Understanding and Tackling the Energy Gorillas on Campus

Labs represent the largest energy use on campus. Harry Stark and Bruce Chamberlain will provide an overview of Cal's efforts to optimize mechanical systems by implementing a variety of strategies across different lab types.


Deirdre Carter (LBNL): Integrated Management of Laboratory Ventilation Systems to Save Energy and Improve Safety

Lawrence Berkeley National Laboratory will present on a new integrated laboratory ventilation management program, which it developed with support from the DOE Smart Labs Accelerator and consultants from 3Flow. The program is managed jointly by Sustainable Berkeley Lab and the Lab's Environmental Health and Safety (EHS) and Facilities divisions.


Steve Taylor (Taylor Engineering): 4-Pipe VAV vs. Active Chilled Beams for Labs

To improve efficiency, modern laboratory HVAC designs focus on two primary goals: minimizing the energy used to condition outdoor air and minimizing terminal unit reheat energy. In this regard, several guides and articles encourage using active chilled beams (ACB) in lab zones. But ACBs are often not the best choice from a cost and efficiency perspective. This presentation discusses an alternative design, 4-pipe VAV (4PVAV) systems, which is often cheaper and more efficient. The presentation will discuss the details of what makes a lab ventilation-dominated, hood-dominated or load-dominated and how these categories help define when ACB or 4-pipe VAV systems can save more energy.

Megan Gunther (Affiliated Engineers Inc.): Evaporative Cooling for Lab Design: Balancing the Use of Energy and Water

Evaporative cooling has proved to be very effective in dry climate zones for reducing mechanical cooling loads. When implemented in moderate dry climates, such as California, it can provide even greater savings by extending the available outside air economizing hours annually. For laboratories requiring 100% outside air and greater cooling demands than low-load spaces, evaporative cooling can have a significant impact on cooling energy and peak demand savings. In these same climates, however, water supply is often at threat. Are we able to balance the trade-offs between water consumption and energy reduction? While evaporative cooling increases water consumption directly at the source, there is an opportunity for both water and energy use reduction when we holistically evaluate our building systems, leveraging the energy:water nexus. This session explores the impact these systems can have on both cooling load requirements and water consumption, demonstrated through two different case studies. With each case, the analysis of evaporative cooling, including the tools used, will be presented.

I2SL Annual Conference recap

Three top Bay Area laboratory leaders shared their presentations from the conference, which was held in Raleigh, North Carolina in October. We learned about the upcoming new I2SL/DOE lab benchmarking tool, the latest in green lab certifications and sustainable procurement, and the mechanical design of an outstanding new, modern laboratory facility. The future of sustainable labs has never looked so great.

September 2018

Hard Hat Lab Tour - Gilead

A hard hat tour of Gilead Sciences, Building NB324. This new 357,000 sf laboratory building, scheduled to open the second quarter of 2019, will include Biology, Drug Metabolism and Pharmacokinetics (DMPK), Drug Safety Evaluation, Medicinal Chemistry, and Structural Chemistry labs. It will also allow Gilead to create a centralized location for research laboratories on its Foster City campus.
