A new Swegon Air Academy Case Study is a single family house in Stjørdal i Norway (link to the case study page) with footprint of 165 m2 built as a Future Active House. The house has wooden frame construction with natural ventilation, automatically controlled roof windows and four facade windows, sunscreens preventing overheating on hot days and heat loss in colder times user friendly control of the indoor climate through touch panels, LED lighting, and thick insulation in roof, walls and floor, low-emission wood stove and fire insert contributing to the heating, extensive use of wood, a renewable material and solar collectors of 18,5 m2.
The Active House principles recommend a combination of natural and mechanical ventilation in order to achieve good indoor air quality. However, ventilation and the consequent heating of fresh, cold air can require large amounts of energy. Future Active House seeks to over come this problem by introducing a number of energy-saving technologies. It is possible to allow fresh air to produce an indoor climate that is pleasant and healthy, at the same time as keeping energy loss to a minimum. In the winter, mechanical ventilation will take fresh outdoor air into the house and preheat it in a heat exchanger (using a heat recovery system), thereby reducing the energy required for warming cold air. During summer natural ventilation ensures that the house is cooled and fresh air supplied in a way that significantly reduces the demand for electric fans. Furthermore, openable windows are appreciated by most users in the warm part of the year.
Document about Future Active House Norway (link here) describes vision for future active house, architecture in Nordic, solution as a low energy and high performance building, active house criteria, energy as half the consumption of a normal house, ventilation to stay fresh and keep warm, putting the air work the natural ventilation, control systems as hands on solution, daylight to let the sun inside including daylight factor consideration, materials and products used to build the house, a crucial quality to achieve a healthy indoor climate, flexible simplicity for interior design, black and bright exterior of a building, local solutions for environment qualities, two years of monitoring to confirm the performance and future active house projects.
