The aim of this diploma thesis is trying to solve difficulties connected with administrative buildings. In this thesis we are talking about possibility that administrative building can have low energy footprint. Most of energy consumption of administrative building is not created by heating but mostly by cooling and by consumption of office equipment. That is why there have been used modern equipment of the building as well as automatic control of building equipment.

The aim of this thesis is to elaborate project documentation for new construction of low-energy residential building with 16 luxury apartments, apartment without barriers and with pharmacy of basic type. It is a four-storey detached building without basement, with flat roof, roof terraces and with balconies. Residential building is located in one of the most enjoyable parts of the city of Zlín – Jižní Svahy II in the vicinity of Central park with bicycle path and with beautiful view of the Zlín. The building will be located on land plot No. 2144/46, where is still situated unfinished building "Torso" from the late 80 years. The residential building is designed in brick system Heluz, ceiling construction is made up of prestressed hollow core slabs, perimeter walls are with external thermal insulation composite system and external doors and windows are made of plastic and aluminum with triple glazing. For heating and water heating will be utilized renewables energy, such as heat pump and solar collectors. Residential units with three residential rooms are designed with a forced ventilation by means of ventilation units with heat recovery. The building also uses modern shielding elements such as outdoor blinds and horizontal sun breakers. The part of the project are also disposition studies, seminar work and energy part.

Thesis on "Planetarium with coffee" is processed in the form of project documentation for construction. The proposed facility is designed as a two-storeyed without basement with the main ground plan dimensions of 52,8 x 27,47 m and is located near the village Lošov close to Olomouc. The building is operationally divided into a part intended for public entrance and a part for operation and maintenance. Loadbearing structural system is reinforced concrete monolithic skeleton based on monolithic reinforced concrete foundation footings. Ceiling structure consists of reinforced concrete, monolithic, locally supported, cross reinforced floor slab. Vertical external walls are made of ceramic blocks with contact thermal insulation system. Part of the front rounded facade is designed as glass fronted. The building is covered by a warm flat roof. Roof cladding consists of vegetation layers, walkable terrace or non-walkable structure of roof cladding. The planetarium itself is covered by a reinforced concrete dome with a thermal insulation layer of plates of foamed glass. Fillings of doors and windows are made of aluminum profiles with isolating triple glazing. The building meets the requirements for barrier-free use of buildings.

The goal of the thesis is firstly to get all the information about the initial state of solved block of flats, which is located on the street Merhautova 76/954 in Brno – Černá pole, in terms of constructions, energy consumption and initial state of heating system. In the second part of the thesis, where are discussed the possibilities of reduction of energy consumption, variant drafts of reduction of energy consumption and their financial costs and the choice of optimal variant. Third part deals with assement of solved block of flats in terms of sustainable built environment by using tool to rate buildings in terms of sustainable built environment - SBToolCZ, evaluation of possibility to use renewables. In the end are written summaries and recommendations.
