Up to 40% of the total final energy consumption are caused by the operation of buildings in Germany. New technologies can help to realise energy savings of up to 80%. The functional and aesthetic building integration will play a major role in the future.
Future building materials and facade systems could be multi-functional: innovative glazing and thermal insulation systems protect from heat and cold, absorb sound, produce and save solar energy and control supply of daylight and fresh air - all at the same time. New technologies like adaptive facades, vacuum insulated panels (VIP), phase change materials (PCM) and building-integrated photovoltaics (BIPV) save costs, preserve resources and open up innovative fields in architectural design (Association for Transparent Insulation - FVTWD e.V.).
