The following Diploma thesis presents the development of a model for predicting the consumption of electrical and thermal energy in residential buildings. A model which allows the calculation of energy usage on the basis of the surface of the building and additional influencing factors has been developed on the basis of the data on the energy usage in residential buildings. It was made upon the basis of the analysis of data acquired in the area of Dolenjska and is designed to predict the usage of electrical and thermal energy in the apartments, independent houses, and houses with associated farm buildings on the basis of the input data. Each type of the residential building has been modelled separately for the usage of electrical and thermal energy. I managed to develop the model for predicting the usage of electrical and thermal energy which – at 40 cases of test data – successfully predicted the energy consumption at the accuracy of ±35 %, its average deviation from the actual usage being 12 %. V diplomskem delu je predstavljen razvoj modela za napoved rabe električne in toplotne energije v stanovanjskih objektih. Na podlagi podatkov o rabi energije v stanovanjskih objektih je bil razvit model, ki omogoča izračun rabe na podlagi površine objekta in dodatnih vplivnih faktorjev. Model je bil sestavljen na podlagi analize podatkov, pridobljenih na območju dolenjske regije. Narejen je tako, da na podlagi vhodnih podatkov napove rabo električne in toplotne energije v stanovanjih, samostojnih hišah in hišah s kmetijskim poslopjem. Vsak tip stanovanjskega objekta sem modeliral ločeno tako za rabo električne kot tudi toplotne energije. Uspelo mi je razviti model za napoved rabe električne in toplotne energije, ki je pri 40-ih testnih podatkih napovedal rabo energije ±35 % točno, njegovo povprečno odstopanje od dejanske rabe pa je 12 %.

Needed time, energy consumption and referring wood drying costs are among the highest in wood product manufacturing. Analysis of the drying process is very complex as you need to know a lot of different elements influencing drying process. A model that can simulate and analyse conventional drying process by selecting the right drying schedule was prepared. Drying time and energy consumption were calculated. Costs analysis depending on different elements: wood species, wood thickness, initial and final moisture content, climate and construction of drying chamber was done. The model can help us compare and analyse energy efficiency of drying, comparing different drying techniques, and help us with decisions about new investments in our equipment. Potreben čas in porabljena energija pri sušenju lesa, s tem pa tudi stroški sušenja, so med najvišjimi v postopku predelave lesa. Analiza postopka je zato kompleksna in zahteva poznavanje in upoštevanje številnih dejavnikov. Izdelali smo simulacijski model, ki omogoča analizo konvencionalnega sušilnega postopka z vidika izbire ustreznega sušilnega programa, izračunavanja časa sušenja, porabe energije in stroškovno vrednotenje glede na variabilne vhodne podatke: lesna vrsta, debelina lesa, začetna in končna vlažnost, klimatske razmere ter konstrukcija komore. Model omogoča primerjave in analize energijske učinkovitosti postopkov, primerjavo različnih tehnik sušenja in pomaga pri odločitvah o investicijah v opremo.

V diplomskem delu so, na podlagi literature, analizirane dinamične lastnosti različnih tipov vetrnih elektrarn v elektroenergetskem sistemu. Namen dela je ponuditi pregled generacije vetrne energije, pri katerem je poudarek na vplivu vetrnih elektrarn na stabilnost elektroenergetskega sistema. Podani so osnovni mehanizmi delovanja asinhronskega generatorja, dvojno napajanega asinhronskega generatorja in sinhronskega generatorja s pretvornikom, njihovo tranzientno obratovanje in zmožnost dušenja oscilacij. Predstavljen je tudi stabilizator moči, ki z dodatno regulacijo vpliva na obratovanje elektroenergetskega sistema. Na izbranem modelu omrežja je prikazan vpliv različnih tipov vetrnih elektrarn na tranzientno stabilnost in dušenje elektroenergetskega sistema. Generatorji se različno odzivajo glede na njihovo obremenitev. Vsi so stabilni pri nizkih obremenitvah. Pri visokih obremenitvah pa se asinhrosnki generator in sinhronski generator s pretvornikom izkažeta kot tranzientno n This thesis describes the dynamic characteristcs of different types of wind turbines in the power grid. Its purpose is to offer an overview on wind energy generation with an emphasis on the impact of wind generation on the power system stability. The work describes the basic mechanical principles of fixed-speed induction generators, doubly fed induction generators and fully rated converter wind turbines using synchronous generators, their tranzient performance and damping. Also presented, is the power system stabilazer, which offers additional control on power system performance. The impact of different types of wind turbines on the network tranzient stability and damping is also shown in a generic test network. Generators behave differently based on their capacity. All generators are stable at low capacities. Induction generator and fully rated converter wind turbine using synchronous generator are unstable at high capacities. Power system stabilizer improves the stability of bot

