ArchiLambda Lab is housed within the Department of Architectural Engineering at The Pennsylvania State University and maintains close affiliations with the Materials Research Institute and the Department of Architecture. Our laboratory seeks to deepen the understanding of thermal and optical processes, dynamics, and interactions across scales ranging from the nano/micro material level to components, buildings, communities, and urban environments, elucidating their broader implications for resource efficiency, occupant comfort and health, climate resilience, and sustainability.
​
Our research focuses on three interconnected domains: climate-responsive building systems, human-environment interactions, and building-urban/climate dynamics. To address these areas, we employ a robust methodology that integrates experimental investigations, computational modeling, and subjective assessments. Through this multifaceted approach, we inform innovative engineering and design strategies, support the development of more resilient built infrastructures, and ultimately foster healthier, more sustainable environments for all.

Window coatings for energy savings
We have been recently interviewed by the Penn State News team for discussing the recent work published in Energy Conversion and Management. This work examined the energy-saving properties of a coating comprising nanoscale components that can reduce heat loss and better absorb heat. They also completed the first comprehensive energy savings analysis of the material at the building scale (02/2022).

NSF CBET Fund
Compounding the effects of the building (envelopes and systems) and built environment characteristics, the social and behavioral characteristics of households and urban-rural inequality can result in differing levels of vulnerability to extreme temperature events. This NSF-funded research aims to build an urban-rural regional assessment, preparedness, and response system for extreme temperature events for use during the transition to global sustainability.

Podcast - lighting for energy savings
On the latest episode of the Growing Impact podcast, Julian Wang and Anne-Marie Chang have discussed their seed grant project that investigates how indoor lighting can be adjusted to affect user thermal responses to save energy on a building’s heating and cooling and positively impact human health (09/2021).
NSF CMMI Fund
We receive a new research grant from the NSF CMMI program for investigating new building envelope technologies with dual-modality characteristics: generating thermal radiation in winter via the photothermal effect and reducing summer solar heat gains in summer via the photovoltaic effect. See the details in this link. (07/13/2020)
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)
