Morton Grove, Ill. — Xylem Inc. has released a video case history (http://www.youtube.com/watch?v=M4bkIP-nPGM) detailing how an innovative Bell & Gossett variable speed system helped the Monarch Centre in Atlanta become an award-winning building.
Featuring interviews with the engineers who designed, installed and maintain the innovative variable speed pumping system, the video case history chronicles how an inefficient chilled water system was retrofitted into an energy-efficient “star.”
Constructed in 1983, the Monarch Centre consisted of a very big “energy” hub, according to chief building engineer Ralph Kowalke. The two condenser pumps and two chilled water pumps were inefficient and had trouble servicing the two chillers and providing a reliable supply of water to the top floor.
Engineers from James M. Pleasants Company, Xylem’s local Bell & Gossett representative, worked with the consulting mechanical engineering firm to replace the chillers with a primary secondary variable speed pumping system.
Travis Palladino, sales engineer with James M. Pleasants Company explained, “There are always challenges involved in retrofit chilled water projects. There are space concerns and proper selection of equipment. Working with the local engineering team, we agreed that the Bell & Gossett series 1510 base mounted end suction pump was the best pumping solution for this project.”
The results – Monarch Centre won the Energy Star Award in 2011 and received the coveted LEED Silver Certification in 2012. The video case history, part of the Bell & Gossett Solves It series, provides greater detail on how they achieved this.
