Abstract

Purpose - The aim of this paper is to study and evaluate the situation of different affordable housing projects with an eye toward developing a new affordable and sustainable housing model in the hot-arid climate of Jordan. There is a clear interest in providing affordable housing, yet sustainable and environmental issues are highly marginalized. To bridge this gap, and to meet Jordanian housing needs while tackling environmental problems, this research has analyzed the environmental issues of selected housing projects in Jordan, aiming to determine the existing problems. In addition, it proposes a solution through a sustainable and affordable housing model that was analyzed and compared to the previously studied housing projects. Design/methodology/approach - A cross-sectional design strategy was adopted and a mixed design method was used. Information related to the physical and operation characteristics of buildings was collected through the review of “as built” drawings and other relevant documents. Further information was obtained from field surveys and personal interviews with architects and decision-makers in the housing sector. Energy consumption patterns of these housing projects were analyzed using the DesignBuilder simulation program. Water efficiency was assessed using the BRE Code Water Calculator. Based on the previous analysis, a new housing model was developed that was evaluated in terms of energy and water consumption. Findings - The analysis shows a significant difference among different housing projects in terms of energy cooling and heating loads in different climatic regions in Jordan. Energy analysis proved that the proposed model is energy efficient in different locations and it can save up to 50.4 per cent of annual energy usage in comparison with existing projects. In addition, it can save around 43 per cent of water consumption by using a number of modifications for saving water. Originality/value - Most of the housing initiatives focus on providing affordable housing, yet sustainable and environmental issues are highly marginalized. This research will bridge the gap by reducing the operation cost of affordable housing through adapting and implementing sustainable measures of design and construction.
