The Dutch government has arranged multiple incentives to stimulate the implementation of Energy Techniques and Measures (ETMs) in the built environment. These ETMs lower the energy use, make use of renewable sources or make use of fossil fuels in a more efficient way. Although the urge is high and the number of available ETMs is large, the rate of implementation is rather low. At the department of CME, research is conducted to gain more insights on how the implementation process of these ETMs takes place and can be improved in such a way that national ambitions can be met.
