Achieving urban sustainability is a complex process that includes improving buildings’ resilience and energy efficiency by using the optimum thermal insulation solution. With the advent of new energy ...restrictions, it is very important to find the best compromise between the price of the thermal insulation material and energy savings because, sometimes, the initial cost of a thermal rehabilitation seems to be very high. The purpose of this study is to illustrate the variations in the amount of heat energy required by a multi-storey residential structure in Romania that uses 14 various kinds of thermal insulation materials. The energy demand is determined using the dynamic method using a building energy simulator that can evaluate the energy usage of lighting, warmth, ventilation, climate control, and water heating.
A typical characteristic that generally defines historic buildings is certainly the age of the buildings. The life cycle of historic buildings is out of date, the vast majority being hundreds of ...years old. Naturally, as time has gone by, buildings have been subjected to the degradation process. The cultural and historical value of these buildings are the subject of a particular focus on finding rehabilitation and restoration solutions that meet both architectural and structural requirements. A lot of the historical buildings are buildings with structure from brick masonry walls, as is and the case of the Romanian National Opera from Timisoara. Thus, this paper aims to address the subject of the deficiencies faced by the materials that make up the facade of the historic masonry building - Romanian National Opera Timisoara in order to find the optimal solution for rehabilitation and restoration. In the first phase, the characteristics of the analysed building are presented as well as the historical context throughout its existence. The methodology of travertine testing is described, including pull-off and porosity tests and morphological and mineralogical analyses as well as a thermography of the façade. The results of the non-destructive and destructive tests carried out on the bricks extracted from the masonry wall of the Opera House as well as the testing procedure are also presented. A comparison of the methods of rehabilitation and restoration of brick masonry buildings was also made. The paper includes details regarding the initial situation of the building’s damaged façade, but the main scope is to evaluate the causes of the façade’s cracks which have led to the need of façade rehabilitation and restauration works. The deficiencies of the travertine plates that make up the façade as well as the structural walls are described. Thus, for the rehabilitation of the masonry walls, a reinforced plaster lining was chosen, at the same time the existing cracks were filled by injections of cement milk, while for the restoration of the façade, the existing travertine tiles were replaced with new tiles with the same aesthetic configuration. In conclusion, the focus is on highlighting the efficiency of the chosen rehabilitation solution as well as that of restoration works executed in order to prolong the building’s life cycle. The conclusions of the study also highlights the importance and necessity of preserving heritage buildings in Romania in order to complete the historical and cultural space.
The space regarded as land, as the primary support of mankind has undergone continuous evaluations from the source of raw materials, means of agricultural production, forestry source to the location ...of social and urban activities being thus an invaluable asset. The land’s potential is invaluable, so that its efficient, correct, accurate management is a sine qua non condition for keeping it with all its benefits. Modern, its management can best be done through the Geographical Information System. The territorial arrangement combines the balanced development of the exhaustible geophysical elements, respecting the cultural, social, traditional (historical) elements of the environment and helps to harmonize them and to avoid the negative evolutions. Territorial planning is the basis of sustainable development policies. The theoretical notions that support the realization of the case study - creating the solar map of Timiș county, Romania using open source GIS programs - are thoroughly documented, including aspects regarding solar energy mapping and the methodology of solar irradiation calculation as well as the current global context in which emphasis is put on the use of renewable energy
In line with the objectives established by the “European capital of culture” initiative, the entire community is involved in embarking socio-economic and infrastructure projects supported by an ...information platform which ensures efficient data management for the municipality. This platform should provide a good visibility of the candidate city in the context of enhancing the contribution of culture to its long-term development in accordance with its priorities and strategies. In particular, an important role is played by the implementation of a spatial data geoportal at Local Administration level (Timişoara City Hall) to streamline the data workflow and provide easy access to it in order to increase the visibility of cultural and historical heritage of the municipality. The need of this geoportal arises from the fact that Timişoara has the widest architectural heritage area in the country, of important value to both Romania and Europe. The preservation of this cultural heritage is a duty for the authorities and also for the owners. The present paper brings forward proposals and trends in implementation of a dedicated geoportal for the management of heritage objects to complete the existing urban GIS primarily aiming to contribute to fostering the urban planning and the sustainability of the “European capital of culture” project. This geoportal should include the 3D models of the cultural heritage objects for better preservation over time or restauration purposes and offer virtual tourism tours if they are made available by means of webGIS. That is why, the authors propose a webGIS solution in order to make the geoportal available on the City Hall's webpage. The actuality of the paper is given by the fact that preserving cultural heritage and historical sites represents an important issue that must be taken into account when urban planning projects are required for developing the model of urban growth.
