Our average client stays with us for 10+ years. There’s a reason.
The reason: We’re obsessive.
We hyper-optimize S2, our energy management system, making atomic improvements over time — whether it’s setting up practically redundant valves, or ensuring S2 speaks to the most modern boiler systems on the market.
Why do we spend so much time on these incremental improvements? Because your energy savings compound over time. So 1% here, .8% there, and another 2.2% there: It all has a true impact on your bottom line.
We know that energy savings are crucial to running your real estate right. So it’s crucial to us, too

OUR STORY
Over 3 decades of energy management expertise

Time in history: the early ’90s. The inefficiency of most large-scale heating systems was exposed during the energy crisis of the late 20th century. At the time, our founders managed a large real estate portfolio, and needed a solution to skyrocketing energy costs.
The innovation: Remote boiler monitoring and control.
At the time, it was nothing short of revolutionary. And we’ve been staying revolutionary ever since. Over the past two decades, we’ve built increasingly sophisticated sensors and tapped into burgeoning digital technology with our cloud-based S2 technology.
Today, over 8,000 buildings are outfitted with Entech boiler controls. Entech offers the most precise energy management system available in the world, saving clients hundreds of thousands of dollars a year on energy.