In Slovenia, the production of electricity from the wind is neglected, or this share is very small. Major wind farm projects are fairly expensive and hindered by bureaucracy, and the wind situation is not the most favorable, only a small part of the territory of Slovenia is favorable for the installation of major wind power plants. Therefore, it is necessary to concentrate on projects of wind farms up to 20 kW. Within the diploma work, a detailed overview of literature and the market, which forms the basis for the design of wind power plants of small power and a review of existing and possible new construction solutions. At the designing a wind power plant is complyed the requirements and provisions of the applicable standards and regulations, and requirements and criteria for assembly and maintenance. At the design of the wind power plant is complyed wind conditions in Slovenia. In the framework of the diploma will be prepared the proposal of structural solutions, which according to the technical and economic criteria will be adequately evaluated and the optimal design chosen, as the documentation, an integrated drawing of the concept of a wind power plant is attached. V Sloveniji je proizvodnja električne energije iz vetra zanemarjena oziroma je ta delež zelo majhen. Projekti večjih vetrnih elektrarn so precej dragi in ovirani s strani birokracije, pa še vetrne razmere niso najbolj ugodne, saj je le majhen del območja Slovenije ugoden za postavitev večjih vetrnih elektrarn. Zato se je treba skoncentrirati na projekte vetrnih elektrarn do 20 kW. V okviru diplomskega dela je narejen podroben pregled literature in trga, ki predstavlja osnovo pri snovanju vetrnih elektrarn manjših moči, ter pregled obstoječih in možnih novih konstrukcijskih rešitev. Pri zasnovi vetrne elektrarne so upoštevane zahteve in določila veljavnih standardov in predpisov ter zahteve in kriteriji za montažo in vzdrževanje. Pri zasnovi vetrne elektrarne so upoštevane vetrovne razmere v Sloveniji. V okviru diplomskega dela bo pripravljen predlog konstrukcijskih rešitev, ki bodo glede na tehnične in ekonomske kriterije ustrezno ovrednotene, ter izbrana optimalna zasnova kot dokumentacija, ki je priložena kot sestavna risba koncepta vetrne elektrarne.

In the following thesis, we discussed aspects of sustainable design in construction. We presented the principles and indicators of sustainable construction, recognized by the profession. We introduced the concept of integrated planning, which is a relatively new approach to designing of the buildings using BIM. Integrated design is embraced in the BIM design itself, as a holistic approach to building construction, as will be described below. We also described how the software actually verifies environmental aspects such as the orientation of the object, the shape of the building, daylight, energy analysis, collecting rain water and materials. In the practical part of the thesis, we first define the location of the building. Accordingly, we adjusted the type of construction, which should be from environmentally friendly materials that are suitable and efficient for use in Slovenia. Wrapping of the buildng and foundations were adapted to wooden supporting structure, we took into account also the size and intended use of the building. Through the programs we have determined the optimum orientation of the object. This was followed by construction of the object in ArchiCAD BIM software program. We have created a building information model, where we performed energy analysis. The results were compared with results which we got out with program called Knaufinsulation Energy. Finally, the analysis of illumination in specific area, we performed in the program called Velux. With this we demonstrated the potential use of computer tools as to assist in the planning of buildings with minimum burden on the environment, and taking into account the user's comfort. V diplomski nalogi smo obravnavali vidike trajnostnega načrtovanja v gradbeništvu. Predstavili smo načela in indikatorje trajnostne gradnje, ki jih priznava stroka. Predstavili smo tudi koncept integralnega načrtovanja, ki je dokaj nov pristop k projektiranju objektov s pomočjo orodij BIM (angl. Building Information Modelling). Integralno načrtovanje je zaobjeto tudi v samem BIM projektiranju, ki nudi celovit pristop h gradnji stavb. Opisali smo tudi, kako s programsko opremo konkretno preverimo okoljske vidike, kot so: orientacija objekta, oblika stavbe, dnevna svetloba, energetska analiza, zbiranje meteorne vode in materiali. V praktičnem delu diplomske naloge smo najprej definirali lokacijo objekta. Temu smo prilagodili tip gradnje, ki je moral biti iz okolju prijaznih materialov, ki so primerni in smotrni za uporabo v Sloveniji. Ovoj stavbe in temeljenje smo prilagodili leseni nosilni konstrukciji, upoštevali smo tudi velikost in namembnost objekta. S pomočjo programov smo določili najbolj optimalno orientiranost objekta. Sledila je izdelava objekta v BIM računalniškem programu ArchiCAD. Izdelali smo informacijski model stavbe, kjer smo izvedli energetske analize. Rezultate smo primerjali z rezultati iz programa Knaufinsulation Energija. Končno analizo osvetljenosti konkretnega prostora pa smo izvedli v programu Velux. S tem smo prikazali možnosti uporabe računalniških orodij kot pomoč pri načrtovanju objektov s čim manjšo obremenitvijo okolja ter upoštevajoče ugodje uporabnikov.