The continuous development and the rapid economic growth of Timisoara municipality (western Romania) have contributed to the increase in transport needs. The number of motor vehicles registered by ...natural persons (125195), and the number of motor vehicles registered by legal entities (35303), results in one motor vehicle per two persons. To these figures are added the commuters, students and tourists who come by car to the city. Thus, the main cause of road traffic is the increasing number of vehicles, day by day. In order to maximize road capacity and speed up the pedestrians’ flow, traffic lights are used at approximately every intersection. As such, the proper use of traffic signals can lead to more efficient traffic management. Due to the evolution in time, technology comes to aid precisely to solve such problems and especially to streamline road traffic issues. Thus, the article presents the workflow that includes identifying the elements of a traffic light intersection, measuring, and processing them, in order to realize a layout plan that can be introduced into a GIS system to manage traffic lights in an intelligent manner. Using GIS (Geographical Information System) technology, the problem of road traffic can be solved appropriately and efficiently. Based on the main characteristics of urban traffic and the efficient, appropriate use of traffic lights, approaching, and treating the information according to the area, its spatial and geographical location through coordinates, GIS technology can be used to solve problems given by the zonal agglomeration of heavy traffic centres, or areas with peak hours. The fluidization of the traffic can ensure better circulation and aeration of the crowded areas and the avoidance of the congestion of some central arteries, especially during rush hours.
This paper aims at presenting geodetic studies that are in close connection with landslide modelling and must be used for continuously monitoring the areas affected by geomorphological hazards. ...Although sometimes the geodesist's contribution to certain projects for landslide monitoring meant to develop early-warning-systems or risk maps is not adequately appreciated as stated in FIG Working Group (2006) 20 and he is only seen as supplier of measured geometric data, the geodesist has a significant contribution through his abilities regarding the modelling of dynamic systems, like strategic constructions (dams, tall buildings etc.) or landslides and data interpretation The study of how an objective affected by landslides behaves in time implies geodetic measurements performed at pre-set time intervals using state of the art technologies, which allow processing and review of data thus obtained in a three-dimensional system. Moreover, the goal is to set the stage for the shaping and optimization of monitoring networks by choosing the optimal research methods to be used.
This work is part of the INTEREG IPA CBC Romania Serbia project entitled RORS394 Know to Develop - Through knowledge to business and smart development of Banat. The project's objective was to ...increase employment opportunities and employability of young people through the creation of organizational and institutional conditions for cross-border and networked improvement of education, knowledge and skills that will meet the needs of the economy and labour market. One of the modules of the project refers to 3D scanning as a high-resolution and accurate recording of the objects in 3D space is of high importance for many subjects of different domains of interest such as monitoring landslides, archaeology, cultural heritage etc. Traditional techniques for 3D data acquisition either restrict the size of the scanned objects or impose demands on the stability and structure of the surface. On the other hand, various society fields demand realistic 3D city models. For urban planning or historical buildings even ancient fortresses, analysing in a 3D virtual reality world is much more efficient than imaging the 2D information on maps. For public security, accurate 3D building models are indispensable to make strategies during emergency situations. Navigation systems and virtual tourism also benefit from realistic city models. Manual creation of city models is undoubtedly a rather slow and expensive procedure, because of the enormous number of buildings and complexity of building shapes. The rapid development of cities also adds to the cost of manual city model updating. Nowadays, a lot of research has been done to automate the procedure of city reconstruction, and a number of approaches have been proposed. These approaches differ with respect to input data, automation level, and object representation. In this context terrestrial 3D imaging laser scanning forms a method to acquire a large number of precise data points in 3D space representing the surface of the objects under investigation. These scanners are an effective tool for the collection of data to create a digital elevation model of the topography of a site as well as of the surface of a single archaeological deposit. The acquired data can be used for documentation purposes only, but the further processing provides the possibility for virtual reality modelling for public presentation, restoration planning or virtual reconstruction. Laser scanning technology and the final deliverable, materialized as the three dimensional model of the terrain, emphasises the importance and the applicability of geodesy in giving proactive solutions to architectural and engineering problems.
Cilj rada je upoznavanje s geodetskim istraživanjima koja su usko povezana s modeliranjem odrona zemlje i moraju se primijeniti za trajno nadziranje područja u kojima dolazi do geomorfoloških ...opasnosti. Iako se ponekad nedovoljno cijeni doprinos geodeta nekim projektima za nadziranje odrona u svrhu razvoja sustava za rano upozorenje ili izradu karata s prikazom mogućih opasnosti, kako je navedeno u FIG radnoj grupi (2006) 20, i promatra ih se jedino kao dobavljače izmjerenih geometrijskih podataka, njihov je doprinos važan u modeliranju dinamičkih sustava, kao što su strateške konstrukcije (brane, visoke zgrade itd.) ili odroni zemlje te u interpretaciji podataka. Istraživanje ponašanja tijekom vremena nekog objekta zahvaćenog odronom uključuje geodetska mjerenja obavljena u ranije utvrđenim vremenskim intervalima primjenom najsuvremenijih tehnologija, koje omogućuju obradu i pregled tako dobivenih podataka u trodimenzionalnom sustavu. Uz to, cilj je postaviti okvir za oblikovanje i optimizaciju mreža za nadziranje biranjem optimalnih istraživačkih metoda.
