Hoosac Valley Middle-High School (LEED-Gold)

HEA provided mechanical, plumbing and fire protection design for the complete replacement of building systems associated with a $35M full building renovation/addition project for a 170,000-sf middle/high school. The project included on-site renewable energy generation as well as a variety of high-efficiency HVAC, plumbing and electrical systems. It also included a kiosk to inform and educate students about the building’s energy-savings features.  

The design included new high-efficiency condensing boilers, valves, pumps, variable frequency drives, energy recovery ventilators, chilled water equipment, exhaust systems, piping and ancillary equipment as well as new controls and a new building management system. HEA provided all necessary building information modeling services to support the LEED certification effort. Throughout the project, HEA’s engineers worked closely with the project’s architect and the school district to develop M/E/P design options that would meet their goals for sustainability while staying within their budget.

M/E/P design for the laboratories included acid neutralization systems with chemical grade piping systems, natural gas piping to turrets and hoods, a lab water system including reduced pressure zone valve isolation, and emergency eyewash and drench showers with tepid water delivery systems. Fume hoods were installed through the labs and interconnected to roof mounted Strobic exhaust fans equipped with VSDs. A sophisticated control system was provided to control the air valves, exhaust fans and make-up air systems in unison.

Where appropriate, demand-controlled ventilation was incorporated into the air handling equipment so that the outside air volume modulates to match the ventilation needs of spaces with varying occupancies (gym, cafeteria, etc.).

The project, which achieved a LEED Gold certification from the USBGC, also included rainwater harvesting, energy recovery, outdoor air measurement and demand control ventilation, and low flow plumbing fixtures. An NFPA 13-compliant fire protection system was also designed.

The project achieved LEEDTM-Gold status from the US Green Building Council.
