Prioritizing occupant thermal comfort through passive design strategies in low-income tropical buildings can significantly reduce reliance on energy-intensive cooling systems, leading to substantial energy savings.
Sustainable Energy Research · 2025
Key Findings
- 01Passive design strategies like natural ventilation and thermal mass are crucial for thermal comfort.
- 02Appropriate material selection can significantly influence indoor temperature regulation.
- 03Integrating occupant comfort with energy efficiency requires a holistic design approach.
- 04Socioeconomic factors and stakeholder engagement are critical for the adoption of energy-efficient solutions.
Application
Design takeaway
In tropical regions, design for thermal comfort first, as this will naturally lead to energy efficiency and cost savings, particularly for vulnerable populations.
How to apply
When designing for tropical climates, especially in cost-sensitive projects, begin by exploring natural ventilation, shading, and high thermal mass materials before considering active cooling systems.
Project actions
- 01When researching thermal comfort, look for studies that link it directly to energy use.
- 02Consider the specific climate zone and the typical building materials available in that region.
- 03Investigate how user behaviour can influence thermal comfort and energy consumption.

The reliability of this review depends on the quality and consistency of the studies it synthesizes. Validity is enhanced by its broad scope and focus on established principles of thermal comfort and energy efficiency.
Think critically
To what extent can passive design strategies fully replace active cooling systems in all low-income tropical building scenarios, and what are the trade-offs?
Design Principles
"Design for thermal comfort to achieve energy efficiency and occupant well-being."
Understanding and designing for thermal comfort directly impacts energy consumption in buildings, a major contributor to global energy use and CO2 emissions. For low-income populations in tropical climates, this translates to reduced utility costs and improved living conditions, while also contributing to broader environmental sustainability goals.
What This Means for Your Design
Making buildings comfortable without using much electricity is possible in hot places by using smart design, like good airflow and materials that keep cool.
