Thermostat Program Lets Consumers Choose Renewable Energy

— May 17, 2016

Home Thermostat DialEnvironmentally conscious consumers have a new friend in Canadian thermostat and energy management solutions provider Energate and partner WattTime, which is piloting a new program in the Chicago area. Participants in the program receive one of Energate’s HōlHōm smart thermostats with a new Clean Power Mode feature, which prioritizes the use of clean energy sources over traditional fossil fuel resources. The technology works by identifying the availability of clean energy sources through public and private data sources and synchronizing the HVAC system’s air conditioning and heating cycles to correspond to this availability. It follows the common set-and-forget trend with smart thermostats, where the activation of Clean Power Mode will automatically prioritize clean energy resources without intervention by consumers. Energate also claims that this technology will never raise a consumer’s monthly energy bill or make them sacrifice comfort. The pilot program is funded by a $600,000 grant from The Great Lakes Protection Fund and is set to begin this month.

The underlying technology in these smart thermostats was developed by WattTime, a non-profit company built on research from the University of California Berkeley, Yale, and Carnegie Melon that provides environmental demand response software. WattTime’s research has been funded by companies such as Fast Forward, Great Lakes Protection Fund,, and the Berkeley Energy & Climate Institute. The goal of the company’s technology is to give consumers the choice of whether or not they want their energy use to support fossil fuel power plants or clean electricity. Though WattTime’s work with Energate is only in the pilot phase, the company hopes to implement the program on a larger scale and partner with utilities to offer incentives for using this technology.

Various Partnerships

While Energate only recently became partners with WattTime, the non-profit has already been working with other companies to deploy its technology. Building Clouds, a building energy management systems (BEMS) solutions provider, partnered with WattTime to deploy equipment on an existing HVAC unit on the University of California Berkeley campus that allows WattTime’s software to activate the HVAC system at times when clean energy is available. The company has also partnered with electric vehicle (EV) charging station provider eMotorWerks to launch a smart EV charging station called JuiceBox Green 40, which uses timing algorithms to identify which power plants will provide electricity for EV charging and shifts the time of charging to minimize carbon emissions. This allows consumers to minimize the pollution footprint of their EV at current reduction rates of up to 60%. As seen in the graphic below, these partnerships address buildings, homes, and EVs, each of which are not only heavy electricity users, but also significant contributors to carbon emissions.

Though these are relatively small projects, they demonstrate a simple (and potentially scalable) way to integrate renewables further into the energy mix, supplement existing demand with renewables, and reduce carbon emissions. WattTime’s software can make renewables more reliable, an issue that has consistently presented major challenges to the mass adoption and investment in clean energies given their intermittent power generation. It can also help reduce the portion of renewables that go unused, as high electricity output from renewables does not always correspond to peak demand, which has driven the need for large and expensive energy storage projects to store excess energy for times when the sun is not shining and the wind is now blowing. Additionally, this technology represents a larger trend in the industry of organizations moving to more customer-centric business models and giving consumers more choice when it comes to their energy consumption.


Smart Home Products Resonate with Consumers, and Utilities Should Take Note

— May 9, 2016

AnalyticsAmerican consumers are ready for the next wave of connected products—or the Internet of Things (IoT)—for their homes. Their awareness is growing about how these products can bring benefits to their lives, according to research sponsored by Alphabet subsidiary Nest Labs. While this is encouraging news for hardware vendors and utilities aiming to capture the energy management component, the road ahead has some bumps (more on that in a moment).

First, the results from the two Nest-sponsored studies provide a positive outlook: 81% of respondents either own or are interested in buying a connected home product in the next year. They see the major benefits as increased convenience (54%), increased security (44%), reduced energy bills (38%), and boosted home values (21%). Enthusiasm for these products is on the rise as well, with 38% of respondents more interested today than they were 6 months ago. Asked which brands come to mind in the connected or smart home space, the respondents ranked them in this order: Nest (21%), Apple (12%), and Samsung (8%).

Increasing Awareness

The growing awareness is being felt and fueled at the retail level and among broadband service providers as well. Connected home products are among the fastest growing categories in the retail environment, according to one Home Depot executive. Sears recently introduced the first of a growing assortment of smart home products to be marketed under its Kenmore, Craftsman, and DieHard brands; each of these five first products is Wi-Fi-enabled.

Likewise, a new partnership between Comcast and Earth Networks’ WeatherBug Home highlights the growth in smart home technology and an increasing focus on energy efficiency. “The smart home is quickly becoming a reality, and when it comes to energy efficiency, knowledge is power,” says Bob Marshall, CEO of Earth Networks. “We are excited to partner with Comcast to extend the benefits of our unique home energy insights to Xfinity Home customers and the utilities that provide their energy services.”

Addressing Glitches

But looking beyond the smart-IoT-home hype, there is some reality to consider. Samsung has had to contend with some glitches with its SmartThings technology for the home. Nest has also been called out for problems with its thermostat. Consumers have issues, too. The vast majority (82%) are concerned about keeping personal information secure online, and nearly half (43%) worry that new home technologies will quickly become outdated, according to Nest-sponsored research.

For utilities and other smart home market stakeholders targeting energy efficiency products, the overall upward trend is still encouraging. In my research, I’ve found the market for these products to be growing, and they will likely go mainstream in coming years. Nonetheless, shrewd players will develop a strategy for getting beyond those pesky speedbumps.


What Makes a Smart Thermostat Smart?

