"The next generation of buildings should support human health and productivity as well as the highest level of environmental sustainability"

Human-Building Integration Lab (HBI Lab) is in the Building Science Program in the School of Architecture at the University of Southern California located in Los Angeles, U.S. We are conducting quality research focusing on comprehensive study of advanced building technologies and design to promote building performance in energy efficiency, net zero energy, indoor environmental quality (such as thermal, air, acoustic and lighting conditions), occupant health and productivity. Our lab consists of Professor Choi, and multiple MS and PhD students in Building Science, as well as post-doctoral researcher and visiting scholars. Our lab's research focuses and activities can be found in greater detail under the "Research" tab.

Dr. Joon-Ho Choi is an Associate Professor of Building Science and Associate Dean of Research and Creative Work in the USC School of Architecture. Prior to taking the position, he worked as an assistant professor in the Department of Civil, Architectural, and Environmental Engineering at Missouri University of Science and Technology. He earned his Ph.D. degree in Building Performance and Diagnostics at Carnegie Mellon University. He also received his Master’s degree in Architecture at Texas A&M University in the U.S., and a M.S. degree in Architectural Engineering at Yonsei University in Korea.

 

Dr. Choi's primary research interests are in the areas of advanced controls for human-building integration, sustainable building design/performance, comprehensive post-occupancy evaluation, and indoor environmental quality.

The HBI Lab participated in the USA National Science and Engineering Expo in D.C. 

EPA's National Sustainable Design Expo as a part of the USA National Sci. and Eng. Expo was held at the Washington Convention Center on Apr. 7 and 8, 2018.  The HBI Lab participated and presented the EPA-NSF sponsored Human-Building Integration project. It was greatly successful with the "world-class" lab members. About 300 visitors with many children came by and gave us a lot of positive comments and questions. Go HBI! Go Trojan!!

Dr. Choi is invited to the National Chin-Yi University of Technology in Taiwan by Professor Fu-Jen Wang, a former president of the ASHRAE Taiwan Chapter. Dr. Choi will visit the University located in Taijun in mid-October 2018, to give a seminar to Professor Wang's research group. Dr. Choi will talk about one of his research themes, the Human-Centered Environmental Control and Cyber-Physical System. After the visit, he will attend the 2017 Healthy Building Conference to be held in Tainan, a southern part of Taipei. 

Invited Seminar at the Technical University of Denmark, Copenhagen, 2017

Completed the first phase of Dr. Choi's immersive virtual environment study: Investigation of the Physiological Differences between Immersive Virtual Environment and Indoor Environment in a Building

The HBI Group has started a collaborative project with the Virtual Reality Research Group in the USC's Institute for Creative Technologies. Dr. Shin, who is an Associate Researcher and Environmental Psychologist, and Dr. Choi will start a research project, entitled "Impacts of Virtual Reality on Human Factors in a Built Environment," which is sponsored by the V.R. Research Foundation and one Korean Industry Partner. 

Invited Seminar at the Korea Institue of Civil Engineering and Building Technology (KICT)

In November 2017, Dr. Choi gave a talk to the researchers at KICT about "User-Centered Building Environment in the Context of Smart Cities."

Dr. Choi's group win Young researcher Best Paper Award at the 10th International Conference on Indoor Air Quality, Ventilation and Energy Conservation in Buildings in Bari, Italy.

Dr. Choi was invited to the 2019 International Conference on Human Dimension of Building Energy Performance, held in Venice, Italy, as a Keynote Speaker.

VOICE OF AMERICA interviewed Dr. Choi and reported the impact of his research for workers' personal comfort and wellbeing.

Dr. Choi was invited to give a research talk to the high school students of the STEM Academy in Hollywood.
