City-zen’s projects

		Residential retrofit in Amsterdam High level retrofit of residential buildings in Amsterdam to reduce their net energy use. More info
		Retrofitting towards zero energy buildings in Grenoble The city will focus on existing dwellings with the objective to reach the level of current thermal regulation for new buildings : BBC renovation level.
