Evaluation Reports - Final and Draft Reports

Evaluation Reports and Studies

As required by statutory mandates, regulatory orders, and policy directives, the Energy Efficiency Board conducts evaluation studies and market research to ensure that the energy efficiency programs supported by the Connecticut Energy Efficiency Fund are cost effective and achieve optimal levels of energy savings. Below please find final and draft versions of the EEB evaluation reports and studies, along with related documents such as project descriptions, stakeholder comments and supplementary materials. Documents are organized in reverse chronological order, with the newest documents listed first.

The Energy Efficiency Fund also participates in joint research and evaluation projects undertaken by the Northeast Energy Efficiency Partnership (NEEP) Evaluation, Measurement and Verification Forum. Information on these projects may be found here. For information concerning the ongoing activities of the EEB Evaluation Committee, including monthly meeting documents, multi-year plans, reports to the legislature, and the Roadmap under which it operates, please visit the the Evaluation Committee's page here.
