Heating Energy Consumption and Cost Allocation in Multi-Storey House

Tema ovog rada je raspodjela potrošnje i troškova toplinske energije za višestambenu zgradu. Promatrana zgrada je izgrađena je prije 44 godine u Zlatar Bistrici i ima 20 stanova. Za svaki su stan izračunati toplinski gubici prema HRN EN ISO 13790 te isporučena energija prema HRN EN 15316-2-3:2008 i HRN EN 15316-4-1:2008. Usporedbe rezultata sa stvarnim vrijednostima pokazuju da se troši više energije nego što bi se to proračunski trebalo. Troškovi za grijanje dijele se prema udjelu površine stanova što je nepravedno jer se ne dovodi do svakog stana ista količina energije. Zbog vertikalnog razvoda ne možemo točno odrediti količinu isporučene energije za pojedini stan. Razdjelnici topline olakšali bi raspodjelu troškova, no i oni imaju određene mane koje bi se mogle kompenzirati odabirom određenog modela raspodjele troškova. U radu su objašnjena tri modela naplate, a na stanarima je da ako žele pravedniju raspodjelu troškova odaberu onaj koji im se najviše sviđa ili smisle neki novi.The topic of this paper is distribution of heating energy consumption and cost allocation in multi family building. This building was build 44 years ago in Zlatar Bistrica and have 20 apartments. For each apartment, heat losses were calculated according to HRN EN ISO 13790 and supplied energy according to HRN EN 15316-2-3:2008 and HRN EN 15316-4-1:2008. Comparisons of the results with actual values shows that more energy is consumed than it was calculated. Heat cost are calculated according to the floor area of each apartment which is unfair because the same amounth of energy is not supplied to each apartment. Due to vertical pipeline network, we cannot accurately determine the amount of energy delivered to a particular dwelling. Heat cost allocators would facilitate cost allocation, but they also have certain disadvantages that can be compensated by choosing a specific cost allocation model. The paper offer three models and it is up on tenants to choose the one they like best or come up with new one if they want a more equally costs distribution
