(Optimisation and validation of a specialised software used for calculating the thermal performance of the building envelope components, developed based on aerial and terrestrial thermography method)

 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 building.
