Heidari Faculty of Architecture, University of Tehran, Tehran, Iran Journal Article 2013 11 27 Energy consumption in the residential sector is a complex socio-technical problem that can be explained using a<br />combination of physical, demographic and behavioural characteristics of a house and its occupants. In this paper, by<br />using the energy consumption data for the residential sector of Shiraz in Iran, the effect of built area (BA) and<br />occupant number (Occ) on annual energy consumption (Ec) was investigated. Ten houses from the first modern<br />period of the city were selected randomly from 1971 up to 1991. It was found that the built area and Occ did not have<br />a direct impact on energy consumption in Shiraz’s residential buildings; however, the household behaviours and<br />houses’ building construction directly affected energy saving. Houses with maximum BA or maximum annual energy<br />consumption were not the same; the same held for Occ. The average annual energy consumption per capita of 1 m2<br />built area of the case studies was 0.087, and for each occupant it was 2.487.<br />  https://jdesert.ut.ac.ir/article_52333_c70f8367bc5d8b45cae48ee89169e04a.pdf
