At its meeting on Aug. 27, the School Building Committee approved the installation of a geothermal HVAC system as part of the new high school.
The system was chosen for its high energy efficiency, reduced operational costs and environmental benefits. This meeting is part of the process for building a new school, which may qualify for partial reimbursement through the Massachusetts School Building Authority.
Traditional HVAC systems, in contrast to geothermal systems, often rely on fossil fuels or external electricity for operation. These conventional systems generally involve burning gas or oil or using electricity to power compressors and fansand can result in higher energy consumption, increased operational costs and greater carbon emissions. Traditional systems also require more maintenance and have a shorter operational lifespan compared to geothermal systems.
In contrast, the geothermal system is expected to be 30% more efficient than traditional HVAC systems and has a lifespan of over 50 years. It utilizes the Earth’s stable underground temperature for heating and cooling, leading to zero onsite carbon emissions. The system may also be eligible for incentives under the Inflation Reduction Act (IRA).
The meeting also covered other aspects of the new high school project. The current high school, which has been operational since 1972, is smaller than current regulations require and has issues including overcrowding, insufficient windows and traffic flow challenges.
The committee discussed constructing a new access road behind the middle school to manage traffic flow better. It would run perpendicular to the middle school’s access, along the opposite side of the school. This road is eligible for MSBA reimbursement, and a traffic study is scheduled for September or October to evaluate its feasibility.
Additionally, the committee considered installing two multi-purpose fields and the use of synthetic turf. However, members requested a cost analysis and information on the longevity of synthetic turf before making a decision.
The committee reviewed the N3 layout design for the new high school, a combination of the first two proposed layouts, N1 and N2. This hybrid solution includes a second entrance near the Special Education classrooms, an accessible elevator, and twin courtyard spaces with secure entrances. The three-story design aims to increase parking and field space, improve navigation, and promote community interaction. A walkability study will be conducted to assess these elements. The next step involves presenting the N3 layout to the MSBA for review and approval.
The committee’s focus is on creating a new facility that meets current educational standards and addresses the deficiencies of the existing high school. By adopting a geothermal HVAC system and planning for improved infrastructure and accessibility, the committee aims to deliver a sustainable and functional learning environment.
