Science Extract: A recent study confirms the effectiveness of Response Surface Methodology (RSM) with desirability functions for optimizing building designs in tropical climates, balancing the often conflicting goals of minimizing indoor overheating hours (IOH) and maximizing useful daylight illuminance (UDI). Published in Scientific Reports, this research offers a computationally efficient multi-objective approach to sustainable design in resource-constrained settings.
Implications for the Global South: The findings hold significant promise for improving housing design in tropical regions of the Global South, where overheating is a prevalent issue and access to mechanical cooling is often limited. Utilizing passive design strategies optimized for both thermal comfort and daylighting can enhance indoor environmental quality, reduce energy consumption, and improve the well-being of inhabitants in resource-constrained settings.
Actionable Insights: Architects and building designers in tropical regions can adopt RSM with desirability functions as a practical and efficient method for optimizing passive design strategies in new construction and retrofitting existing buildings. Policymakers can promote the use of RSM and similar optimization techniques in building codes and regulations to encourage sustainable building practices. Funding programs could provide incentives for research and implementation of optimized passive designs to improve housing affordability and sustainability in the Global South.
ESG Integration: This research promotes a holistic approach to sustainable housing that aligns with ESG principles by optimizing building designs for both thermal comfort and daylighting. The methodology reduces reliance on energy-intensive cooling systems and promotes energy efficiency. It also enhances indoor environmental quality and improves the well-being of inhabitants. Finally, the efficient use of resources and the promotion of sustainable building practices support responsible governance and long-term sustainability.
Key Takeaways for the Global South:
- RSM with desirability functions offers a computationally efficient method for optimizing building designs in tropical climates.
- Passive design strategies optimized for both thermal comfort and daylighting enhance indoor environmental quality and reduce energy consumption.
- The methodology promotes a holistic approach to sustainable housing that aligns with ESG principles.
Global cooperation is essential to facilitate the dissemination and adoption of RSM-based optimization techniques in building design in the Global South. Promoting sustainable housing practices is critical for achieving equitable and resilient development, improving the well-being of communities, and safeguarding the environment for future generations.
