V diplomski nalogi smo obravnavali stavbo Fakultete za strojništvo Univerze v Ljubljani. Namen je bil analizirati obstoječe stanje stavbe z vidika kakovosti notranjega okolja in rabe energije. Določili smo zahtevane in priporočene vrednosti parametrov, kakovosti notranjega okolja ter predstavili, kako se odstopanja odrazijo v mogočem negativnem vplivu okolja na zdravje in udobje ljudi. S pomočjo vprašalnika o kakovosti notranjega okolja smo pridobili mnenja uporabnikov ter s tem informacije o obstoječem stanju. Za izračun gradbeno fizikalnih parametrov izbranih konstrukcijskih sklopov smo uporabili program KI energija 2017, v katerem smo izračunali tudi rabo energije. Rezultati izračuna, ki smo jih podrobneje obravnavali, so toplotna prehodnost posameznih konstrukcijskih sklopov, kondenzacija na njihovi površini oz. v konstrukciji, faktor površinske temperature, koeficient specifičnih transmisijskih izgub celotne stavbe, letna potrebna toplota za ogrevanje stavbe in specifični letni potrebni hlad za hlajenje. Rezultate smo predstavili in primerjali z drugimi, že obstoječimi izračuni, da smo preverili natančnost le-teh. Analizirali in predstavili smo več variant prenove (gradbeniški ukrepi, strojniški ukrepi in kombinacija obeh). Poiskali smo vso zakonodajo na področju stavb za izobraževanje in znanstvenoraziskovalno delo (raba energije, gradbena fizika in kakovostno notranje okolje) ter preverili, v kakšni meri izpolnjujemo pogoje, s podanimi variantami prenove. Glede na analizo prenov smo izpostavili prednosti in slabosti vsake izmed variant ter izbrali najoptimalnejšo. Za to se je izkazala varianta s kombinacijo gradbeniških in strojniških ukrepov, kjer smo izbrali dodatno toplotno izolacijo in mehansko prezračevanje z vračanjem toplote. Pri takšni prenovi se izrazito zmanjša potreba po toplotni energiji, hkrati pa je kakovost zraka, iz vidika prezračevanja, najboljša ob upoštevanju sprotnega čiščenja in vzdrževanja sistema ter optimalnih količinah svežega zraka. Cilj celovite prenove je bil v dosegu optimalne učinkovitosti stavbe in strojnih sistemov, ki se odrazi v zdravih in udobnih razmerah za uporabnike.

Sekundarni naslov: ǂThe ǂrenovation of the Faculty of Mechanical Engineering, University of Ljubljana in order to achieve optimal indoor environmental quality and minimal building energy use
Sekundarni povzetek: In our diploma thesis focuses on the building of the Faculty of Mechanical Engineering, University of Ljubljana. The purpose of our thesis was to analyse the existing condition of the building in terms of the indoor environmental quality and energy use. We determined the required and recommended values of the parameters. We determined the required and recommended values of the parameters of indoor environmental quality and presented how the deviations are reflected in the possible negative impact of the environment on human health and comfort. With the help of a questionnaire on the quality of the internal environment, we obtained the opinions of users and thus the information on the current situation. To calculate the construction and physical parameters of the selected structural assemblies we used the KI energija 2017 program, in which we also calculated energy use. The results of the calculation, which were discussed in more detail, are the thermal conductivity of individual structural assemblies, condensation on their surface or in the structure, the surface temperature factor, the coefficient of specific transmission losses of the whole building, the annual energy use for heating and the specific annual energy use for cooling. We presented the results and compared them with other already existing calculations to check the accuracy of these. We analysed and presented several renovation variants (civil engineering measures, mechanical engineering measures, and a combination of both). We searched for all legislation in the field of buildings for education and scientific research (energy use, building physics and a quality of internal environment) and checked the extent to which we meet the conditions with the given renovation variants. According to the analysis of renovations, we highlighted the advantages and disadvantages of each of the variants, and chose the most optimal one. For this, a variant with a combination of civil engineering and mechanical engineering measures proved to be appropriate, where we chose additional thermal insulation and mechanical ventilation with heat recovery. Such a renovation significantly reduces the need for thermal energy, and at the same time the air quality, from the point of view of ventilation, is the best, taking into account the ongoing cleaning and maintenance of the system and the optimal amounts of fresh air. The goal of the comprehensive renovation was to achieve optimal efficiency of the building and mechanical systems, which is reflected in healthy and comfortable conditions for users.
