Designing for radiant systems and thermally active surfaces represents a key opportunity for integrated design and high-performance buildings. While radiant systems can be inherently more energy efficient than air-based systems, their success requires close collaboration between architects and engineers to ensure that the building design reduces loads to levels achievable by radiant systems. This collaboration between the disciplines has a direct relationship to the ultimate performance of the system and comfort of the building. Key decisions must be made early in the design process to ensure the feasibility and performance of an installed system. A wide spectrum of configurations and types of radiant systems are available for designers, with each having different capabilities, capacities, and complexities according to their setup. This presentation will cover some general rules of thumb to consider for radiant systems, as well as provide an overview of the key architectural and engineering design decisions associated with each system configuration.


Dr. Woods is a licensed mechanical engineer who started working at the IDL as a graduate student back in 2013. His dissertation used energy models paired with weather forecasts to predict how a radiant slab should be managed to maximize occupant comfort. His current research focus is on the integration of surface temperatures into building energy management systems. Dr. Woods has taught courses in advanced thermodynamics and energy modeling. In the office, he spends his time working on energy models and estimating savings from energy upgrades; out of the office he is usually fly fishing or gardening. Dr. Woods earned his B.S. from Montana State University, his M.S. from Boise State University and his Ph.D. from the University of Idaho.
