Smart Building Startups Continue to Flourish

— November 17, 2014

Like the “Harvard of the [insert region here],” “the Next Silicon Valley” is a term so trite that it has become meaningless.  You may have heard of the Silicon Hills, the Silicon Strip, Silicon Wadi, or even the Silicon Valley of the East.  It seems that anyone with a pulse is trying to woo tech entrepreneurs into the next Silicon cluster.  Nevertheless, tech activity is not limited to Northern California.  A recent analysis by the Financial Times found that 60% of “unicorns” (tech startups that reach a $1 billion valuation) were created outside of California’s Bay Area.

Indeed, many local governments are trying to establish startup ecosystems to rival Silicon Valley, including the government of Washington, D.C.  Recently, Mayor Vince Gray announced the awarding of grants to tech startups totaling over $800,000.  Several of these companies represent the wave of innovation occurring in smart buildings.  Aquicore, a real-time energy management software for commercial real estate and industrial facilities, received $122,500.  And Azert, the developer of Smart(er) Socket, wall sockets integrated with Apple’s iBeacon technology and Wi-Fi, also received $122,500.

Other People’s Stuff

It might seem strange to think of wall sockets communicating, and even stranger to think of any building infrastructure using an Apple technology.  What’s more, the idea of a software startup that relies entirely on building controls hardware made and installed by other vendors was until recently unthinkable.  In the past, building systems were specifically designed not to work with other vendors’ products in order to ensure a long-term market for replacements and upgrades.  But the convergence of building technology and information technology, the adoption of open protocols, and greater integration between building automation systems have lowered the barriers to entry in the smart building market.

These startups demonstrate that the competitive landscape of smart buildings is changing.  It’s easier than ever to get building data, meaning that a wider pool of competitors are emerging.  What’s striking, and hopefully indicative of future trends, is that these companies are springing up in Washington, D.C., away from the established tech hub of Silicon Valley and away from established global building controls manufacturers.  Future innovation in smart buildings can be driven by anyone, anywhere.

 

Wireless Power Promises New Capabilities for Smart Buildings

— November 11, 2014

Power_Paddle_webIn the science fiction universe, transmitting power over great distances is remarkably easy.  A shield generator could be placed on, say, the forest moon of Endor and beam its power to an orbiting space station.  Lamentably, in the real world, such extensive wireless power transfer remains elusive.  But, 2015 is poised to be a pivotal year in wireless power.

Current wireless power solutions focus on charging mobile phones and electric vehicles, and both are gaining momentum.  On the mobile phone front, the first commercially available products based on the Alliance for Wireless Power’s Rezense standard will soon hit the market, while the Wireless Power Consortium’s competing Qi standard continues to expand around the globe.

In the auto industry, wireless technology represents the future of plug-in electric vehicles and could be a factory option as early as 2017.

Smart Building Applications

The promise of wireless power extends beyond these early adopter markets — particularly in smart buildings.  The proliferation of the Internet of Things in buildings is currently hindered by limitations in power and communication capabilities.  University of Washington professors Joshua Smith and Shyam Gollakota have an innovative approach to tackling both problems wirelessly.  The two have started Jiva Wireless to develop the solution and plan on taking a leave of absence in 2015 to focus on bringing products to market as early as 2016.

Their approach is to harvest ambient energy in the form of Wi-Fi, TV, and cellular transitions.  As detailed in Navigant Research’s report, Energy Harvesting, these types of systems are already gaining traction in a variety of applications.  What’s novel about the Jiva Wireless approach is the use of ambient backscatter communication, which selectively absorbs and reflects radio frequency (RF) signals, effectively combining power and communication into one function.

Landscape Without Wires

The launch of Jiva Wireless adds to an already crowded field of wireless power solutions.  Many of these solutions, as promising as they may be, have yet to make it to the real world.   Funding of these companies does not appear to be a challenge, though.  Energous, a company developing a wireless power solution using radio waves, raised $24 million in an initial public offering in March, despite not having a commercially available product.  Similarly, uBeam, which has a prototype that uses ultrasonic waves to transfer power, just received $10 million in Series A funding, bringing the total amount of capital raised to $12 million.

Wireless power incumbents are shifting, as well.  Duracell, an early adopter of wireless charging for mobile electronics and the pioneer of Powermat technology, is being split from its parent company, Proctor & Gamble, as part of a strategy of divesting non-core businesses.  Meanwhile, JVIS and d-Wired are attempting to resurrect conductive wireless charging by licensing intellectual property from FliCharge.  The shifting landscape of wireless power providers indicates an interesting road ahead in 2015.

 

Healthy Buildings Get a Boost in New Orleans

— November 10, 2014

With the release of LEED V4, the latest version of its green building rating system, the U.S. Green Building Council (USGBC) is addressing two major components of health: indoor air quality (IAQ) and material transparency.

The former is not a new concept in buildings.  According to Navigant Research’s report, Indoor Air Quality Monitoring and Management, global revenue associated with IAQ is expected to grow at a compound annual growth rate (CAGR) of close to 9% between 2013 and 2020.

