Stories from the building energy management solution that saves you money.

Inspiration for Building Energy Management and Adaptive and Autonomous Buildings

In 2017, PNNL published a 252-page document for the US Department of Energy to estimate the potential energy savings that could be captured through periodic re-tuning of US commercial building stock.

The document is called “Impacts of Commercial Building Controls on Energy Savings and Peak Load Reduction.

Spoiler: The potential savings is a lot—roughly 5 quads of commercial building energy consumption (about 30%) overall and 10-20% of peak load can be managed or curtailed.

According to EIA 2018 wholesale electricity market prices in the United States, the weighted average cost per MWh was $44.43908. The consumption savings for 5 quadrillion BTUs of energy is equal to 1.465B MWh, or roughly $65B dollars annually.

And, according to EIA’s 2012 CBECS study (commercial buildings energy consumption survey), there are 5.6M commercial buildings, covering 87B square feet of floor space.

It’s worth restating without the math— the United States could save $65B a year in energy costs just through periodic re-tuning of commercial building controls.

That’s over $11.5k per building, or $0.75 per square foot, available for capture every year.

That companies and organizations have since made some of these efficiency measure packages mandates and seen real savings from implementation is a testament to the value of the work.

But how much does it cost to earn those savings?

As illustrated in this excerpted table, one of the practical limitations is that not all energy efficiency measures have the same cost, nor do they have the same payoff.


As a building owner or operator, your basic strategy would be to do the stuff at the top left and avoid the stuff at the bottom right.


But what would happen to this chart if we had a technology that reduced the effort level of every energy efficiency measure and increased their potential savings because it was optimizing continuously 24x7?


As a building owner or operator, your new strategy would be simpler. You’d start with the highest savings opportunities and move down the list.

Thinking in this new paradigm is an instructive framework for developing AI-based building energy management and AI-based automation products.

For example, we can think of EEM23: Advanced RTU (rooftop unit) controls as an outlier unmet opportunity for differentiation. Due to its high effort to implement, this is a service we can assume vendors only offer under strict conditions. It could be that the customer is cost insensitive or weighing other forms of ROI like occupant comfort or operating uptime. It could be that the vendor is selling the capability as part of a package of higher margin services.

The strictness of the condition is Verdigris’ market opportunity.

Here are some other question this study reveals or allows us to infer that I’m eager to explore.
- what combination of geographic focus, building type and asset configurations would most benefit from our product today?
- what product capabilities would result in maximal energy savings? Dollar savings?
- what increase in potential return does real time data, predictive analytics, and artificial intelligence offer for customers?
- which capabilities would lead to collaborative opportunities with the existing marketplace of value added service providers?

Lastly, my goal is to publicly share our roadmap for commercializing Verdigris’ autonomous buildings product—Adaptive Automation.

Why publicly?
- To gather input and feedback
- To connect with like-minded problem solvers
- To maximize value for our customers
- To inspire adoption
- To accelerate the industry segment and further the mission
