Apstrakt

U Evropi postoji oko 6,2 milijardi m2 korisne površine u nestambenim zgradama koje troši 141.2 Mtoe, što iznosi 13.3% ukupne finalne potrošnje energije. Sektor nestambenih zgrada je složeniji i heterogeniji od sektora stambenih zgrada, te su zbog toga vrlo ograničene dostupne infromacije o fondu nestambenih zgrada, nedostaju konkretni podaci o površini zgrada, karakteristikama konstrukcije i analizama korišćenja energije za različite sisteme. Nacionalne studije i evropski pregledi ukazuju na ovaj jaz u poznavanju i dostupnosti sveobuhvatnih podataka koji ometa napore da se prate energetske karakteristike nestambenih zgrada, da se izrade odgovarajuće baze podataka i omogući modeliranje zgradarskog fonda.U prvom delu rada je prikazan pregled raspoloživih informacija i relevantnih pokazatelja u javno dostupnim bazama podataka u Evropi (npr. Eurostat, EU observatorija zgradarskog fonda, Odysee-Mure) i u SAD (npr. CBECS, ASHRAE). U drugom delu je dat pregled izračunatih intenziteta potrošnje energije za nestambene zgrade u Grčkoj, na osnovu podataka iz sertifikata o energetskim karakteristikama. Raspoloživi podaci su grupisani i analizirani za trideset namena zgrada, različite periode izgradnje i klimatske zone, kako bi bili izvedeni razni reperi ili standardi za merenje energije (benčmark). U skladu sa tim, prosečan intenzitet korišćenja primarne energije iznosi 513.4 kWh/m2, a emisije iznose 160.7 kgCO2/m2. Unutrašnje sportske dvorane i bazeni su objekti sa najvećim intenzitetom korišćenja energije, dok škole koriste najmanje energije, zbog rasporeda njihovog rada. Osvetljenje je sistem koji troši najviše energije, a slede hlađenje, grejanje prostora i vrlo malo korišćenje energije za grejanje sanitarne tople vode.
