Observations from the Lawrence Berkeley National Laboratory’s FLEXLAB

By Hannah Greinetz

Hannah Greinetz is the Managing Editor of the Meeting of the Minds Blog. She holds a BA in Anthropology from UC Santa Cruz and an MBA in Sustainable Management from Presidio Graduate School.

The Meeting of the Minds conference this year was a stimulating gathering of thought leaders, city leaders, and change makers, held in Richmond, California’s historic Craneway Pavilion. The agenda of esteemed speakers covered everything from Singapore’s NEWater strategy, to the strategy behind creating a sustainable economy in Detroit, to digital currencies and affordable housing in Vancouver.

During the afternoon of October 21, conference attendees broke out into groups and boarded the buses waiting outside to take them to afternoon breakout sessions, one of which was a tour of UC Berkeley’s FLEXLAB facility focused on how we can reduce energy consumption of commercial buildings.

The Lawrence Berkeley National Laboratory’s FLEXLAB sits high in the hills above the UC Berkeley Campus and exists to address the fact that a staggering 40% of our electrical energy use is by commercial office buildings. In 2012, with $15.9million in funding from the U.S. Department of Energy (DOE), Berkeley Lab broke ground on a flexible design test bed for building efficiency technologies. FLEXLAB derives its name from the purpose for the research being conducted there: Facility for Low Energy eXperiments in Buildings; the test beds there test the efficiency of HVAC, lighting, windows, building envelope, control systems, and plug loads, in any combination.

As we filed off of the buses, our backs to a stunning view of Oakland, Berkeley, and San Francisco, we approached the four buildings that make up the test beds at FLEXLAB. There are two identical buildings with interchangeable siding and south-facing windows that are designed to let users test drive a technology side by side and monitor the results. A third building is mounted on a 270 degree rotating cement slab that can control for the position of a building’s windows or capture data from the windows or PV panels from different angles. Each of the buildings is outfitted with about 2,000 sensors to monitor things like heat, moisture, glare, and temperature. The buildings are designed to test different components of a building that impact its energy use, and by testing them at FLEXLAB, with its 6,000+ sensors and data analysis, builders and developers can be sure that they’re installing the optimal mix of windows, HVAC, solar PV, and even desks and carpets, to ensure peak efficiency.

Real Time Experimentation

In the first private sector installation at FLEXLAB, Webcor Builders installed the siding, windows, ventilation systems, lighting, and even the desks they planned to use in Genentech’s newly constructed 250,000 square foot office building in South San Francisco office. The test beds at FLEXLAB enabled Webcor to mock up the components of the Genentech building and test the combination and design before they started building. The series of tests was designed to enable decision making on shading and lighting components of the building; they also used the rotating test bed to test three different potential orientations of the building.

As a result, Webcor was able to maximize the efficiency of space in the building, and minimize glare, maximizing comfort at workstations near the windows. Although FLEXLAB was just opening its doors and Webcor was relatively close to breaking ground on the new Genentech office when the tests were conducted, the FLEXLAB project was still able to add great value to the Genentech building in finding the best management practices of shading and light controls.

Berkeley Lab’s Global Partnership Alliance

For the second segment of our visit, the Meeting of the Minds group engaged in discussion with the founder of the Global Partnership Alliance (GPA), Rahul Chopra. Rahul introduced our group to the driving ideas behind GPA: “to standardize, commercialize, and monetize energy efficiency in buildings, creating new investment opportunities that will drive deep cuts in building energy use.” He then asked the group for our thoughts on how we can bring private ideas and investment dollars in to capitalize on the $290billion market opportunity that commercial energy efficiency represents, and with a room full of business minds and thought leaders on the subject, a lively discussion ensued.

Rahul seeded the conversation with ideas of how buildings can act as part of the interactive energy ecosystem, asking: ‘how can buildings influence the grid in a positive way? Electric vehicles, microgrids, energy storage, solar PV, and productivity data are all aspects of the answers that GPA is considering. The conversation also centered around how new market initiatives will enable the monetization of building energy efficiency, especially without government incentives. Ideas around the renaissance of REIT capital prompted discussion of a rooftop REIT, separate from the assets of the building. The large market for efficiency data analytics also came into play in a discussion around data sharing and metrics for success that investors will be able to use to guarantee performance and energy savings on capital invested into building efficiency.

GPA is seeking to bridge the gap between the technologies being tested at FLEXLAB, and successfully monetize and bring them to the market via public-private partnerships and new market mechanisms. Today, they’re working on creating guarantees for performance to reduce project performance risk in building efficiency investments; integrated building management systems; and creating IBOS, a standardized operating system for smart buildings that will be able to collect data, control operations, and create data analytics to open up further possibilities for innovation in how buildings perform.

Spotlighting innovations in urban sustainability and connected technology

Researcher and Paratransit Operator Collaboration in South Africa

Meeting of the Minds took a few moments to talk with Herrie Schalekamp about new working relationships between researchers and paratransit operators in South Africa and beyond. Herrie is the ACET Research Officer at the University of Cape Town’s Centre for Transport Studies. In addition to his research, teaching and consulting in the fields of paratransit and public transport reform he is involved in specialised educational programmes for paratransit operators and government officials. Herrie’s activities form part of a broader endeavour to investigate and contribute to improved public transport operations and regulation in Sub-Saharan African cities under ACET – the African Centre of Excellence for Studies in Public and Non-motorised Transport.

Leveraging Big Data & Analytics to Revitalize Brownfields

Brownfields are sites that are vacant or underutilized due to environmental contamination, real or imagined. There are brownfields of some kind in virtually every city and town in the U.S., usually related to a gas station, dry cleaner, auto repair shop, car dealership or some other ubiquitous local business that once benefited the community it now burdens with environmental hazards or old buildings.

In addressing this issue, technology has not been effectively deployed to promote redevelopment of these sites and catalyze community revitalization. We find that the question around the use of technology and data in advancing the redevelopment of brownfields is twofold:

How can current and future technology advancements be applied to upgrade existing brownfield modeling tools? And then, how can those modeling tools be used to accelerate transformative, sustainable, and smart redevelopment and community revitalization?

New Public and Private Funding Strategies for Urban Parks

Across the country, urban parks are enjoying a renaissance. Dozens of new parks are being built or restored and cities are being creative about how and where they are located. Space under highways, on old rail infrastructure, reclaimed industrial waterfronts or even landfills are all in play as development pressure on urban land grows along with outdoor recreation needs.

These innovative parks are helping cities face common challenges, from demographic shifts, to global competitiveness to changing climate conditions. Mayors and other city officials are taking a fresh look at parks to improve overall community health and sense of place, strengthen local economies by attracting new investments and creating jobs, help manage storm water run-off, improve air quality, and much more. When we think of city parks holistically, accounting for their full role in communities, they become some of the smartest investments we can make.

Meeting of the Minds is made possible by the generous support of these organizations.
