Izdelava računske energetske izkaznice dvostanovanjske stavbe in analiza upravičenosti priporočil za energetsko sanacijo : diplomska naloga

Tehovnik, Domen (author), Košir, Mitja (mentor)

V diplomski nalogi je predstavljena izdelava računske energetske izkaznice s poudarkom na priporočilih za energetsko sanacijo dvostanovanjske stavbe, locirane v Medvodah. Stavba je bila zgrajena leta 1985. V tem obdobju se je začela uporabljati toplotna izolacija, saj so se že pojavljala vprašanja o energetski učinkovitosti stavb. Energetska izkaznica stavb je potrebna pri prodaji in najemu stavbe, če je obdobje najema daljše od enega leta. Obvezna je tudi pri novogradnji kot del projekta izvedenih del. V uvodnem delu sem predstavil veljavno zakonodajo, ki ureja področje učinkovite rabe energije v stavbah. Potem sem s pomočjo programa TEDI in TOST izdelal računsko energetsko izkaznico za obravnavani objekt v obstoječem stanju, nato pa sem se osredotočil na učinkovitost posameznega ukrepa energetske sanacije. Pri vsakem ukrepu sem komentiral dobljene rezultate in se odločil o smiselnosti njegove izvedbe v odvisnosti od tehnične zahtevnosti in posledičnega prihranka energije. Pri obravnavani stavbi se največ energije, potrebne za ogrevanje z menjavo transparentnega dela in mehanskim prezračevanjem, prihrani z vračanjem toplote odpadnega zraka, in sicer blizu 50 %. Z izborom vseh ukrepov, za katere menim, da so smiselni, pa se prihrani preko 80 % potrebne letne toplote za ogrevanje stavbe. Tudi koeficient specifičnih transmisijskih izgub se zmanjša za 60 %. Poveča pa se potreba po hlajenju, kar je tipična stranska škoda zelo dobro toplotno izoliranih stavb. V zaključnem delu so predstavljene ugotovitve, nastale tekom diplomske naloge.

• Title: Calculated energy performance certificate of a duplex house and energy renovation analysis

Abstract

In the undergraduate thesis, the production of the calculated energy performance certificate for the specific building is undertaken. This is done with the emphasis on recommendations for energy renovation of the duplex residential building, which is located in Medvode, Slovenia and was built in 1985. When the building was constructed, energy efficiency was already gaining importance. Consequently many buildings constructed in this period were moderately thermally insulated. An energy performance certificate is legally required when a building is offered for purchase and when it is leased for a period longer than one year. Furthermore the certificate is mandatory for newly built properties, as a basic requirement for the project plan. The thesis initially examines the current legislation, which regulates the area of energy efficiency in buildings. Next the energy performance for the considered building will be produced. This will be done with TEDI and TOST computer software. After that, individual technical measures will be analysed. The viability of these measures will be assessed in consideration of technical complexity and estimated energy savings potential. For the considered building, the greatest energy savings can be realised with exterior joinery renovation and installation of heat recovery ventilation. The implementation of booth measures accounts for about 50% of energy savings. With the comprehensive renovation, more than 80% of the annual heat required for the building would be preserved. In this case the specific heat transfer coefficient would decrease by about 60 %. On the contrary the requirements for cooling would increase, which is the common downside of a well-insulated building.
