During a cab ride in San Francisco an (energy-efficient) light bulb went on in the mind of Johnson Controls’ Kevin Self.
Out of the blue, Self’s cabdriver said he recently purchased a smart thermostat for his apartment. He liked being able to control his air-conditioning remotely, using an app on his cell phone. More importantly, the driver enjoyed paying less for his monthly utilities.
The conversation illuminated a bright future for the Michigan alum, who holds undergraduate and graduate degrees in engineering and bioengineering, respectively. As VP of strategy and corporate development at Johnson Controls’ building efficiency business, Self oversees a $14.6-billion operation. And he is on a mission to make “smart buildings” the norm and not the exception.
“Here’s a cabdriver making this decision regarding his small apartment,” he says. “So why are we not doing it for the millions of square feet of buildings that exist on this planet?”
Those buildings consume about 40 percent of all the energy we produce here on Earth, Self says. And that is a scenario that requires a dramatic shift in perspective — from the supply side of the energy equation to demand. The most sustainable strategy is not to produce increasing amounts of new energy, but to effectively monitor and manage the supply that already exists, he says. It’s about optimizing usage, reducing emissions, and avoiding energy costs. That’s where the smart technology comes in.
“The cheapest next power plant to develop is the one you don’t have to develop,” says Self, “because you’ve succeeded in reducing demand.”
Self sees an energy-efficient sweet-spot on the horizon. He cites the convergence of a few significant trends in technology and consumer behavior: Today’s tech-savvy millennials have grown up using handheld computers. An increasing number of today’s most popular consumer products (from pedometers to major appliances) use smart technology. And consumers buying those products are well-versed in the ways of apps and analytics.
The key is to think about that building (and the buildings that surround it) as living, interconnected organisms with unique lifecycles and sets of operational needs, Self says.
Old buildings, new tricks
Milwaukee-based Johnson Controls Inc. recently retrofitted New York’s iconic Empire State Building. In just three years, the 80-year-old building has cut $7.5 million in energy costs. The savings exceed the firm’s initial projections, according to a report posted on the Johnson Controls website.
The Hawaii project addresses interconnected systems of heating, cooling, lighting, ventilation, and more. It will serve as a model for other multi-building initiatives, Self says.
“You might start by looking at a chiller in the basement; then you’re looking at the whole building, the whole block, the whole city.”
Johnson Controls also is working with the University of Akron to cut the energy consumed across its campus and reinvest those savings into university upgrades. Overall, the 15-year contract is projected to result in more than $58 million through streamlined operational and energy savings.
A change is gonna come
The ability to monitor and adjust real-time energy usage creates one stream of cost-savings. Preventative maintenance is another, Self says. In a world of extreme weather and extended power outages, it is essential to increase the number of resilient buildings capable of operating with fewer, better-managed resources.
If contingency planning doesn’t resonate with energy users, perhaps competition will. Utility companies often supply customers with data comparing their energy usage to neighbors. Competition can be a strong motivating factor – at both the consumer and commercial level – in upping efficiency and seeking cost savings.
“Maybe in the past people were motivated to [opt for sustainable solutions] because it was ‘doing good,’” Self says. “But most people are driven by dollars and cents. The goal is to demonstrate that making this change could be good for your pocketbook.
“In the end, it’s about reducing the energy demand necessary to sustain the planet going forward, which is a good thing for all of us.”
Self serves on the external advisory board of the U-M Energy Institute. He also serves on the board of directors for the bipartisan Alliance to Save Energy, a group designed to raise awareness at the municipal level. The alliance is spearheading the Energy 2030 campaign, with the intent to double energy productivity in the U.S. by 2030 and save $330 billion annually in avoided energy costs.
