Energy efficient building of cinema and gallery
Kučírek, Pavel ; Jelínek, Ondřej (referee) ; Blasinski, Petr (advisor)
The aim of the master project is to design a new building of the cinema with gallery and to design technical equipment. The building is „L“ shaped, the half of the building is single-storey and the other half is two-storey, there is no basement. The most important rooms are on the ground floor – gallery, cinema, foyer and staff rooms. On the second floor there is projector room, sound engineer room, recording room and other sound adjusting rooms. The vertical loadbearing and non-loadbearing walls are designed from aerated concrete blocks, horizontal structure are cast-in-place reinforced slabs, the roof is flat. There is a reinforced concrete staircase that leads to the second floor, the building is insulated by ETICS. There are 4 HVAC units designed in the building, units are controlled with monitoring and controlling unit, also there are photovoltaics and rainwater storage systems designed. The project and visualizations were made in the ArchiCAD, MS excel, DEK, Halton HIT, AeroCAD software. Experiment validates measured data with mathematical analytics model that I used in 7 theoretical models of ventilator controlling possibilities to achieve energy savings. Re-sults will be compared and assessed.

Carbon sequestration by forest ecosystems in canging climate.
Hlaváčková, Lucie ; Lhotáková, Zuzana (advisor) ; Urban, Otmar (referee)
The global carbon cycle is in the focus of the scientists' interest, because understanding carbon sinks and their relationships can show the solutions of problems related with increasing CO2 concentration in the atmosphere in the future. I focused on the role of forests ecosystems in this carbon cycle. All forests cover almost one third of the Earth's land area. By photosynthesis they bind big part of atmospheric carbon to their biomass. Sink strength of forest can differ according to the type of biome, forest stand age and actual climatic conditions. Forest biomes can be generally divided according to the latitude to three groups: tropical forest biomes, temperate forests and boreal forests. The size of carbon stock decreases in this order. Other parameters, such as net primary production and respiration differ in dependence on the particular ecosystem. Tropical rain forests represent great carbon stock, but their deforestation causes massive C emissions back to the atmosphere. Boreal forests aren't considered as important carbon sink, but they influence local climate. Some speculations can also appear about the old forests. It is possible to find authors, who claims, that old forests are no more carbon sinks, so that their carbon balance is neutral. Many surveys prove that they bind less carbon...

Mesophyll CO2 conductance in consequence with the leaf anatomy and environmental factors.
Malcová, Kateřina ; Lhotáková, Zuzana (advisor) ; Nátr, Lubomír (referee)
The CO2 diffusion pathway from the atmosphere surrounding the leaf to the chloroplast stroma is composed of several parts, where each part poses certain resistance to the CO2 flux. The CO2 diffusion from the sub-stomatal cavities to the stroma is limited due to mesophyll conductance (gm), which includes CO2 movement in gas, liquid and lipid phases. The mesophyll conductance is influenced by factors that are both internal (e.g. leaf anatomy and leaf age) and external (e.g. irradiance, temperature). Internal factors exhibit rather long-term responses of gm, while external factors are involved in short-term changes. For these rapid changes are probably responsible aquaporins. gm significantly influences the rate of net photosynthesis, almost in the same range as a stomatal conductance does. The limitation of photosynthesis given by mesophyll conductance is not fixed and varies among species and plant functional groups. Due to continual increase of CO2 concentration in the atmosphere, variability in gm can lead to enhanced competitive potencial of some plant species.

How and why we can estimate atmospheric CO2 concentration from stomatal density?
Horská, Jana ; Lhotáková, Zuzana (advisor) ; Kutík, Jaromír (referee)
The atmospheric carbon dioxide concentration have always been fluctuating. In the past [CO2] did not ever increase as quickly as in the last 200 years and apparently human activities such as fosil fuel burnig conribute significantly to this increase. Changes in stomatal frequency as a reaction on changes in [CO2] were observed on several species of living plants. It leads to investigation of stomatal fequency of herbarium samples and fossil plants. These estimates of stomatal frequency were consequently used to estimate levels of atmospheric [CO2] in the past. This study describes behavior of stomata in variable [CO2] and summarizes influence of environmental factors on stomatal patterning. The differences in responses between groups of plants of different evolutionary origin are considered. The advantages and disadvantages of selected stomatal parameters are discussed considering their suitability as tools for [CO2] estimate in the past.

Energy Assessment
Březina, Jan ; Maurerová, Lenka (referee) ; Horák, Petr (advisor)
The first part of the final thesis is focused on the use of thermovision for diagnosing defects and failures in building industry. Documented history, physical principles and conditions for the measuring of thermographic camera are described in this part. Thermal images of the object described below were used for demonstrating the defects. The second part is dedicated to the elaborated energy assessment for a nine-storey slab block building. In total, there are five energy economic measures developed for the building. Three of those are of structural character and two of those are for building equipment. There are two variants designed based on the measures, one of which is recommended and evalu-ated. The final section is focused on the measurement of slab block building indoor environment (CO2, air temperature, relative humidity, dew point) and its assessment in concern with the current legislation.

Energetic evaluation of civil buildings
Pliska, Roman ; Adam, Pavel (referee) ; Horák, Petr (advisor)
The first section of this thesis describes possible energy savings in family houses. Subsequently, possible energy savings are applied to, and a system revision is presented for, an office building, along with a calculation of the return on investment for the described variant based on notice 480/2012 Sb. The final section focuses on the measurement of the indoor environment at an administrative building (CO2, air temperature, relative humidity) and their assessment according to the current legislation.

Electronic instrument for environment monitoring during plants growing
Žák, Jaromír ; Kuchta, Radek (referee) ; Hubálek, Jaromír (advisor)
The main goal of this project is to make electronic instrument for monitoring environment during plants growing for Mendel University of Agriculture and Forestry in Brno. The new device will replace current analog recorder of temperature and humidity. New device will be extended by measuring atmospheric pressure, illumination and CO2 concentration. Main advantage of electronic measuring is better lucidity of gained values. New concept allows easier comparison new values with earlier measured data.
