This graduation theses contains the solution of new multifunctional building. The house includes a one underground and three above-ground floore with a flat roof. Project contains architectonical and engineering solution, constructive (statics) part and sanitary, technical installations.

Master´s thesis is about hot water distribution with using of heating cables. This work is divided into three parts. First part is main function of heating cables, second part is about solution and suggestion of water supply, including hot water heater in two different objects. Important thing is difference a variant of the heating cable and without it. The last part is experimental, whose task is to verify the properties of the cable.

The diploma thesis deals with the problematics of both health and technical installations in a residential building in the city of Brno. The theoretical part deals with the analysis of the topic with particular focus on the problematics of thermal losses within the pipeline. The thesis also focuses on various possibilities of protection of the pipeline and reduction of the thermal losses. The project part of the thesis deals with both health and technical installations in the particular building within the chosen option. The concerned building is constructed in the form of cascades consisting of five floors above the ground level and one underground floor which serves as a parking lot for the cars of the building residents.

This thesis deals with health - technical and gas pipeline installations in the industrial hall. The building is situated in Frydek Mistek. The theoretical part compares the applicable technical rules for gas in Slovakia and the Czech Republic. The work also deals with the issue of determining the size of the reservoir water heater in several variants and compared to surveys by the use of hot water in similar objects. The design part is then developed addressing health - technical and gas pipeline installation for the specified object of the industrial hall.

Modern energy saving technologies are become increasingly mature, easier to implement and financially profitable. Both the European Union and the Swedish government have directives with goals regarding energy savings for the year 2020 and 2030. Here, making buildings more energy efficient plays a large role as around 40% of the total energy usage in Europe can be related to buildings. Constructing new, nearly zero energy houses is currently very popular, but as a vast majority of all buildings in a country like Sweden are older buildings, built before 1980, a majority of the used energy will come from these buildings. Hence, there is plenty of incentive for carrying out energy saving actions and investments in older buildings. From previous research and interviews with energy consultants, it can be concluded that energy saving actions are not being carried to the extent that is possible. This thesis aims to find out why this is and mainly what the main obstacles are when implementing energy saving solutions in older buildings. A case study, consisting of eight interviews with energy consultants and real estate owners was carried out in order to get an understanding of the current situation and the different stakeholders views on this issue. The results showed that, at least in the represented cases, there is a will among real estate owners for moving forward with energy saving. An understanding has also recently emerged where most real estate owners realize that there are great financial incentives connected to implementing energy saving solutions to current, older buildings. However, increased will of making a change has not yet resulted in a majority of buildings having installed energy saving solutions. One factor for this is that each building is its own individual case and therefore needs to be handled individually due to different conditions and are therefore suitable for different energy saving actions. Other factors include lack of technical and financial understanding among some real estate owners, slow decision making processes and ownership types. The research explores theories related to decision makings to provide a comprehensive overview regarding the current situation of energy saving in Sweden, as well as a contribution to the theoretical literature regarding decision making / Modern teknik inom energibesparing blir allt mer mognare, lättare att implementera och finansiellt lönsamt. Både den europeiska unionen och den svenska regeringen har direktiv med mål för energibesparing för år 2020 och 2030. Här spelar byggnader en viktig roll, då byggnader står för ca 40 % av den totala energianvändningen i Europa. Att bygga nya, nära noll energi byggnader är för närvarande väldigt populärt. Men i ett land som Sverige, där majoriteten av alla byggnader är äldre byggnader, kommer majoriteten av energianvändningen fortfarande från dessa. Därav finns det stora incitament till att genomföra energieffektiviserande åtgärder på äldre byggnader i Sverige. Från tidigare studier och intervjuer med energikonsulter kan det fastslås att energibesparande åtgärder ej genomförs i den grad som det är möjligt. Målet med denna rapport är att utröna varför det är så samt vilka huvudsakliga hinder som kan relateras till energibesparing i äldre byggnader. För att få en överblick av den befintliga situationen samt hur olika intressenter ser på denna fråga genomfördes en fallstudie bestående av åtta intervjuer med energikonsulter och fastighetsägare. Resultaten från studien pekade på att det finns en vilja bland fastighetsägare att gå vidare med energibesparande åtgärder. På senare tid har även en förståelse vuxit fram bland fastighetsägare där man inser att det även finns stora finansiella incitament med att implementera energibesparande åtgärder på äldre byggnader. Detta har dock ännu ej lett till att energibesparande åtgärder genomförts på en majoritet av befintliga byggnader. En anledning till detta är att varje byggnad måste hanteras individuellt då alla har olika förutsättningar och därmed lämpar sig för olika energibesparande lösningar. Andra faktorer inkluderar teknisk och ekonomisk kunskapsbrist bland vissa fastighetsägare, långsamma beslutsprocesser och ägarstrukturer. Studien nyttjar teorier relaterade till beslutsfattning för att ge läsaren en överblick av den befintliga situationen kring energibesparing i Sverige. I tillägg bidrar studien till den teoretiska litteraturen om beslutsfattning.
