Residential Building Renovation
Horn, Jiří ; Stránská, Zuzana (referee) ; Struhala, Karel (advisor)
The aim of this diploma thesis is a renovation of a two-story family house in Dolní Krupá. The original house is from 1935. It has several newer outbuildings such as garage or storage spaces. The walls are made of solid fired bricks. There is a timber joist floor structure. The main building has a gable roof with timber roof truss. The outbuildings have flat and mono-pitched roofs. The reason for the renovation is the inefficiency of the aging building combined with nearing end of life of some building elements. Also, the layout of the building with multiple outbuildings built during its service life does not comply with contemporary housing standards. Therefore, a large part of the building will be demolished and replaced with new structures. Only the load-bearing walls on the first floor of the main building and the part of the building adjacent to the garage will remain. The new layout will consist of two separate apartments (one on each floor). The load-bearing structures will include ceramic masonry and reinforced concrete floor. The roof truss will be made of wood. The original appearance of the object will be preserved. The house will be heated with an air-to-water heat pump installed next to the north facade of the house. Each floor of the house will be air conditioned by a separated air conditioning unit. As the third part of the work, I chose a life cycle assessment (LCA), using several different building materials for a this renovation.
Assessment of natural and recycled materials in buildings

Life-Cycle Assessment (LCA) is an analytic method for evaluation of environmental impacts of products, services and technologies. It is associated with all the stages of a product's life. The environmental impacts are evaluated on the basis of material and energetic flows, which are in influence with the environment. These impacts are always determined in the relation with the function of the product or the service and so it is possible to compare them with the other alternatives. One of the most important reasons why I have chosen this dissertation thesis subject was the growing public interest in impacts of the building constructions on the environment and human organism. Only a few experts and scientific research centres deal with the problem of environmental impacts of the buildings in the Czech Republic so the main goal of this thesis is to help with a spreading a knowledge about it. There are four main problems to solve in the thesis: determination of environmental impacts of selected materials which are missing in available databases, creation of life cycle models of evaluated buildings, determining the most appropriate functional unit and determining the contents of the recommended LCA protocol for building analysis. In the first phase of the thesis there was built a detailed life cycle model of the reference building on the basis of available documents and databases. This "cradle to cradle" LCA model was then optimized for a large number of life cycle scenarios to determine the significance of the impact of individual variables on the overall environmental impact of the building. The knowledge gained from this analysis was applied to the lifecycle models of other buildings and then there was assembled the recommended form of the LCA protocol. In the final stage, the results of the environmental impacts were quantified on the different functional units which were used for determining the appropriate form.
Dyslipidemia of metabolic syndrome and physical activity

Objective: In obese patients, we hypothesized physical exercise (PE) to affect lipids rather through its intrahepatic fat accumulation-lowering effect, associated with a decrease of total body fat (Fat%) and even weight (Mass), than through muscle work and an improvement of physical fitness. Design and setting: Thirty seven sedentary, non-diabetic women (BMI median 34.8 kg/m2) from our out- patient department were tested. Elimination criteria: recent weight reduction, lipid-influencing or heart rate-modifying medication. Interventions: PE protocol: 60 min supervised trainings, intensity at 65% of VO2max, modified by the Clamped Heart Rate test. Median (M) of total training hours was 34 during 115 days . Main Outcome Measurements: an effect of PE on total cholesterol (CH), triacylglycerols, HDL- cholesterol (HDL-C), LDL-cholesterol (LDL-C), index of atherogenity (IA), atherogenic index of plasma (AIP), maximum peak oxygen consumption (VO2max), Mass, body mass index (BMI), waist circumference (Waist) and Fat%. Results: Statistically significant differences at start (_s) and at the end (_e) of PE (p<0.05): AIP -0.049, Mass -3.6 (kg), BMI -1.7 (kg/m2), Waist -2.5 (cm), Fat% -2.5, VO2max 2.92 (l.min-1.kg-1), W 16.4 (Watt). Correlation coefficients, Pearson's between Gaussian distributed (Gd-v) variables and...
