Energy And Indoor Climate Laboratory
Faculty of Civil Engineering
Department of Environmental Engineering
The laboratory contains special sunlight and diffuse daylight tables that help engineers and architects improve their energy simulation software skills. The Heliodon table is a 1.1m2 square-shaped surface that is used for analysing sunlight indoors at different latitudes, seasons and/or times. In addition to the table the device also contains a projector lamp i.e. a light source and a mirror that reflects the beam of light coming from the lamp onto the model building attached to the sun table.

The test chamber for measuring diffuse light is a cube-shaped box (2.25×2.25×2.25 m). The inner walls of the chamber are covered with mirrors and there is a light-permeable membrane with overhead light sources on top of the chamber. It is possible to determine with simple tests which parameters should a window have in order to ensure diffuse light that conforms to the regulations and how does is it impact the cooling or heating loads of the building and the future energy consumption of the building.