— April 1, 2016

Home Thermostat DialThere’s no clear definition of a smart thermostat. In fact, as more offerings have entered the market, the definition of a smart thermostat has become more unclear. Some consider a thermostat “smart” if it has two-way communications (i.e., you can view and change settings via a smartphone). However, according to Navigant Research, this type of thermostat is actually considered a communicating thermostat. A communicating thermostat is a device solely enabled to gather and transmit in-home temperature data in a two-way format that can be accessed and adjusted remotely via a web portal or mobile application. A handful of communicating thermostats on the market today have actually been labeled or marketed as smart thermostats despite their lack of smart features. So what is it that makes a smart thermostat smart?

The answer is algorithms. The algorithms hidden in the backend software of a device are what enable it to perform a variety of different functions that make it advanced, not just communicating. For thermostats specifically, algorithms tend to enable functionalities that can optimize heating, ventilation, and air conditioning (HVAC) settings for consumers.

Algorithms for All Occasions

There are algorithms for a variety of different thermostat functionalities. The Nest Learning Thermostat’s learning algorithm is what enables it to adapt to a user’s lifestyle and the changing seasons to optimize the user’s HVAC settings and minimize energy consumption without affecting comfort. EcoFactor uses a series of advanced algorithms alongside real-time data from communicating thermostats, weather conditions, and customer preferences to make automatic micro adjustments in temperature to save customers money and energy. The ecobee3 is advertised as smarter due to its support of algorithms for capabilities ranging from alerts and reminders to optimal humidity control to home/away sensing.

Algorithms are still improving and are increasingly supporting different features. Manufacturers of thermostats have teams dedicated to developing new algorithms and adjusting existing ones to best serve their customers. Similar to updates in apps like Instagram, these algorithms can be added or modified on devices already in use. What developers can do with algorithms and the value they add to thermostats make these devices unique and desirable to consumers. Without its learning algorithms, the Nest thermostat would only be a well-designed on/off switch controllable through a smart phone instead of the learning thermostat that has driven the market and become one of the most popular smart devices available today.

Smart or Communicating?

The value that algorithms add contributes to the importance of differentiating smart thermostats from communicating thermostats. The difference between the two is commonly misunderstood. In fact, the Environmental Protection Agency has not created a definition of “smart” as it applies to smart devices (including smart thermostats), and there is no regulation over the use of the term. This can have negative implications on the market, from frustrated consumers to inaccurate quantification of devices. For simplicity’s sake, Navigant Research categorizes smart thermostats as those with the same functionality as a communicating thermostat (i.e., two-way communication), but which are enhanced by data gathering and analytics that optimize HVAC settings for efficient and automated energy consumption.

Where greater specificity is warranted, Navigant Consulting has defined a smart thermostat as having at least three of the following features (enabled by algorithms): occupancy detection, heat pump lockout temperature control, upstaging and downstaging optimization, optimal humidity control/AC overcooling, fan dissipation, behavioral features, and free cooling/economizer capabilities. To learn more about smart thermostats and how they are different from other thermostats, look for the upcoming update to Navigant Research’s Smart Thermostats report.


Lone Smart Devices Less Effective than Those Paired with Programs and Services

— March 17, 2016

Home Thermostat DialThere is a wide variety of options on the market for consumers interested in better managing their energy consumption, becoming more environmentally friendly, and generating their own energy. Enabling technologies such as smart thermostats can help customers achieve these goals. They can also be a point of contact for utilities that want to increase customer engagement and improve customer satisfaction, a concept that is covered in Navigant Research’s recent Residential Customer Engagement research brief.

However, the problem with the way these technologies exist today is their lack of integration with other enabling technologies, demand-side management programs, and other energy services. In essence, enabling technologies themselves may not be as useful to consumers as one might think.

In fact, smart thermostats on their own may actually result in increased energy consumption, despite the popular belief that owning these devices will reduce a consumer’s energy use and energy bills. This increase in consumption can occur because of the remote control capabilities of smart thermostats, which allow consumers to adjust their thermostats preemptively (or before arriving at home), whereas traditional programmable thermostats can only be adjusted once a user is home. Because of this, on December 31, 2009, ENERGY STAR required that manufacturers cease the use of the ENERGY STAR label for thermostats, asserting that although thermostats do have the potential to save energy, it is not the thermostat itself so much that saves energy, but the behavior of the consumer and the thermostat’s connection or integration with other devices and systems.

This lack of integration between energy services and enabling technologies not only causes problems for consumers, but also vendors and companies. In a survey of 423 web and mobile application stakeholders, 74% reported that the lack of integration in existing tools affects their ability to use data effectively. Essentially, the existing technologies that we have today are not integrated, which leads to the data becoming siloed. This makes devices and enabling technologies themselves less valuable and less effective to the consumer.

Startup Solutions

However, several vendors in this space are offering integrated enabling technologies and energy services. Quby, a startup company founded in 2004 and acquired by the Dutch Utility Eneco, offers a white-label smart thermostat and energy display device where consumers can subscribe to energy services, such as monitoring power generated by rooftop solar panels and tracking home energy consumption. The company has seen success with utilities in Europe and plans to spread to the United States later this year. Salus, a subsidiary of Computime, manufactures devices, sensors, and control switches and offers an integrated energy management solution that utilizes combinations of its manufactured hardware devices with software to form a complete platform.

The growth in enabling technologies is allowing consumers to participate in energy activities that were not possible or accessible before, and they are enabling additional points of contact between utilities and their consumers. However, it is important to keep in mind that these technologies are much more useful to consumers, vendors, and utilities when integrated with programs, energy services, and other enabling technologies. The integration of these devices is the key to saving energy and reducing consumption, not necessarily the device itself.
