Buildings are complex systems that have to fulfil many functions. They have to provide a healthy and comfortable indoor environment, must be energy efficient and ultimately must be sustainable (Boemi, Irulegi and Santamouris, 2016). However, over the years, the need to improve the energy efficiency of the building sector was given first priority. The main reason for this is the following. It is well known that the contribution of the building sector to the total energy consumption is significant. More specifically, buildings account for 40% of the final energy consumption within the European Union (EU Parliament, 2012). In the UK, the domestic sector contributed to the final energy consumption in 2014 b y 27% while the industrial sector contribution was equal to 17% (Department of Energy & Climate Change, 2015). This has major environmental as well as economic consequences. IPCC argues that gas emissions due to human activities have increased substantially since the pre-industrial era. This is probably the main contributor to the monitored warming since the mid-20th century (Pachauri et al., 2014). In addition, from the EU’s perspective, improving energy efficiency will have a positive impact on the index of employment and economic growth (EU Parliament, 2012).
In this context, action has been taken at both levels; European as well as national. Specifically, EU is obliged to reduce greenhouse gas emissions and energy consumption by 20% while at the same time has to improve…
