Abstract
A social housing sector is one of the main areas globally with regard to energy efficiency and consumption. The sector was growing rapidly during post-war decades to serve population growth. The sector today becomes outdated and inefficient to the climatic responses. Building operational performance requires to evolve over time due to climate change. It appears that more energy needs to be consumed than normal, which increases the consequential causes of GHGs(Greenhouse gases) emission in the long term. As in the post-war of economic and population growth, the environmental concerns were not prioritized to initially put into the account of building design. These post-war social housings are moving to their last stage of their lifespan and require to be retrofitted, renovated, or demolished in near time. This thesis integrates the use of computational design tools and retrofitting strategy by examining performance of building envelope and space arrangement of a typical social housing in a tropical c
