Pressure independent control valves proved to be a key in wringing the benefits out of smartly managed chilled water temperature, but that wasn’t all. Airside energy recovery, desiccant dehumidification to eliminate reheat in operating room environments, and upgrading to ECM fan systems have all contributed to this hospital’s fiscal wellness.
For a building program to be successful and sustainable, it must include an operating budget as well as a construction budget. Fifteen to 20% of the total cost of a building is first cost, and that remaining 80% or more is in the operation of the building over its life.

The ongoing human and financial tolls taken by these infections point to the need for engineers and facilities to raise their IAQ game wherever possible. Move beyond the minimum and get into the what, where, and how of HEPA filtration, ultraviolet technology, and catalytic air cleaners.
Beginning with whether or not a drive is even needed, the article moves on to help you clear hurdles involved with motor compatibility, existing starters, drive reliability, controls integration, and more.
Critical facility HVAC and indoor air management is not all alike! In doing my homework for writing this column on critical facilities, I have been struck by the precision of IAQ monitoring in data centers.
