This thesis deals with the calculation of the potential of the solar energy using the data from airborne laser scanning and the digital surface modelling. The situational model has been set up for Vrbno pod Pradědem town lying at foothills of Jeseníky mountains in Moravian-Silesian Region. The aims of the thesis are by ArcGis measure the surface of the roofs suitable for installation of solar panels, our value of solar radiation and calculate the potential nominal power of that installation .Then find out how much of the surface of the agricultural land would take up a solar power plant with the same nominal power.

The purpose of this Master thesis is to evaluate the possibility of use of autonomous solar systems in projects of development aid. In the first part of the thesis there is a literary review which defines the basic context of development aid, the characteristics of solar systems and the possibility of use for energy security. Another part describes a model project in which the attention is focused on autonomous solar systems and defining the criteria for evaluating the appropriateness of their use. The next step is a multi-criteria analysis using expert evaluation criteria. It also evaluates the economic effectiveness of alternative variants of solar systems and risk analysis. In conclusion, the results obtained are discussed and recommendations are suggested.

The thesis deals with the evaluation of thermal properties of buildings and their possible improvement. The work includes a summary of the different types of materials used in construction and insulation to minimize heat losses through transmission. Work involves the calculation of heat loss of the house, alternative solutions to improve its thermal properties and compared concept solutions with modern construction. At the end of the work.is peformed comparison of the existing building with the proposed alternatives for improvement.

This thesis deals with the problems of insulating older buildings. The goal of this work is to evaluate the conditions of interior environement of stables for breeding hens and to propose an improvement of its thermal properties. The first chapter describes findings from literature about individual methods of insulating buildings. The second chapter describes the basic methodology and the principle of used measurements of the technical properties of the stable for breeding hens. In the third chapter there are evaluations of the measurements and necessary calculations for the improvement of thermal properties of the building. The last chapter lists the economic evaluation of the proposed insulation method of the building in respect to the egg production and feed consumption.

Thesis is focused on the measurement and evaluation of microclimate parameters in barns for dairy farming and the determination of the energy consumptions of selected technologies in these barns. The aim of this work was to design and eventually to implement adjustments in order to improve the parameters of cowshed microclimate and reducing the energy consumption of selected technologies in depends on results of the measurements. Three structurally different cowsheds with different slurry clearing technologies were selected for monitoring. I focused on the measurement of temperature and relative humidity in relation to temperature- humidity index and its impact on heat stress on dairy cows. I measured airflow in the cowsheds and I determinate concentrations and emissions of ammonia and methane in the cowsheds in different seasons. I monitored light intensity in the cowsheds and I determined the dependence of building solutions on the use of outdoor light to illuminate the interior of the barns. The energy consumption of the lighting system depending on the season and the consumption of additional fans on the air temperature were studied. On the bases of results of the experimental part I designed and implemented lighting system, controlled by light intensity in a cowshed and energy-saving ventilation in the cowshed - type K105. I suggested a system of continuously monitoring of climatic parameters in the cowshed with immediate calculation of temperature- humidity index. Measurements have shown the dependence of gases concentrations on the way of slurry clearing technologies. The building solutions of cowsheds and type of ventilation proved a significant influence on the temperature- humidity index during the summer.

The thesis intends to create a basis for deciding the efficiency of implementation of saving measures meaning thermal insulation of buildings and for defining their benefits. This study is made on two typical objects demonstrates a development of requirements for thermal properties of the building construction and evaluates a possibility and suitability of using of different insulation methods. It proposes acts to meet current thermal engineering requirements. Performing the calculation of unit prices are counted implementation costs and return of investments for additional measures. The thesis gives investors a source material for their investment plan for buildings thermal rehabilitation and assesses the benefits.

The thesis is focused on renewable energy, respectively biogas plants. In a literature part of this work there are described renewable resources used in the Czech Republic. There is also described the issue of biogas plants including their benefits for the region. The practical part is focused on one of the products of biogas plants, that is fermentation residue - digestate. In this part are presented the results of one year pot trial in which were observed the positive effects of digestate fertilizer on yield and quality parameters of selected species of vegetables - kohlrabi.

Aim of this Thesis is to Evaluate the Effectiveness of investment Projects selected business Entity. To assess the Effectiveness of the Methods used for static and dynamic. Greater Emphasis is placed on dynamic Methods, which, in their Calculations take into account the Time Factor. On the basis of partial Results and Calculations are made businesses recommendation whether to implement the Investment. An important Element is the identification of Risks and risk analysis that may have on the efficiency of investment Projects substantial influence.
