Technical advisory and engineering services for utility energy efficiency programs, from measure development through regulatory defense.
We build savings calculators and analytical engines that utilities and program administrators use to process projects at scale. Our tools handle complex engineering calculations with clean user interfaces, automated QC checks, and documentation that supports regulatory review.
BIN-based energy savings calculators (8,760-hour analysis)
Deemed savings workbooks with permutation engines
Chiller plant optimization tools (CW reset, waterside economizer)
Building envelope analysis platforms (conduction, infiltration, solar)
Weather data processing and psychrometric calculation engines
Automated batch reporting and scenario analysis workflows
We trace savings algorithms across state Technical Reference Manuals to identify gaps, inconsistencies, and adoption opportunities. When utilities need new measures developed or existing measures updated, we produce the engineering analysis and documentation that supports TRM committee review and regulatory approval.
Cross-state TRM algorithm comparison and gap analysis
Deemed savings development with statistical defensibility
New measure methodology and TRM redline preparation
Equipment performance curve development from manufacturer data
Building electrification and weatherization measure design
Measure tiering and implementation pathway recommendations
We provide engineering peer review of custom project submissions, contractor calculations, and third-party deliverables. Our reviews go beyond checking arithmetic to evaluate whether the underlying methodology, assumptions, and baseline selection are defensible.
Custom project engineering review (IPMVP Options A-D)
Billing regression analysis QC and weather normalization review
Contractor calculation validation against TRM and code requirements
Cost-effectiveness model review (TRC, RIM, Societal Cost Test)
We research building energy codes across vintages and jurisdictions to establish defensible baselines for savings calculations. When programs need to demonstrate that their methods align with current code requirements, we provide the documentation that connects methodology to code references.
ASHRAE 90.1, IECC, and state-specific code analysis
Baseline determination and effective useful life research
Code-to-TRM alignment documentation
Weather data methodology analysis (TMYx, NCEI Normals, NSRDB)

We structure engagements to match the scope and timeline of the work.
Fixed-scope deliverables with defined timelines. Calculator development, measure research, methodology memos. Scoped and quoted upfront.
Ongoing technical support on a monthly basis. Engineering reviews, methodology questions, TRM committee preparation, and ad hoc analysis as needed.
We work as a technical subcontractor to larger consulting firms that need specialized calculator development, measure methodology, or cross-jurisdictional research capabilities.
