MEDFORD ANDREWS MIDDLE SCHOOL HVAC ELECTRIFICATION
MEDFORD, MASSACHUSETTS
CHALLENGE
B2Q has been working with the City on resiliency and energy conservation projects in this and other facilities since 2016. In 2023, B2Q was retained by the City of Medford to evaluate HVAC equipment replacement options for the 104,000 square foot Andrews Middle School, serving grades 6-8. The major HVAC equipment had failed or was approaching the end of its useful life, presenting an opportunity to study replacements that considered decarbonization. The focus was on potential energy and emissions savings and providing study-level estimates for probable construction costs.
OPPORTUNITY
B2Q analyzed two replacement options: an in-kind replacement and a practical electrification solution utilizing air-source and air-to-water heat pumps to reduce natural gas use and carbon footprint. Custom spreadsheet models were developed to estimate energy performance, and a professional cost estimate was obtained to assist the City in making an informed decision.
RESULTS
The study presented two viable HVAC replacement options, with the electrification option offering significant potential to reduce natural gas usage and carbon footprint. B2Q was selected for the design phase of this project, which was completed in spring 2025. The project is currently under construction is expected to be complete by Fall 2025.
