Optimum Energy

What Optimum Energy does

Optimum Energy is a Seattle-based, privately held energy optimization software and services company founded in 2004 that delivers HVAC and central plant optimization to enterprise customers across higher education, healthcare, manufacturing, data centers, pharmaceuticals, commercial real estate, district energy, and technology sectors. Its product platform centers on OptiCx, a cloud-based HVAC optimization software powered by OptimumAI machine learning and supported by three patented control engines: OptimumLOOP for water-cooled chilled water plants, OptimumAIR for variable air volume air handlers, and OptimumHEAT for boiler plants, along with OptimumANALYTICS for real-time measurement, verification, and fault detection. The architecture integrates with customers' existing Building Automation Systems and combines continuous optimization, predictive maintenance, and fault detection into a vendor-agnostic stack, backed by 17+ patents including whole-campus multi-chiller coordination methodology.

Optimum generates revenue primarily through two recurring, as-a-service commercial structures: Energy as a Service (EaaS), under which the company funds, implements, and operates energy efficiency upgrades through 10-30 year off-balance-sheet service agreements, and Optimization as a Service (OaaS), a subscription model delivering optimization technology with guaranteed savings. A third managed-services stream covers turn-key project delivery and financing. Go-to-market is exclusively direct enterprise field sales, with regional offices across Seattle, Baton Rouge, Nashville, New York, Minneapolis, Dallas, and San Diego, supplemented by vertical-specific event presence (APPA, ASHE, NACUBO, IDEA, Healthcare Facilities Innovation Conference) and a worldwide exclusivity partnership with Tignis for predictive analytics. The company is owned by private equity firm Bernhard Capital Partners, which installed former Johnson Controls executive Lisa Roy as CEO in 2025, and reports cumulative customer outcomes of approximately 500+ projects, 300+ active sites across four continents, and $298M+ in customer cost savings.

Core offering

Optimum Energy provides proprietary HVAC optimization software (OptiCx, OptimumLOOP, OptimumAIR, OptimumHEAT, OptimumAI) that delivers continuous, real-time, automated optimization of chilled water plants, air handlers, and boiler systems for enterprise facilities. The company delivers its technology via subscription service models including Energy as a Service (EaaS) and Optimization as a Service (OaaS), complemented by engineering services such as retro-commissioning, MEP design, and hydraulic studies.

Product overview

Optimum Energy offers a holistic energy optimization platform combining proprietary software products with engineering services and as-a-service financing models. The core platform is OptiCx®, a cloud-based HVAC optimization platform powered by OptimumAI™ that provides real-time monitoring, fault detection, measurement & verification, and automated continuous optimization. Three patented control software products integrate with OptiCx: OptimumLOOP® (chilled water plant optimization), OptimumAIR® (air handler optimization), and OptimumHEAT® (boiler plant optimization). Supporting analytics are delivered through OptimumANALYTICS™. These software products are available both as standalone solutions and through two financing models: Optimization as a Service™ (OaaS) for subscription-based access with guaranteed savings, and Energy as a Service (EaaS) for long-term partnerships where Optimum Energy may own, operate, and maintain energy infrastructure. Engineering services include retro-commissioning, building controls upgrades, hydraulic studies, MEP engineering, central plant optimization, and building HVAC optimization.
