Pathline Foundry capability statement
Independent energy engineering, analysis & software
Capability Statement · 2026
Pathline Foundry is the energy engineering, analysis, and software practice of RT Williams, PhD, CEM. I help commercial, industrial, institutional, and public-sector facilities meet Building Performance Standards, capture utility incentives, and lower energy costs, and I stay through implementation so the recommendations turn into results.
Core competencies
- Washington & Oregon Building Performance Standards compliance: benchmarking, ASHRAE Level 2 audits, energy management and O&M plans, incentive capture
- ENERGY STAR Portfolio Manager benchmarking and EUI target analysis
- Idaho Power incentive audits: detailed energy assessments and custom efficiency projects
- Energy forecasting and demand-management software
- K-12, campus, and commercial portfolio energy monitoring dashboards
- Ongoing advisory and implementation support
Why Pathline
- Principal-led. The engineer who runs the analysis stays through implementation, not a report-and-disappear handoff.
- Software-enabled. Purpose-built tools (a public compliance checker, monitoring dashboards, forecasting models) keep findings and performance visible after the assessment.
- Independent in the recommendation. No equipment or construction to sell, so what I recommend is what the numbers support.
Past performance
- Washington school districts, with West Ridge Energy (2025 to present): 18 buildings benchmarked across ten districts, ASHRAE Level 2 audits at an 18.5% median recommended savings, and 9 of 10 Tier 1 buildings at or under target with the recommended measures (modeled)
- Idaho custom printing manufacturer (2026): an energy benchmark against 254 peer plants that put demand charges at an estimated 38% to 52% of the bill, and each 10% off the monthly peak at about $2,406 to $4,210 a year, with nothing bought
- DOE Industrial Assessment Center, University of Utah (2019 to 2025): plant energy assessments for regional manufacturers, averaging 13.3% of energy cost in recommended savings at 1.6 to 2.1-year simple paybacks
- FLOCK, smartMFG Solutions (2023 to 2025): a natural gas marketer's penalty cost 33% lower per customer, about $170,000 over the 2024 to 2025 year; about 49% had every recommendation been followed (modeled)
Research: three peer-reviewed papers, three trade-press articles, and talks at DOE, AIChE, and ASHRAE.
