  9. Building systems including envelope, mechanical, and ventilation — assess together to prioritize weatherization work orders on assigned residential projects.
  10. Time management practices — apply to complete multiple weatherization installations within scheduled crew workdays across a residential program territory.
Proficient
Senior / Expert IC
  1. Comprehensive building inspections — conduct autonomously to identify all required weatherization measures including repairs, modifications, and equipment replacement.
  2. Blower door and diagnostic pressure testing — perform and interpret results independently to develop targeted air sealing strategies for complex residential buildings.
  3. Combustion safety testing — diagnose appliance failures and recommend corrective actions to homeowners and program managers based on test findings.
  4. HVAC air flow and furnace efficiency diagnostics — troubleshoot non-routine system performance issues using advanced analytical equipment on residential and light commercial sites.
  5. Full insulation scopes including attic, crawl space, basement, and wall assemblies — install and quality-check against program performance standards without supervisory review.
  6. Weatherization techniques and energy regulations — explain and recommend to clients in alignment with federal, state, and local program codes and statutes.
  7. Quality control analysis — conduct on completed weatherization installations to verify air sealing and insulation work meets program and building science standards.
  8. Project management software and CRM tools — use to track job status, client records, and program compliance documentation across an active caseload.
  9. Complex air duct sealing and ventilation system modifications — design and install to resolve moisture, combustion, and efficiency problems in older residential stock.
  10. Systems evaluation methods — apply to assess whole-house energy performance and validate that weatherization measures achieved intended efficiency outcomes.
Advanced
Lead / Principal / Executive
  1. Weatherization program quality standards — establish and enforce across field crews to ensure consistent compliance with energy codes, safety regulations, and funding requirements.
  2. Field technician training programs — design and deliver to build crew competency in diagnostic testing, insulation installation, and combustion safety procedures.
  3. Building science and energy performance systems — evaluate at portfolio scale to identify recurring deficiencies and recommend program-wide process improvements.
  4. Energy audit and inspection protocols — develop and update to reflect changes in federal and state weatherization statutes, building codes, and best practices.
  5. Client and community outreach strategies — lead to educate homeowners and local agencies about weatherization benefits, eligibility, and energy efficiency options.
  6. Multi-site project planning and scheduling — direct to optimize crew deployment, material procurement, and job completion timelines across large residential weatherization programs.
  7. Data reporting and program performance metrics — oversee using analytical and project management software to meet funder reporting requirements and demonstrate program impact.
  8. Contractor and subcontractor relationships — manage to ensure quality, safety, and cost-effectiveness of weatherization work delivered under program contracts.
  9. Cross-agency coordination with utilities, housing authorities, and health and safety organizations — lead to align weatherization services with broader community energy and housing goals.
  10. Emerging weatherization technologies and materials — evaluate and pilot to advance organizational capacity and prepare crews for adoption of next-generation installation methods.
