Information

The energy report for both buildings in Hagen can be accessed directly from the www.hagen.de web-site. The public service can also be accessed directly via envi-do.dynaccess.de.

 

The pilot site Hagen (Germany) assess Energy Management and Energy Decision Support SMARTSPACES services for viability in several buildings.

The two partners, City of Hagen (GWH) and envi developed a concept for metering, so that the efficiency of the installed technology (for example heat pipes) and the consumptions of heat for different use areas in the buildings can be evaluated.

Meters visualise all data through a web portal so that they can be presented for different purposes and users. For example, there will be a public space where employees can see the development of the heat consumption and will be motivated to participate in energy saving activities.

The specific energy consumption of similar areas can be compared. User groups with low energy consumption can be identified and serve as an example for good practice. The reasons for the differences in energy consumption between different types of users are elaborated and published.

In a password protected area it is possible for the employees to fill in a time schedule for the use of energy in different areas of the buildings. This time schedule is used automatically for room conditioning.

A periodic comparison of energy input and energy output makes a permanent observation of the technical operating efficiency of the energy systems possible. Malfunctions or energy consumption which are above a calculated or measured threshold are immediately detected and resolved without delay.
