Building case studies on Swegon Air Academy website! Passive house day care center Trädgårdsstaden in Skövde!

I and my colleague John often visit amazing buildings and we will bring you the interesting facts about some of these buildings.

Already you could read some interesting facts about a passive house day care center Trädgårdsstaden in Skövde with area of 1,607 m² and completed in 2012.

You can also read an annual report (link) on performance of the day care center published by Simone Kreutzer, IG Passivhus Sverige. The report is in Swedish. The evaluation deals with measurements of indoor temperature, indoor air quality, heating use and hot water consumption, and cooling.

The building has demand controlled ventilation system with two air handling units. The air handling unit serving the day care was designed with maximum airflow of 2,200 l/s and the evaluation shows that the unit works at 40% with airflow being between 600 and 1,000 l/s. The demand controlled ventilation is based on temperature control and ppm control (level of 600 ppm). During nights and weekends the ventilation is turned off. And in winter the supply air temperature ranges between 16-18°C during days and approximately 23°C when the air handling unit is switched off. After first year of constant ventilation, the set points were changed to 19-20°C for heating and 23-24°C for cooling. Find more information in the report (link).
