The diploma thesis analyzes the overall life cycle costs of a passive family house. In the theoretical part the thesis deals with the definitions of concepts needed to understand the given issue and to determine the costs in individual parts. In the practical part the knowledge and procedures to two passive family houses are applied.

Diploma thesis "Low-energy building" presents low-energy construction trends and their price comparision with conventional contruction. This thesis defines basic low-energy building terms, both building and construction work evaluation concepts and specifics of low-energy construction. Practical outcome is comparision between passive and conventional buildings, including economic appraisal.

This master´s thesis is focused on detterminations of the difference between the standard price of a detached passive house and selected detached houses in Chomutov and its surroundings. The theoretical part of the thesis describes the basic terms used in real estate valuation. The main task of this thesis is in Chomutov establish the standard price of houses with regard to their implementation, to evaluate land forming their accessories and assess standart value house without land, in order to eliminate the influence of land price to the price of the property. For valuation has been selected 10 houses from the Ústecký kraj of 3 districts (Chomutov, Louny and Most).

This Master´s thesis deals with the analysis of the effectiveness of ventilation systems. The key concept of the thesis is HVAC system in buildings with low energy demand. In the most comprehensive chapter are some concepts clarified: air tightness, ventilation, air conditioning, heating and hot water preparation. The aim of the thesis is to define passive house in terms of acquisition and operating costs, including the ventilation system and to make comparison with systems applied in conventional construction with focusing on assessment of effectiveness of ventilation equipment.

The Master thesis is focused on rating the specifics of passive houses and assessment whether the energy savings in the operation of passive house will cover the increased cost of construction. The theoretical part deals with the history and development of passive houses, application of natural materials, sustainable resources of energy and indicators for the evaluation of economic efficiency. The practical part describes passive and standard house. On the standard house, there is processed financial plan. Reference objects are compared, followed by evaluation of the return on the additional costs of the passive house.

A diploma thesis is dealing about cost method of valuation for passive family houses, which popularity is growing. Aim of the thesis is determinate amount of share cost structure of real buildings and compares it with valuation decree. First part of this thesis analyses issue of passive houses as well as cost method of valuation issue. There are three family houses valuated by detail itemized budget. Than share cost structure is confronted and evaluated by valuation decree no. 441/2013 Sb. As well thesis shows basic specifics of passive houses valuation. Also thesis brings answers for economical questions. For example how much passive house costs or how much is passive house more expensive than usual house.

The aim of this thesis is to compare economic investment in passive houses and conventional construction of a house. Furthermore, this thesis is focused on introducing problematics connected to construction of passive house, main characteristics, differences in used materials including review of advantages and disadvantages of their implementation. Assessment is based on return ability of initial investments generated by lowering operational costs. Main part of this thesis is aimed on compression of costs both before and in use of a house.

The aim of this work is the explanation of the issue of passive houses and renovation of existing buildings to passive energy standard. Another task of the work is a feasibility study of building renovation of the "Tuzex" for the needs of Center of sustainable construction in Brno. Part of this study is to create a marketing analysis, design of organizational project management, a description of technical solution, impact assessment project on the environment and in particular evaluating the economic efficiency of investment. The result of this work is to evaluate the feasibility of the project under current conditions.

Master thesis Energy centre - selected parts of building technology project is solving problems connected with technological issues from the construction work supplier point of view. This thesis concerns such a parts as financial, timing and preparations are. Material used as a base was a master thesis of the student from Civil engineering department.

På grund av den pågående globala uppvärmningen och den ökademedvetenheten om människans miljöpåverkan har intresset för attbygga hållbart skjutit i höjden, såväl hos stora byggföretag som hosprivatpersoner. Studien undersöker om det på ett enkelt sett går attkonstruera ett attefallshus som uppfyller kraven för passivhus,FEBY guld, och samtidigt gör det lönsamt i längden. Attefallshusetsom studien utgår ifrån är tänkt att användas som ett fritidshusoch huset är tänkt att sedan uppföras i verkligheten. Tre olikabyggnader kommer konstrueras och beräknas för att sedanjämföras. Hus A kommer konstrueras enligt minimikraven i PBLoch BBR, medan hus B utgår från samma stomme men som medhjälp av ökad isolering ska försöka uppnå FEBY guld. Det tredjehuset, hus C, konstrueras som ett mellanting mellan de tidigarehusen för att se hur lönsamheten förändras med ökadenergieffektivitet. De ökade byggkostnaderna jämfördes sedanmed den minskade energiförbrukningen för att se vilket alternativsom var mest lönsamt. Resultatet landade i att det inte var möjligtatt uppfylla de hårda krav som råder för att certifiera enligt FEBYguld med utgångspunkt i hus A. Val av uppvärmningssystem, elelement,och val av fönster och dess storlek gjorde det helt omöjligtatt uppnå den låga årsenergiförbrukning som krävs på 26 kWh/m2.Vid jämförelse mellan hus A och C blev den sistnämnda mestlönsam, med ca 32 000 kr marginal efter 50 år. Slutsatsen som kandras av studien är att det krävs ingående förändringar i enkonstruktion för att uppnå denna miljöcertifiering och för ett sålitet hus som ett attefallshus är det ännu svårare, tillsammans medatt energipriset påverkar lönsamheten i stor utsträckning. Det hadevarit intressant att i framtiden undersöka om det finns någonannan lämplig miljöcertifiering för små fritidshus somprivatpersoner kan ha att sträva mot. / Because of the ongoing global warming and the increasedawareness of the human impact on the climate, the interest inbuilding more sustainably has become enormous, among bigconstruction companies as well as civilians. This study examines ifthere are any easy ways to construct an attefallshouse that meet therequirements for passive house, according to FEBY gold, and at thesame time makes it profitable in the long run. The house used inthis study will be used as a holiday house and will hopefully bebuilt in real life, eventually. House A was constructed according tothe minimum requirements according to PBL and BBR, whilehouse B used the same frame but in addition there was addedmore insulation to meet the requirements in FEBY gold. The thirdhouse, house C, also used the same frame but was constructed tobecome a house in between the two others to see how theeconomical part would change with increased energymanagement. The higher building costs was then compared to thedecreased energy consumption to see which alternative thatwas most profitable. The result showed that it was not possible tomeet the requirements in FEBY gold if you used house A as astarting model. The choice of heating system, electrical elements,and the choice of windows and its size, made it impossible toachieve the extremely low energy consumption that was needed,26 kWh/m2. When house A and house C were compared it showedthat the last one was the most beneficial house purelyeconomically, it was approximately 32 000 SEK cheaper than houseA over 50 years.. The conclusion that can be drawn from this studyis that there will need to be big changes in a construction of ahouse to achieve this high passive house status. The small size ofthis attefallshouse and the chosen heating system for this realestate made it even harder. It would be interesting in the future tosee if there are other environmental certification that could be moreusable for small holiday houses that civilians could strive towards. / <p>2022-06-22</p>
