Geodetic measurement of the control network on point of the zero order in Kog
Full text linkEvery geodetic network point of the zero order in Slovenia contains control network for monitoring the local stability of the reference zero order point. At one of the points of the zero order, which is located in Kog a precise geodetic survey was performed. Observations were treated and adjusted in height and horizontal control network in order to obtain local positional coordinates of the reference points and the control network points that will be used to identify the movement of these points in subsequent epochs on the network. In the end an analysis of the accuracy of the results obtained was made. The thesis describes the\ud
procedure of precise geodetic measurements in the field, used instruments, processing of the measured values and the adjustments of data
Environmental impact of brine discharge from desalination plant
Full text linkPopulation growth demands constant increase in drinkable water production. Many developing countries have a shortage of fresh water so they have to tap into alternative water sources. Desalination technologies provide the possibility to produce fresh water from sea or brackish water. Every\ud
technological process has its by-products; the major one in desalination is the rejected brine. This thesis presents some research made on the influence of brine discharge on the marine environments and the brine chemical characteristics from the desalination plants in the Mediterranean region. The second half of the thesis is dedicated to brine discharge modelling and calculation of near zone dilution. Analysing data received from the oceanographic buoy Vida, the near zone dilution for a small desalination plant in the gulf of Trieste is being calculated. Calculations are made for three different output flows with different output diffusers with the average and critical temperatures and salt concentration of the sea environment
Management of public infrastructure in the local community
Full text linkThis master's thesis examines a pressing problem of Slovenian local communities relating to the management of public infrastructure. The water supply infrastructure that was built in the previous century is aging and deteriorating: breakdowns are increasingly frequent, the level of water loss grows greater each year, and moreover the owner (the local community) often does not have access to data on the physical state and risks of the water supply infrastructure, which hinders the selection of sections in need of repair. A major obstacle to carrying out reconstruction investments is the problem of ensuring the financial resources required. Accounting records of fixed assets, which form the basis for the calculation of depreciation, which in turn is used to set the rent for the use of infrastructure, are incomplete. Moreover, fixed assets are valued based on the old purchase price, which does not reflect their actual current value. As a result, the funds collected for reconstruction investments are insufficient. The local community is obligated to be a good manager of property (infrastructure), but what this means in practice is left up to each one’s own conception. For this reason in this master’s thesis we analyzed established standardized practices in other countries for managing material resources and then tested them in the specific case of the water supply infrastructure in the Municipality of Borovnica. This thesis investigates the life cycle of public infrastructure as envisaged by the International Infrastructure Management Manual while also taking into consideration Slovenian legal provisions. Assessment of cost efficiency in the sense of economic indicators in the case of public infrastructure is not possible. Successful management requires ensuring efficiency through the entire lifespan of the infrastructure, which can be achieved through proper planning, consistent implementation, monitoring of effects, and continuous updating of the management plan for public infrastructure
Desalination as a new water source
Full text linkDesalination has become one of the main methods for producing drinking water, especially in the countries without safe drinking water sources (for example the Midwest countries). However, there is an increasing demand for such a water source also in other countries due to increasing demand for drinking water, lower cost of desalination and advances in technology. This thesis describes different technologies, their strengths and weaknesses, environmental impact and presents a study of a desalination device set-up to supply a nearby city. The study contains a selection of the size of the device depending on the needs of the city and estimates the cost of such a device (investment, operation, maintenance). In conclusion, calculation results are given with comment on calculation results obtained
A use case of federated model for the development of 5D BIM
Full text linkBuilding information modeling (BIM) offers a contemporary support to design, construction and management of buildings. In this thesis, my intention was to present advantages of BIM, with an emphasis on the federated models and OpenBIM approach. In order to demonstrate BIM, I chose the business-shopping center in Grosuplje and developed a 5D model of it. This concrete case was useful as a basis for demonstrating all benefits and effects of BIM methodology. Four software tools were used: ArchiCAD 19 to design architectural model, Tekla Structures 20.0 to develop construction model, MS Project 2016 to plan a schedule to build and Navisworks manage 2016 to develop 4D and 5D model
Static analysis of timber roof structure of aluo cultural heritage building at Erjavčeva st. in Ljubljana
Full text linkThe thesis presents static analysis of timber roof structure of Academy of Fine Arts and Design cultural\ud
heritage building at Erjavčeva St. in Ljubljana. In the first part of the thesis, the measurement process and overview of existing documentation is described. Due to inaccessibility and prohibition of structure modifying, at many parts of the structure the basis for drawing an architectural plan of existing situation were old plans and old instructions for building timber roofs. Afterwards, 3D architectural model of roof structure was made. It was the basis for computational model, which was determined by taking Eurocode standards and manual for the design of building structures to Eurocode standards into account. Such as an architectural model, the computational models for every structure element, which carried out controls in limit states are also shown. Static analysis was carried out in SAP2000 software. Based on calculated internal forces, displacements and basic terms for limit states controls, given by standard SIST EN 1995- 1-1:2005, structure element controls were carried out for ultimate limit states and serviceability limit states. In the last part of the thesis results are summarized. In ultimate limit states most of the structure elements are safe, while in ultimate serviceability limit states most of the structure elements are useless
