Lessons Learned from 20 Years of the CBE Occupant Survey

Occupant surveys provide valuable insights into how well a building is performing. Historically these surveys focus on comfort and satisfaction. However, as our attention shifts to occupant health and wellbeing, we wonder whether our tools are measuring all we need them to. In a recent paper, we look at the CBE Occupant Survey tool and its database to evaluate its measurement and benchmarking properties, while also identifying new enhancements intended to support the creation of spaces that truly benefit those who use them.

Comfort Hacks for Outdoor Winter Dining

The Covid-19 pandemic has challenged the restaurant industry, forcing many beloved institutions to close, while many have pivoting to take-out service and outdoor dining only. While we rally to support our favorite eateries, colder climates present some serious challenges to patio dining. In this Centerline post we borrow ideas from CBE’s experience with prototyping and testing innovative and energy-efficient ways to help people comfortably dine al fresco as we get through a dark and cold pandemic winter.

Unprecedented: Reflecting on the Events of 2020

As we reach the final weeks of 2020 — a year we are all happy to put behind us — we take a moment to reflect on the many challenges of the year, and also some successes made possible through the support and resilience of our industry partners and collaborators who navigated with us through truly unprecedented times.

Modernization of a Mid-Century High School Earns 2020’s Livable Building Award

The historic renovation and expansion of Lick-Wilmerding High School in San Francisco has been recognized as the winner of CBE’s 2020 Livable Buildings Award. The design team conducted comprehensive carbon accounting, and the project is expected to yield net positive energy performance. Conferred annually by UC Berkeley’s Center for the Built Environment, this program recognizes buildings that demonstrate ‘livability’ in terms of occupant satisfaction, sustainability and architectural design.

Hiding in Plain Sight: In Pursuit of High-Performance Facades

No aspect of a building is more visible, or holds more didactic potential, than its facade. However, what you see is not always what you get. In spite of the facade’s explicit visibility, a facade’s appearance may not reveal much about a building’s performance in terms of energy, resilience or how it impacts the health and welfare of occupants. This most visible part of a building, when it comes to performance, is an enigma. To counter this, CBE researchers are working on multiple efforts to create new facade tools and metrics, and to document examples of excellence in terms of facade performance.

An Improved Index for Evaluating ‘Long-Term’ Comfort with Continuous Monitoring

An international team of researchers led by CBE has devised a new method for evaluating thermal comfort inside buildings over extended periods of time. The new index, one of many created and tested by the team, has been demonstrated to be a significant improvement over existing indices being used in building design and operation.

Tool Builder Carlos Duarte Joins CBE as Post-Doc Researcher

Already a core part of CBE’s research team, Carlos Duarte completed his PhD dissertation earlier this year and has joined CBE as a post-doctoral researcher. We caught up with him via Zoom while the campus is still closed due to the ongoing concerns of Covid-19.

New Comfort Classifications Acknowledge Human Variability and Encourage Occupant Control

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.

Protest against police violence

Sustainability Means Justice

We are saddened by the deaths of George Floyd, Breonna Taylor, Ahmaud Arbery and countless other innocent Black lives at the hands of police and vigilantes. We share the outrage that has been erupting in demonstrations in all 50 states and around the world, and we recognize that systemic racism leads to unequal access to economic opportunity, health outcomes and environmental justice. As sustainability professionals, we can catalyze change by leveraging our skills as designers, builders and planners, and by striving to diversify our profession.
