Hagastaden residentials - Miljöbyggnad
Type: Residential, code compliance, labels and standards (certification)
Client: Einar Mattsson
Summary: Residential building certified according to Swedish green building system Miljöbyggnad, using dedicated IDA ICE extension. Both apartments and systems were modified as a result of the simulation model.
The project involved construction of a large multi-storey residential building in Stockholm, Sweden. The building was to be certified according to the green building system Miljöbyggnad which rates the building in fifteen different aspects (indicators). The system put requirements on for example energy use, heating demand, thermal comfort, max solar load and daylight. Finding, for example, the optimum glazing sizes and types put a major challenge into the project and previous approaches included the use of several softwares, resulting in an extremely time-consuming process.
The apartments and systems of the building were modified based on the result from the simulation model. The requirements for the indicators of Miljöbyggnad were met to ensure occupants health and comfort as well as a low energy use.
Daylight factors are simulated based on the geometry of the IDA ICE model and the Radiance simulation engine