Development of water and waterside space for leisure activities
Full text linkThe doctoral thesis evaluates the potential and development planning of leisure activities on rivers (kayaking, canoeing, rafting, hydrospeeding, etc.). Considering the starting point that the planning of spatial development in the natural environment for the purpose of leisure, sports, recreation and tourism represents a challenge to preserve the values of the environment, ensuring sustainable development, preservation of health and well-being of people, hypothesis is proposed that the segmentation of the core areas for the development of leisure activities of water and riparian area may establish a system of measures for their balanced development. The resarch of Slovenian river space was assessed by a survey questionnaire of motives, significant and disturbing factors for users who spend their free time in paddling activities. The survey results were used for the specification of the basic characteristics of the streams, considered when assessing the appropriateness of river sections for paddling activities on eight Slovenian rivers according to the adjusted method RIVASSlo. A detailed research of the current situation and potential for the development and verification of the hypothesis, was accomplished in a test region of the Soča River in the Upper Soča Vally. The research has shown that it is reasonable to determine river segments, considering the type of activity, and to divide the segments into sections according to morphological features (degree of difficulty) and the location of the entry/exit points, and that the estimate of the suitability of river sections for the paddling activity on individual sections presents a basis for drafting measures to improve individual attributes. We developed a theoretical model concept of the core area management for the establishment and development of waterways for paddling activity, which pursues an aim the conection of spatial, environmental, socio-economic, cultural and other aspects of sustainable development in the river space. In the thesis we have not been dealt with other forms of leisure activities such as fishing or digging with kayaking can also be in conflict and activities on the waters such as navigation, exploitation of water forces, the water supply, water treatment, purification, irrigation, etc., which may affect on the execution of leisure activities
Building shape influence on insolation potential of facade envelope
Full text linkIn my graduation thesis I analysed the influence of building's floor plan shape on its insolation, or more precisely, on insolation of its vertical external envelope. Buildings were located on the area of the city of Ljubljana. The models of buildings were modelled using Google SketchUp 2016. Nine different models were defined, which were divided into two groups – buildings with simple (square, rectangular and circular) floor plan shapes and buildings with complex floor plans (shapes of O, H, U, T, Y and L). Analysis was carried out with the use of a Sunhours application. Insolation of the models was researched with changing theirs geometrical characteristics (height and floor plan dimensions). Insolation of analysed buildings was evaluated using two methods: comparison of the building's allyear cumulative insolation of its external envelope and comparison of the building's envelope area \ud
normed potential of the insolation of its external envelope. I concluded that for evaluation of the buildings in terms of insolation, method with envelope area normed potential of the insolation is more suitable. External envelope's total surface area has a fundamental influence on the results in this method. Through the acquired results, the Y shape building was shown as the best in terms of insolation
Energy renovation of Vila Bled
Full text linkThe thesis discusses Vila Bled which currently operates as a four-star hotel. The facility only operates during warmer months due to its high heating costs as a result of its energetic inefficiency. In addition, the building is protected due to having cultural heritage and therefore, some limitations about renovation measures must be considered. Relevant legislation in the energy sector is presented, the restrictions that apply due to its cultural heritage protection, and the proposals based on pre-made\ud
studies of the building. The current state is also analysed, its energy balance, calculation of insolation\ud
and adequacy of building's envelope. It was assessed that the current situation exceeds the criteria given in Rules on efficient use of energy in buildings five times over. Based on the limitations of cultural heritage, protection proposals are given that would be feasible. The present proposals are: replacing windows, additional roof insulation, and replacement of energy source for heating with a wood chip furnace or heat pump water. These suggestions are taken into account in the assessment of the energy balance of the building and compared with each other. At the end of the thesis, it is suggested which of the pending proposals would be most effective, namely the simultaneous replacement of windows by selecting the appropriate glazing, additional roof insulation, and replacing energy source for heating with biomass. It is estimated that the annual energy required for heating is\ud
still not sufficient by the criteria given in Rules on efficient use of energy in buildings, but it would improve the current situation by 22 %
The role and significance of cultural landscape in spatial planning - the case study of the Bizeljsko region
Full text linkThis thesis deals with the cultural landscape in the area of the local community of Bizeljsko. A diverse, slightly undulated terrain with a significant cultural variety is typical for this area. The prevailing landscape patterns are the flat country adjecent to the river Sotla and stream Dramlji with meadows and fields and the area with hills where vineyards, orchards, fields, meadows and forests on its sunny sides are present. In the mentioned area has some of the best vineyard positions in the entire municipality of Brežice. Bizeljsko is part of the Bizeljsko – Sremiš\ud
vineyard area. In the first part of this thesis the local community of Bizeljsko will be examined through natural and societal geographic characteristics. How the cultural landscape is and has been presented in promotional materials will also be determined. We examined the current state of viticulture and fruit growing and did an interview with a municipality employee from the field of farming advisory. In the second part of this thesis the cadastral municipality Orešje was the focal point. We suggested guidelines for future development in the sense that the existing, traditional cultural landscape would be preserved. The preservation of the cultural landscape \ud
is important from the viewpoint of economy, ecology, culture and tourism. For the preservation of a recognisable cultural lanscape suitable farming activities that shape and maintain notable landscape patterns must be encouraged
