This is How We Work

Uncovering hidden CLUES® to cut costs and carbon in three steps.


First, we create vast new building-specific data sets using hundreds of sensors to establish baseline and potential performance.


We shine light on hidden inefficiencies that other technologies can’t detect, then model myriad combinations of possible actions.


Because performance drift is inevitable, our real value is in long-term monitoring for ongoing fault detection and resolution to hit guaranteed savings.

Our proprietary energy optimization technology guarantees real results.

The Carbon Lighthouse Unified Engineering System (CLUES) gives our engineers deep insights into the complexities of your building’s energy use. Others use generic models or rough estimates that can’t capture a building’s unique, ever-changing dynamics. But CLUES crunches real building data with statistical and financial models, enabling us to predict results with incredible accuracy while discovering and delivering maximum savings.

We install 50-300 sensors per building to gather more building-specific data than any other energy service.

To accurately model your building, we analyze an average of 15 distinct types of data.

We model 100s of 1000s equipment + controls scenarios to identify the best ROI solution.

Our guaranteed savings are based on actual data, loads, weather… not rules of thumb.

A duo of service offerings are tailored to meet the needs of all building types.

Our proprietary technology enables our engineers to continuously uncover hidden returns, cut costs and create a new source of revenue for building owners through two service types:

Central Systems

For buildings with central HVAC systems, we use advanced optimization strategies to cut energy use by 20% – 30% and deliver 40% – 60% ROI

Energy Efficiency + Solar

For buildings with available roof space, we combine energy efficiency strategies with solar installations to potentially eliminate utility bills and deliver 30% – 50% ROI

The Carbon Lighthouse Mission

Because stopping climate change will only happen if we can make it easy and profitable, together we are engineering new ways to erase the 20% of global emissions from non-residential buildings.
