Abstract:

In the development phase of the energy audit documentation, a significant volume of calculations is generated when evaluating the thermal performance of the building envelope elements.The number of distinct elements of a standard building, e.g. types of exterior walls whose thermal performance is influenced by the position of the wall on the building height,by the geometric dimensions of the elements, by the existence of various types of door and windows openings, leads to an increased variety of thermal performances that should be assessed.For the energy auditing and expertise activity, several computer programs are available, programs that can determine the energy consumptions of buildings requiring as entry data the thermal performance of the building envelope elements.These thermal performances are given with varying degrees of accuracy, usually in the current field of the element without considering the linear thermal bridges.When the linear heat transfer coefficients ψ are used, the details existing in the thermal bridges atlases do not cover the real situations encountered in the current design, thus resorting to approximate details.There exist situations when the technical documentation of the building is not available, which leads to various assumptions regarding the detailing of the building envelope.In this regard, the project proposes the development of a methodology accompanied by software called THERMOG that evaluates the thermal performance of the building envelope under actual operating conditions using the aerial and terrestrial thermography method.The thermal performance assessment is carried out based on the geometrical and physical properties of the component materials upon making the expertise and not based on the normed values or the values declared by the manufacturer.The methodology developed in the project significantly reduces the duration of the auditing activity of a building and obtains results based on the actual behaviour of the build

Abstract:

In the construction domain, the energy represents the key-point in achieving efficient buildings.

The project proposes the improvement or institutional performances between three universities and two research institutes for the revival of the research activities and transfer of knowledge between partners.

The 4 proposed projects, centred on the efficient energy buildings, are focused on two principal research directions: (i) use of smart facades with low-thermal transfer, actively integrated for the enhancement of internal comfort and possessing a passive control of energy (by using the solar energy) and (ii) smart energy efficiency through building automatization and solar energy collectors. The resulted system, the smart house, is conceived thus to minimize the input energy for maintenance.

The Project 1 has as main objective the determination of mechanical properties of cellular materials used as thermal insulations in smart façade systems, through mechanical compression, bending and toughness fracture testing of such cellular materials.

Project 2 is focused on obtaining, characterizing and testing of high-property materials used for smart facades as thermal insulation materials and as support for special property layers: photo-catalytic layers and with reduced absorption/reflexion of UV-VIS-IR radiation.

The Project 3 has as main objective the theoretical and experimental investigation of the implementation of the electric power distribution in direct current for individual households or in small communities (smart-grid), with renewable energy sources integration.

The scope of the Project 4 is to implement the knowledge and data resulted from projects no. 1-3 through a modular laboratory demonstrative application. The project will perform an integrated study on the influence of the facades and the energetic contribution to the internal comfort of the building by considering different façade systems and respectively by integrating a smart-grid energy system.

Abstract:

TRANStoWORK – Work based Learning in Architecture, Engineering and Construction (AEC) Industry: the transition of young people to Work is a project funded by the 2017 Call of the Erasmus+ Programm of the European Union, inscribed within Key Action 2- Cooperation for Innovation and the Exchange of Good Practices - KA202 - Strategic Partnerships for vocational education and training

The main objective of TRANStoWork is enhance, reinforce and structure work-based learning (WBL) in vocational training courses for young people aged 18 to 35 (EQF level 4-5-6), particularly in those areas of production that show a gab in skills and a lack of propensity to change.

In order to do so, collaboration between those operating in the production process (the companies), the Vocational Training operators and the social partners – Entrepreneurship Associations and Labor Unions – is needed to make it possible for work-based learning to become pervasive within the training path, using shared methods.

The production sector taken into consideration is the Construction sector in its most innovative sense: the Architecture, Engineering and Construction (AEC) Industry.

Abstract:

In order to know the answer of buildings at exterior climatic parameters, with the aim of assuring the thermal comfort in buildings at minimum costs, is needed to know the plan or spatial thermal field for each element of the building envelope. The window surfaces represent areas with the highest thermal permeabilities,through which a important amount of energy is transmited from interior to exterior, energy loss that will increase the heating/cooling and ventilation needs. The hygrothermal measures which give the thermo-energetic behaviour of the glazing areas, is crucial to be known from the initial design stage, considering that the intervetion in the operating phase will come with technical difficulties and great costs. The project aim was the development of an automaton calculus programme,expert type,called VITRAJ,plan and spatial(bi and tri dimensional). The program uses the programming environment windows-delphi- and c++,which can establish in a plan or spatial network the values of the thermal field with a high number of nodes for the discretisation mesh. The obtained results are listed as numeric values or graphs, as a field form or izothermal curves. Taking into account the plan or spatial temperature field the following hygrothermal design parameters are obtained: temperature, thermal resistances, average, minimum or maximum heat flows which enable the thermo-energetic optimization of the constructive solutions utilised for glazing areas and shading devices used for new and existing buildings. The program is validated based on European and Romanian design norms, that validate modeling and simulation software for thermo-energetic design of building components.

Abstract:

The research undertaken to achieve the Ph.D. Thesis is part of the overall effort of specialists and of the European Community for energy consumption reduction in buildings operation, for reduction of the greenhousegas emissions with a direct benefit on obtaining a sustainable built environment. A set of modules software were developed during the PhD program, with the aim of simulating the thermal and energy performance of windows, doors and shading devices. These module programs allow numerical simulation and modeling of the heat transfer phenomenon on plane or spatial planes for complex constructive componentsbuilding envelope with complex with variable thermal conductivities, considered in real operating conditions.The computer programs for the analysis of thermal and energy performance of the opaque and glazing area of the building envelope elements and of the building as a whole presented in the thesis have been used to design new buildings, to establish the energy performance of building envelope components in the design stage and in the rehabilitation process of existing ones.
