Abstract

U radu je analizirana troškovno optimalna kombinacija termotehničkih sustava ZEB zgrade s različitim debljinama izolacije vanjskih zidova na području kontinentalne Hrvatske. Promatrana je višestambena zgrada sa 6 nadzemnih etaža, odnosno 5 grijanih sa neto korisnom površinom grijanog prostora Ak = 954,2 m2. Proračuni specifične godišnje potrebne energije za grijanje Q''h,nd i hlađenje Q''c,nd su provedeni prema jednostavnoj satnoj metodi algoritma HRN EN ISO 13790. Analizirane termotehničke sustave čine sustavi s kondenzacijskim kotlovima, protočnim kombinirani bojlerima, kotlovima na biomasu (peleti) te centralnim i lokalnim dizalicama topline zrak – voda za grijanje, odnosno sustav hlađenja čine split klima uređaji, dizalica topline zrak - voda i posredni sustav hlađenja – „chiller“. Osim navedenih, u analizu su se uključili i sustavi mehaničke ventilacije s povratom topline te obnovljivi izvori energije u vidu fotonaponskog i solarnog toplovodnog sustava. Proračun termotehničkih sustava je, uz prethodno navedene, proveden u softverskom paketu KI Expert Pro – program u koji su implementirani svi relevantni algoritmi objavljeni na internet stranicama Ministarstva prostornog uređenja, graditeljstva i državne imovine. Rezultati proračuna su prikazani grafički i numerički, a promatrani su sa stajališta primarne Eprim i isporučene energije Edel, emisija CO2 te udjela obnovljive energije u ukupno isporučenoj RERd. Troškovno optimalna analiza je provedena proračunom globalnog troška sukladno uredbama 244/2012 i 2012/C 115/01. Na kraju, predložena je optimalna kombinacija termotehničkih sustava i debljina izolacije vanjskih zidova.

Abstract (english)

The paper analyzes the cost-optimal combination of HVAC systems for a ZEB building with different external wall insulation thicknesses in the continental region of Croatia. The study focuses on a multi-residential building with six above-ground floors, five of which are heated, with a net usable heated area of Ak = 954.2 m². Calculations of the specific annual energy demand for heating (Q''h,nd) and cooling (Q''c,nd) were made using the simple hourly method based on the HRN EN ISO 13790 algorithm. The analyzed HVAC systems include systems with condensing boilers, instantaneous combi boilers, biomass (pellet) boilers, central and local air-to-water heat pumps for heating, while the cooling systems include split air conditioners, air-to-water heat pumps, and indirect cooling systems ("chillers"). Additionally, mechanical ventilation systems with heat recovery and renewable energy sources, such as photovoltaic and solar thermal systems, were included in the analysis. The calculations of HVAC systems were conducted using the KI Expert Pro software package, which incorporates all relevant algorithms published on the Ministry of Physical Planning, Construction and State Assets website. The results are presented both graphically and numerically, considering primary energy (Eprim), delivered energy (Edel), CO2 emissions and the share of renewable energy in total delivered energy (RERd). The cost-optimal analysis was performed by calculating the global cost in accordance with regulations 244/2012 and 2012/C 115/01. Finally, the optimal combination of HVAC systems and external wall insulation thicknesses was proposed.
