West Hill Energy and Computing

Providing our Clients with High Quality Evaluation Services

Since 1991 the West Hill Energy and Computing team has been on a mission to provide robust and reliable evaluations of public and private efforts to reduce energy use. The interdisciplinary staff brings the experience and knowledge to implement effective evaluation strategies addressing impact, economic, net to gross and policy issues. The team uses tried and true methods, such as billing analysis and M&V, as well as developing creative approaches to address intractable or unusual issues.

Each principal has over 25 years of experience and specializes in the evaluation, measurement and verification of energy efficiency programs. The evaluations are carefully designed to balance methods and cost, offer precision and comprehensiveness, and meet stakeholders’ needs.

During the past ten years, the firm has focused on providing robust, defensible impact evaluation of both residential and commercial efficiency programs in California, New York and Vermont.

We offer . . .

  • State-of-the art evaluations that are specifically tailored to meet your needs

  • Personalized attention from the principals (many large companies turn the evaluations over to junior staff)

  • Innovative evaluations that can become the source materials for conference papers and presentations

Our clients become our partners in contributing to the national and international discussion on energy efficiency evaluation.
