Energetska prenova prizidka Osnovne šole Loka v skoraj nič-energijsko stavbo : diplomska naloga

Jerman, Urška (author), Košir, Mitja (mentor)

V svojem diplomskem delu sem izvedla energetsko prenovo prizidka Osnovne šole Loka Črnomelj. V Sloveniji je Pravilnik o učinkoviti rabi energije v stavbah (PURES 2010) trenutno osnovni zakonodajni dokument, ki regulira področje energetske učinkovitosti stavb, tako za novogradnje kot tudi za prenove obstoječih stavb. V skladu z njegovimi zahtevami so osnovani izračuni v računalniškem programu TOST, s katerim sem preverjala bilanco energetske učinkovitosti obravnavane stavbe. Končni rezultati so potrdili domnevo, da stavba ne ustreza minimalnim zahtevam PURES-a 2010. Za izboljšanje obstoječega stanja sem izvedla posamezne ukrepe in njihove kombinacije. Izbrana kombinacija ukrepov, ki je znižala obstoječe vrednosti pod mejo maksimalno dovoljene, je vsebovala: vgradnjo oken z nižjim koeficientom toplotne prehodnosti, aplikacijo dodatne toplotne izolacije na zunanjo steno in vgradnjo sistema mehanskega prezračevanja. Ker bodo morale biti po letu 2018 vse novozgrajene javne stavbe - skoraj nič-energijske stavbe (sNES), sem preverila, ali obravnavana stavba, ki izpolnjuje zahteve po PURES-u 2010, hkrati izpolnjuje tudi definicijo sNES. V Akcijskem načrtu za skoraj nič-energijske stavbe (AN sNES) so zapisane največje dovoljene vrednosti za letno potrebno toploto za ogrevanje stavbe in letno rabo primarne energije v stavbi ter najmanjši delež obnovljivih virov energije. S prej omenjeno izvedeno kombinacijo ukrepov, stavba ne izpolnjuje vseh zahtev za sNES po AN sNES. Razlog za neizpolnjevanje pogojev za sNES je ta, da PURES 2010 za javne stavbe ne določa največje letne rabe primarne energije Qp in hladu za hlajenje QNC.

• Title: Energy renovation of elementary school Loka extension into a nearly zero-energy building

Abstract

In this diploma thesis I have carried out an energy renovation of a new extension at elementary school Loka in Črnomelj. Currently, the basic legislative document regulating the area of energy efficiency in newly constructed as also renovated buildings in Slovenia is PURES 2010 (Regulations on energy efficiency of buildings). In compliance with its requirements, calculations are made in TOST computer programme, in which I have checked the energy efficiency balance of the building in consideration. Final results have confirmed the assumption that the building does not meet the minimum requirements of PURES 2010. To improve the existing state, I have applied certain measures alone and in combination. The chosen combination of measures which lowered existing critical values to those still allowed involved installing windows with lower heat transfer coefficient, applying extra thermal insulation on external walls and installing a mechanical ventilation system. Since, after 31st December 2018, every newly built public facility will need to comply with nearly zero-energy building (nZEB) requirements, I additionally checked if the building in consideration which now meets PURES 2010 requirements also meets those of nZEB. The nZEB action plan states the annual maximum permitted energy use for heating, annual primary energy necessary for the functioning of the building and the minimum share of renewable energy sources. Although implementing the measure, the building does not meet all nZEB requirements in the action plan due to the reason that, for public buildings, PURES 2010 does not set forth the annual maximums permitted neither for primary energy use nor for cooling systems.
