Had a unique opportunity to recently tour mechanical spaces of the new McGlothlin Medical Education Center on the Virginia Commonwealth University campus, and I thought you guys might like to see some of the "big stuff" they are using. This is a nearly complete, 12 story, approximately 200,000 square foot building that will contain classrooms, auditoriums, offices, and operating room simulation rooms. It is LEED Silver certified. Primary air is supplied by 3 Large Semco Pinnacle Primary Ventilation units. Each unit contains supply and exhaust fans with VFDs, and energy wheel, dehumidification wheel, chilled water, hot water, and steam coils. Cooling is provided by 3 Carrier Evergreen Chillers, also with VFDs. Steam is provided by a central steam plant that also supplies steam to the rest of the downtown campus, while I believe the water is heated locally. Terminal heating and cooling is provided by radiators and chilled beams. Kudos to all who were involved with this project! Excited to see the place open this Spring!

Here's one of the large auditoriums. Projected images will be provided by 2 projectors, blended into one image. Each student is provided a microphone, power and ethernet ports for laptops.

Varoius views of the 3 Primary Air Handlers. Note the composition notebook filter logbook in the last picture As a reference for size, each access door is about 6 feet high.

Blurry, but here is an inside look at the energy wheel.
