The following is a step-by-step overview of the audit process:
1. Our audit team/Energy Engineer will create an inventory of all “dusk to dawn” outdoor lighting
using information provided by staff members who process monthly bills and energy provider
invoices and those who are responsible for the maintenance of said facilities. We will also
request an inventory file from Eversource or the City in Excel format, which will form the basis
for the field audit of the majority of unmetered street lights. The remaining lights not on the
inventory, as identified by City staff, may include decorative lighting, flood lights, spot lights, or
wall pack lighting. Some lights will be metered and others will be unmetered and billed, on just
a few or many separate accounts. Once existing inventory is compiled, a field verification of
each street light is completed by the audit team. This survey will include several teams of
individuals in order to complete the system-wide data collection effort in approximately 30
days. A subcontractor, CDM Smith, is proposed to complete the field audit.
2. A complete list of all feasible Energy Conservation Measures (ECM) is developed by the Energy
Engineer from the survey results.
3. Utility and operational savings are calculated by the Energy Engineer for each measure.
