The lab studies the thermal and air environments of buildings through field measurements and numerical analysis.
AboutAbout the lab
Predicting invisible physical phenomena and applying them to design.
The Lee Lab is a research group exploring building science, including thermal, air, light, acoustic, and water environments, building services, field measurements, and numerical analysis.
The lab aims to develop design technologies that accurately predict and evaluate the invisible physical phenomena occurring inside and outside buildings, so as to ensure occupants' safety and comfortable living.
It tackles a wide range of issues, including evaluating ventilation efficiency, predicting the behavior of indoor pollutants, analyzing thermal comfort, energy-saving buildings, disaster prevention, and infection control.
The lab is always looking for people with diverse backgrounds, such as architectural engineering, environmental engineering, mechanical engineering, electrical engineering, and computer science.
Key terms
- CFD
- Computational fluid dynamics. A method that uses calculation to visualize in detail the distribution of airflow, temperature, and humidity in a room.
- ZEB
- Short for Net Zero Energy Building. An energy-saving building pursued through integrated design of the architecture and its building systems.
- PMV/PPD
- Indices used to evaluate comfort. PMV is the Predicted Mean Vote, and PPD is the Predicted Percentage of Dissatisfied.
- Age of Air
- An indicator used, together with ventilation efficiency, to evaluate ventilation performance numerically.

ResearchResearch themes
The lab conducts research that accurately predicts and evaluates invisible physical phenomena such as heat and airflow inside and outside buildings, and links the results to optimal design. It covers the built environment broadly, including energy-saving buildings, indoor thermal environments, wind environments, and air quality.
*Illustrative imagePromoting Energy-Saving Buildings and ZEB
The lab aims to establish building methods that combine passive design and active technologies to reduce energy consumption while maintaining comfort. It examines integrated design of buildings and building systems toward achieving ZEB, as well as energy simulation.
*Illustrative imagePredicting Indoor Thermal Environments with CFD
Using computational fluid dynamics (CFD), the lab predicts and visualizes the distribution of airflow, temperature, and humidity indoors, aiming at space design that protects occupants' comfort and health. Comfort is evaluated with the indices PMV and PPD.
*Illustrative imageWind Around Tall Buildings and Building Surroundings
The lab analyzes the wind around high-rise buildings and the wind pressure on exterior materials, aiming to ensure pedestrian safety and the structural safety of buildings. It investigates how a building's shape affects the surrounding airflow, and examines countermeasures against wind damage and ways to improve natural ventilation performance.
*Illustrative imageIndoor Air Quality and Infection Control
The lab aims to clarify how chemical substances and fine particles spread, and to build methods for maintaining clean air environments that prevent health damage. It examines the removal of substances that cause sick building syndrome and of particulate matter, and the prevention of aerosol dispersion for infection control, and evaluates ventilation performance using the age of air.
