Lakeville data show large drop in municipal energy intensity since 2011; schools and animal shelter highlighted as priorities
Summary
Townwide energy intensity as reported from the Massachusetts Energy Insight portal declined roughly 50% from the 2011 baseline to fiscal year 2024, the Energy Advisory Committee reported Nov. 3 while recommending the town's Green Communities annual report to the town manager.
Town energy metrics reviewed by the Lakeville Energy Advisory Committee on Nov. 3 showed substantial improvements in building-level energy utilization intensity (EUI) since the committee's 2011 baseline, while also identifying remaining priorities.
Using the Massachusetts Energy Insight (MEI) portal, committee members examined a set of standard metrics used by Green Communities reporting. The MEI-derived townwide EUI (energy use intensity, energy per square foot) was roughly 40 in the 2011 baseline and had fallen to a little over 20 by fiscal year 2024, a decline the committee characterized as significant.
The committee reviewed fuel-type trends and building-level details. Committee members noted a substantial decline in oil consumption and overall energy use per square foot, attributed to measures such as improved building envelopes, LED lighting and the phased adoption of heat pumps. At the building level, the animal shelter stood out for having a high EUI (inefficient energy use per square foot) while the regional school campus accounted for the largest total energy cost and the highest CO2 emissions; schools were heated primarily with fuel oil.
Committee members discussed data quality and audit practices for the portal. Members asked that electricity and fuel inputs be validated against invoices, gallons and account-level meters so that decisions and grant applications are based on consistent measures. The MEI portal provides account-level detail the committee said should be used to prioritize projects.
The committee reviewed and approved the Green Communities annual report (due Nov. 7). The committee voted unanimously to recommend the report for submission to the town manager; the report documents town progress against energy-reduction commitments and will be filed as the town's Green Communities annual submission.
Committee members agreed next steps: prioritize energy-efficiency measures at high-EUI facilities (animal shelter), pursue opportunities that can reduce the school district's fuel-oil dependence, and maintain MEI data validation as part of project selection and grant work.
Speakers quoted are drawn from the Nov. 3 meeting transcript.
