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.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