0.5 g/L and 1.0 g/L. We took notes of daily water usage and statistically processed the data with a computer, using Microsoft Excel 2010, where we tried to figure out the differences by analysis of variance (ANOVA). With the computer program SPSS 17.0, we used t-test for determination of difference characteristics and Pearson's correlation coefficient for analysis of connectedness. We calculated the level of normalized relative transpiration (the NRT) from absolute water consumption. At the end of the experiment, we measured height, thickness of the shoots and counted the number of shoots and made a graphic comparison between them. The results: The clone V160 used most of water with all concentrations of NaCl. In clone V093, NRT was the highest with the NaCl concentration of 1.0 g/L, in clone V160 at concentration 0,2 and 0.5 g/L, and in clone V052 at concentration 0.5 g/L. In clone V052, at NaCl concentration of 0.2 g/L, NRT was less than 100% from the beginning of the experiment. Discussion and conclusion: In our experiment, NaCl did not pile up in the ground to such extent that it would slow down the transpiration and affect the growth of willow trees. Based on the obtained results, we can expect that in S. alba clones V093, V160 and V052 it would not come to effects of NaCl on the efficiency of treatment of urban wastewater in real ETS at a concentration of NaCl up to 1.0 g/L in 1 vegetative period. We assume that the results in real ETS could differ from ours, because we did not use wastewater that could boost the uptake of water and speed up the accumulation of NaCl. In addition, it would make sense to monitor the response of willow trees and the interaction of various factors on the growth of willow trees during more vegetative periods. 0,5 g/L in 1,0 g/L. Beležili smo dnevno porabo vode in podatke statistično obdelali z računalniškim programom Microsoft Excel 2010, kjer smo razlike ugotavljali z analizo variance (ANOVA). Z računalniškim programom SPSS Statistics 17.0 smo za ugotavljanje značilnosti razlik uporabili t-test in za analizo povezanosti Pearsonov korelacijski koeficient. Iz absolutne porabe vode smo izračunali stopnjo normalizirane relativne transpiracije (NRT). Na koncu poskusa smo izmerili višino, debelino poganjkov, prešteli število poganjkov in naredili grafično primerjavo med njimi. Rezultati: Klon V160 je pri vseh koncentracijah NaCl porabil največ vode. Pri klonu V093 je bila največja NRT pri koncentraciji NaCl 1,0 g/L, pri klonu V160 pri koncentraciji 0,2 in 0,5 g/L in pri klonu V052 pri koncentraciji 0,5 g/L. Pri klonu V052 je bila NRT pri koncentraciji NaCl 0,2 g/L od začetka poskusa nižja od 100 %. Razprava in sklep: V našem poskusu se NaCl ni nakopičil v zemljo do te mere, da bi zaviral transpiracijo in vplival na rast vrb. Na podlagi pridobljenih rezultatov lahko pričakujemo, da pri klonih vrbe S. alba V093, V160 in V052 ne bi prišlo do vplivov NaCl na učinkovitost obdelave odpadne komunalne vode v realnem ETS pri koncentraciji NaCl do 1,0 g/L v 1 vegetacijski dobi. Predvidevamo, da bi se lahko rezultati v realnih ETS razlikovali od naših, saj nismo uporabili odpadne komunalne vode, ki bi lahko povečala privzem vode in pospešila kopičenje NaCl. Poleg tega bi bilo smiselno spremljati odziv vrb in medsebojno delovanje različnih dejavnikov na rast vrb več vegetacijskih dob. Introduction: Evapotranspiration systems (ETS) are among the cleaning plants for treatment and disposal of municipal wastewater, where all wastewater is used to grow plants such as willows. In the ETS, the concentration of salt (NaCl) eventually increases, which has an impact on the efficiency of wastewater treatment and the growth of willow trees. Purpose: With the help of pot experiment, we wanted to determine the impact of different concentrations of NaCl on growth and evapotranspiration of willows in the ETS and compare responses of salinity of 3 different clones of willow trees. Working methods: The pot experiment took place in the greenhouse on 3 clones of White Willow (Salix alba) in the 5 test portions and control batch without NaCl (a total of 90 samples). We tested the following concentrations