The firm provides energy efficiency engineering, building certification support, decarbonization planning, ESG consulting, and portfolio-level sustainability management for existing buildings, new construction, and adaptive reuse projects across all 50 states. Its primary customer segments are commercial and multifamily building owners and property managers, lenders and financial institutions performing energy and climate risk due diligence, affordable housing developers requiring green certifications for LIHTC and government financing, and institutional real estate investors with GRESB and ESG reporting obligations.
The company's service portfolio spans energy audits, benchmarking, energy modeling, commissioning and retro-commissioning, EV charging consulting, greenhouse gas inventories, HERS verification, climate hazard and property resilience assessments, and full-service support for LEED, ENERGY STAR, BREEAM, Green Globes, GreenPoint Rated, Enterprise Green Communities, Fitwel, NGBS, and WELL certifications. Its proprietary SaaS platform, SiteLynx, provides centralized utility and ESG data tracking, carbon emissions monitoring, energy compliance screening, and benchmarking across building portfolios; the platform was featured in a Lawrence Berkeley National Laboratory report on decarbonization software in 2025. In 2024 Partner Energy introduced Portfolio Advisory Sustainability Solutions (PASS), an integrated advisory model that combines strategy, engineering, and data management across the asset lifecycle.
Revenue is generated through project-based professional services engagements on a quote-driven, multi-year contract basis; the firm executes hundreds of projects annually and reports certifications across 192 properties in 2024 (up from 161 in 2022). Go-to-market is sales-led and direct, supported by thought-leadership publishing in industry outlets such as GlobeSt.com and GRESB Insights, conference presence at MBA CREF, NAREIM, CREFC, and IMN ESG Forums, and an active webinar and content program. The firm is privately held as a subsidiary of Partner Engineering and Science, Inc., with no public revenue disclosure and no outside funding rounds on record.
