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 buildingпїЅs 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 wi...

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, buildingпїЅs orientation, windows placement, and buildingпїЅs 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 obse...
