What ProStar Energy Solutions does

ProStar Energy Solutions, now operating under the Crete United brand as of February 3, 2025, provides energy efficiency and sustainability advisory services to commercial building owners and operators in the United States. Its core services include energy audits, facility assessments, commissioning and retro-commissioning, energy modeling and utility benchmarking, MEP (Mechanical, Electrical, Plumbing) design and maintenance, renewable energy system design and installation, sustainable building certification support (LEED, WELL, Fitwel), smart building systems and IoT-enabled monitoring, and financial incentive advisory services covering utility rebates, tax incentives, and energy procurement.

The company's technology stack centers on IoT sensor automation for remote energy control, an Advanced Rooftop Controller (ARC) hardware and control strategy for packaged rooftop units that delivers up to 34% energy expense reduction with a two-to-three year simple payback, and the third-party EnergyCAP utility bill management platform for benchmarking and opportunity identification. The underlying architecture is service-delivery-led rather than software-product-led, with advisory outputs feeding design-build installation work delivered through a network of self-performing local companies.

ProStar operates an enterprise field sales go-to-market, engaging directly with facility owners, operators, and managers for strategic capital planning and efficiency projects. Revenue is generated across professional services (advisory, design-build, installation, incentive advisory), subscription/recurring maintenance and predictive maintenance service contracts, and managed services for energy procurement and utility bill pay. Pricing is quote-based and project-specific, with no standardized public tiers. The firm is privately held, headquartered within Crete United's Charlotte, NC network, and serves the U.S. Southeast market with anchor enterprise clients including Busch Gardens Tampa Bay (decade-long preferred energy performance contractor relationship) and unnamed hospitality customers receiving ARC retrofits.
