Apstrakt
U radu se predlaže optimizacija korišćenja sunčeve energije u energetski efikasnim stambenim zgradama u Japanu. Da bi se projektovao racionalni sistem korišćenja sunčeve energije, treba tačno odrediti strukturu energetske potrošnje u stambenoj zgradi i klimatske uslove regiona. Prema statističkim podacima, u stambenim objekitma u Japanu tri su glavna dela potrošnje energije: toplotna energija za grejanje, za zagrevanje potrošne vode i električna energija za kućne aparate, uključujući osvetljenje i kuvanje. Zbog toga je predložena i simulacijama proverena sledeća strategija: termička izolacija omotača zgrade radi smanjenja potreba za grejanjem; postavljanje sistema za sunčano zagrevanje sanitarne vode i postavljanje fotonaponskog sistema za smanjenje potrošnje električne energije iz mreže. Sprovedene simulaeije pokazuju da se dobrom kombinacijom toplotnih PSE i FN prijemnika, sunčevom energijom može racionalno supstituisati 50% potrošnje
energije u prosečnoj japanskoj kući.
