When the Univ. of California, San Diego (UCSD) embarked on the construction of its 196,000-sf Health Sciences Biomedical Research Facility, the priority was to support collaborative teamwork and a “project-first” approach to delivering an on-time, high-quality, high-performance building that met LEED certification goals.

Sustainable renovation in energy-intensive lab while improving EH&S: Otto Maass Chemistry Building, McGill Univ.December 5, 2013 1:39 pm | by Pierre-Luc Baril, LEED AP BD+C | Comments
The Otto Maass Building, built in 1964 and located on the McGill Univ. campus in downtown Montreal, is dedicated to education and research in chemistry. The total gross floor area is 140,000 sf of which 60% are labs. With an average fume hood density of around ten chemical fume hoods per 5,000 sf, this building was, in 2008, the biggest energy user of the campus.
Vacuum is such a common utility for most labs and is an important influence on the achievement of sustainability objectives. Studies indicate that vacuum pumps can represent 15% or more of the plug loads in labs. If you can significantly reduce energy use by vacuum pumps, you can make an important dent in total lab building plug loads.
This presentation summarizes the NZ4 Global Alliance’s Closed-Loop Science Park Prototype design and describe how this can be used for a regional stimulus to create economic, educational and environmental sustainability. The presentation describes a public-private partnership process which is suggested as the most positive way to implement this economic stimulus and continue U.S. advancement in technology.
Celgene’s 115,000-sf Warm Core and Shell Laboratory Tenant Improvement project in San Diego, Calif., had its challenges right from the outset—beginning with the owner implementing a design-bid-build method to maintain control of the design. The design and construction time frame was extremely compressed with 11 weeks from start of design development to the issued for permit set.
With the title “Fume cupboards – Part 7: Fume cupboards for high heat and acidic load” the seventh part of the European series of EN 14175 standards was issued in 2012. The new standard focuses on fume hoods for special applications, including a high heat and/or acidic load. These special applications require additional design, safety, operating and maintenance properties.
This abstract addresses designing high-performance labs with a goal of over 50% energy-usage reduction. The speakers present a case study of the Univ. of Kentucky’s Center for Applied Energy Research (CAER II), a 43,156-sf research building which allowed CAER to expand its research opportunities in the fields of biomass and biofuels, solar energy and electrochemical power sources (capacitors and batteries).
Like most higher education institutions across the country, lab operations at the Univ. of Michigan (UM) consume approximately four to twelve times more energy compared to a classroom or office environment, providing rich opportunities to save on energy utilities and resources.
Many authors have discussed the savings in reducing lab exhaust fan energy. Variable-volume systems and implementation of night setback may provide significant savings. One limitation that has been cited is the need to maintain a safe level of dispersion from the exhaust stacks, to avoid negative impacts at intakes on or near the lab.
When ventilated cages were introduced, they brought forth the promise of improved animal welfare, better protection for animals and technicians, and, labor savings, by increasing the days between cage changes. Present ventilated cage designs have fulfilled these promises. But, can they further reduce labor and energy use?
Western architects typically bring the full measure of familiar technology to bear on lab design in developing countries. Design of a pharmaceutical quality control lab has its challenges. Placement of that lab in a country with limited resources in a tropical climate presents additional challenges. AECOM met these by incorporating sustainable features into a building in response to environmental and economic factors impacting design.
Guidelines and standards for minimum air change rates in labs and vivariums have changed over the last few years. More than 10 years ago, minimum air change rates were commonly set prescriptively at 8 to 12 air changes per hour (ACH). However, with increasing concerns over rising energy costs, the pendulum on air change rates swung to lower prescriptive rates to 6 ACH.
Energy audits and energy models play a critical role in providing the design team with important insight about how an existing building is operating. Energy audits and models also allow the team to evaluate retrofit feasibility and potential energy-conservation measures (ECMs). However, a lack of audit process standards means that incomplete or inaccurate data is sometimes collected.
Since the advent of fluorescent lighting and air conditioning, our interior lighting and temperature environments have become almost completely artificial. Only recently has the design imperative of “sustainability” caused the architectural community to reconsider the human impacts of these artificial environments, and attempt to restore a more natural, efficient and beneficial interior environment.
In the pursuit of more sustainable construction practices, advanced materials and design techniques have led to lighter and more flexible structural systems in buildings. These lightweight systems are unfortunately more susceptible to structural vibration generated from both internal and external sources.
This white paper discusses lab exhaust energy conservation. The most common system has the operating fan running at 100% of design volume while the standby fan is off and shut off by a backdraft damper. However, significant energy savings can be achieved by running both the operating fan and the standby fan together, each at 50% of design flow.
