Mark Kerbel would like the world to think of every building as a giant beehive. In these bustling hubs of activity, each electrical device not only takes care of its individual tasks, but it is also aware of what the other devices are doing. They are part of a team and work together to minimize work and strengthen the “hive.”

Kerbel is co-founder of Toronto-based company REGEN Energy (REGEN). For REGEN, which makes wireless controllers that monitor and manage equipment with high power needs like heating and cooling, or “HVAC” systems, the beehive isn’t simply a sales pitch metaphor. Swarm theory is the company’s foundation.

For the last century, our outdated electric grid has generally worked the same way: energy is generated in a remote location and pushed to homes and businesses, where humans make most of the decisions about what switches are turned on and off. Demand management – like REGEN’s energy load management methodology – brings intelligent decision making into the process, which allows for more efficient use of energy, and helps reduce stress to the electric grid during peak times of energy demand by lessening consumer energy consumption.

“We think the natural world has a lot to teach us about efficiency,” said Kerbel. “And bees and other swarming animals are among nature’s best examples of teamwork and efficiency. Our technology injects swarm theory into a grid that has historically been simple and manual, and makes it intelligent and automatic.”

And much, much more efficient.

REGEN’s Swarm Energy Management technology employs a node at each electrical load in a building. For example, a large corporate campus might install a REGEN node on each HVAC unit. Using REGEN’s patented algorithms (which the company calls “swarm logic”), the nodes communicate with each other wirelessly and are able to balance the attached loads to smooth out the overall demand of a building. In a simple scenario, one HVAC unit might detect that another on a different part of a building will turn off in two minutes, and delay just long enough to avoid adding that extra load. But REGEN’s system can also handle more complex scenarios that consider dozens of nodes that control various types of loads.

All of this, REGEN states, can add up to a peak electrical demand reduction of 30 percent for commercial and industrial properties.

In the energy efficiency industry, things that save small amounts of energy are fairly simple and inexpensive. But improvements that reduce energy use as much as REGEN’s system are often cost prohibitive on the front end. REGEN promises quick energy reduction with a small up-front expense. And, because the parts of the system communicate wirelessly, it doesn’t require advanced metering or utility-side grid investments. It can work today, in many markets.

“The beauty of our system is that it is simultaneously elegant and simple,” Kerbel said. “It is very easy to install — one node per device you want to manage, and they communicate with each other. It doesn’t require any intervention from a customer’s IT department. So it’s easy to get online quickly and manage your loads without a massive retrofit or capital expense.”

In two early deployments in the U.S. — a big box retailer and a movie theatre chain — REGEN’s system resulted in enough energy savings to recoup the system’s cost in one to two years.

As the consumer electronic world evolves, we expect electrical devices to have this kind of awareness and intelligence. But heating and cooling represent such a large proportion of peak demand that it’s a logical, helpful and profitable place to start. And, because the payback period is so short, this is a great investment for schools, large corporate campuses and other multi-building sites that have intensive energy needs.

In our feature on Honest Buildings, we noted that the building sector is responsible for nearly half of CO2 emissions (transportation is a third) and that 75 percent of the electricity produced in the U.S. is used to operate buildings. However, the economics of making buildings more efficient can be tricky. Improvements often require significant capital, and since the tenants – not the building owners – pay the energy bills and reap the savings from efficiency upgrades, building owners often lack the incentive to invest in energy-saving measures.

Enter Managed Energy Services Agreement (MESA), the innovative financing structure from Dallas-based SCIenergy, which provides building owners and managers a way to cut their energy usage without incurring high up-front costs. It does so by allowing an investor to agree to provide energy to a building at a price based on the building’s historical costs. The investor pays for energy efficiency upgrades and then uses the savings to provide a return on their investment.

“We think about intelligence as a source of energy, just like we think of coal, nuclear, oil, and renewables as sources of energy,” said Woolsey McKernon, managing director of SCIenergy. “Building operators are leaving billions of kilowatt-hours, and therefore millions of dollars, on the table because the expense is short-term and the payoff is long-term. We flip that model.”

Tackling the energy challenge from the economic side of things is tough, because in many cases, saving energy dollars long-term requires up-front capital. Services like SCIenergy’s MESA remove that cost barrier and allow customers to reduce their energy use and cost.

Making this approach work requires a unique business model. Customers agree to purchase their electricity and gas from SCIenergy at a monthly cost based on their historical usage. SCIenergy then makes investments in system automation, energy management tools and other building improvements that are expected to save energy. SCIenergy uses the savings to finance their upfront investment at no cost to the property owner. If the savings are less than expected, SCIenergy absorbs the risk.

One SCIenergy customer, Corporate Office Properties Trust, is a real estate investment trust (REIT) that owns more than 20 million square feet of rentable office space, primarily in the Washington, D.C. area. SCIenergy applied its services and made $16 million in improvements to 26 office buildings, resulting in a 25 percent reduction in annual energy costs and more than an 11,000-ton reduction in energy-related CO2 emissions.  In addition, there was an added benefit to tenants as well:  the number of calls to building managers complaining about an office being too hot or too cold dropped 95 percent.

If innovation is where expertise and opportunity intersect, then San Antonio-based Consert Inc.(Consert) is a perfect case study.

Founded in 2008 by veterans of the telecom industry, Consert’s Virtual Peak Plant^TM provides an energy management solution that gives consumers control of the highest energy-consuming electrical devices in their home or business and provides utilities with a low-cost way to tap into an unused energy source during key peak demand periods.

“We find the key is to offer a simple solution to consumers that also benefits utilities,” said Jeff Ebihara, vice president of Consert. “Our goal at Consert has always been to facilitate a mutually beneficial relationship between the consumer and their electric provider.”

The result is cutting-edge technology that connects, monitors and controls high energy-consuming devices including air conditioners, water heaters and pool pumps, which can represent over half of the total load for electric utilities during times of peak demand. The devices in a “Consert-enabled house” are linked using the wireless technology “ZigBee,” creating a Home Area Network (HAN) that can either be controlled remotely or configured to make decisions based on user preferences or outside weather conditions. Utilities may call upon this load during peak hours to reduce stress on the grid, with the consumer never losing comfort or control.

According to Consert, its home automation system can save consumers 15-20 percent on their energy use. When consolidated, these homes add up to a considerable amount of unused energy that utilities do not have to buy, sell or deliver.

The development of a consumer-friendly service that helps save money – and provides some “coolness” while requiring no sacrifice in comfort or convenience – is an important achievement as we look for new ways to reduce energy consumption and increase efficiency. Reducing electricity demand and making more efficient use of electricity is very important both environmentally and for electric grid operators. But beyond the appeal of doing the “right thing,” or the novelty of controlling appliances, there had previously been little to no incentive for consumers to make it a priority. Cutting their energy bill, Ebihara said, has proven a strong incentive.

“Of course there is a small segment of the market that wants to control every last part their energy use,” Ebihara said. “And we are happy to provide that level of control. But we are finding that most people want to “set it and forget it.” They want to save on their energy bill and they might like the convenience of remotely accessing their programs, but they don’t want to have to think about it all the time and they certainly don’t want it to be a hassle.”

Consert’s systems are available through utility companies, most of which offer the equipment free when customers participate in conservation measures. Others sell the equipment at a deeply-subsidized price. In San Antonio, CPS Energy will deploy Consert systems in 140,000 homes at no charge to the customer, reducing peak demand by 250 megawatts.
