This thesis deals with current topics of today, such as the issue of valuation of real estate and energy performance of buildings. The content is divided into a theoretical part where the first general and then specifically looks at the issue, and the practical part, which contains the calculations for determining the price of the selected house by direct comparison and cost methods by decree. It also specifies the energy performance of the house in its current state, and after the thermal insulation. Orientation also the return on the investments made from the perspective of the investor. The aim of this study is to assess the extent to which there is an increase in the price of a house due to the thermal insulation.

The subject of diploma thesis is energy assessment of the building according to BREEAM methodology. First chapter overviews certification systems. The main part of the thesis consists of energy assessment of the building with application of BREEAM requirements. Specifically, building, its systems and interior environment analysis has been carried out, determination of heat transfer coefficients and production of energy performance certificate. Energy assessment of the building is carried out in accordance to BREEAM criteria. Third part contains analysis and evaluation of thermal comfort.

The master project is divided into three parts. The problematic of first and second part is kindergarten building, its technical equipment and management systems. The third part deals with financial, energy and environmental comparison of different heat systems. The kindergarten is single-storey building without basement and is located in Ronov nad Doubravou, Czechia. Building is based on strip footing and structural system is masonry wall system with gable roof. Material of both load-bearing and non-bearing walls are sand-lime blocks. External walls are insulated by external thermal insulation composite system. Vertical structures are designed from wooden lattice truss. The building site contains also outdoor parking lot and a garden with a playground.

Various studies in the EU have examined the effect of Energy Performance Certificates (EPCs) on the real estate market, examining market values, rental values, and yields. However, there is dissent on the effect of EPC. The study tests for the impact of EPC alone and in relation to socioeconomic attributes on transaction prices of residential properties in Stockholm, Sweden. The thesis analyzes real transaction data of the 26 municipalities of the Stockholm region. Firstly, the research aims to determine if the energy efficiency capitalizes on residential property prices and if and to what extent the capitalization varies within the municipalities of Stockholm. Lastly, the study examines how income and education influence the prices of energy-efficient properties. The applied approaches follow the hedonic pricing method, namely, the OLS (Ordinary Least Squares) and spatial models. After analyzing more than 40,000 observations, the regression results indicate that high energy efficiency is reflected in the price premium of apartments and dwellings. For example, energy-efficient apartments with an EPC grade of A, B, or C achieve a price premium of around 0.99% compared to apartments with lower EPC grades between D-G. The results indicate a more considerable price premium of approximately 3.33% for energy-efficient dwellings. Another result of the study is that the capitalization of energy efficiency varies strongly between the municipalities of Stockholm. For apartments, the data implies substantial differences ranging from -15% in Danderyd to +14.2% in Upplands-Bro. The “local” premium for energy-efficiency dwellings ranges from 3% in Stockholm municipality to 9.5% in Norrtälje. Even though the results were significant, they need to be interpreted with caution as the sample size of some municipalities was relatively small. The last aspect of the study incorporates the issue of socioeconomic variables, income, and education level. The initial hypothesis was that high income and education would be correlated with higher energy performance certificate (EPC) grades. However, the results suggest a negative correlation between income or education level with EPC grade. These results imply that market participants with higher income and education are less likely to seek a higher EPC grade. The reason could be that these high-income households have a lower sensitivity to rising energy prices and fewer issues to afford the old but prestigious housing stock. / Olika studier inom EU har undersökt effekten av energiprestanda certifikat (EPC) på fastighetsmarknaden, marknadsvärden, hyresvärden och avkastning. Det finns dock oenighet om effekten av EPC. Denna studie testar effekten av EPC enbart och i relation till socioekonomiska attribut på transaktionspriser för bostadsfastigheter i Stockholm, Sverige. Avhandlingen analyserar verkliga transaktionsdata för 26 kommunerna i Stockholmsregionen. För det första syftar forskningen till att avgöra om energieffektiviteten i bostadsfastigheter påverkar priser och om och i vilken utsträckning kapitaliseringen varierar inom Stockholms kommuner. Slutligen undersöker studien hur inkomst och utbildning påverkar priserna på energieffektiva fastigheter. De tillämpade metoderna följer den hedoniska prissättningsmodellen, nämligen OLS (Ordinary Least Squares) och rumsliga modeller. Efter att ha analyserat mer än 40 000 observationer tyder regressions resultaten på att hög energieffektivitet återspeglas i prispåslaget för lägenheter och bostäder. Till exempel uppnår energieffektiva lägenheter med EPC-graden A, B eller C en prispåslag på cirka 0,99 % jämfört med lägenheter med lägre EPC-klasser mellan D-G. Resultaten indikerar en mer betydande prispåslag på cirka 3,33 % för energieffektiva bostäder. Ett annat resultat av studien är att kapitaliseringen av energieffektivisering varierar kraftigt mellan Stockholms kommuner. För lägenheter innebär uppgifterna stora skillnader från -15 % i Danderyd till +14,2 % i Upplands-Bro. Den ”lokala” premien för energieffektiva bostäder sträcker sig från 3 % i Stockholms kommun till 9,5 % i Norrtälje. Även om resultaten var signifikanta måste de tolkas med försiktighet eftersom urvalsstorleken i vissa kommuner var relativt liten. Den sista aspekten av studien tar upp frågan om socioekonomiska variabler, inkomst och utbildningsnivå. Den initiala hypotesen var att hög inkomst och utbildning skulle vara korrelerad med högre energiprestanda certifikat (EPC) betyg. Resultaten tyder dock på ett negativt samband mellan inkomst eller utbildningsnivå med EPC-betyg. Dessa resultat tyder på att även om EPC är positivt kapitaliserat i bostadspriserna är marknadsaktörer med högre inkomst och utbildning mindre benägna att söka ett högre betyg i EPC. Detta på grund av mindre känslighet för ökningar i energipriser och överkomliga priser för det gamla bostadsbeståndet.

