Key Findings
- 01Standard comfort index (ISO 7730) predicted a comfort temperature of 23.14°C.
- 02Occupants in an open-designed tropical building rated air temperatures up to 32°C as slightly cool, due to a mean air speed of 2.34 m/s and 66.25% relative humidity.
Application
Design takeaway
Prioritize passive cooling strategies like natural ventilation and airflow to achieve thermal comfort in tropical environments, rather than solely relying on mechanical cooling based on rigid standards.
How to apply
When designing buildings in tropical climates, conduct site-specific assessments of air movement potential and consider occupant acclimatization to higher temperatures.
Project actions
- 01When researching comfort, consider both objective measurements and subjective user feedback.
- 02Explore how environmental factors like airflow can be manipulated to improve comfort without increasing energy use.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Combines objective environmental data with subjective user feedback.
- +Focuses on a relevant and often overlooked aspect of thermal comfort in specific climates.
Limitations
The specific building design and location might not be representative of all tropical settings.
Reliability & validity
The use of standardized measurement equipment and a survey method contributes to reliability. Validity is supported by comparing objective data with subjective user experience, though generalizability might be limited by the specific case study.
Think critically
How might cultural factors or individual acclimatization further influence thermal comfort perceptions in tropical regions?
Design Principles
"Thermal comfort is adaptive and influenced by environmental factors beyond temperature, such as air movement and occupant behavior."
This challenges traditional design assumptions based on fixed thermal comfort standards. Designers can create more comfortable and energy-efficient spaces in the tropics by prioritizing natural ventilation and airflow, rather than solely relying on mechanical cooling.
What This Means for Your Design
In hot places, if there's a good breeze, people can feel cool even when the air is quite warm, much warmer than usual comfort guides say.
How to use in your project
- 1.Use this research to justify a design that incorporates natural ventilation or enhanced airflow for thermal comfort in a warm climate.

Paragraph starter
Research indicates that in tropical climates, occupants can adapt to higher air temperatures (up to 32°C) if sufficient air movement is present, challenging the applicability of standard thermal comfort indices like ISO 7730. This suggests that design solutions should prioritize natural ventilation and airflow to achieve thermal comfort and energy efficiency.
