An app to save energy, one office worker at a time


Turns out helping office workers create personalized comfort zones is also a good way for building owners to save money. A one-year-old California startup called Building Robotics just raised $1.14 million to prove that case, and is aiming to be like a Nest for commercial buildings — minus the smart thermostat.

Using Building Robotics’ app, office workers can exert control over their heating and cooling comfort throughout the day. At the same time, the company’s algorithm, which resides in the computer that controls a building’s heating and cooling system, learns the workers’ temperature preferences and collects data to help building managers reduce wasteful energy use.

A slew of energy management software startups have cropped up in recent years to target the commercial building market. Generally, these companies’ software collects and analyzes a building’s energy use, utility bill, weather data and other information to chart out energy consumption patterns and expenditures over time. More sophisticated software can figure out when to cut back energy use a bit when a utility charges a premium for delivering power (such as on hot summer days). Others can make it possible for building owners to compare the energy use of all of their holdings, or how their energy use compares with nearby buildings with similar attributes.

Often these startups focus only on working with building managers to help them get a closer look at how much electricity various equipment uses and adjusts them accordingly. Building Robotics’ CEO, Andrew Krioukov, said those approaches typically overlook something crucial: that the purpose of the heating and cooling systems, sensors and other technology is to create a comfortable environment for the building occupants.

To achieve that, Building Robotic’s app allows office employees to request temperature adjustments via their mobile phones or computers. They can personalize the comfort levels because many large office buildings today are divided into zones that makes it possible to deliver a certain amount of cold or warm air to each zone. A conference room could be a zone by itself while six to eight cubicles could share a zone.

Those requests from office workers then go to a computer that controls a building’s air conditioning and heating systems. Building Robotics’ software then processes the requests and directs the heating or cooling system to blast air a few degrees lower or higher for, say, 10 minutes. The short-term blast of cold or hot air is usually audible as it gets piped into different rooms. Having that sound provides an assurance to the office workers that they are getting what they asked for.

“We realized, from a psychological point of view, that you want the system to respond to you,” Krioukov said. “We want to make sure they will feel it.”

Office workers can request changes as often as they want. But they will have to make sure their co-workers within the same zone are OK with that. That’s because Building Robotics’ app lets people see their neighbors’ requests.

The startup began running pilot projects at some tech companies in the San Francisco Bay Area earlier this year. Krioukov declined to disclose the names of those companies. Building Robotics also won an opportunity to have its technology evaluated by the General Services Administration, which manages 300 million square feet of federal office buildings. The administration plans to issue a report late next year that gives its assessment of Building Robotics’ technology. From there the federal agency will decide whether to use the startup’s technology.

Krioukov plans to use the $1.14 million seed fund to hire people who expertise in areas such as building management and user experience. The 4-person startup’s investors include Claremont Creek Ventures, Google Ventures, Formation 8, Navitas Capital and Red Swan Ventures.
