Abstract
A method of air-conditioning a building with low heat loss, having the following steps: providing a fresh-air/outgoing-air system for feeding fresh air through a heat accumulator being located beneath said building and extracting said outgoing air through the heat accumulator; routing the fresh-air and the outgoing air in first and second tubes, where the first tubes are nested in the second tubes so as to recover heat energy present in the outgoing air.
Claims4
Low-energy house having the following features:
- a solar absorber accommodated on or beneath the roof;
- a heat accumulator arranged beneath or laterally alongside the building;
- fluid-channeling devices including connecting lines between the solar absorber and the heat accumulator;
- exterior walls of the building with an outer insulating layer, an inner insulating layer and with a core zone, which is designed as a load-bearing concrete wall;
- the fluid channelling devices also including fluid lines which are arranged in the core zone and are connected to the solar absorber and the heat accumulator.
