More than ten years ago the California Energy Commission (CEC) and California Public Utilities Commission (CPUC) established aspirational goals of Zero Net Energy (ZNE) for all new residential construction by 2020 and all new nonresidential and highrise residential construction by 2030 with half of existing buildings being renovated to ZNE by 2030.
Over the past decade these goals have evolved and the steps to achieve them have been discussed, debated, and fleshed out. The definition and implementation path for ZNE, the metrics to be employed, and role of the electric grid and utility infrastructure have all evolved over time and continue to evolve. More recently, awareness has grown that ZNE is not a goal in itself, but simply a step towards deep reductions in greenhouse gas emissions. Decarbonization of the California economy is now seen as essential to achieving the state’s 2050 greenhouse gas targets.
A group of exceptional speakers discussed topics related to state policy as well as building design and operations essential to moving to ZNE and beyond toward an efficient, low-carbon California. Read more
A new suite of free and publicly available online resources have been launched to facilitate academic and professional studies of thermal comfort in buildings, the result of a four-year effort led by the Center for the Built Environment at UC Berkeley and the University of Sydney’s Indoor Environmental Quality Laboratory. These tools can be used to inform questions about thermal comfort, and to encourage the design of climate-responsive and comfortable low energy (and ZNE) buildings. Read more

It’s exciting when we have the opportunity to experience new sustainable buildings first hand. Last week, while attending the CHESC conference at UC Santa Barbara, along with other attendees I stayed in newly completed student housing designed to meet LEED Platinum standards. While these attractive new buildings exhibit many sustainable features, at times the natural ventilation scheme was not sufficient to maintain comfortable conditions, especially when it was necessary to lower blinds for privacy, or to close windows to block noise from the street and some late night volleyball games.
However, a simple and cost-effective addition to these units would have kept us all comfortable: ceiling fans. CBE research has quantified what we all know intuitively, that fans can provide acceptable comfort at temperatures that otherwise would be stifling. This enables passive solutions in milder climates, and may reduce the reliance on air conditioning in climates where passive solutions alone are not sufficient. Read more

Engineers have a reputation for complicating things, but the folks at PAE like to keep it simple: People and nature are the driving forces behind their work, both inside and out. PAE designs high-performing buildings that keep people comfortable, healthy, and productive inside, while restoring the natural world outside.
This approach makes PAE an ideal partner for CBE’s industry consortium. As Principal Alan Shepherd points out, “We are excited for the opportunity to be kept abreast of the latest research in occupant comfort and wellbeing, and let this information inform and inspire our designs, as well as help our firm’s up-and-coming engineers learn.”
This April, CBE welcomed to its consortium Sanken, a Japan-based engineering leader that will collaborate with researchers at CBE and overseas on radiant cooling technologies. This new collaboration builds on Sanken’s efforts that span several decades to innovate and provide customers with reliable and advanced systems and facilities. Read more
