Comparison of land use in the municipalities of Šenčur and Vodice based on municipal spatial facts
Get PDFIn my diploma thesis are presented legislation and Landscape plans of municipality of Šenčur and\ud
municipality of Vodice begining with year 1984 until today. Through the thesis we were identifying\ud
the changes of basic land use and detailed land use for municipalities of Šenčur and Vodice. We were\ud
comparing Landscape components of long-term social plans of the municipalities (PS SDPO) and\ud
municipal spatial plans (OPN). Analysis of basic land use was made for the complete area of the\ud
municipalities of Šenčur and Vodice, detailed land use was made only for the settlements of Šenčur\ud
and Vodice. Analysis and data processing was made in program ArcGIS 10.2. The area of detailed\ud
land use for the settlements was converted to the number of residents in a settlement. All results are\ud
given in figures and maps. In both municipalities is the share of residential areas increased at the cost\ud
agricultural land
Vacuum window and the problem of anodic bonding of flexible edge seal
Get PDFThe thesis presents vacuum insulated glazing in comparison to the insulating glass unit filled with\ud
inert gas. It describes the biggest problem of vacuum insulated glazing and presents solution. The first\ud
part describes component elements of a vacuum insulated glazing and insulating glass unit. Presented\ud
are all of the modes of energy transition through the glazing unit. Using various of glazing materials,\ud
we perform the calculations of construction physical parameters of glazing units in computer program\ud
WINDOW 7.2. With the program we compare coefficient of heat transfer, the transmission of solar\ud
radiation and the transmission of light between vacuum insulated glass and insulation glass unit.\ud
Second part of the thesis presents the innovative method of flexible edge sealing for vacuum insulating\ud
glass. Flexible edge was developed in Swiss Federal Institute EMPA as a part of Winsmart project\ud
which was accepted inside the Seventh framework programme or short EP7. Today's vacuum insulated\ud
glass unit on the market contains rigid edge seal. The temperature differences between the inner and\ud
outer pane causes the problem of differential expansion of the panes, which with a large temperature\ud
differences leads to bending and also breaking vacuum insulated glass unit. Winsmart project\ud
overcomes these problems by using the flexible edge seal. The thesis contains results of various tests\ud
made by developing the method and also the problems that we encounter by anodic bonding which is\ud
crucial to the flexible edge. We made three vacuum insulating glass units containing the innovating\ud
flexible edge which are presented including with there problems and weaknesses
Behaviour of singly symmetric steel profiles subjected to compressive force
Get PDFThis Master Thesis deals with singly symmetric steel profiles subjected to compressive force. Detaily\ud
are analysed centrically and eccentrically loaded hot rolled steel elements with equal leg cross-section.\ud
The procedures for determining the buckling load for elements with a compact and slender crosssection\ud
according the European Eurocodes and American AISC standards are presented. Featured\ud
procedures are used in the calculations of buckling capacity for selected element with a slender crosssection.\ud
Influence of residual stresses and geometrical imperfections resulting from the method of\ud
manufacture of steel elements, is incorporated in buckling curves. Numerical analysis of buckling\ud
behaviour were calculated in numerical environment Abaqus. In numerical simulations material and\ud
geometric imperfections were combined in an equivalent geometric imperfection with the\ud
corresponding amplitude, so that the results of numerical simulations for centrically loaded elements\ud
with a compact cross-section coincide with the corresponding buckling curve in Eurocode standard.\ud
Adequacy of the numerical model eccentrically loaded elements was validated by comparing the\ud
results of the buckling load by the results of other researchers. The results of numerical simulations\ud
centrically and eccentrically loaded elements are further compared with the results calculated\ud
according the standards. Proposals for less complicated and more accurate calculations are given for\ud
standards
Cloth filtration on the waste water systems
Get PDFThe master's thesis is based on the executed measurements of suspended solid contents,\ud
COD contents and flows on the tested depth-cloth filtration device Mini filter 1 on WWTP\ud
Domžale-Kamnik. The measurements were carried out in the period from 03.07.2012 –\ud
20.9.2012 once a day from Monday till Friday on the tested filtration device and namely flow\ud
measurements and reading of heights in the filtration device chambers and reading of\ud
suspended solid contents (TSS) on the continuous measurement on the outflow from the\ud
secondary clarifier. Measuring of parameters TSS and COD was carried out in the\ud
laboratory.\ud
After 17th of August 2012, the testing of tested filtration device was upgraded by including the\ud
simulation of increased load with TSS on the inflow into the device. From that day on, the\ud
load with TSS on the inflow into the tested device Mini filter 1 was gradually increased. The\ud
purpose of simulation was to reach the load point with TSS where the cloth filtration device\ud
