This invention relates to a method and apparatus for energy effective regulation of temperature and ventilation of one or more ventilation units of buildings, where one or more heat-pumps are used to exchange thermal energy between outdoor air and an indoor heat carrying fluid medium and where the heating and/or cooling of each ventilation units are achieved by distributing the indoor heat carrying fluid medium in each ventilation units, in such a manner that the natural short term variations in outdoor temperature due to passages of weather systems and the day/night variations is utilized to give the one or more heat-pumps optimized conditions such that they are only turned on for extracting outdoor heat which is delivered to the indoor heat carrying and distributing fluid medium at the relative warm periods in the case of warming the buildings, or only in the relative cold periods for cooling the heat carrying and distributing fluid medium for removal of indoor heat in the case of cooling the buildings, and that the thermal energy that is exchanged with the outdoor air is partly used to cover the ventilation units actual demand for heading or cooling while the remaining major part of the thermal energy is sent to a thermal store to cover the ventilation units heating or cooling demand during the subsequent periods where the natural weather conditions is less favorable for exchanging thermal energy from outdoor air by use of heat-pumps.
