Founded in 2018, E3 Analytics is a building performance diagnostics company built to fill a critical industry gap: the diagnostic capability missing from energy management. Most organizations have abundant utility data, but it is structurally incompatible, inconsistent, and fragmented, so invisible inefficiencies in usage, power utilization, pricing, and billing inflating their utility costs go undiagnosed and unquantified — sometimes compounding for months or years.
At its core, E3 Analytics exists for one reason: to make diagnosing invisible inefficiencies in building energy and water utilization — and quantifying their financial impact — as routine and inexpensive as a blood test, so that organizations know what to fix and how to prioritize, as inefficiencies emerge.
Drawing on more than 30 years of utility management experience, founder Joseph Zaloom developed a system that transforms complex utility bills into timely performance diagnostics — revealing what is driving changes in utility costs and how much each driver is costing. The system separates invisible inefficiencies from normal usage and price increases, before losses compound.
The resulting intelligence also supports energy compliance reporting, budgeting, procurement, renewable energy decisions, and capital planning.
