The Coming of Indoor Positioning Systems (IPS)
We’ve all used Google Maps or MapQuest to locate a place, get a map or
directions. The underlying infrastructure is a collection of US
satellites providing a Global Positioning System (GPS). GPS doesn’t
work well indoors though because the signal is blocked. However,
locating assets and people within buildings has value for potentially
improving the performance of buildings, businesses and life safety.
There are “traditional” real time location systems (RTLS) for buildings that use RFID or Wi-Fi but they require a tag or device to be attached to the asset or person. But why use tags and devices when all of us are carrying a smartphone, aka “the new building sensor”. Indoor location technology is already being developed by some of the world’s largest tech companies. It will happen in 2013.
How serious are these efforts? Twenty-two companies formed the
In-Location Alliance six months ago; they include large multi-national
companies such as Nokia, Samsung, Sony and CSR. While a number of
technology approaches have potential for being the basis of indoor
positioning (the identification of unique flickering of individual LED
lights via a smartphone camera, detecting natural electromagnetic
radiation, existing digital TV signals, etc.), it seems the “Bluetooth
Beaconing” approach may be one that initially succeeds, partially
because everyone with a smartphone or laptop has some familiarity with
the technology.
It’s interesting that Google, which is not part of the alliance, launched their Indoor Maps and Indoor Location in late 2011. They already have over 10,000 floor plans for a variety of buildings in North America, Europe and Japan and claim 5-10m accuracy indoors inside buildings.
Being able to identify when and where people are in a building can
improve energy management and life safety, and can generate a treasure
trove of customer and tenant data.
Smart Becomes the New Green
Building owners, designers and facility management personnel are very
focused on energy management and sustainability and many pursue green
building certification. But who wants a dumb green certified building?
Building owners also want smart buildings and believe that smart
buildings already incorporate many green attributes. In addition, smart
buildings really touch on aspects of technology, building systems,
building operations and performance that aren’t addressed in the
alphabet soup of many green certifications (Pop Quiz: How many of us
are familiar with SERF, Earth Advantage, Earthcraft or Class-C green
certifications?).
The lives of typical tenants and building occupants are
technology-laden with constant social and internet connectivity;
they’re expecting advanced technology in buildings and smart building
certification can meet those expectations. We anticipate many
owners will either forgo or complement the green certification and get
their building certified as smart.

Hey, What Are You Looking At? Eye-Tracking
Studying human eye movement has been around for roughly 150 years,
initially performed by simple observation. Eye movement is important
because what people look at and how long they look at it influences
their decision-making and comprehension. Today one of the more popular
approaches to eye-tracking uses video cameras sensing reflected light
from the eye, an approach which is not invasive and generally
inexpensive.
As you may have guessed, today’s eye-tracking is more about commercial
applications. You’ll see eye tracking used in advertising, software
interfaces, retail window design, web pages and almost anything
associated with marketing and selling. Much of the eye-tracking is done
for “prototypes” or “draft” products or ads, gathering data on how a
consumer interacts with “visual stimulus” to perfect the ad or web
page. The basic data evaluates what people look at, and how long
they hold their gaze.
There are eye-tracking applications that can control computers, monitor
automobile drivers or pilots and even usages allowing paralyzed people
to operate wheelchairs via eye movement. And yes, eye-tracking
has applications for building design and operation. One example
is a company that has several “mock supermarkets” or “shopper labs” in
order to track eye movements as people wander down the aisles to
determine what items or displays catch their eye. Eye-tracking can
benefit a building’s interior design, signage, way finding, ergonomics
of manual controls and kiosks. With eye movement directly related to
decision making, we’ll start to see more use of research in the design
and operation of buildings, touching on the “visual” structure of the
facility, its layout, lighting, colors and placement of objects or
controls. The results could be improved productivity in commercial
buildings, wellness in hospitals and enhanced learning in schools.
