Happy New Year from Building Technology & Urban Systems


As we begin a new year already filled with bright prospects for advancing smarter, more efficient buildings, it’s worth reflecting on many noteworthy developments from late last year. Researchers at Berkeley Lab’s Building Technology & Urban Systems (BTUS) Division have contributed foundational, important research and guidelines that are helping organizations across the U.S. and around the world to save energy, avoid carbon emissions, and improve indoor air. 


A framework for reducing greenhouse gases in building portfolios was named among the most valuable decarbonization guides for 2024, while the Building Efficiency Targeting Tool for Energy Retrofits (BETTER) put a nonprofit in Massachusetts on a path to nearly $2.5 million a year in energy cost savings. And what began as a pandemic response to improve energy efficiency and indoor air quality in schools is now an established Department of Energy (DOE) program, Efficient and Healthy Schools, which officially launched last November. 


Read on for more news and accolades from BTUS, including an opportunity to nominate exemplary small commercial building controls projects for heating, ventilation, and air conditioning (HVAC) units as part of the Smarter Small Buildings Campaign.

The framework provides guidance to organizations on reducing greenhouse gas emissions for their building portfolios and vehicle fleets. BTUS’s Hannah Kramer, Nora Hart, and Jessica Granderson are coauthors of the framework, which offers both near-term actions and a longer-term transition path to low- or no-carbon operations.

Berkeley Lab Delivers a ‘BETTER’ Approach to Decarbonizing Underserved Buildings in New England


The Building Efficiency Targeting Tool for Energy Retrofits (BETTER) is enabling major cost and emissions savings for Massachusetts. PowerOptions, a nonprofit energy consortium, has been using BETTER, which was developed by Berkeley Lab and Johnson Controls, since January 2023 to conduct virtual energy efficiency audits for over 50 buildings from eight nonprofit organizations. BETTER enabled PowerOptions to avoid on-site energy audit costs, save time, and provide roadmaps that will help its members cut energy costs by $2.48 million and avoid emissions equivalent to 6,560 metric tons of carbon dioxide each year. To learn more, see the full case study or visit BETTER at https://better.lbl.gov/


The DOE Building Technologies Office’s BETTER is an award-winning software toolkit that delivers actionable insights to improve energy, emissions, and financial performance in buildings and portfolios without requiring site visits and complex modeling. Since its launch in 2021, BETTER has 1,100 registered users that have analyzed more than 12,000 buildings covering 2 billion square feet of floor space in more than 60 countries.

Efficient and Healthy Schools Program Launches


Efficient and Healthy Schools, which began as a campaign in response to the coronavirus pandemic, has been formalized as a DOE program, the agency announced last November. The program provides recognition and technical assistance to school districts seeking to implement high-impact indoor air quality and efficiency improvements. Efficient and Healthy Schools has also released its 2023-2024 Recognition Award Categories and application support. Berkeley Lab provides technical support for the program, which is an interagency effort from the Department of Energy, Department of Education, and the Environmental Protection Agency (EPA). Read about the growing network of schools and districts applying for recognition. If you would like to provide support, please sign up as a supporter or encourage schools to sign up as a participant.

A Milestone for IMPEL: 2024 Marks Fifth Anniversary!


Five years ago, the IMPEL program began by supporting five DOE National Lab teams through an incubation and industry mentorship process, where each team learned to communicate the value of their R&D to broad audiences. Today, IMPEL has vastly expanded its programming to entrepreneurs and researchers, providing coaching, mentoring and public and private sector opportunities that connect innovators to potential investors, partners, and policymakers. It serves critical needs of building technologists at the national labs and beyond, springboarding over 250 innovators from small businesses, nonprofits, and academia into countless success stories.


This year, IMPEL’s Berkeley Lab-based project team is developing a research publication describing front-line perspectives from emerging technologists, investors, and researchers, with insights from the past five years. The paper will explore the barriers building tech faces when going to market and propose new approaches for commercialization programs moving forward. If you would like to get involved with our research publication, contact us at IMPEL@lbl.gov.

FEATURED PUBLICATIONS

Getting Beyond Widgets: Performance of Efficient Indoor Air Quality System Retrofit Packages for Schools


Last November, BTUS researchers published a report on the results of retrofit packages in primary schools. The report is the latest from the Beyond Widgets program, which advances systems-based retrofit approaches rather than those that tackle one component at a time. In Getting Beyond Widgets: Performance of Efficient Indoor Air Quality System Retrofit Packages for Schools, researchers evaluated integrated system packages for two climate zones: Northern California and North Carolina. They compared baseline and retrofit whole-building annual energy simulation results, looking at annual savings on energy use and demand, utility costs, and carbon emissions. The report found that energy and carbon emissions savings were greater for the higher-cost, more comprehensive retrofit packages, with impacts ranging from 13% to 35% energy savings.
