Dissertation deals with the technical parameters of natural thermal insulation. In addition, there is a global trend in the construction of reducing energy consumption for heating, air conditioning, or with operating facilities in buildings and the use of perspective and efficient building materials with a negligible negative impact on the environment. Therefore, the attention not only professionals are increasingly turning to alternative materials, such as natural insulation, the material can be drawn from local sources and whose production is energy-saving and leaving a small ecological footprint. As part of the doctoral thesis were tested short term water absorption, measurements were made of the thermal conductivity and its change after the test short term water absorption. Was determined dependence of thermal conductivity on humidity and heat resistance was determined. Moreover a natural insulation applications in building construction with a comparison of the various technical parameters and environmental footprint. At the conclusion was made by acoustic insulation in timber construction and price analysis.

Možnosti využití bezpilotních prostředků při hodnocení efektivity zateplení budov zemědělského charakteru
Čubík, Josef
The bachelor thesis deals with the measurement of heat leakage in agricultural buildings. Depending on the dimensions of these buildings, it is necessary to consider how to improve the assessment of their heat losses. The most used technology for measuring heat leakage is by using handheld thermal cameras. Considering the large areas and the time required, it is suggested to use an unmanned vehicle with suitable characteristics for this task. However, the measurements were done using a thermal imaging camera, which led to selecting an area under which conditions it is more efficient to use a drone. The difference between internal and external temperatures is essential for a conclusive measurement. Therefore, sheds requiring higher temperatures designed for chicken fattening, were chosen for the experiment. The result showed that heat leakage is a significant problem. All the buildings investigated showed heat loss. The leakage varied depending on the specific type of hall measured and the insulation used. Losses were particularly evident in older buildings with leaks and exposed structural construction. Leakages were mainly in the form of significant thermal bridges.
