Radiant cooling and heating systems provide an opportunity to achieve significant energy and peak demand savings compared to conventional systems. As the use of these systems grows, particularly in zero-net-energy (ZNE) and other advanced low-energy buildings, the correct design and operation becomes a critical aspect of meeting expected performance.
Speakers at this full-day symposium include building industry professionals including engineers, architects, builders, commissioning specialist and owners who are creating high-performing non-residential buildings in California and elsewhere. Presenters include UC Berkeley researchers who recently completed a multi-year study that led to new insights, reports, case studies and design tools.
This event is free and open to the public, available for on-site session and by live webinar.
Speakers and Presentations

Anthony is currently the Healthy and Resilient Buildings Program Manager at San Francisco International Airport where he manages the Net Zero Energy (sustainability) and the Activation Planning Services (commissioning, activation and simulation) programs for the Airport’s Capital Improvement Program.
Jingjuan Dove Feng, PhD, PE
Technical Project Manager, Research and Technology Commercialization Advanced Energy, TRC Energy Services
Jingjuan Dove Feng is a Technical Project Manager at TRC within the Research and Technology Commercialization group. Ms. Feng has a PhD from UC Berkeley and has over 10 years of experience in building science and mechanical systems design and control. Her work includes research and design of high-performance buildings, code and standard development and project management. She has actively participated in several research projects on the topic of radiant systems and has published several journal articles on radiant systems, including cooling load and cooling capacity analysis methods, modeling approach and model predictive control of high thermal mass systems.
Lyn L. Gomes, PE, CCP, LEED AP, CLCATT
Senior MEP coordinator at DPR Construction
Lyn L. Gomes brings her experience as an HVAC engineer together with her commissioning and construction knowledge to help make building systems not only work, but work better together. Lyn is chair of the Building Commissioning Association’s national conference and a board member of the Building Commissioning Association. In her spare time she serves on the industry advisory board of Techbridge, an after school STEM program for girls. Lyn received her Bachelors of Science from Cal Poly San Luis Obispo.
Paul Raftery, PhD
Professional Researcher at the Center for the Built Environment, UC Berkeley
Paul Raftery’s focus is on improving building energy efficiency by investigating advanced integrated HVAC systems. He holds a PhD in Engineering for developing a new method for calibrating building energy models to detailed measured data. He has over a decade of hands-on experience in HVAC engineering, controls, fault detection, simulation, and new technology development. He is a Fulbright Fellow, an active ASHRAE member, and a co-Principal Investigator on two California EPIC research projects: a recently completed $3M four-year project on radiant systems, and an ongoing $2M three-year project on smart ceiling fans.
Peter Rumsey , P.E., LEED AP BD+C, CEM, FASHRAE
Founder and CEO, Point Energy Innovations
Peter is the founder and CEO of Point Energy Innovations, a new consulting firm focused on working directly with owners and developers in the U.S. and globally on the next generation of profitable, low-energy, high-performance and decarbonized buildings and industrial facilities. He has received numerous awards including the Renewable Energy Innovator of the Year and ASHRAE’s prestigious Award of Engineering Excellence, only awarded five times in ASHRAE’s 100-year history.

Participants will see examples of buildings with high-performance radiant heating/cooling systems in non-residential buildings and be able to name at least two key factors that shape engineering and design of these systems.
Participants will learn how advanced energy simulations enable design and guide operations of high-mass radiant systems to reduce and shift peak heating/cooling loads and reduce energy costs.
Participants will gain an overview of recently completed research from the Center for the Built Environment at UC Berkeley on optimizing radiant systems including case studies, design and operation tools and methods, and other key research findings, and learn where detailed information on the research is available.
Participants will gain an overview of architectural integration of radiant systems and be able to name at least three common owners’ criteria for acoustics, architectural finishes and structural integration.
Participants will learn common contractor concerns, how to avoid gaps in scopes of work for radiant systems, and can summarize project management approaches to maintain quality in design-building project delivery.
