LOW ENERGY LOW TEMPERATURE TOWN HEATING PLANT

Ziel

The project comprises a low energy building development with 52 terrace houses and 19 bungalows situated in Skive.
The aim of the project is to demonstrate to what extent the building trade today can put the results of energy research into practise in a large low energy building development, thereby contributing towards a quick incorporation of the newest energy technology in future residential building.
A further objective is to demonstrate how a resource saving development plan can incorporate both a good outdoor environment and possibilities of exploiting passive solar heating. Finally, it is intended to demonstrate the use of low temperature district heating with a "summer stop".
Skive 84 Low Energy building development is the result of a building competition which aimed at reducing the energy used for room and domestic hot water (DHW) heating by 40 % in relation to the energy guidelines in the present building legislation (BR 82).
1. A few problems occured with DHW plants in 3 houses:
(i) in the 2 houses where the DHW plants are directly connected with the low temperature district heating network, DHW is not hot enough;
(ii) in one of the houses where the DHW plant is composed with a small air/water heat pump and an (auxiliary) electric cartridge, the heat pump did not operate properly, thus leading to an excessive electricity consumption.
2. The energy savings achieved in the whole Skive 84 estate amount to 370 MWh/year; this is equal to approximately 40 % of the energy consumption in houses constructed according to the BR 82 building code, with normal district heating or detached houses heated traditionally by oil.
The project includes the following points :
1. Construction principles which incorporate the use of highly effective insulation which gives heat tight houses.
2. Ventilation of the heat tight houses, including the use of heat re-cycling.
3. Simple heating systems operating with a low temperature of 60/40 C.
4. Development plan which takes into consideration the greatest possible utilisation of passive solar heating, shade conditions and the resources used for the district heating, roading and sewage networks.
5. Low temperature district heating with "summer stop" to reduce heat loss in pipes. During the summer period (1 May to 1 October) water heating is decentralized with individual households using solar heaters, heat pumps or electric cartridges.
6. Houses are ventilated by a heat re-cycling system based on a balanced air exchange. During the summer period, when the district heating system is not operating, heating requirements can be covered by an electronic heating elementin the ventilation system.
7. All radiators are fitted with thermostats which immediately compensate for sunshine and other types of free heat.
