Building services of near zero energy buildings
Šťastný, Radek ; Tůmová, Eliška (referee) ; Hirš, Jiří (advisor)
Master´s thesis is focusing on zero energy building with technical equipment. The building was built in 70. decade of last century. It has been using for sport and cultular events until these days. Restaurant was connected to sport hall. First part is focusing on zero energy building and technical equipment, their using, combination and optimal connecting in systém. Second part solving how many fotovoltaic panels must be in the system to reching economic advantage. In third part is solving how to connecting fotovoltaic panels to the system.

Timber and internal environment of buildings
Buchta, Stanislav ; Drápal,, Radim (referee) ; Vaverka,, Jiří (referee) ; Kabele,, Karel (referee) ; Hirš, Jiří (advisor)
The present doctoral thesis engages in an internal environment of wooden buildings. Currently, the specialists endeavour to design and realize this type of buildings as low-energy consuming. In an effort, they minimize the thermal losses by reduction of heat transfer coefficient of external walls and reduction or elimination of their air permeability. Not always structural and technical requirements of this kind of buildings are satisfied and also a sanitary and health protection is not fully sustained. Increase in a relative air humidity of internal environment has a negative impact on moisture in wood and heat insulation in the structure. Then the buildings are exposed to the increased risk of mold infestation. This can cause various health problems such as headache, respiratory diseases, general fatigue or impaired concentration. For the purpose of experimental verification of the internal environment, four wooden houses of medium size were observed in 2010 and 2011. The internal temperature and humidity as well as subjective feelings of the household members were monitored there. For the simulation of the real wooden construction, an application BSim was used. Different states as well as stationary and nonstationary physical processes were simulated by the boundary conditions adjustment. Also the criteria for designing and optimization of living comfort of household members were recommended in the thesis.

Ventilation and Air Conditioning of Civil Buildings
Matějíček, Michal ; Adam, Pavel (referee) ; Hirš, Jiří (advisor)
This bachelor thesis deals with the design of the air conditioning of a swimming pool in Karlova Studánka. Air conditioning ensures forced ventilation and adjusts incoming air to required temperature and humidity inside the pool. The theoretical part deals with literary research on the topic of humid air, evaporation from the water and the thermal load of the object. The experimental part deals with evaluation of the measured humidity and indoor temperature in a bathroom and in a swimming pool.

Energy assesment of single family house
Panovec, Jan ; Počinková,, Marcela (referee) ; Hirš, Jiří (advisor)
The aim of this bachelor’s thesis is to understand the nature of the energy assesment of building with low energy demand and energy-saving requirements. The calculations of energy intensity and experimental measurements of chosen parameters of inner microclimate in the building were done. Theoretical part includes requirements and principles of projecting buildings with low energy demand.

Measurements of selected parameters of the building services systems and indoor environment of buildings
Malach, Tomáš ; Rubinová, Olga (referee) ; Hirš, Jiří (advisor)
In the first part, the bachelor thesis deals with indoor environment of buildings, solar irradiance and thermography. The measuring device for measuring the energy flows of the building, climatic data and microclimate variables are presented in this part. In the next part, I mention the principles for the measurement thermal imaging camera and I evaluate thermal images. I specify measurement of the hygrothermal microclimate, carbon dioxide concentration and climate data for power engineering. Analysis of measurement of the selected parameters is performed simultaneously and their graphical processing. In the last part, I apply measurement on the real objects, I analyzes the measured data (air temperature, relative humidity and the concentration of carbon dioxide in the room) and I perform their evaluation. At the end, I evaluate the outdoor air temperature and theirs effect for design heating and cooling systems.

The application of renewable energy in buildings
Panovec, Jan ; Formánek, Marian (referee) ; Hirš, Jiří (advisor)
The aim of this diploma thesis is to understand the functioning of heating and cooling systems in an administrative building built in passive standard using a renewable energy source. The thesis includes theoretical findings of heat pumps and designing the heating systems. The experimental part contains an analysis of working of heating and cooling systems in selected rooms in assigned building, which includes an experimental measurement of selected quantities and a thermographic measurement. In the last part of the thesis a comparison of measured and simulated values using simulation software was done.

Energy assessment of buildings
Velísková, Eva ; Maurerová, Lenka (referee) ; Hirš, Jiří (advisor)
The master’s thesis deals with energy assessment of buildings according to a current valid legislature. In the first part the energy assessments problems are solved. The next part solves the energy concept of the educational building, Pavilion P4, AdMaS centre of Faculty of Civil Engineering of BUT, in the form of project documentation. In the part of thesis there is a simulation characterizing dynamic behavior of building. The thesis point is the evaluation of energy balance and a draft of measures leading to the power consumption decrease.

Analysis of influence of a roof construction on indoor thermal stability in summer season
Hofman, Petr ; Katunský,, Dušan (referee) ; Hirš, Jiří (referee) ; Mohelníková, Jitka (advisor)
The design of the building must respect the basic conditions for ensuring thermal comfort in the living space. The thermal comfort is influenced by several factors and one of them are the constructions of the building envelope. This work was focused on investigating influence of roof structures. The goal was to make analysis of influencing the selected modifications of the roof compositions to the thermal stability in the summer formed by experiments and detailed computer simulations. On the basis of these findings were defined suitable modifications. It has been worked out that the maximum indoor air temperature can be reduced by up to 1.5 °C in a suitable way. The cool roofs, thermal inertia and the ventilated air cavity layer have the greatest benefit. When evaluating the return on investment in a roof with high thermal inertia represented by a concrete layer of 100 mm, its return compared to a light roof and airconditioning is 12.1 years. The return on installation of external blinds on roof windows is 3.3 years compared to airconditioning.

Energy assessment of building
Žůrek, Petr ; Horák, Petr (referee) ; Hirš, Jiří (advisor)
In this bachelor´s thesis are summarized the most important changes of energy asessment of building that brought novel of law 406/2000 Sb. about energy management in 2012. There are also stated requirements of legislation EU on the energy asessment of building and form to use in Czech republic. The aim of the bachelor thesis is also analysis available conducting decrees for laws and how will it effect projection and technical practise. In second part there is the energy asessment and energy audit of block of flats.
