Abstract

The concept of this ``Plus Energy House`` is a building which uses only solar energy for heating purposes and can be used both as a greenhouse (a winter garden) and as office premises at the same time. The design is based on mobile insulation, a bead wall, humidity control and recovery of solar heat with the help of heat pumps. The building incorporates an area of 590 m{sup 2}, and produces surplus energy on an annual basis of ca. 100,000 kWh, which is the amount that four detached houses use for heating annually. A 360 m{sup 2} glass roof with a southerly orientation ensures solar heating of floor, walls and ceilings. The building is heated up within a few hours and, with the help of mobile insulation (polystyrene balls) in the glass roof no more solar energy is needed for two days. The roof is constructed of two layers of hardened glass filled with the polystyrene balls which are blown and sucked backwards and forwards and are used at night to keep in the heat and by day as a means of shading if the rooms become too hot. When the sun shines on the plants, water evaporates and rises  More>>

The roof is constructed of two layers of hardened glass filled with the polystyrene balls which are blown and sucked backwards and forwards and are used at night to keep in the heat and by day as a means of shading if the rooms become too hot. When the sun shines on the plants, water evaporates and rises to the ceiling were it hangs in the form of water drops on the rows of plastic tubes which hang there. These then drop into a channel and are lead away. The water in the tubes circulate to a heat pump which sends the heated water into the heating system and out of the building where it is sold in the form of district heating. Cold and heat storage facilities level the difference between production and need, thus the heat pumps need not be so large. The total area of plant leaves acts as a solar collector. Technical details and diagrams further illustrate this concept. (AB).}
