What ConSol does
ConSol is a Sacramento, California-based building energy advisory firm that has operated continuously since 1983, providing technical consulting, energy code advisory, building energy modeling, quality assurance inspections, and market transformation program design to building and utility industry clients across the United States. The firm's core service portfolio spans six offerings: Building Energy Modeling, Energy Code advisory, Industry Seminars, Market Transformation Programs, Quality Assurance and Inspections, and Technology and Market Analysis. Methodologically, ConSol applies established engineering tools (CBECC, Energy Pro, BEopt) to predict building energy efficiency, usage, and emissions, then advises clients on cost-effective pathways to meet federal, state, and local codes. Since 1990 the firm has performed more than 814,000 quality assurance field inspections and 110,000+ home energy audits, including 6,500–9,000 inspections annually for the California Department of Community Services and Development weatherization programs and a 1,000+ audits-per-month throughput under the City of Fresno's Central Valley Energy Tune-up program.
The firm's customer base is concentrated vertically across the building and utility ecosystem: production homebuilders (Lennar, D.R. Horton), building product manufacturers (Rheem, A.O. Smith, Owens Corning, SunPower, Boral Roofing), utilities and CCAs (Southern California Edison), federal/state/local government agencies (California Energy Commission, City of Fresno, CSD), trade associations (CBIA, Leading Builders of America, Western Propane Gas Association), and developers (Tejon Ranch, USA Properties Fund, Newhall Land Company). The go-to-market is enterprise field sales driven by long-cycle regulatory engagement: ConSol is an independent moderator in the triennial California Energy Code development process and participates in California Energy Commission rulemaking workshops.
The business model is professional services with a training product extension. Advisory revenue is generated through project-based consulting engagements, multi-year program management contracts (30+ years of state, federal, and private contract experience cited), and field inspection work priced on a per-inspection/engagement basis. The training and certification arm is delivered through ConSol's sub-brand and partnership with CHEERS—an EPA 608 approved provider and CEC-regulated Energy Code Compliance Provider—via an online learning platform (TalentLMS) selling EPA 608 Type I/II/III/Universal certifications, A2L & A3 Low-GWP Refrigerant Training, ECC Rater certifications, and advanced certifications (ENERGY STAR, DOE Zero Energy Ready Home, EPA WaterSense). Pricing is published on the website on a per-course/per-certification basis ($95–$750 per elective course), with volume-based group pricing for trade schools, community colleges, utilities, and associations. The firm is privately held with no disclosed external funding, ownership structure, or M&A activity, suggesting a bootstrapped, founder/employee-owned advisory model.
