The reduction of the energy demand of a hall-type object through vegetative roof constructions

Abstract

The topic of the energy efficiency of buildings is still relevant, and this article focuses on one form of passively reducing their energy demands, in this case, for a hall-type structure. Hall-type structures are largely horizontal constructions, meaning that their length and width often significantly exceed their height. As a result, a larger cooled surface area of the roof is expected in comparison to the cooled surface area of the facade. While not the sole factor influencing the selection of a structure or balance calculations, it was one of the initial considerations. It is also anticipated that with a larger construction area and its opening structures, there will be a greater area available for covering with a green roof. The coverage of the building's energy facilities occupy a certain percentage of the roof construction area. The work then delves into the energy balances of the given structure under various operational conditions, based on measurements of the thermal-technical improvement of the construction, depending on its composition and coverage with a green structure. The results include balance-based energy savings achieved through the green element, as well as the percentage savings in different operational conditions.
