A long list of eco-friendly adaptations was laid down during the planning of GlashusEtt. The aim throughout was to achieve a good indoor climate with low energy consumption.

Double-glazed façades and smart-house technology
Double-glazed façades, linked to an advanced control system cuts the energy consumption to 50 % of that of an equivalent building with glass façades. The double-glazed façades reduce the need for artificial light and the energy requirement for heating, cooling and ventilation.

Low-energy lighting has been installed in the entire building. An advanced control system adjusts lighting and ventilation in line with current activities, the amount of daylight, and air quality.

Advanced heating
Heating is primarily provided by a heat pump that takes energy from the pumping station's moist heat and the waste heat generated by the mains power installation.

A fuel cell – an advanced energy converter – have been installed for the first time ever in a commercial building in Sweden. The fuel cell runs on biogas.

The fuel cell
1. Biogas is fed into the fuel cell.

2. Biogas is converted into hydrogen and carbon monoxide.

3. Oxygen is added and electricity is generated.

4. The waste products are carbon dioxide and water.

For a more detailed description of the fuel cell system, please read the PDF-file in the right hand margin.

Solar panels
A solar panel plant has been installed on the roof to supply the building with electricity.

Biogas
A biogas boiler, to meet peaks in heating requirements, and a biogas stove in the kitchenette have been installed. The biogas is produced in the area's own sewage plant and is part of the eco-cycle solution.
