Brooks School

Investing in an energy-efficient campus—proactively

Brooks School took a proactive approach to finding energy-efficiency savings on its small campus in North Andover, MA. GreenerU has helped with finding creative solutions and innovations to this top-notch boarding school.


GreenerU began its relationship with Brooks School in 2012, when the school was looking for help with a technical assistance study to find energy-efficiency opportunities for Luce Library. GreenerU found multiple opportunities for energy efficiency, coming up with a plan and financial incentives to replace an outdated chiller and outdated pneumatic controls, and to upgrade lighting. The project led to substantial energy savings for Brooks, reducing building energy costs by $38,000 annually. GreenerU has assisted Brooks in subsequent investments in reconstructing its ice rink and performing ongoing commissioning and optimization of its equipment for continued energy savings.

With outdated heating, air conditioning, and ventilation equipment, Brooks had an opportunity to leverage utility incentives and realize substantial energy savings through new equipment.

In 2016, in partnership with Consigli Construction Co., Brooks began planning its brand-new Center for the Arts and has involved GreenerU in all mechanical and electrical aspects of the design, including a steam system relocation. Using the 3D modeling capabilities of BIM 360 software, in partnership with the project’s architects and building engineers, GreenerU assisted in the design an energy-efficient system for a new building from the ground up, and managed the installation of these systems as well.

When the state-of-the-art Brooks Center for the Arts building opened in Fall 2018, students have enjoyed a well-lit, thoughtfully constructed space worthy of their talent.

Campus Improvements

  • HVAC optimization
    Like any equipment, heating/ventilation/air conditioning systems for a building need adjustments from time to time.
  • Chiller upgrades
    Chillers providing comfort cooling can be updated with optimized controls systems or replaced with newer, high-efficiency models.
  • Lighting
    Transitioning to LED lighting is one of the most effective ways of reducing energy costs on campus.
  • Building automation system
    Building automation is the automatic centralized control of a building's heating, ventilation, air conditioning, lighting, and/or other systems.
  • Ongoing commissioning
    Ongoing commissioning, also called continuous commissioning, is an integrated, data-driven approach to building performance optimization.
  • Retrocommissioning
    Retrocommissioning is re-tuning an existing equipment to bring it back into optimal working order.
  • Water conservation
    Wasted hot water can result in high energy bills. Installed water conservation measures can help reduce energy use.
“GreenerU has continued to deliver a knowledgeable approach to finding the best solutions for Brooks School, as opposed to just replicating a solution developed for another institution.”
