RES integrated refurbishment of existing residential buildings to approach sustainable municipal energy system

This paper is addressing the technical advances in building's refurbishment introducing energy efficiency and RES -renewable energy sources. It has been shown hot BPS - Building Performance Simulation can be practically implemented in sustainable buildings design and redesign. The study of New Belgrade buildings block refurbishment by the optimization of building envelope/structure energy efficiency, and PV panels integration in building facade is also presented. Besides, the activities and whole structure of the project proposal for the 'Cost Effective Solar Integrated Refurbishment of whole Residential Buildings in New Belgrade' is presented, including preliminary study results justifying the significance of the proposed project for rational city energy system planning (particularly its district heating/cooling). It could assist in the future city-wide sustainable energy management. Twofold needs of facade/envelope's improvement - thermal and its moisture removal by well ventilated air layer offer solar integrated refurbishment. Concerning the construction works and existing building structure statics, low weight PV cells and PV system's simplicity would make the most appropriate of the solar technologies candidate to be integrated in renewed facade. predmet rada su tehnologije energetske rekonstrukcije zgrada u cilju povećanja njihove energetske efikasnosti i uvođenja korišćenja obnovljivih izvora energije (OIE). Pokazano je kako se simulacije termičkog ponašanja zgrada (STPZ) mogu praktično primenuti pri projektovanju održivih novih zgrada ili rekonstrukcije postojećih. Prikazane su mogućnosti unapređenja energetske efikasnosti stambenih blokova Novog Beograda energetskom optimizacijom omotača i strukture zgrada uz integraciju FN panela. Date su i aktivnosti i predlog cele strukture predloga projekta 'Ekonomično energetsko-arhitektonske rekonstrukcije stambenih blokova Novog Beograda' uključujući i rezultate preliminarnih analiza koji potvrđuju značaj sadržaja projekta koji se predlaže. Za energetike gradova (posebno sisteme daljinskog grejanja/hlađenja) projekat bi mogao da bude osnova razvoja održive komunalne energetike. Dvojna potreba poboljšanja termičkih osobina omotača i odstranjivanje vlage dobro ventiliranim slojem vazduha, pruža mogućnost jednovremenog povećanja energetske efikasnosti i integracije aktivnog korišćenja sunčeve energije, imajući u vidu konstrukcione radove i statiku strukture zgrade. Jaki FN paneli i FN sistem bi mogli biti najprikladnija tehnologija korišćenja sunčeve energije za integraciju sa obnovljenom fasadom.
