Saving energy and reducing CO2 emissions in existing buildings

Solar panels

The municipality of Utrecht has ambitious goals for the reduction of CO2 emissions and the achievement of energy savings in existing buildings. HU University of Applied Sciences Utrecht is working with companies to develop a market for private homeowners who want to use zero energy in their homes (making them energy-neutral).


Private homeowners want homes that are free of energy costs. This ambition will only be possible to achieve if supply is developed to meet this demand. The objective of this project is to create a market for private homeowners who want to make their homes energy-neutral.


The first result anticipated by the Reducing CO2 Emissions and Saving Energy in the Existing Buildings project is an increase in the number of existing energy-saving initiatives.

The second result will be supply for the private market at a regional level.

At district level, we are developing pilots and working on the development of a one-stop-shop that private homeowners can use to arrange everything involved.

Collaboration with the construction industry and an industrial approach mean that the large-scale implementation of the 'zero energy' concept is possible, because of which more private homes will be energy-neutral.

We are in discussions with ABN Amro about the creation of extra mortgage facilities for both new-build properties and ‘zero energy’ renovations, given the fact that sustainable renovation significantly increases the value of a property.
