Analizirala sem energetsko učinkovitost stavbe UL FGG na Hajdrihovi ulici 28. Na objektu smo
dvakrat izvedli pregled s termokamero. Iz termografskih posnetkov stavbe sem ugotovila
pomanjkljivosti stavbe, ki s prostim očesom niso bile vidne. Pri ugotavljanju sestave sten sem si
pomagala z opisom predvidenih del v projektu del iz leta 1955. Za kontrolo dejanske sestave sten sem
na štirih karakterističnih mestih zunanjega ovoja stavbe izvedla meritev toplotnega toka s
termočlenom. Na podlagi podatkov o toplotnem toku sem nato izračunala toplotno prehodnost stene,
ki sem jo primerjala s toplotno prehodnostjo dobljeno računsko na podlagi ocenjenih debelin in
karakteristik posameznih plasti materialov. Za linijske toplotne mostove sem izračunala linijsko
toplotno prehodnost s pomočjo programa THERM. Dejanske dimenzije stavbe sem dobila z lasersko
izmero objekta. S programom Gradbena fizika URSA 4.0 sem izdelala računsko energetsko izkaznico
stavbe in dobljene rezultate primerja z merjeno energetsko izkaznico, ki je bila za objekt ţe izdelana.
Ob upoštevanju dejstva, da stavba spada med objekte kulturne dediščine sem predlagala ukrepe za
sanacijo objekta, s katero bi se zmanjšale toplotne izgube in povečala energetska učinkovitost.
Dodatno sem predlagala uporabo obnovljivih virov energije za proizvodnjo potrebne energije za
delovanje stavbe. Ocenila sem stroške izvedbe vseh predlaganih ukrepov. Najučinkovitejši in najbolj
potreben ukrep je toplotna izolacija stropa proti neogrevanemu podstrešju, ki sem ga ocenila na 20
tisoč EUR. Stroški izolacije stropa bi se zaradi privarčevane energije povrnili v 4 letih.

Energy efficiency of building UL FGG at Hajdrihova ulica 28 |
Sekundarni povzetek: |
Energy efficiency of building UL FGG at Hajdrihova ulica 28 has been analysed. Two examinations
with a thermal camera were performed. The thermograms revealed failures in the structure that could
not be noticed visually before. The walls’ structure was obtained from the project description from
year 1955. In order to check the walls’ actual composition, the heat flux was measured with a
thermocouple at four characteristic points of the building envelope. Thermal transmittance was
calculated from the measured heat flux and compared with the thermal transmittance gained through
the estimated thicknesses and physical properties of the walls’ layers. For the longitudinal thermal
bridges, longitudinal thermal transmittance was calculated with a computer program THERM. The
outer and inner dimensions of the building were acquired with a laser measurement. With the program
Gradbena fizika URSA 4.0, an energy performance certificate was prepared and the results were
compared with the results from the energy performance certificate that already existed for the
building. Taking into account that the building belongs to cultural heritage, measures for energysaving
renovation were proposed, which would reduce heath losses and increase energy efficiency. In
addition, measures were proposed for the use of renewable energy resources that would provide the
energy required for the functioning of the building. The costs for the proposed measures were
estimated. The most efficient and also the most required measure is the thermal insulation of the
ceiling toward unheated attic, which was estimated to be 20 thousand EUR. The investment would be
repaid in 4 years time. |