Community Gardens Are So Yesterday; Community Microgrids Are Now
[an error occurred while processing this directive]
Community gardens have been around for centuries and are found
worldwide. Essentially neighbors share a plot of land to grow fresh
produce and vegetables, and they may trade their harvest with others so
everyone has a little variety. The community garden is environmentally
sound, creates a sense of togetherness, and lowers the cost of fresh
produce. Now substitute the word “energy” for “produce” and you have a
community microgrid.
Just like community gardens, microgrids have to deal with the issues of ownership, management and diversity of energy (or produce). Microgrids have several unique advantages. One is improvement of power reliability; a microgrid with multiple generation sources offers diversity and therefore greater reliability. Second, microgrids have the potential to lower or at least constrain energy costs, for example, using power from the larger grid when prices are cheaper than the microgrid; or conversely, maximizing the use of the microgrid when prices from the larger grid are high. At the very least microgrids offer more flexibility for owners in managing their energy costs. Third is a slight increase in energy efficiency; microgrids eliminate or decrease the transmission and distribution energy losses and also have the capability to recover and use heat locally. The result is higher energy efficiency.
Many neighborhoods and large housing developments already own and
operate their own water systems, and microgrids will be seen as
comparable to a water utility and can offer local control and positive
involvement with energy resources. Expect a microgrid next to the
community garden and well water..
Cross Training for IT and FM
In sports or exercising, cross training means a person trains in a
activity that’s not their main sport or has a variety of exercises to
address different parts of the body. Cross training improves one’s
overall performance. This is a concept that the IT and Facility
Management departments will start to adopt. Each has their focus on IT
or FM but some employees in each will be crossed trained in the other
“sport”.
Typically companies do cross training so that one employee can cover
for another. That’s not the case with IT and FM. It’s about broadening
the skill sets and knowledge of employees to better understand and
appreciate each other’s department roles, concerns and issues. The
upside for employees provided such training is that they gain new
proficiencies and understanding that benefits them personally and
professionally.
IT is being pulled into supporting the building systems managed by FM; it’s not by choice but rather by necessity. In general, IT may know very little about the underlying mechanical and electrical systems in the buildings, unless they’ve had some experience in deploying or managing a data center where cooling and power is critical. If IT approaches the building control systems as simply different types of networks with different protocols, different devices and different functions, cross training may be a little easier. There’s a lesson here for not only IT departments but also IT companies, especially those trying to penetrate the building operation and energy management marketplace; you’ll have little credibility with a facility manager without understanding the building systems and operational challenges.
On the other hand FM is dealing with the building systems penetrated
with some sort of IT infrastructure and often times doesn’t have the
internal resources to address those IT issues. Even if they did have
the capabilities, FM would need to coordinate with IT.
The idea of putting both organizations under an umbrella of “Systems
Engineering” to bridge this gap sounds appealing but it requires much
more effort than simply cross training key personnel; and that’s what
will happen in 2013.
Pilot Projects for Direct Current Infrastructure in Buildings
The argument for DC infrastructure in buildings is quite compelling. Most of the devices and equipment we use operate internally on DC. Some of the renewable energy resources generate DC and also power storage is DC. Plus, eliminating the conversion of AC to DC saves some energy. DC infrastructure or at least a hybrid of both AC and DC infrastructure seems to make some sense.
However,
implementation issues with DC can be daunting: relatively few
people are experienced with the installation of low voltage direct
current; circuit protectors, fuses and insulation materials may need to
be redesigned. Products and devices may need to be modified, training
and test methods need to be developed, and buy-in by architects,
engineers and contractors is critical.
The best way to address these potential issues is through independent
pilots in commercial buildings, most likely involving a hybrid AC/DC
infrastructure with maximum use of DC in building systems, renewable
energy and storage. The objective of the pilot programs would be to
develop real world metrics and identify the work needed for full scale
deployment. Most building owners don’t want to be in the vanguard; they
want some assurance that that the comprehensive approach has been
deployed elsewhere and there are some case studies documenting the
outcomes. Even if the results of the case studies identify some
problems, it’s positive for the DC infrastructure industry as well as
building owners possibly interested in the technology or developments.
The idea of using DC infrastructure in buildings has merit;
implementation issues addressed in credible pilots will move the idea
forward in 2013.