of NaCl: 0.1 g/L Uvod: Evapotranspiracijski sistemi (ETS) sodijo med čistilne naprave za obdelavo in odstranjevanje komunalnih odpadnih voda, kjer se vsa odpadna voda porabi za rast rastlin, kot so vrbe. V ETS se sčasoma povečajo koncentracije soli (NaCl), kar vpliva na učinkovitost obdelave odpadne vode in rast vrb. Namen: S pomočjo lončnega poskusa smo želeli ugotoviti vpliv različnih koncentracij NaCl na rast in evapotranspiracijo vrb v ETS in primerjati odzive na slanost 3 različnih klonov vrb. Metode dela: Lončni poskus je potekal v rastlinjaku na 3 klonih bele vrbe (Salix alba) v 5 paralelkah in kontrolno serijo brez NaCl (skupaj 90 vzorcev). Testirali smo naslednje koncentracije NaCl: 0,1 g/L 0,2 g/L 0.2 g/L

terasni bloki v Kosezah, atrijski bloki na Viču in stolpnice ob Streliški cesti. Pri vsakem posameznem modelu zazidave je bil opazovan objekt, ki je glede na sončne dobitke lociran najbolj neugodno. S programom Rhinoceros 3D sem izdelala modele pozidave, na katerih je bila nato izpeljana parametrična študija tistega faktorja, ki ima največji vpliv na prejeto sončno sevanje. Prvi parameter, ki je bil opazovan je bila razdalja, kjer sem povečevala ali zmanjševala razmake med objekti, drugi parameter opazovanja je bila rotacija, kjer sem objekte sukala od 0 do 30° v smeri od juga proti zahodu, naslednji parameter je bil razpon notranjega dela atrija, s čimer sem spreminjala velikost notranjega dvorišča. Zadnji parameter obravnave je bila višina, kjer sem spreminjala višino sosednjih objektov. Izvedeni sta bili dve vrsti analize the first was done with the software tools Grasshopper and Diva, where I calculated the average annual solar radiation received by the treated object, and the other included the calculation of the energy required for heating the object in the UMI software tool. The analysis showed that when designing energy efficient buildings, the appropriate density should be taken into consideration, where the solar potential depends on the distance between the objects, the floor area ratio and the consequent mutual shading of objects, as well as the orientation where is the most important the maximized exposure of surfaces to sunlight and its associated shape and object geometry. prva je potekala s programskima orodjema Grasshopper in Diva, kjer sem izračunala, kolikšno je povprečno letno prejeto sončno sevanje obravnavanega objekta, druga pa je obsegala izračun energije, potrebne za ogrevanje objekta v programskem orodju UMI. Analiza je pokazala, da moramo pri načrtovanju energijsko učinkovitih stavb upoštevati primerno gostoto pozidave, kjer je sončni potencial odvisen od razmaka med objekti, faktorja zazidljivosti in posledičnega medsebojnega senčenja objektov, ter tudi orientacijo, kjer je najbolj pomembna čim večja izpostavljenost površin sončnemu sevanju ter z njo povezano obliko in geometrijo objekta. terraced blocks in Koseze, atrium blocks on Vič and skyscraper along Streliška cesta street. For each individual model the building, which is the most unfavorable in terms of solar gains was selected. With the Rhinoceros 3D program, I created the urban patterns models, where a parametric study of the factor which has the greatest influence on the received solar radiation was performed. The first parameter that was observed was the distance between the buildings, where I increased or reduced the spacing between the objects the second parameter of the observation was the rotation, where the objects were rotated from 0 to 30 ° in the direction from south to west. The next parameter was the range of the inward part of the atrium, which changed the size of the inner courtyard. The last parameter of the discussion was the building height where I changed the level of the adjacent objects. Two types of analysis were performed This graduation theses includes a study of the parameters that influence the energy efficiency of the settlement. Influence of factors, that utilization of solar potential depends upon, was observed. According to the discussed apartment building typology, three different, existing urban patterns in Ljubljana were selected Diplomsko delo zajema študijo parametrov, ki vplivajo na energijsko učinkovitost naselja. Opazovan je bil vpliv dejavnikov, od katerih je odvisna izraba sončnega potenciala. Glede na obravnavano večstanovanjsko tipologijo so bili izbrani trije različni, obstoječi vzorci pozidave v Ljubljani

