ASSESSMENT of ENVIRONMENTAL SUSTAINABILITY of BUILDING CONSTRUCTION: A CASE of WOLISO TOWN

Abstract

The rapid expansion of building construction in Ethiopia has raised concerns about environmental sustainability, necessitating the green building practices. This study assesses the environmental sustainability of building construction projects in Woliso town, examining the existing conditions of buildings, stakeholder awareness, and challenges in implementing sustainable construction methods. A descriptive mixed-method approach was employed, utilizing site observations, questionnaires based on the Leadership in Energy and Environmental Design (LEED) checklist, and interviews with key stakeholders, including tenants, building owners, environmental protection officers, and construction professionals. Data was analyzed through Statistical Package for the Social Sciences (SPSS) and thematic analysis of transcription, coding and verification steps. The findings reveal significant deficiencies in green building standards, with many buildings lacking essential features such as urban heat mitigation, energy efficiency, and water conservation measures. Key issues identified include the Urban Heat Island effect, excessive energy and water consumption, and poor indoor environmental quality. Barriers to sustainability adoption include weak regulatory frameworks, limited expertise, and misconceptions about the costs associated with sustainable construction. While stakeholders demonstrated moderate awareness of environmental sustainability principles, this knowledge has not effectively translated into practice. The study underscores the urgent need for policy intervention, capacity-building programs, and regulatory enforcement to enhance sustainable construction practices. By integrating environmental sustainability principles into local building practices, Woliso town can foster a more resource-efficient and environmentally responsible built environment.
