The Directive 2010/31 UE (EBPD) introduced the “Nearly Zero Energy Buildings” linked to cost optimality, where energy benefits are related to economic benefits. The “Cost Optimality” methodology is applicable both to new and existing buildings, as introduced in the Regulation …
The hygrothermal conditions in historic solid masonry are expected to change for the worse, with the application of internal insulation. Nevertheless, internal insulation plays a role in a holistic energy retrofit of historic buildings. With careful considerations and correct application, …
In the UK, 20% of houses were built before 1919 and are protected from energy efficiency requirements that would unacceptably alter their character. To meet carbon emission reduction targets, however, it is necessary to keep the number of buildings exempt …
Passively designed buildings are the tradition of historic areas of metropolitan Cairo. According to UNESCO, Cairo was inscribed on the World Heritage in 1979 under the title of “Islamic Cairo”, recognizing its unquestionable historical, archaeological and urbanistic importance. Among Islamic …
To improve the energy performance of restored cultural heritage buildings, it is necessary to know the real values of thermal conductivity of its envelope, mainly of the facades, and to study an intervention strategy that does not interfere with the …
Historic Scotland commissioned this technical paper to assess the effectiveness of two inexpensive and minimally invasive methods for improving the thermal performance of single glazed windows. This report describes the work conducted by the Scottish Energy Centre (SEC) at Edinburgh …
A recent concern on the time scale of architectural and urban heritage of historic city centres, energy efficiency of existing buildings takes on a major and universal dimension in response to climate change. thermal renovation works will have consequences and …
