Multifunctional roof covering and structures

Abstract

Modern architectural concepts, which are based on rational energy consumption of buildings and the use of solar energy as a renewable energy source, give the new and significant role to the roofs that become multifunctional structures. Various energy efficient roof structures and elements, beside the role of protection, provide thermal and electric energy supply, natural ventilation and cooling of a building, natural lighting of the indoor space, sunbeam protection, water supply for technical use. There are numerous possibilities to achieve the new and attractive roof design which broadens to the whole construction. With such inducement, this paper principally analyze the roof integrated solar thermal collectors and photovoltaic modules, as well as the visual effects that may be achieved by their application.

Savremeni arhitektonski koncepti zasnovani na racionalnoj energetskoj potrošnji zgrada i upotrebi sunčeve energije, kao obnovljivog izvora energije, daju nove i značajne uloge krovovima, koji postaju multifunkcionalne strukture. Različite energetski-efikasne krovne strukture i elementi, osim zaštite, omogućavaju snabdevanje toplotnom i električnom energijom, prirodnu ventilaciju i hlađenje zgrade, prirodno osvetljavanje prostora, zaštitu od sunčevih zraka, snabdevanje tehničkom vodom. Raznovrsne su mogućnosti za nov i atraktivan dizajn krovova, a time i objekata. To je povod da se u radu analiziraju toplotni prijemnici sunčeve energije i fotoelektrični moduli integrisani u krovne ravni, sa akcentom na vizuelne efekte koji se njima postižu.
