Sažetak
This paper shows how new building technologies have to be implemented systematically in order to achieve an in advance proposed standard. For the illustration, a residential and business building in Osijek Croatia is chosen. Although all energy systems and technologies in such buildings are interconnected, the calculation procedure and the manner of using structure elements and technologies which gives energy and economic optimum are analyzed first. To achieve minimal heat energy demand, a new generation of materials are used: energy efficient bricks, vacuum insulated panels, energy efficient windows and solar walls as well as the other state of the art technical solutions. The energy needed for heating and cooling is supplied by geothermal heat pumps with vertical soil heat exchangers (in total 1000m). Solar thermal collectors provide an additional heat source for space heating and warm water preparation. Additionally, the excess solar heat can be stored in a storage tank on seasonal basis. Both heat sources are integrated in an energy system using some additional tanks, pumps and heat exchangers. The distribution of heat energy is warranted through ceiling or floor heating and cooling. Low temperature heating and the ventilation system ensure healthy and high quality living conditions in the building. The building automation connects all technical systems in a whole and takes care of its good functioning.
