The thesis focuses on energy savings of an apartment building. Firstly, the basic terms concerning apartment building and their costs are explained. Secondly, the thesis looks into energy efficiency of buildings, possibilities of energy savings and methods of economic evaluation of investments. The thesis sets the goal to evaluate current state of a selected apartment building from the perspective of energy efficiency and to propose possible energy saving measures. Lastly, the thesis aims to evaluate proposed measures from economic perspective and the perspective of energy efficiency.

Content of this diploma thesis is analysis of the operation of heat and cold sources and its evaluation based on data from measurement and control systém and design of a new solution for heating and cooling selected part of the object Otevřená zahrada. Building is located on the street Údolní in Brno. It is a three-storey building serving as offices of non-profit organizations and weekend activities of the organization. On the first floor there is a technical background of the building and half of it is used by four offices. On the second floor there is a seminar hall with a capacity of 50 persons. The rest of the floor is used by three meeting rooms and three offices. The third floor is used by four offices. For the heating and cooling of building, there are designed heat pumps ground-water. Air exchange in the building is provided by the air handling unit.

The diploma thesis deals with overall reduction of energy use in the family house by reducing heat loss and selecting heat and cold source. In the first part are described different types of heat loss along with ways to efectively reduce each loss. Contact insulation systems are further more described, because of beeing used more often. Newer materials are also presented to readers, although their use is less common. The next chapters describe the parameters of choosed heat and cold sources. The calculating part describes process of annual power usage calculation. Further there are three designs of thermal insulation proposed and for each one the appropriate heat and cold source is selected, using heat pump with bivalent operation for all designs. Finally these options are compared in an economic and technical way and the most advantageous of them is determined.

This master´s thesis deals with calculations of heat losses, design of ventilation and heating of a two-storey family house. Part of the thesis is the characteristics and description of the building, calculation of heat losses according to the standard ČSN EN 12831-1. Furthermore, the heating system is designed, including the choice of heat sources, calculation of underfloor heating and pressure losses. Subsequently, forced ventilation is proposed with heat recovery. The last part assesses the possibility of using a photovoltaic system for the object. Relevant technical documentation is also prepared for the proposals.

The diploma thesis deals with the design of testing equipment, a climate chamber in particular, to simulate external weather conditions. The chamber walls are made of socalled sandwich insulation panels. Based on the wall thermal properties, heat loss of the chamber was calculated. The conditioned air is supplied by a distribution channel at sides of the chamber. The exhaust air leaves the chamber in the ceiling zone. The ventilation unit is located on the ceiling. The design includes the integration of the UV lamp, simulating sunlight. The chamber will allow the weather effects on the microclimate inside a car to be studied. Furthermore, the sunlight simulations can be carried out in the chamber to detect polymers or varnish aging, and the fading of colours.

This thesis deals with the heat loss and the heat loads simulation of A1 building in the area of The Faculty of Mechanical Engineering, Brno University of Technology and with the measures of the energy saving. The measures of the thermo-technical charakteristics for the winter and summer operations are provided on the base of the current state simulation. These measures include increasing of thermal resistence (of the building case), the radiation shielding, the sun blinds and the passive cooling by the night ventilation. All the simulation are performed in TRNSYS 16.1 software.

The thesis describes the various ventilation and air conditioning systems used to maintain suitable, temperature-humidity parameters of air in office buildings. The thesis deals with their advantages and disadvantages and assessing the suitability of using several systems for the application. The main task is to choose the most suitable system and it's calculation. For the actual system design is needed to detect a heat loss and gains the specified object and calculate the minimum amount of ventilation air. There will also be given psychrometric calculation of a device and drawing documentation, including draft of an engine room.

The main goal of the submitted thesis is the design of central conditioning system used to ensure the required internal microclimate of office space and meeting rooms on the 2nd floor of office building, located in the city of Brno. The first part provides an overview of air conditioning systems and the appropriate central air conditioning system is selected. In the next part is designed the devices for air conditioning by building layout, properties of building structures, equipment and office space occupied. The work also submits drawing documentation, technical report and specification of materials used.

Diploma thesis is focused on the design and dimensioning of the central air-condition system of the offices in two-story building. The thesis consists of a theoretical part which deals with air- condition systems, and computation and design part. The computation part is comprised of calculation of quantity of ventilation air, calculation of heat losses and heat gains and psychrometric evaluation of operation during summer and winter. Design part consists of design and dimensioning of air-distriutions and air ducts and consist of design of air-conditioner and machine room. There are specification of materials and drawing documentation in the end of thesis.

The subject of this thesis is to simulate the energy balance of the two new buildings, classic brick buildings and light wood construction. On the basis of these simulations are compared effects of various parameters of insulation including panels for building openings on heat loss, energy efficiency cooling and solar gains. Energy simulations were performed with TRNSYS 16_1.