Energy efficiency is an area that is becoming more and more actual. To achieve energy efficiency, different approaches are required. These approaches must be based on ISO 50001 standard and directives of the European Union to assure quality. With the implementation of effective approaches, we reduce energy consumption, costs and extend the lifespan of heating systems, ventilation and air conditioning. Moreover, the comfort of the occupants is improved. The aim of the master thesis is to show the processes by which any building manager optimizes the use of energy with minimal investment. At the Faculty of electrical engineering, we have analysed the condition of the building and its systems of heating, ventilation and air conditioning. For the purpose of analysis, we thoroughly reviewed the state of electrical installations. Where necessary, we created new labels for mentioned installations. For the analysis, we created a tree structure and redesigned building layouts which contained electrical cabinets. With help of this analysis, we have developed procedures that can be performed at the faculty and are suitable for other similar public and private buildings. Soft measures are processes that users can implement themselves and contribute to lower energy consumption. We wrote what are the possible measures to regulate the heating station and what measures for the rooms. We wrote measures that would contribute to the improvement of air quality and a more optimal temperatures in the rooms without an excessive use of heating through the heating station. To determine the energy consumption costs of the faculty, Information system and Energy accounting system were established. A draft of Quality manual was made, which defines duties and persons who must perform these duties. Users often do not know what the procedures for the reduction of energy consumption are. That is why information courses are needed for employees, so that they get enough information to perform these procedures Energetska učinkovitost je področje, ki je vedno bolj aktualno. Za dosego energetske učinkovitosti so potrebni različni pristopi, ki se za zagotovitev kakovosti opirajo na standard ISO 50001 in direktive Evropske unije. Z izvajanjem pristopov učinkovito zmanjšamo rabo energije, stroške in podaljšamo življenjsko dobo sistemov ogrevanja, prezračevanja in klimatizacije. Poleg tega se izboljša tudi udobje uporabnikov prostorov. Cilj magistrskega dela je prikaz postopkov, s katerimi lahko vsak upravljalec stavbe optimizira rabo energije z minimalnimi investicijskimi vložki. Na Fakulteti za elektrotehniko smo analizirali stanje stavbe in njenih sistemov ogrevanja, prezračevanja in klimatizacije. Za namen analize smo najprej temeljito pregledali stanje električnih inštalacij. Kjer je bilo potrebno, smo izdelali nove oznake omenjenih inštalacij. Za analizo smo izdelali drevesno strukturo in prenovili tlorise lokacij električnih omar. S pomočjo analize smo izdelali postopke, ki se lahko izvedejo na fakulteti, primerni pa so tudi za druge podobne javne in zasebne stavbe. Mehki ukrepi so postopki, ki jih uporabniki lahko izvedejo sami in s tem pripomorejo k nižji rabi energije. Zapisali smo, kateri so možni ukrepi na regulaciji toplotne postaje in kateri v prostorih. Za prezračevanje in klimatizacijo smo zapisali ukrepe, ki bi pripomogli k izboljšanju kakovosti zraka in bolj optimalni temperaturi v prostoru, ne da bi s tem obremenili ogrevanje preko toplotne postaje. Za ugotavljanje stroškov na fakulteti je bil vzpostavljen informacijski sistem in energetsko knjigovodstvo. Izdelan je bil tudi osnutek poslovnika kakovosti, v katerem so zapisane dolžnosti in osebe, ki morajo te dolžnosti izvajati. Uporabniki sami velikokrat ne vedo, kakšni so postopki za znižanje rabe energije. Zato so potrebna izobraževanja za zaposlene, preko katerih dobijo dovolj informacij, da lahko izvajajo postopke.

