ArchiLambda Lab is based in the Pennsylvania State University's Department of Architectural Engineering and has its roots in both illumination and mechanical system options. This laboratory’s goal is to understand the thermal and optical dynamics and implications of interactions among buildings, occupants, and external climatic stimuli. The current research efforts encompass three main aspects: bridging the gaps between radiometric and photometric studies in the building environment, integrating spectrally-selective smart material and structures into building envelopes and fenestration systems, and discovering human responses to the interaction between thermal and visual elements. Our research methodology combines experimental, computational, and subjective methods.

ASES Solar 20/20
Four presentations, with the topics of solar data modeling, analytical window models, solar gains through glazing on thermal comfort, and solar building education were made by the lab members in the virtual conference of the ASES 20/20. (06/23/2020)
IEE SEED Grant
The lab's proposal of “Building Energy Savings by Tuning Indoor Lighting” is selected for funding by the Institutes of Energy and the Environment (IEE) Seed Grant Program of Penn State University. The project is to discover the potential thermal-visual interactions in the controllable indoor environment. We will be collaboratively working with Dr. Anne-Marie Chang in Biobehavioral Health and Nursing and Dr. Javad Khazaei in Electrical Engineering on this interdisciplinary project. (04/01/2020)
