Indirektna zelena fasada kao mjera za sprečavanje pregrijavanja

Lesjak, Valentina (author), Pajek, Luka (author), Košir, Mitja (author)

U radu je prikazana simulacija i eksperimentalno istraživanje utjecaja indirektne zelene fasade (IZF) na toplinsko ponašanje zgrade. Istraživanje je provedeno na lokaciji Punat na otoku Krku u Hrvatskoj tijekom ljeta 2018. godine. Primjenom IZF-a utjecaj sunčevog zračenja smanjen je do 505 W/m2 , a temperature na vanjskoj površini fasade smanjene su do 13,5 K. Eksperimentalni su rezultati korišteni za simuliranje toplinske ugodnosti u unutrašnjosti zgrade primjenom jednostavnog modela. Kada je IZF postavljen preko čitavog zida izloženog suncu, prosječno smanjenje operativne temperature iznosilo je do 6 K za novu zgradu, tj. do 5 K za tradicionalnu kamenu kuću.

Abstract

Simulation and experimental investigation of the indirect green façade (IGF) impact on thermal behaviour of buildings is presented in the paper. The study was conducted in Punat, Krk, Croatia, in the summer of 2018. The IGF reduced the incident solar radiation by up to 505 W/m2 and façade temperatures by up to 13.5 K. Experimental results were used to simulate the indoor thermal comfort of a simple building model. When IGF was positioned across the entire sun-exposed wall, an average decrease of operative temperature was up to 6 K for a new house and up to 5 K for a traditional stone house.
