What We Bring
Why most buildings stay stuck
Most buildings are still managed reactively — multiple vendors, no unified view, no accountability. That's the gap we fill.
There's a better way to run your building. We built it.
Built Different. Proven Where It Counts.
We think like a software company. We operate like mechanical engineers. That combination is what makes our platform work where others fall short.

Built for the People Who Operate Commercial Buildings
We built MJI Energy around the people who live in buildings all day long — facility managers chasing faults, property managers juggling portfolios, owners watching the bottom line.
Every feature we ship, every integration we build, and every alert we configure is designed for the person who has to make a decision fast.
You need fewer fires to put out
Real-time visibility, predictive fault detection, and remote access — so you're ahead of problems, not reacting to them.
One view across every building in your portfolio
Consolidated visibility across multiple properties, mobile access from anywhere, and clean data that makes ownership conversations easier.
Your automation layer is a financial asset. Treat it like one
Energy compliance benchmarks including NYC Local Law 97, tenant retention, NOI protection, and ESG reporting — all measurable through MJI Energy.
Rooted in New York. Built for the Buildings That Define It.
MJI Energy is actively serving commercial buildings across the New York metro area — and the ambition doesn't stop there. We launched here because this is where the buildings are dense, the energy mandates are real, and the bar for building performance is high.
We're backed by over 30 years of hands-on mechanical expertise from Michael James Industries, one of the region's most trusted commercial HVAC companies. Our software is grounded in real mechanical knowledge. Not just elegant code.
As a Johnson Controls Partner and Niagara-certified firm, we hold enterprise-grade credentials — and as a founder-led company, our leadership is directly invested in every project we take on.
Ready to Build Smarter?
Whether you're upgrading a legacy system, automating a new commercial building, or trying to finally get control of your energy costs — we'll walk through your building and show you exactly what's possible.
No jargon. No pressure. Just a clear picture of where you stand and what better looks like.
