Laboratory HVAC Best Practices

1
Laboratory HVAC Best Practices
Intensive ventilation requirements and
increasing plug loads make todays laboratories
the single largest campus energy consumer.  The
challenge is to design and operate energy
efficient labswhile still maintaining high
performance, comfort, and safety standards.  This
session presents some of the latest strategies
and best practices for optimizing laboratory
energy performance.