This thesis deals with the topic of energy efficiency of LED diode and light-emitting lights that are made of them. In the theoretical part, we focus primarily on a brief historical overview of the development of lights, among which we explain more precisely how LED diodes and lights have evolved and shaped over time. Following we describe different types of lamps and define how LED lamps differ from them, and how these differences affect their higher energy efficiency. LED lamps allow the consumption of electricity, which is more rational than the use of other types of lamps, such as, e.g., classical filament lamps that consume more electricity and emit less light. Similarly, compared to LEDs, their life span is shorter. The diploma points out some advantages of the LED lamps, and points to some of their weaknesses, which are mainly reflected in price and their temperature sensitivity. In the last section, we address questions about the effectiveness of LED lamps, focusing on their energy efficiency, the light pollution and the recycling of LEDs. At the end we present the findings of comparison analysis of costs which was hypothetically made for four-member household. Pričujoče diplomsko delo obravnava tematiko energetske učinkovitosti LED diod in iz njih izdelanih LED svetil. V teoretičnem delu se sprva osredotoči na kratek zgodovinski pregled razvoja svetil, med katerimi natančneje pojasni, kako so se skozi zgodovino razvijale in oblikovale LED diode in svetila. V nadaljevanju opiše različne vrste svetil in opredeli, kako se LED svetila od njih razlikujejo, ter kako te razlike vplivajo na njihovo večjo energetsko učinkovitost. LED svetila omogočajo rabo električne energije, ki je racionalnejša od rabe drugih vrst svetil, kot so recimo klasične žarnice z žarilno nitko. Prav tako je v primerjavi z LED svetili njihova življenjska doba krajša. Diplomsko delo predstavi prednosti LED svetil, a pri tem opozori tudi na nekatere njihove slabosti, ki se kažejo predvsem v ceni in njihovi temperaturni občutljivosti. V zadnjem sklopu se loti vprašanja učinkovitosti LED svetil s poudarkom na njihovem električnem izkoristku, svetlobnem onesnaževanju in recikliranju LED svetil. Na koncu je predstavljena primerjalna analiza stroškov, ki je bila hipotetično narejena za štiričlansko gospodinjstvo.

The purpose of this diploma thesis is the energy balance calculation of an apartment building in Logatec, at the address Sončni log 1 and 1a. This data represents the energy efficiency or inefficiency of the apartment building and can be used to introduce renovation possibilities, with which the criteria of an energy efficient building, according to the Regulations on Energy Efficiency in Buildings (PURES 2010, Ur. l. RS, nr. 52/2010: 7840), can be met. . The calculations were carried out using the KI Energija software that is based on the methodology of the Regulations PURES 2010 and the directive Tehnična smernica - učinkovita raba energije (TSG nr. 1-004, 2010). Also carried out was a comparison of the actual U-factors with those in effect at the time of construction planning, because of the inadequate values of thermal transmittance factors of constructional complexes. The KI Energija computer software recorded energy balance calculations which indicate energy efficiency. The chosen building’s energy balance does not meet the criteria of PURES 2010, because the legislation in effect at the time of construction planning, in 2005, involved criteria that were less strict. The most substantial deviations occur in the split-level constructional complex, which divides the heated zone and the garage, because it is not thermally insulated and the U-factor exceeds the threshold by 1,1 W/(m2K). The most energy-efficient renovation measures include additional thermal insulation of split-level constructional complexes and the non-permeable exterior, while also installing a mechanical ventilation system with heat recovery. Namen diplomske naloge je izračun energetske bilance za večstanovanjsko stavbo v Logatcu, na naslovu: Sončni log 1 in 1a, v okviru katere želimo prikazati energijsko ustreznost oziroma neustreznost večstanovanjske stavbe in podati predloge sanacije, s katerimi lahko dosežemo kriterij energetsko učinkovite stavbe po Pravilniku o učinkoviti rabi energije v stavbah (PURES 2010, Ur. l. RS, št. 52/2010: 7840). Izračun je izveden s programom KI Energija, ki temelji na metodologiji po PURES-u 2010 in Tehnični smernici - učinkovita raba energije (TSG št. 1-004, leto 2010). Zaradi neustreznih vrednosti faktorjev toplotne prehodnosti konstrukcijskih sklopov je narejena primerjava med dejanskimi U faktorji in faktorji, ki so bili veljavni v času projektiranja. S pomočjo računalniškega programa KI Energije je izpisana tudi računska energetska izkaznica, ki je pokazatelj energetske učinkovitosti. Energetska bilanca izbrane stavbe ne ustreza kriterijem PURES 2010, saj je bila v času projektiranja leta 2005 veljavna zakonodaja z manj strožjimi kriteriji. Največja odstopanja so pri medetažnem konstrukcijskem sklopu, ki ločuje ogrevano cono in garažo, ker ni toplotno izoliran in U faktor presega mejne vrednosti za 1,1 W/(m2K). Energetsko najučinkovitejši sanacijski ukrepi so dodatna toplotna izolacija medetažnih konstrukcijskih sklopov in netransparentnih zunanjih površin ter vgradnja mehanskega prezračevanja z rekuperacijo toplote.
