might have more wet chemistry, imaging equipment, and potentially dirtier processes. Is it important for designers to know which chemicals and processes will be used in a lab? Safety is a conversation between the owners, environmental health and safety (EH&S) professionals and lab planners. Owners employ or contract EH&S professionals who will run the safety program for the lab. Since EH&S authorities are responsible for maintaining safe operations within the facility, they’re the ones who decide how ventilation is used for risk mitigation. These professionals are educated and experienced in chemistry and industrial hygiene and know which protective equipment, procedures and containment strategies are necessary within the labs they oversee. Our role as the consulting engineer is to develop designs for the necessary utilities that allow the equipment they’ve specified to function, including room ventilation rates to promote occupant safety. We deliver designs for utilities and facility systems that fit their specifications. re-heat in current HVAC designs by using a different way of conditioning the air that is substantially more efficient. We’ve achieved performance of 50%+ better than Title 24 minimum standards using this design because the thermodynamic process is inherently less wasteful than traditional VAV systems. It works especially well for labs because it’s flexible to changes in load and temperature requirements. We’re able to heat and cool the air with the 4-pipe VAV system at the zone level. If loads change, it’s very responsive and accommodating. It’s also affordable, we were able to fit this design within our team’s design-build budget for the Ernest E. Tschannen Science Complex at Sacramento State, so it fits within a CSU budget. When that project is operational later this year, it will be a benchmark for the CSU system. You’re an active ASHRAE member and have helped to write some of the same standards we’ve talked about. Why was it important for you to be involved? Engineers participate in ASHRAE because we want to improve the industry, so that our industry and society of engineers, operators, occupants, and owners benefit. This effort is altruistic and represents our interest in contributing knowledge to benefit society. We also want to stay ahead of the industry we’re involved with and exercise our ability to influence the future. You have some amount of control and influence by contributing your knowledge and leading peers in producing updates and new content that eventually becomes published literature. It also helps with credibility and name recognition. If an owner or lab planner opens a book and sees your name in the list of authors, that will give them some reassurance. It’s a small industry and ASHRAE also lets members network with a broad network of peers. Members can get a feel of trends taking off in different markets. What sets the P2S Lab design team apart from other MEP firms? Besides our innovations in outside air and exhaust stack clusters, we’re also leaders in 4-pipe VAV systems, which are pretty cutting edge in application. Not many large-scale labs have used that technology, but it has the potential to really improve energy efficiency. It eliminates wasteful 7
