Despite the high potential of passive strategies combined with solar systems for saving energy in buildings, the energy consumption of their temperature control requirements is one of the biggest problems facing today’s energy sector as it has severe repercussions on the environment. As a result, past decades have seen a growing interest in promoting energy efficiency in construction, which in turn has stimulated research into this area.
One such example includes international initiatives on a range of projects that form part of the ECBCS and SHC programmes from the International Energy Agency (IEA). Within the framework of current regulations, this interest has also been demonstrated through various European Directives and in the gradual entry into force of legislation on this subject (Technical Building Code. Updated Basic DB HE Document on Energy Saving 2013). The implementation of the new European Directive, EPBD 2010, requires technologies to be available that can achieve nearly zero energy buildings as well as methods to reliably assess and profile the energy performance of constructive components and buildings.
The majority of current regulations that refer to energy quality and to energy saving in the temperature control of buildings apply to the design phase, calculating the theoretical energy consumption, usually by using dynamic thermal simulation software. However, some studies have revealed that the real performance following construction of the building can be significantly different to this theoretical performance. It is clear that testing and in-depth modelling of real-scale buildings has to be carried out, reinforced by integrating an extensive range of low consumption energy technologies. Read more…
