What Ekotrope does
Ekotrope is a Boston-based private software company founded in 2010 that builds cloud-based residential energy modeling and HERS rating software for the U.S. new construction market. Its flagship product, Ekotrope RATER, is RESNET-accredited and processes HERS ratings for approximately 1 in 4 new homes built in the United States, making it the most widely adopted HERS rating software in the country. The platform is powered by a proprietary hourly energy simulation algorithm compliant with ANSI/RESNET/ICC Standard 301 and ANSI/ASHRAE Standard 140, and supports multiple certification pathways including ENERGY STAR (3.1, 3.2, MF), DOE Zero Energy Ready Homes, LEED for Homes, and NGBS, as well as state-specific energy codes including a recently approved Florida Energy Code compliance path.
The company's product suite spans the residential energy rating workflow: Ekotrope RATER (energy modeling and rating), Ekotrope CODE (energy code compliance with a Total UA trade-off explorer), Ekotrope ONSITE (mobile field inspection app), and premium add-ons including Scenario Modeling for builder portfolios, Automated Design Assistance for utility programs, QA Track for RESNET quality assurance, and Inspection Sync for field data integration. Revenue is generated primarily through annual software subscriptions (RATER Lite and Standard licenses), product listing fees from building product manufacturers (Broan-NuTone, Daikin, Panasonic, AeroBarrier), premium subscription add-ons (Scenario Modeling, SmartSearch Prospecting, Market Intelligence Dashboard), and API access for third-party project management and CRM integrations. Distribution combines direct enterprise field sales to utilities and large builders, self-serve online purchase for individual raters, and API-based embedding for partner ecosystems.
Ekotrope maintains strategic partnerships with RESNET, ENERGY STAR, the U.S. Department of Energy, Fannie Mae, Freddie Mac, PulteGroup, and major utilities including Mass Save, DTE Energy, Consumers Energy, Eversource, OG&E, and SRP. The company operates across 49 U.S. states and has cumulatively raised approximately $14.96 million across four funding rounds, the most recent being an $11 million SEC-exempt offering filed in October 2025.

Ekotrope competitors and assessment
Company assessmentDirect peers
- REM/Rate (Architectural Energy Corporation): REM/Rate is the most direct competitor to Ekotrope RATER, providing RESNET-accredited HERS rating software with hourly energy simulation, code compliance reporting, and project management features for the same HERS rater, builder, and utility customers.
- EnergyGauge USA (EnergyLogic): EnergyGauge USA is a long-standing RESNET-accredited HERS rating software tool used by residential energy raters for energy modeling, code compliance (IECC), and HERS Index calculation, competing head-to-head with Ekotrope in the rater segment.
Others
- EPA ENERGY STAR Portfolio Manager: EPA's free Portfolio Manager is the federal benchmarking and certification tool for commercial buildings that consumes some energy data adjacent to Ekotrope's residential ratings, but is non-commercial, complementary rather than competitive, and focuses on existing-building benchmarking.
- EnergyCAP: EnergyCAP provides utility bill tracking and energy management software for institutional and enterprise customers, adjacent to Ekotrope's utility program tools but focused on post-occupancy utility bill analytics rather than pre-construction energy modeling and ratings.
- Home Innovation Research Labs (NGBS): Home Innovation Research Labs administers the NGBS green building standard that Ekotrope supports reporting for, serving as a complementary standards-body ecosystem partner rather than a software competitor.
Broad incumbents
- Sefaira (Trimble): Sefaira, now part of Trimble's design portfolio, offers building energy and daylighting performance analysis for architects competing in adjacent energy-modeling territory, but its focus on commercial design rather than residential HERS certification differentiates it from Ekotrope.
- Carrier Hourly Analysis Program (HAP): Carrier's HAP is a commercial HVAC hourly energy modeling tool from a major HVAC OEM, comparable to Ekotrope's hourly simulation engine but oriented toward commercial HVAC sizing and load analysis rather than residential HERS ratings.
- Integrated Environmental Solutions (IES): IES provides the Virtual Environment (IESVE) suite for building performance simulation across residential and commercial buildings; its residential energy modeling capabilities overlap with Ekotrope's hourly simulation approach, though IES serves a broader global commercial audience.
Emerging players
- cove.tool: cove.tool provides cloud-based building energy and daylighting analysis used by architects and developers during early design, overlapping with Ekotrope's design-phase scenario modeling and energy modeling capabilities though focused earlier in the project lifecycle.
- Snugg Pro: Snugg Pro provides home energy audit and retrofit software for residential energy auditors, partially overlapping with Ekotrope's rater workflow tools but focused more on existing-home weatherization than new-construction HERS ratings.
