Opis:V vrtcu Solkan je raba energije za ogrevanje visoka in z njo so povezani tudi visoki obratovalni stroški. Z energijsko prenovo bi zmanjšali rabo energije in z njo povezane obratovalne stroške, hkrati pa bi izboljšali kakovost bivanja v stavbi. V magistrskem delu smo izvedli analizo trenutnega stanja ovoja stavbe in sistemov. Nadalje smo predlagali različne variante prenove, ki so v skladu s smernicami novega Energetskega zakona in v skladu z Akcijskim načrtom za skoraj nič-energijske stavbe. Pri variantah prenove smo ocenili okoljske, ekonomske in energijske učinke ter predlagali stroškovno optimalno varianto energijske obnove vrtca Solkan. Zmanjšanje toplotnih izgub smo dosegli z dodatnimi plastmi izolacijskega materiala, ki bi se jih dodalo na obstoječo konstrukcijo stavbe ter z zamenjavo stavbnega pohištva. Toplotne izgube smo še dodatno zmanjšali z vgradnjo mehanskega prezračevanja z rekuperacijo odpadne toplote. V energijsko prenovo smo s toplotnimi črpalkami za ogrevanje prostorov in pripravo tople sanitarne vode vključili obnovljive vire energije, ki so eden izmed kriterijev skoraj nič-energijske stavbe. V finančni analizi se je kot najugodnejša izkazala varianta z vgradnjo dodatnih plasti izolacijskega materiala na obstoječo konstrukcijo stavbe, zamenjavo stavbnega pohištva ter uporabo toplotnih črpalk za ogrevanje in pripravo tople sanitarne vode. Na ta način smo kriterij sNES glede 50-% minimalnega deleža OVE s preko 80 % presegli brez težav, medtem ko smo kriterij rabe največ 65 kW h/m2a primarne energije na enoto kondicionirane površine dosegli in s 56,81 kW h/m2a tudi presegli, vendar šele z vgradnjo mehanskega prezračevanja z rekuperacijo toplote.

Naslov:Renovation of the Kindergarten Solkan with the nearly zero-energy buildings criteria: a variant analysis : master's thesis
Opis:In the Solkan kindergarten the energy consumption for heating is high and it is linked to high operating costs. The energy renovation would serve to reduce energy consumption and cut down on operational costs while improving living comfort in the building. In this master thesis, an analysis of the current state of the building's envelope and systems was carried out. Furthermore, different renovation variants were proposed, which are in accordance with the guidelines of the new Energy act and also in accordance with the Action plan for the nearly zero energy buildings. In different renovation variants the environmental, economic and energy impacts were evaluated, and the cost-optimal variant for the energy renovation of the Solkan kindergarten was proposed. The reduction of heat losses was achieved by installation of additional insulating material layers, which were added to the existing structure of the building, and by replacement of joinery and carpentry work. Heat losses were further reduced by installation of mechanical ventilation with heat recovery. By application of heat pumps for space and sanitary water heating we included in the energy renovation the use of renewable energy sources, which represents one of the criteria for nearly zero energy buildings. Financial analysis has shown the most favorable variant to be the one that included installation of additional insulating material onto the existing structure of the building, replacement of joinery and carpentry work, as well as application of heat pumps for space and sanitary water heating. In this way the criterion sNES regarding the 50 % minimum share of RES was easily exceeded by over 80 %. The criterion for the use of no more than 65 kW h/m2a of primary energy consumption per unit of conditioned area was successfully met, and energy consumption was even further lowered to 56,81 kW h/m2a, however, only after installation of mechanical ventilation with heat recovery.
