Environment-Friendly Housing in Rural Areas
Čáslava, Petr ; RNDr.Jiří Svoboda,CSc.,DSc. (referee) ; Hudec, Mojmír (referee) ; Gaillyová, Yvonna (referee) ; Urbášková, Hana (advisor)
While I spent 7 years of study, experience and dedication to this work, the building construction has passed evolution from construction boom to contemporary building crisis. Demand for cheap building construction, materials and family housing increased sharply. Energy prices are rising every year... It seems that we will all have to deal with our essential task today or in the near future . This task is mean to prevent the current rate of degradation and destruction of our planet's climate and our environment. In this point of view, it looks the question of energy-saving construction very topical. By entering the study was to examine the possibilities of environmental friendly housing in rural areas in terms of environmental issues. My hypothesis was if can I determine the suitable candidate for the construction of passive houses themselves by comparing their characteristic of pre-defined construction samples. My objective is to offer builders and designers overview of suitable building systems with the possibility to compare the various factors influencing the decision on the selection of a builder´s construction for a house. The thesis presents the comparison of seven structural systems as a basic element of architecture. In the implementation of energy-efficient house is an architectural form often conditioned by structure. For this reason it is necessary to offer this kind of overview with options and parameters of individual building systems, which can then be used by architect to design a house for the builder - free and easy realization of his own, let´s say DIY (do it yourself). For builders (mean investors) of DIY houses is economy and finance a crucial question, therefore, for this reason I will evaluate suitable building system which is relative performance vs. price in the end. It is necessary to take into account the architecture of the house and especially the space layout and design and the attitude with the context of the rural areas environment. My pupose was to prove that good architectural design can be used with of low-cost, energy-saving and environmental friendly house built in DIY way.

Multi-purpose Building, Jana Babaka, Brno
Kolářová, Eva ; Jelínek, Petr (referee) ; Kolář, Radim (advisor)
Project's goal is to test the large buildings' design options in regards to permanently sustainable construction. The author's aim is to design energy efficient multipurpose building, with minimal negative effects on environment. The positive impact on environment is visible on the preference of natural materials used in construction. External constructions of thermal conductivity coefficient at the level of passive standard are designed using objects of renewable energy. The location in Brno has been chosen for the proposed building, specifically the location known as brownfields. Lot is accessible from the street of Jan Babak, where public transport is available. The shape of the lot is in the form of incomplete oval with internal open atrium. The administrative part of the building takes half of the area with the rest of the area being used for other businesses, such as fitness centre and restaurant. Garages are proposed to be located underneath the main building, which is built on rigid structure. This rigid structure is a steel skeleton one with linked ceilings. The foundation of building is on stilt. The roof is of a flat type with variable slope, its structure and slope are of metal construction. Claddings are designed in the form of wooden structure filled with straw bales, the exterior is thermally insulated using fibreboard thermal insulation. Inner tract facade is proposed to be panelled with wooden planks. Photovoltaic panels will be placed both from the south and southeast of the outer oval. The rest of the facade will be panelled with grate for creepers. Only environment-friendly sources of energy are considered for the proposed building. Heating and cooling is based on the heat pump air-water system; using the rainwater as an example of renewing natural energy. The surroundings of the building are designed as meadows for of infiltration of rainwater. The proposed building has been assessed in terms of environmental sustainabilit

Designing an environmentally advanced building
Dubisová, Daniela ; Vyhlídalová, Karolína (referee) ; Horák, Petr (advisor)
The goal of the master project is to design the reconstruction of an environmentally advanced building. The building is of administrative character with a multifunctional part on the first floor. It has four floors. The first two floors will be used as a co-working space and the other two can be rented to a permanent company. There is also a conference room in the building. The work is divided into three parts. The first part deals with the architectural and structural design along with the fire safety design of the buildings. The reconstructed building has a reinforced concrete existing bearing system, which remains unchanged and will be supplemented with a cavity block masonry cladding with insulation. A vegetated roof is proposed. The second part deals with the concept of the building environment technology. Retention tanks are designed with usage of rainwater for flushing system in the first two floors. A total of 112 photovoltaic panels will be placed on the roof. Air-conditioning is designed in all zones of the building, cooling is in the multifunction room and the administration room. The chosen heat source is a hot water pipeline because of the close distance from the supplier Teplárny Brno, a.s part Špitálka. LED lighting is designed in selected rooms. The third part consists of the assessment of various options for modification of the building cladding constructions with the aim of better thermal insulation capabilities. Four methods and their combinations are considered. Based on certain factors, it is evaluated which methods are recommended for the building.

Evaluation of the state and protection of environment in the Czech Republic – August/September 2023
Kyselá, Monika
The CVVM SOÚ AV ČR surveyed the environmental topics in the period from August to September 2023. Respondents were asked how satisfied or dissatisfied they were with the condition of the environment in the Czech Republic generally and in their place of residence. They were also asked to evaluate the situation in relation to various activities or facts that have an impact on the state of the environment.\n\nIn regard to the state of the environment, respondents rate the environment in their place of residence (79%) better than the overall state of the environment in the Czech Republic (72%), while satisfaction with the state of the environment in their place of residence and the Czech Republic as a whole has declined slightly year-on-year.\n\nThe most problematic perception is the traffic density in the place of residence. A majority of citizens are dissatisfied with the traffic situation in their place of residence (56%).\n\nOn the other hand, citizens are most satisfied in the long term with the availability of wildlife in their place of residence, with which more than four-fifths of them are satisfied according to the current survey (81%); three-quarters are also satisfied with the quality of drinking water (75%).\n\nWith the exception of the quality of drinking water, people living in rural areas are more satisfied with all areas of the environment in their place of residence compared to urban respondents. In contrast, people from the suburbs of large cities are significantly most satisfied with the quality of drinking water, followed by people from villages. The biggest differences in favour of villages over cities are observed in the case of light pollution, air cleanliness and cleanliness of the surrounding nature.
