Connects With

Works with your existing stack

Connects with utility meters, energy data hubs, and existing EMS platforms via APIs.
Setup complexity: Easy
Ento is an AI-powered energy management system for energy and sustainability professionals. It connects to your existing utility meters to automatically identify, prioritize, and verify energy savings opportunities across large building portfolios. The platform helps you reduce consumption, prove savings with IPMVP-aligned M&V, and build a data-driven investment roadmap.
Comparison

How it compares

Ento vs. Traditional Building Management Systems (BMS): Choose Ento when your priority is rapid, portfolio-wide opportunity analysis without hardware changes. It's an intelligence layer that tells you *where* to look. Opt for a traditional BMS when you need granular, real-time control and automation of specific building systems (like HVAC) within a single, complex facility. Ento finds the problem across 100 buildings; a BMS solves the problem within one. Many organizations use Ento to direct the efforts of their on-site BMS teams.

You need direct, automated control over HVAC and lighting systems, not just analytics.
Your focus is on a single, complex building rather than a large portfolio of simpler ones.
You require deep sub-metering and sensor-level data for diagnostics.
The decision

Is it worth it?

Return on investment
With pricing on request and a vendor-claimed payback period of three to six months, a single AI-identified fix can often cover the annual subscription cost.
Built for
Energy managers, sustainability consultants, portfolio managers, and facilities directors in public, retail, and commercial real estate sectors.
Effort to adopt
Easy
Compliance
The platform's Measurement & Verification (M&V) process is aligned with the International Performance Measurement and Verification Protocol (IPMVP) and provides automated support for ISO 50001 certification. Other compliance postures are not publicly documented — verify with vendor.

Best for energy professionals managing large, multi-site building portfolios who need to automate waste detection and verify savings at scale.
In-Depth Overview
Ento replaces slow, manual energy management with an automated, scalable platform. Where traditional approaches require months of custom data pipeline setup, Ento connects to your existing utility meters and delivers insights in days, with no new hardware. Instead of energy managers spending hours in spreadsheets trying to find problems, Ento's AI automatically surfaces the 10% of sites driving 80% of waste, ranking opportunities by savings potential. This allows teams to focus on high-impact actions. Crucially, Ento automates savings verification. It replaces manual calculations and expensive audits with real-time, weather-normalized, IPMVP-style Measurement and Verification (M&V) that stakeholders trust. For strategic planning, it moves beyond static consulting reports to a continuously updated, data-driven investment roadmap. Proof of its effectiveness is seen in its application across over 55,000 sites and case studies with major clients like Salling Group, who used the platform to achieve savings of several million Euro.

The main trade-off is its reliance on main meter data, which may lack the granular, sub-system diagnostics of a sensor-heavy BMS solution without further on-site investigation.

Questions & Answers

Frequently asked questions

What's the best AI tool for managing energy consumption across a large property portfolio?

+
Ento is designed specifically for this purpose. It is built for organizations managing anywhere from 50 to over 1,000 buildings, automatically benchmarking sites and surfacing top priorities across the entire portfolio from a single dashboard.

How can I automate energy savings verification for my buildings?

+
Ento uses the International Performance Measurement and Verification Protocol (IPMVP). It builds a counterfactual model of consumption and compares actual post-project usage against this baseline, providing verified savings reports in kWh, CO₂, and cost.

Is there an energy management system that doesn't require hardware installation?

+
Yes, Ento requires no new hardware or sensors to get started. It connects directly to your existing utility meter data through APIs and data hubs, allowing for full portfolio visibility from day one.

We already have an EMS — why would we add Ento?

+
Ento acts as an intelligence layer that makes your current EMS investment work harder. While traditional EMS platforms collect data, Ento turns that data into prioritized, actionable insights, tells you where to focus, and automatically verifies the savings.

How to find the biggest energy waste opportunities in a portfolio of 100+ buildings?

+
Ento's platform automates this process. Its algorithms analyze consumption data across all sites, normalize for variables like weather, and pinpoint the top 10% of sites that typically drive 80% of energy waste, allowing you to focus your efforts efficiently.

What is the ROI on AI energy management software like Ento?

+
Most Ento customers see a payback within three to six months. The platform is designed to identify high-impact savings so quickly that a single fix often covers the annual subscription cost.
