West Hill Energy & Computing

What West Hill Energy & Computing does

West Hill Energy & Computing (WHEC) is a privately-held, founder-operated energy efficiency consulting firm headquartered in Brattleboro, Vermont, in continuous operation since 1991. The firm provides impact evaluation, monitoring and verification (M&V), statistical analysis, and training services to utilities, state energy efficiency program administrators, and energy service companies. WHEC's work focuses on quantifying savings from energy efficiency programs and diagnosing why projected versus actual savings diverge, supporting regulatory compliance such as ISO New England Forward Capacity Market verification and program effectiveness assessments for clients including Efficiency Vermont, NYSERDA, Con Edison, Vermont Gas Systems, and Burlington Electric Department.

WHEC's technical foundation combines applied statistical methods—multivariate regression, cross-sectional time-series panels, discriminant analysis, and consumption analysis using monthly bills or interval data—with proprietary methodological innovations pioneered by co-founder Kathryn Parlin. These include information-theoretic model selection based on Aikake's Information Criteria for residential billing analysis, the Barriers Approach developed for NYSERDA to quantify program influence by measuring adoption barriers, an Analytic Hierarchical Process method for attribution under development, and a hybrid billing/engineering algorithm for residential heating equipment savings. The firm has authored numerous peer-reviewed papers presented at conferences including IEPEC, ACEEE Summer Study, and American Statistical Association meetings, which serve as both thought leadership and client acquisition.

The firm operates on a project-based professional services model with custom pricing per engagement, functioning as both prime contractor and subcontractor. Revenue is generated through consulting engagements (impact evaluation, M&V, statistical analysis, training) sold directly to enterprise and government clients via industry reputation, conference presentations, publications, and direct outreach. The firm maintains a horizontal segmentation strategy targeting three primary segments—utilities, state program administrators, and energy service companies—with no intermediaries, resellers, or external institutional capital. The four-person team is led by co-founders Kathryn Parlin and Al Bartsch, supported by an energy analyst and a project manager, with the website noting coverage of Northeast USA plus engagements in New York and California.
