“…The BIM methodology encompasses the control, direction, monitoring, and control of the project and the management of all the information that is generated throughout the development of the project: from the initial planning stages, through conceptual design and selection of alternatives, procurement from suppliers, the establishment of the most advanced phases that include structural design and facilities [12]. Without forgetting, of course, the monitoring or control and the management of the construction and future maintenance of the facilities, 4D, 5D, 6D, and 7D Stages [7], are key aspects such as energy efficiency [13], functional safety and sustainability of buildings and infrastructure, the last two being crucial (See Table 1) [14]. The revised bibliography attributes the sixth BIM 6D dimension to the model information in relation to the energy efficiency and sustainability of the building model.…”

One of the least used aspects of BIM (Building Information Modeling) is the ability to obtain the energy model of the building using the BIM methodology known as BIM 6D. This digital information model allows simulating the real energy behavior of the building and the improvement in the building’s lighting systems, both natural and artificial, in particular daylighting. In this way, the BIM 6D simulation allows us to make design and operation decisions for the building, not only for new buildings that must be, in accordance with current legislation, NZEB (Nearly Zero-Energy Building) but also for the rehabilitation of existing buildings. Particularly in buildings for sanitary use, BIM 6D allows an exhaustive analysis of the energy impact of said rehabilitation, guiding it towards an improvement in energy and light efficiency, which in turn provides greater quality and comfort in the use of the sustainable building. This subject of study is especially important in public buildings for hospital use. Buildings where energy efficiency and comfort, oriented towards optimal and efficient lighting, are two fundamental criteria highly appreciated by patients and citizens in general. Once the energy model of the building has been obtained, it is possible to study and identify possible alternatives to improve energy efficiency and improve lighting, as well as to analyze the possibilities of incorporating other more efficient forms of renewable energy, such as the use of daylight. In this work we can see how applying a set of simulated improvement actions in BIM 6D achieves an energy saving of 50% in general and up to 13% only by acting on lighting systems, allowing the decarbonization of buildings with high energy consumption, such as hospitals, and in turn, will lead to an improvement in the energy certification of these buildings; thus achieving a better and higher quality of habitability, using more efficient forms of lighting and transforming buildings into more sustainable spaces.

“…Another ecological aspect is the estimation of the greenhouse gas emissions during the production of roofing materials these aspects are presented in [15] for bitumen modified atactic polypropylene (APP). Another rarely discussed way to reduce energy consumption is presented in [16], where a significant impact of the roofing material on the total energy consumption is noticed. An attempt to find the most practical solutions in economic and energetic terms is presented in [17].…”

In this work, four representatives of roofing felts are under consideration. Special attention is paid to the mechanical behaviour under the tensile load of the samples. The results of strength tests for the entire range of material work, from the first load to sample breaking, are shown with respect to a specific direction of sample cutting. Moreover, a unique study of the microstructure obtained with the scanning electron microscope and chemical composition determined by energy dispersive spectroscopy of the tested materials is presented. The significant mechanical material anisotropy is reported and moreover argued by microstructure characteristics. In perspective, the outcomes can give comprehensive knowledge on optimal usage of roofing felt and proper mathematical modelling.
