It adopts a multidimensional outlook that encompasses institutional, social and technical aspects surrounding the dwellings. The institutional aspect is addressed through an investigation of financial, legislative, technical and cultural barriers to the implementation and uptake of...

The thesis explores energy retrofitting options for enhancing the energy efficiency of residential buildings in Jeddah, Saudi Arabia.

Presenting case studies from the Netherlands, Sweden and Austria, the approach adopted in this disse...
