This master’s thesis is dealing with the plan of reconstruction of the house in an effort to get closer to "near zero building". Total heat loss along with calculation of the cost of the house operation and the energy performance of buildings were computed for the given house. Then we have enclosed suggestions of individual methods of building´s insulation (replacing of windows, doors and gates, insulation of exterior walls, roof and ceiling between floor and attic) and a draft of a new technical building services (forced ventilation with heat recovery, photovoltaic system and heat pump). Furthermore, the suitability of the original heating system was evaluated and the also the energy performance for the renovated building was analyzed during the reconstruction. An economic evaluation was calculated for each method of reconstruction, together with the new green subsidy programme. At the end of the dissertation is drawn up the economic evaluation of the whole proposed reconstruction, together with an assessment, what class of the building we have achieved according to its the energy intensity.

The presented diploma thesis analyses the possibilities of determining the carbon footprint in relation to the production unit of the budget indicator. The theoretical part of the thesis describes the basic concepts associated with the carbon footprint and construction industry. The aim of this thesis is to quantify the carbon footprint of construction process, mainly during the production phase, and to compare the carbon footprint of objects of different production technology. The main output is the determination of an average carbon footprint converted to a unit of the budget indicator.

Diploma Thesis „Polyfunctional building“. The work deals implementation project of polyfunctional building in Jihlava. Object is situated on Jihlava suburb in emerging part called „Horní Kosov“. Land is gently sloping from west to east. It continues for Buková street. The building has six floors and a basement. The basement is made from monolithic reinforced concrete. It is used as garages. Floors are made of ceramic bricks with isolation . First floor contains four commercial premises and main entry for housing part. Seventeen flats are situated from second to sixth floor. Sizes of apartments are 1+kitchen corner to 4+kitchen corner with terraces and balcony. Roofing is solved with simple flat roof. Heating will be ensured with central heating. Every apartment, commercial premises, shared premises are going to have it’s own gas boiler. Polyfunctional building is connected on a local road – Buková street, which is connected to new communication. Within multifunctional building twenty parking slots is designed at the basement. Next fourteen parking slots is designed outside.

The thesis aims to propose a system for heating and hot water for a family house, according to drawings supplied by the building architect. At the request of the investor as the primary object will be considered a variant of underfloor heating. For comparing the heat loss, economic and possibly to State subsidies system selected will be processed by an alternative option to the ventilation air heating. Underfloor heating and hot air are among the low-temperature heating system, which can use low temperature heat sources, such as heat pumps. This assumption corresponds to investor requests, the source of heat in a family house with a heat pump and gas boiler. For hot water will be used as an alternative to a fireplace in the living room. To use the results of the thesis is to calculate the heat loss and heat, according to current standards include design and hot-water heating system including hot-drawing documentation. Finally, the economic evaluation of different alternatives in terms of investment and operating costs.

Master´s thesis deals with an assessment of investment return in saving precurations. The issue is used on an ordinary detached family house. The assessment is done in more variants to reach an objective comparison of the most advantageous investments. In the first part there is a comprehensive theory explaining the connections of the procedures and the algorithms of the calculations. The second part is calculation, especially from the thermal engineering, energy rating of buildings and the economic return on investment. The third part is an evaluation which, on the basis of the experiences and the results from the thesis, offers a proces show to think in case of intended reconstruction and how to evaluate the efficiency of the investments in the saving precurations.

Diploma thesis deals with comparing of current awards by Classification of building structures and works and awards by Functional parts. It is possible to calculate Building life cycle costs by Functional parts. This is definately the advantage of the system because the calculation cannot be done by Classification of building structures and works. A new law on public procurement deals with Building life cycle costs as an evaluation criterion. So it is recommended to use Functional parts awards. The other goal of the thesis is to find bridges between Functional parts and the issue of BIM. BIM is a trend of global construction industry.
