The Ministry of Spatial Planning, Housing and the Environment (VROM) has implemented the EnergyMirror in her headquarters and six regional offices in order to monitor and analyse the energy usage, as well as to carry out energy saving activities. As part of the Improved Energy Performance Program the ministry’s energy management has been expanded with implementation of the Enerlyser in all offices. The Enerlyser allows the energy managers to monitor the energy and water usage of one or multiple buildings through the Internet. Since the Enerlyser is web based, its clear graphs and analyses are available any time any where.
