After the cooperative replaced its 1963 original electric chiller with three gas-fired units in 2009, Hurricane Irene flooded the mechanical room in 2011, destroying all three of the new units.

Less than a year later, Superstorm Sandy hit the co-op hard, flooding the lobby, mailroom, mechanical room, and the practically new replacement chillers.

Given the increased threat of severe storms, the board had the replacement chillers installed on the roof, out of immediate harm’s way.

• Two new double-effect chillers (which supply back up heating in the winter) installed on roof
• Gas and electrical lines routed from mechanical room to roof level to service chillers
• Supplemental structural steel beam assembly installed on roof to support the new chillers
• Existing boiler, pumps, and electrical equipment repaired
• Project was completed within a tight timeframe so the chillers would be ready by the summer cooling season.
