A better energy efficiency of a building can be obtained by implementing passive and active energy efficient design strategies. The initial design phase starts with implementation of several passive strategies, i.e. strong thermally insulated building envelope, building?s orientation, windows placement, and building?s aspect ratio, window to wall ratio, use of thermal mass, natural lighting, shadings and other solutions. However, looking at how building are designed, built and operated nowadays, it can be observed...

This article deals with the modification of the nozzle and its entire assembly with a hot end, so that it was not necessary to use a tephlon insertion and it was possible to reach the maximum temperatures of the nozzle reaching 280°C and above. With the gradual development of 3D printing technology FDM (fused deposition modeling), i.e. the fritting of the thermoplastic in the shape of the fibres and putting it into the layers, more demands are placed on the materials used. Materials with a greater temperature of g...

Buildings account for significant energy consumptions in the global consumptions, according to the International Energy Agency. The path towards 2050 is that of nearly Zero Energy Buildings (nZEB), a path that should change the way that buildings are designed in current practice. The design of a building?s envelope is always focusing more on the heat transfer of top components (i.e. exterior walls, terraces, roofs) and less on the heat transfer in bottom components (i.e. floors on the ground, walls in contact with...
