Understanding sustainable strategies in low-cost housing

Abstract

Purpose This paper aims to understand the incorporation of sustainability methods of construction through the study of a low-cost housing Tamil Nadu Housing Board settlement in a locality in Chennai, India. Such a study helps to arrive at proper design decisions and incorporate a participatory approach involving the residents to enable the developers, here the decision-makers of the government, cater to the local interests. Design/methodology/approach First, a survey was conducted to understand the local conditions and people’s aspirations. Along with this, the parameters pertaining to a green housing were derived and compared with the needs of the locals, to arrive at the most influencing parameters by decision-making trial and evaluation laboratory model (DEMATEL) analysis. Findings The study finds that parameters viz. “ensuring basic services” and “social inclusivity” happen to be the causal factors that seem to influence the needs of the locals. These factors therefore can guide the future plans to redevelop the settlement or construct similar settlements in a more sustainable way. Originality/value This paper is a unique study to combine the twin pillars of low-cost housing and sustainability, which helps in developing settlements that are conducive to the city’s socio-developmental requirements as well as respectful of the natural environment. Further, the analysis conducted through DEMATEL method could essentially guide the decision-maker to tackle urban challenges in the most locally suitable and sustainable approach.
