diplomska naloga
Abstract
Ker je energetska učinkovitost stavb danes upravičeno zelo aktualna tema, sem v diplomski
nalogi za manjši večstanovanjski objekt preučila možnosti energetske sanacije le-tega in
vpliv možnih sanacijskih ukrepov na dnevno osvetljenost v izbranih prostorih. Preverila sem
tudi do kakšnih razlik prihaja, če želim s stavbnim toplotnim ovojem zagotoviti različne
stopnje izolativnosti. Uporabila sem pet izolacijskih materialov z različno toplotno
prevodnostjo in štiri tipe oknen, ki se med seboj razlikujejo glede na tip zasteklitve in material
okvira.
Ugotovila sem, da je z letno potrebno toploto za ogrevanje stavbe zelo težko ugoditi
zakonskim zahtevam ter da na količino dnevne svetlobe v prostorih najbolj vpliva debelina
dodatne toplotne izolacije in transparentnost stekla τv. Z obravnavanimi kombinacijami
sanacijskih ukrepov lahko količino dnevne svetlobe v referenčnih prostorih zmanjšam za
5,7% do 37,9%.
Presenetljivo je, da večina proizvajalcev oken svoje izdelke oglašuje le z vrednostjo toplotne
prevodnosti U, o faktorju τv pa laičnim strankam ostane zamolčano.

Secondary title: |
Energy retrofit of small multi-family building and its influence on daylighting |
Secondary abstract: |
The energy efficiency of buildings is a very current topic, so in my graduation thesis, I
decided to analyze the potencial for energy retrofit of a small multi-family building and also
how to provide more daylight in the spaces. I checked the differences between different
levels of insulation, provided by building’s thermal envelope. I used five thermal insulation
products with different thermal resistence and four windows with different glass type and
frame material.
I discovered that it is almost impossible to achieve the law requirements with the annual
needed energy to heat up a building and that the amount of daylight in spaces depends on
the thickness of extra thermal insulation and transparency of the window glass τv. With the
used combinations of retrofit measures, I can reduce the amount of daylight in referential
spaces from 5,7% to 37,9%.
It is surprising to see that the majority of window manufacturers promote their products only
with the information of the heat transfer coefficient U but the buyer gets almost no
information about the factor τv. |
