With the emerging trend towards fully electrified buildings, plus the demands from a growing IT sector, utilities and building portfolio managers are facing growing peak demands while also seeking solutions towards decarbonization and grid resilience. This session features three emerging HVAC strategies, with detailed case studies that can move these ideas from research to implementation.
Carlos Duarte will present a recently published simulation study exploring how radiant cooling systems can reduce strain on the grid during peak demand hours, evaluating numerous parameters such as the scheduling of system operation to optimize for climates. With simulations of 16 climate zones in California, plus 14 additional climates, these results can inform optimization for load shifting in radiant systems.
Jiwon Park will discuss a case study of an all-electric medical office building that implemented heat recovery chillers to reduce emissions, providing a higher coefficient of performance than air-to-water heat pumps, with a smaller equipment footprint. Results show the technical feasibility of these systems, but also their complexity and variability, with a proposed new metric for assessing performance in such systems.
Finally, Tharanga Jayarathne will describe the field implementation and validation of a novel control strategy that optimizes supply air temperature resent. Recent implementations in three commercial buildings demonstrate its potential as a cost-effective and scalable control strategy, with energy or cost savings up to 20%. This event is free and open to the public, and co-sponsored by PG&E and UC Berkeley’s Center for the Built Environment.

Wildfire Resilience: Hardening Structures & Communities (Webinar)
2026-07-14 08:30 - 12:00
Course Description:
There is an urgent need to perform parcel assessments in order to harden homes, parcels and communities to “stand alone” to survive wildfires. Why? Multiple fires and other conditions may outpace the efforts of first responders. What is needed to mitigate risks for individual buildings and communities? A comprehensive structure and parcel assessment based on a burn test study Kliewer and Associates (K&A), performed and the Hazard Mitigation Methodology (HMM) published by the National Institute of Standards and Technology (NIST).
In early 2024 and funded by SCE, Kliewer & Associates performed a burn test study that represented a high-density setting. One conventionally framed structure was not hardened against wildfire and had no defensible space. The hardened structure had a structure separation distance of 10’ from the burn structure and had defensible space. Thermocouples and cameras were placed inside and around the hardened structure to measure the temperature behind the fire rated door, window, and in the middle of the ceiling. The resulting forensic study performed after the burn test was completed, exposed vulnerable locations in the building assembly. Discover what features were most effective for survivability, and what features increased vulnerability and damage. Find out why some homes survive an event while the surrounding structures are destroyed.
This study sheds light on how to rebuild or retrofit structures and parcels with ignition-resistant building assemblies and how full structure hardening against direct flame exposure may greatly increase the probability of high-density homes surviving wildfires.
Building Scientist Ron Kliewer, Research Engineer Chad Gretzner, and Chris Mellen, P.E., will discuss the nuts and bolts of a wildfire hardened building envelope and the energy efficiency gains that are achievable.
Agenda:

Taught simultaneously as a webinar and in-person at SCE’s Energy Education Center (EEC), Irwindale classroom and partly in the EEC Smart Energy Experience Home using the full size Wildfire Hardened High-Performance Wall (HPW)/High-Performance Attic (HPA) displays.

Next Generation Passive Solar & Passive House
2026-07-22 09:30 - 11:00
Event Description
We all learned the principles of passive solar design in school – south facing orientation, strategic windows, thermal mass, etc., but the old rules don’t apply in the same way. In the meantime, Passive House building principles are folding into every-day construction. Modern buildings should still incorporate a range of passive strategies, but they need a new spin on the implementation to account for improved insulation, prevalence of high-performance glazing, and efficient HVAC systems and lighting.
