There is a new online research portal that summarises some of the long-time funding measures of the German Federal Ministry of Economics and Technology (BMWi) under one umbrella: energy-optimised construction (EnOB), energy-efficient city (EnEff:Stadt) and energy-efficient heating and cooling networks (EnEff:Wärme) as well as research regarding thermal energy storage and low-temperature solar thermal systems.
The website www.projektinfos.energiewendebauen.de presents examples of projects and activities that apply technologies such as phase change materials for optimising the energy needs of buildings.
