Laboratory HVAC Best Practices

“Intensive ventilation requirements and increasing plug loads make today’s laboratories the single largest campus energy consumer.  The challenge is to design and operate energy efficient labs…while still maintaining high performance, comfort, and safety standards.  This session presents some of the latest strategies and best practices for optimizing laboratory energy performance.”
