International Building Performance Simulation Association

New York Chapter (IBPSA-NYC) Quarterly Meeting

With electric light accounting for about a third of the energy used in buildings, there is the promise of substantial energy savings through effective daylight design. However, the generic implementation of solar radiation and daylight control calculations in commonly used energy analysis software may be too crude to accurately capture the performance of the daylight design. Additionally, energy analysis tools do not address visual comfort and glare concerns which are critical to the success of a daylight design. Using currently available analysis tools, there is the potential to merge daylight and energy analysis in order to assess the effectiveness of daylight design strategies.

Speaker: John An is an associate with Atelier Ten and serves as the principal daylighting, shading design and lighting energy analyst for the New York practice. His research work has focused on the evaluation of lighting energy standards, and visual comfort and glare prediction in electric and daylighted spaces. John provides environmental design and LEED consulting for a wide range of residential and commercial projects.

John has held teaching appointments at Harvard and the Boston Architectural Center in courses on daylighting, new and smart materials, and environmental systems. He also speaks on environmental design at universities, conferences and public forums. John is a LEED Accredited Design Professional, and holds a B.Arch from Cornell University, a Masters in Design and Environment and a Doctor of Design, both from Harvard University's Graduate School of Design.
