The comprehensive energy project with Milton Academy, designed and engineered by Bluestone, was recently featured on Banker & Tradesman. From the article:
Norwell-based Bluestone Energy Services LLC has upgraded mechanical, controls and lighting systems at Milton Academy to improve energy efficiency throughout the college preparatory boarding and day school’s campus.
Bluestone replaced Milton’s existing pneumatic controls system and installed digital controls to the HVAC system including air handling units (AHUs), chiller and heat exchangers. Bluestone also installed variable frequency drives (VFDs) on AHUs and water circulation pumps.
The efficiency project will save Milton over one-million kilowatt hours, 31,000 therms and 1,800 gallons of oil annually, while yielding slightly over a two year ROI, as well as electric and gas incentives from NSTAR and National Grid of nearly $400,000.
In addition to the main goal of energy savings, Bluestone’s lighting design focused on standardizing lighting technologies and color temperature. Over 5,000 fixtures were retrofitted to High Performance T8 (HPT8) technology. Additionally, LED lighting was installed in all exterior wall packs and decorative post tops. Dual technology sensors installed throughout the campus now allow for lights to switch off in unoccupied areas.
