MEDFORD RESILIENCY PROJECT
MEDFORD, MASSACHUSETTS
CHALLENGE
B2Q Associates 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
as obtained to assist the City in making an informed decision.
RESULTS
The study presented two viable HVAC replacement options, with the practical electrification option offering the potential to reduce natural gas usage by over 50% and carbon emissions by nearly 40%. These findings supported the City’s decision-making process and led the City to pursue the next steps for the practical decarbonization replacement option. B2Q has been selected for the design phase of the project, which is expected to be complete in 2025.
