dc.description.abstractThe comprehensive survey on the sample of 1857 elementary and high schools in Serbia was done during 2016 and 2017. These questionnaires required general data on each institution, as well as answers to 48 questions related to architectural building characteristics and HVAC and electrical systems used. This paper presents the results of the analysis of the gathered answers to sections related to installed HVAC equipment and building characteristics that affect functionality and energy efficiency of HVAC systems. The elaborated questions are related to heating, ventilation, air-conditioning and DHW systems coverage in schools, type of heating system, age of heating system, primary fuel used and the users` satisfaction with the heating system. The correlation between heating system and the users` evaluation of the installed heating, as well as the correlation between the used energy fuel and the users` rating of heating are presented. Different forms of energy and emissions are evaluated: energy needed for heating and DHW, delivered (final) energy, primary energy and CO 2 emission. The results obtained for each typical school building (representative building defined in school typology) in specified construction period (also defined in typology) are expanded to whole school building stock in Serbia. Three different levels of improvements are evaluated. These improvements include increasing of thermal insulation of buildings and interventions on HVAC systems and estimation of possible energy savings.sr
dc.description.abstractObimna anketa sprovedena tokom 2016. i 2017. godine na uzorku od 1857 osnovnih i srednjih škola na teritoriji Republike Srbije obuhvatila je opšte podatke o svakoj instituciji, kao i 48 pitanja o arhitektonskim karakteristikama zgrada i primenjenim sistemima iz domena mašinskih i elektro instalacija. U radu su prikazani rezultati obrade ankete za termotehničke instalacije, kao i za arhitektonske karakteristike koje su bitne za funkcionalnost termotehničkih instalacija i energetsku efikasnost škola. Pored obrade pojedinačnih pitanja u anketi: zastupljenost uređaja za grejanje, ventilaciju, klimatizaciju i pripremu sanitarne tople vode, vrsta sistema za grejanje, starost uređaja za grejanje, korišćeni primarni energent i zadovoljstvo korisnika instalisanim sistemom za grejanje, utvrđena je i korelacija između sistema za grejanje škole i ocene neposrednih korisnika o kvalitetu grejanja, kao i korelacija između dominantno korišćenog energenta i zadovoljstva korisnika grejanjem u školi. Analizirana je potrebna energija za grejanje prostora i pripremu STV, finalna (isporučena) energija, primarna energija i emisija ugljen-dioksida od rada KGH postrojenja. Rezultati dobijeni za svaki tipsku zgradu (prema usvojenoj tipologiji školskih zgrada) i kategorijama po periodu izgradnje škola, prošireni su na celokupni školski fond u Srbiji. Analizirano je 3 nivoa unapređenja zgrada poboljšanjem termičkog omotača školskih zgrada i termotehničkih instalacija u njima uz procenu mogućih energetskih ušteda.sr
