Wildfires in the western United States have been increasing in frequency and magnitude in recent decades, resulting in poor air quality that constitutes a major environmental risk factor for human health and mortality. Researchers at CBE have created a novel software tool for smart thermostats to improve the air quality inside homes at times when outside air becomes unhealthy during wildfires.
CBE is one of 30 research testbeds supporting the California Test Bed Initiative, a lab-based commercialization development program for innovators and entrepreneurs working to bring early to mid-stage clean energy concepts to market. CalTestBed will award vouchers worth up to $300,000 to test and validate candidate technologies at one of nearly 30 testbeds across the UC system and Lawrence Berkeley National Laboratory.
The results of a new study challenge an industry standard which cited an optimal indoor temperature to improve work performance. The study followed the methods of previous research, but used additional data and rigorous statistical methods. The results found no evidence for a relationship between work performance and temperatures commonly found in offices, and none that should be adopted as an industry recommendation.
Discovery Elementary School in Arlington, Virginia, has earned the 2021 Livable Building Award from UC Berkeley’s Center for the Built Environment. A program jury from CBE’s building industry consortium lauded how the “purposeful design of the building supports students and teachers by creating a diverse learning environment with seemingly endless ways to engage students.” The project is also one of the first certified zero-energy building schools nationwide.
Hurricanes, wildfires, and floods produce dramatic images of destruction, but heatwaves cause more deaths in the U.S. each year. Research and new tools help us understand how fans can provide resiliency during extreme heat events. Fans may use 10 to 100 times less energy than air conditioning, reducing the impact on power grids during these events.
Imagine an ice cream parlor that offers only one flavor of ice cream, one chosen by scientists based on what an ‘average’ person wants. While this idea seems absurd, a similar logic has been used in establishing standards for thermal comfort in buildings. A group of CBE staff, industry partners and others have developed a revision to thermal comfort standards that acknowledges the variability in human comfort preferences.
CBE researchers are part of a research program on “Resilient Cooling for Buildings,” supported by an international association of governments, industry and researchers. The main objective is to support the rapid adoption of resilient, low-energy and low-carbon cooling systems for buildings. This work will also serve to help cities and communities better contend with climate-based and demand-based power outages.
Using an extensive trove of thermal comfort research data, CBE’s research team recently published a set of ‘nudges’ to the existing adaptive comfort standards to improve comfort in commercial buildings while potentially reducing energy use. This work updates the landmark study from 1998 by Gail Brager and Richard de Dear on the Adaptive Comfort Model (ACM), which demonstrated that people in naturally ventilated buildings were more comfortable with seasonal temperature variation compared to people in air-conditioned buildings.
Millions of people are working at home to prevent the spread of Covid-19, creating stress and impacting our well-being and productivity. Science shows that time spent in nature may improve our health and emotions, however, when we are not able to be in nature physically, we may derive benefits simply by access to windows with views. A study recently published by CBE found that a view from a window has positive impacts on emotion, cognitive performance and thermal comfort.
CBE recently launched an online tool for designing with ceiling fans, making it easier for designers to create highly energy efficient and comfortable spaces. The tool was created based on years of research that have demonstrated that ceiling fans can keep a person cool while using only a fraction of the energy required by air conditioning.