Energieffektivisering av byggnadsbeståndet är en viktig del av EU:s klimatarbete, och systemet med energideklarationen (EPC) är ett centralt politiskt verktyg för ändamålet. Forskningen om hur EPC påverkat fastighetsmarknaden är dock inte helt entydig. Fastän statistisk forskning huvudsakligen tyder på ett samband mellan en högre energiklass och en högre köpeskilling, marknadsförs inte energiklassen som en lönsam grön strategi. Genom att intervjua svenska fastighetsaktörer om deras syn på och användning av energideklarationen ämnar denna studie undersöka om EPC-märkningen (energiklassen), som ingår som ett obligatorium i alla försäljnings- och hyresannonser, spelar någon roll för betalningsvilja och investeringsbeslut. I det fall det finns en lönsamhet i energieffektivitet borde energideklarationen vara ett värdefullt informationsverktyg. Den borde dessutom leda till en kontinuerlig förbättring av energiklasserna i det svenska byggnadsbeståndet och på lång sikt bidra till att uppnå klimatmål på nationell och internationell nivå. År 2022 väntas tillägg till befintlig EU-lagstiftning som kommer öka fokus på energieffektivisering för att uppnå de globala klimatmålen, vilket gör det än mer angeläget att utreda EPC-systemets tillämpning och potentiella fördelar på den svenska fastighetsmarknaden. Resultaten av denna studie visar att EPC-märkningen inte har haft en speciellt stor inverkan på marknaden sedan den infördes eftersom den inte skapar ekonomiska incitament att investera i energieffektivitet, och de energieffektiviseringsåtgärder som deklarationen föreslår är alltför generiska och bristfälliga. På det hela taget har deklarationen en svag ställning och är för närvarande främst begränsad till en formalitet. Värdet av en bra energiklass kommer dock sannolikt att öka till följd av implementeringen av EU-taxonomin, och denna ökning beror till stor del på de finansiella fördelar en bra energiklass kan medföra. Resultaten i denna uppsats ifrågasätter ett energiklassningssystem i Sverige som inte fungerar som det ska eftersom det inte bidrar till att öka energieffektiviteten i det svenska byggnadsbeståndet, och understryker vikten av kompletterande politik som kan uppmuntra investeringar i rätt riktning. / Improving the energy efficiency of the building stock is an important part of the EU's climate work, and the Energy Performance Certificate (EPC) scheme is a key policy tool for this purpose. Research on the impact of the Energy Performance Certificates (EPC) on the real estate market is not entirely clear. While statistical research mainly suggests a correlation between a better energy class and a higher price, the energy class is not being marketed as a profitable green strategy. By interviewing Swedish real estate actors about their views on the energy performance certificate (EPC) this study seeks to investigate whether the EPC label, which is included as a mandatory element in all sales and rental advertisements, plays a role in willingness to pay and investment decisions. If there is a profitability in energy efficiency, the EPC should be a valuable information tool. In addition, it should lead to a continuous improvement of the energy performance of the Swedish building stock, and in the long term contribute to achieving climate goals at national and international level. In 2022, amendments to existing EU legislation are expected that will increase the focus on energy efficiency to achieve the global climate goals, making it even more urgent to investigate the application and potential benefits of the EPC scheme in the Swedish real estate market. The result of this study shows that the EPC label has not had a significant impact on the market since its introduction, since it does not create financial incentives to invest in energy efficiency and since the energy efficiency improvement measures proposed by the declaration are too generic and insufficient. On the whole, the energy performance certificate has a weak position and is currently mainly limited to a formality. However, the value of a good energy class is likely to increase as a result of the implementation of the EU taxonomy, and this transition is largely dependent on the financial benefits a good energy rating can bring. The findings of this paper call into question an energy labeling scheme in Sweden that is not working as it should, that is, to increase energy efficiency in the Swedish building stock, and underline the importance of complementary policies that can encourage investment in the right direction.

The aim of this diploma thesis is to revitalize the selected type of panel house in the selected locality in order to meet the standards of international certification for the design and sustainable construction of buildings. First, the thesis analyzes the chronological development of the panel housing estates in Brno and compares the individual structural systems that were historically used for panel construction in Brno. Furthermore, the most used certification methodologies are compared and a specific certification is selected for next simulation. The chapter called solution is focused on performing a simulated certification process for design and sustainable construction of selected panel building, in three phases of its revitalization. The hypotheses describing the individual phases of revitalization are intended to confirm or disprove the achievement of this objective, moreover to say the extent of revitalization that has to be done in order to achieve our goals.

The diploma thesis is focused on the price of a family house in the village of Kosov and its dependence on the Energy Performance Certificate of this house. The price of the family house, given its current condition, is determined in accordance with applicable regulations and taking into account the energy demands, the property facilities and the technical wear of the property. Then a measure reducing the building energy performance and thus financial demands regarding heating and operation of the house is proposed. The result of the thesis is the evaluation of the price of the property depending on the implemented measures and the new technical condition of the family house.
