Challenge

Of the total 468,100 SF of this primarily manufacturing/distribution project, 21,600 SF was allotted to office space, and 43,000 SF of shell space. Unique ventilation for the coffee roasting process was needed, as well as efficiency solutions for the staff areas.

The VHV team was tasked with finding energy saving options for the following needs of such a facility: a high volume of chilled water, an efficient heating plant, and dehumidication systems to allow the plant to produce high quality roasted coffee beans.

Solution

The project included a 900 Ton water cooled centrifugal Chilled Water plant with 100% economizers, a 12,000 MBH heating plant, a custom air distribution HVAC systems totaling 187, 750 CFM capacity, Liquid Desiccant Dehumidification systems to dehumidify to Low Relative Humidity (RH) specification of <30% RH at 70ºF for specialty packaging areas, a 650 HP High Efficiency Compressed air system, Recuperative Thermal oxidizers, and a specialty Coffee Process De-gas ventilation system.

The systems VHV Company designed and installed has a calculated Annual Electrical Savings of 4,468,336 kWH and Annual Natural Gas Savings of 1,751,390 CCF when compared to the Vermont State Energy Code baseline and conventional systems.

Ultimately, VHV calculated a total Operating Cost Savings of over $2 Million each year.