As for material transparency, addressing the environmental impacts of chemicals and materials in buildings – and their corresponding health effects – could be a game changer.  By partnering with UL Environment, USGBC will make available Environmental Product Declarations (EPDs) for equipment and materials used in buildings, making transparent what chemicals are near and around people in buildings.

And not a moment too soon.  At the Greenbuild conference in New Orleans, Professor Andrew Whelton of Purdue University presented his findings that polyethylene pipes used for water conveyance in green buildings have been leaching chemicals into the drinking water – above minimum standard levels.  Plastic pipes are used in green building construction because they use less embedded energy in their production and transportation, relative to traditional metal piping.  The direct health implications are not clear from Professor Whelton’s findings, but they certainly provide evidence that the chemical makeup and leaching potential are components worth tracking in buildings that are supposedly environmentally friendly.

Better Buildings = Better Business

Another point of the building-health connection was released in a report by the World Green Business Council, a partner organization to USGBC.   The report, Health, Wellbeing and Productivity in Offices, starts with the overarching premise that the most expensive part of any building is its inhabitants, accounting for up to 90% of operating expenses (it’s not clear if this estimate holds true throughout the developing and the developed regions of the world).  The report analyzes the associated health implications of building siting, design, and operations on qualitative and qualitative metrics like occupant health outcomes, well-being, and perceived benefits, as well as organizational and corporate financial outcomes.  For example, an office environment that forces employees to walk around can improve their overall health, reducing absenteeism and physical complaints.  Another example: a 2011 article in the journal Indoor Air indicated that relative to standard temperature baselines in an office, employees were 4% and 6% less productive at cooler and warmer temperatures, respectively.

Greenbuild also hosted Acting U.S. Surgeon General Rear Admiral Boris D. Lushniak. Rear Admiral Lushniak challenged the audience to design preventive healthcare into the built environment, making healthy buildings the default, rather than a specialty.  He also advocated for a “Blue Movement” focusing on human health, like the Green Movement addresses sustainability and environmentalism.  Rear Admiral Lushniak ushered the concept of integrating health into building design, function, and operations for the green building community with passion.

 

Building on Big Data

— November 10, 2014

Advanced methods of interpreting large volumes of data have brought innovations in areas such as healthcare/pharmaceuticals, meteorology, marketing, e-commerce, government services, national security, and financial services.  Despite success in other areas, though, big data is only beginning to have an impact on building automation and energy efficiency.  In a 2013 blog, my colleague Bob Gohn discussed big data in the context of buildings.  In this blog, I’ll take a look at some of the solutions emerging in this area and how the buildings industry will be affected.

Continual Correction

Currently, the most common use for big data in buildings is fault detection and predictive maintenance.  Advances in sensor technology have enabled unprecedented views into the status and functionality of building systems such as heating, ventilation, and air conditioning (HVAC).  Sensors are capable of regularly measuring every aspect of the system’s performance by analyzing the data to identify equipment that needs to be replaced or may be about to fail.  Bringing technicians onsite to service equipment can be a major expense for building owners.  This type of data analytics allows a diagnosis to be made before the technician arrives, while also providing information on replacement parts and other relevant items. Data analytics solutions can also build a list of the known problems in a building and derive each piece of equipment’s usage and cost, enabling a quantitative return on investment (ROI)-based assessment of which upgrade or investment should be implemented first.

As building automation and data analytics continue to advance, new applications within the buildings industry are emerging.  Advanced building energy management systems (BEMSs) harness large quantities of data to provide a visualization of the overall energy consumption of a building or portfolio of buildings.  These systems also have the ability to leverage historical data to provide recommendations for how to best reduce consumption.  Next-generation BEMSs have the capability to adjust building system parameters automatically to maximize occupant comfort and energy efficiency.  One example of this type of advanced system is SHIFT Energy’s Intelligent Live Recommissioning (ILR) solution, which provides ongoing re-adjustments.  Another cutting-edge solution is offered by Ecorithm, whose program also includes richly detailed graphics to visualize processed data across a building’s floor plan, identifying areas of waste and recommending corrections.

Designed with Data

Big data is also playing an increasingly important role in the design of resource efficient buildings.  Building information modeling (BIM) programs allow architects to analyze key performance metrics such as natural ventilation, daylighting, solar heat gain, overall energy usage, and even how people will likely interact with spaces.  These programs utilize vast amounts of data from existing buildings to visualize how a conceptual building may perform.  Such analysis can speed the construction of new buildings by leveraging the data-rich plans from previous projects, modified to fit the specific characteristics of the new site.  This also allows designers to cut costs by eliminating the duplication of work from past projects.  Reducing the time and cost required to construct new buildings is an essential factor in addressing rapidly growing urban populations that lack sustainable buildings and infrastructure.

Despite these achievements, the buildings industry is not yet exploiting available data to the extent that other industries are.  Looking forward, advances in building design, construction, and management can leverage big data and advanced analytics to reduce costs and improve efficiency.  As buildings and cities become increasingly automated and digitalized, data analytics will play a growing role in energy efficient buildings.
