To rehabilitate the habitability. Scenario simulation for consolidated urban areas in Warm regions

Abstract

Present research seeks to analyse the extent to which CO2 emissions can be diminished by means of different measures of energy efficiency simulated in a consolidated urban area on the Mediterranean coast. The study focuses its scope in analysing the incidence of summer climatic conditions over a Nineteenth Century urban fabric. Assessment is through the establishment of three scales of intervention: the neighbourhood, the plot and the building. These scales are assessed by three different scenarios, the original and two retrofit proposals. The study demonstrates that a potential reduction of CO2 emissions takes place if a retrofit programme is jointly undertaken at the three different scales. It also reveals how specific actions can reduce indirect emissions depending on the location, orientation and wind regimes, and how diverse typologies of buildings behave differently according to their location in the neighbourhood, in the plot and according their envelope. © 2017, World Scientific and Engineering Academy and Society.