Mini filter 1 will be constantly in the procedure of cleaning or removing the captured solid\ud
particles from the filtration cloth. This point wasn't reached. Yet a minimum time during\ud
rinsing under 2 minutes was achieved. Meaning, that the device was once again in the state\ud
of cleaning less than 2 minutes. The cleaning procedure didn't affect the filtration process of\ud
inflow water
Analysis of effectiveness of the Koštabona housing estate investment project
Get PDFThis thesis provides an analysis of the investment success of a project for three residential\ud
flats built in a house in the village of Koštabona, which is located just outside the city of Koper.\ud
To begin, a description of the building is presented, which is then followed by a description of\ud
the construction costs incurred. Three calculations are then made for the building: a calculation\ud
before construction commenced, a calculation made during the construction process, and a\ud
calculation made after the construction process was completed. The last calculation represents\ud
the basis for the investor to assess the profit made. After preparing and calculating the costs\ud
incurred, the success of the project was analysed from an investment perspective in various\ud
locations within the city of Koper. This calculation allows for a comparison to be made between\ud
the cost of constructing similar buildings and their sales price in different locations. We selected\ud
four locations: the first in Koper, the second on the outskirts of Koper, the third in Koštabona\ud
and the fourth on the outskirts of Koštabona. We discovered that the costs incurred in the\ud
construction of the buildings were almost the same in all four locations, whereas the sales\ud
prices for buildings located in Koper and on the outskirts of the city were much higher than the\ud
other aforementioned location
Development of lightweight self - compacting concrete with declared properties
Get PDFThe aim of the master thesis was to develop lightweight self-compacting concrete made of lightweight\ud
aggregate and with declared properties, such as compressive strength class and maximal target density.\ud
Self-compacting properties were determined by measuring rheological properties and selecting the\ud
optimum range of yield stresses and plastic viscosities as a result of these measurements. In the first part\ud
of the thesis properties and specifications of lightweight aggregate and lightweight concrete are given.\ud
The data were obtained using relevant literature and standards. Common explanations about rheology\ud
of concrete and models for the description of liquids are also given, along with presentation of ultrasound\ud
testing and thermal current measurements. The second part of the thesis, which is experimental,\ud
represents the main part of my work. First the used test methods are given and the testing protocols are\ud
described, with obtained results of the tests. After that the test results are analysed. Concrete mixtures\ud
were divided in two groups. Preliminary concrete mixtures were first tested in order to define the\ud
composition of the main group of the mixtures. For the main mixtures rheological properties were first\ud
measured for different influencing parameters and presented in the form of rheographs. Then selected\ud
mixture was used to cast a concrete wall of 100 cm x 230 cm x 6 cm. The homogeneity of concrete in\ud
the wall was evaluated using ultrasound testing. The thermal insulation properties of the concrete were\ud
evaluated using thermal flow measurements. The study was carried out in the framework of cooperation\ud
with an enterprise that uses such concretes in practice
Influence of simultaneous energy and structural retrofitting actions for the case study of older building at Tomšičeva street in Kranj
Get PDFThe purpose of the thesis was to determine the necessary measures for energy rehabilitation of the\ud
building located at Tomšičeva ulica 7 in Kranj in order to reach current requirements of standards for\ud
thermal efficiency of buildings. At the same time during energy rehabilitation of the building we also\ud
wanted to apply strengthening measures with minimal interventions to increase its seismic resistance.\ud
For the analysis of seismic resistance of peripheral walls (facades) we used the FaMIVE method which\ud
allowed us to calculate the possibility of formation of the in plane collapses and out of plane collapses\ud
of the facades. The data used for the analysis was collected from in-site inspection of the building and\ud
from available documentation of the building. By mounting anchors the value of ESC factor which allow\ud
us to determine seismic resistance of facades was successfully increased for more than a double. In the\ud
second part of the thesis analysis of building’s energy efficiency was made. The data about current status\ud
of the building envelope was obtained by using thermography. We performed an energy efficiency\ud
analysis of the building with the software Gradbena fizika URSA 4.0. Results show that installation of\ud
thermal insulation onto façade, onto ceilings and replacement of old windows significantly reduces heat\ud
losses. Efficiency of heating system can be further increased by installing wood biomass boiler. The\ud
comparison of costs showed that 88 % of the whole investment represent the costs of energy\ud
rehabilitation, particularly because of the costs of the new windows, installation of thermal insulation\ud
on the facades and installation of new boiler. By implementation of measures on the building envelope\ud
