Adapting the Affordable Housing Prototype in Indonesia

Abstract

Approximately twelve million Indonesian households reported needing a habitable home, a condition that is aggravated by population growth and urbanization. Besides the housing shortage, Indonesia's building and construction sector is inevitably facing climate change, which poses a higher risk of adverse effects to vulnerable communities. With the massive demand and due to a limited budget, a public housing program for low-income people built by the Indonesian government only met the minimum requirements of livable housing but disregarded the need for increased sustainability. Leveraging climate-responsive design to improve housing design and strengthen the community while tackling climate change is crucial. This research identifies efficient and effective design strategies to achieve indoor thermal comfort, zero net energy building, and a resilient community of public housing in Indonesia. The research methodology involves analyzing case studies to develop passive design patterns that promote energy effectiveness and social well-being. The strategies are classified as building orientation, building form, façade, circulation, and landscape that could optimize thermal comfort and improve the community. However, enhancing affordable public housing performance could be challenging in Indonesia's hot and humid climate if only relying on passive design. The study runs an energy simulation that analyzes how mechanical strategies can support energy efficiency and production. The existing public housing is adapted according to climate-responsive and community-focused design frameworks.
