The recast of the Energy Performance of Buildings Directive 844 from 2018 stipulates the need of meeting the criteria of nearly Zero Energy Buildings, at both new and existing buildings. Although that the target is starting to get embraced by the design community, the process of modelling such buildings is very time consuming. The modelling and simulation of the construction joints, known as thermal bridges implies knowledge regarding numerical simulation and also the acquisition of commercial licenses in order to...

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...