we have successfully met conditions about maximum thermal transmittance trough external elements of\ud
the building, which are described in regulation PURES 2010
Identification of the potencial couses of excessive humidity and proposal of measures for primary school building
Get PDFWe often forget the indoor environment that has a major impact on our well-being and health. In addition to negative effects on people we also have negative effects on building health and the building envelope. In this thesis I have focused on the parameter of relative humidity and air temperature, which strongly affect the user and the building. By identifying the possible causes of excessive humidity, I have proposed remediation measures at the site of the Heroja Janeza Hribarja Primary School in Stari trg pri Ložu. For data analysis, we record critical points of building envelope (indoor and outdoor) with thermal camera and digital camera. We also made measurements of relative air humidity and air temperature in the art classroom and distributed questionnaire among the employees at the school. With the TEDI software I have checked the appropriateness of the structural complexes with legislation (PURES 2010). After analysing and comparing results, I have come to the conclusion that the majority of employees feel discomfort in the area where they are located. The building insulation is poor and inadequate, which is also evident in the thermograms with visible thermal bridges. Thermal flux of the structural complexes does not meet the requirements given by Pravilnik o učinkoviti rabi energije v stavbah (PURES 2010). The upper limit of relative air humidity (60%) in the art classroom is often exceeded. Rooms in the buildinga are also poorly ventilated. A thermal insulation is recommended and so is the use of thermostatic valves and other remediation measures presented in this thesis
Reconciliation of the land cadastre and state border data at the Slovenian-Italian border
Get PDFThe main topic of the thesis is registering of state border and adjustment of land cadastre data with the state border data for the case of Slovenian-Italian border. For this purpose, data from the official state border evidence and land cadastre data in the Republic of Slovenia have been used; additionally, archive data about evidencing of state border at the regional office of the Surveying and Mapping Authority in Nova Gorica have been used, and legislation as well as other professional literature from the study field have been studied. In the thesis, some basic terms from the study field are explained in the beginning, followed by the description of Slovenian-Italian border, including its changes through the history and its current situation. Further on, the contents of state border documentation and procedures for recording of the state border are presented, accompanied by the examples from the practice at the Slovenian-Italian border. These study cases are mostly about the adjustment of the cadastre data with the data about state borderline from the official evidence, and about the procedures for preparing new documentation about the state border. In the framework of this thesis, we tried to define the reasons for such a discrepancy between the land cadastre data and data about state border, which lead us to the conclusion, that this was mainly the consequence of digitalisation of the state border documentation and of the cadastral maps. Copying, tracing and transfer of the data among different media, formats and forms of evidence also played an important role
Effectiveness analysis of measures to avoid typical thermal bridges
Get PDFThis thesis deals with a comparative efficiency analysis of measures that are most frequently used in building practice to eliminate typical thermal bridges. The analysis complies with the requirements specified in the Rules on Efficient Use of Energy in Buildings (PURES, 2010) with reference to Technical Guideline TSG-1-004:2010, Efficient Use of Energy. Efficiency calculations for individual measures used to eliminate a thermal bridge were conducted with the THERM 7.3 (LBNL, 2014) computer application. The efficiency analysis was carried out on the basis of four most common types of thermal bridges experienced in residential homes. I started by analysing the base case of a thermal bridge without any remedial measure used, and continued with at least two most frequently used solutions for each of the four cases of thermal bridges. Through calculations made for these measures, I obtained the needed base information for further analysis. The analysis showed that the position of thermal insulation is of crucial importance and represents the main reason for variances in results. I have found that the position of window installation is crucial for eliminating the thermal bridge at the window-wall junction. The only really efficient measure for elimination of a thermal bridge at the building junction of a balcony with external and the inter-floor slab is the »interruption« of the reinforced concrete plate with a structural thermal break element. Thermal bridge at the\ud
junction of an inter-floor slab and external wall can be eliminated by considering the limitation of U-factor (thermal transmittance factor) prescribed in TSG-1-04:2010, that is by sufficient thickness of the heat insulation envelope of a building. Correct positioning of heat insulation is also of key importance for elimination of a thermal bridge on the junction between outer wall and sloped roof
