Building automation is a rising trend in today’s real estate marketplace. The automation of workplace functions allows a Facilities team to increase efficiency and track the use patterns of a space, as well as enables users to schedule events. These “smart building” systems use common communication protocols to talk to each other and share information with a central “brain.” A smart platform also allows integration with other building systems and the company’s IT infrastructure itself. Here, we’ll dive into what building automation really looks like, how it works and how your workplace can apply this technology to its best advantage.


When people talk about a “smart building” what they’re referring to is the autonomous control of a facility—both distributed control and the building’s automation systems. Distributed control systems include things like monitors, mechanical functions, security, fire, lighting, HVAC and ventilation systems, either within a single building or across a campus. Building Automation System (BAS) functions are all about keeping an eye on things—maintaining climate within a specified range, lighting rooms based on occupancy schedules, monitoring performance and device failures and provide malfunction alarms accordingly.

It’s not hard to see how such automation systems reduce building energy and maintenance costs through pre-emptive maintenance and the quick detection of tech issues. In fact, smart energy management practices can often pay for themselves in a short period of time—and help companies tell a powerful sustainability story for customers, partners and employees alike.



According to the Department of Energy, businesses consume 70% of the electricity load in the U.S. and waste 30% of the energy used per year.




By 2020, 19.5% of all buildings in the US will be automated, with 50 million connected devices.




Focusing on HVAC, lighting, and some types of electrical loads, mid-sized buildings implementing a proactive energy management program can expect savings from 10% to 25%.


Here are just a few ways in which automation can help today’s workplaces do what they do…better.


Within a business environment, some controls can and should be in the hands of the people who work there (individual level control), while others automatically kick in based on whether people are actually in the space or not (occupancy level control).

For example, with individual level control, an employee can engage the HVAC system in a conference room using an interface on their IP phone, if they happen to be working after office hours or on a holiday. At the Occupancy Level, unused equipment or appliances will power on and off automatically, without any needed user intervention—like automated blinds that adjust according to heat and light, or lighting that turns on according to movement within a space.

In either case, tracking real-time energy utilization for any building from a central location can help a Facilities team determine energy consumption patterns, design spaces more efficiently, and identify areas of improvement across departments. Better awareness of energy consumption levels and their sources can also enable companies to negotiate power contracts and better verify the billing info provided by those utility companies.

Think of it as air traffic control for a company’s busy meeting areas. Employees can use a scheduling app on their phone to book a room. And even without an app, room sensors tied to the workspace reservation system can note movement and change the occupancy status within the system—effectively reserving the room to prevent employees from double booking. These same sensors can also tie into digital room signage and displays to indicate whether a room is available, reserved or occupied.


Work space is expensive, so employers want to maximize its use wherever they can. In building automation, sensors record the use of a room, eliminating the need for employees to register that information themselves. Then space utilization reports can track when certain environments are being used, to help organizations make decisions about how to best allocate square footage—they can even help inform the creation of smarter workplace design layouts based on usage.


In order for your building automation system to operate, you need five things:




The eyes of the building


Sensors measure information such as CO2 output, temperature, humidity, daylight or room occupancy and come in several types.


These use passive infrared technology to detect heat and movement and are usually mounted to the ceiling or an area where the sensor has full range of vision within the room. Motion sensors deliver a 90-95% accuracy rate—accuracy may be reduced when people sit for long periods of time. While these sensors can detect if a person is utilizing a space, they can’t specify how many.


These sensors utilize the same passive infrared technology as their motion-based partners and are designed to detect the presence of a person in a particular spot—desk, conference table, etc. As with the motion sensors, desk sensors may inaccurately capture data when people sit too long, which is why they tend to be more useful in gathering simple vacancy data.


Unlike the sensors mentioned above, these are ideal for capturing the number of individuals entering and exiting a room. Mounted above the room’s doorways, companies can precisely track occupancy and analyze usage versus capacity. This data also helps improve office design by identifying where people are congregating and by providing data to adjust and improve wasted space.


SMART HUB (Controller):

The boss of the operation


The brains of your BAS (Business Automation System), these digital controllers receive input data, apply logic to that information (think algorithm, like Google does with their search data), then send out a command to other devices to adjust accordingly, based on the info gathered.




The channel your devices talk to each other on


The most commonly used communication channel, ZigBee radio communication protocol, is an openly available global communication standard that addresses the unique needs of low-power, low-cost wireless M2M (Machine-to-Machine) and IoT (Internet of Things) networks. In technical terms, it operates on an IEEE 802.15.4 physical radio specification and even on unlicensed frequency bands including 2.4 GHz, 900 MHz and 868 MHz. Zigbee offers a wireless range of 70m indoors/400m outdoors and uses military-grade AES 128 encryption for an exceptionally high level of information protection.



The IOT that controls your device


Once the controllers have gathered the data and determined what course of action your system should take, those commands are carried out by the system’s output devices. When the controller sends out a command, actuators and relays (the typical output devices) go into action—reducing or increasing the heat in a particular part of the building for example or dimming lights in unused areas.



How you view your data


Simply speaking, these are the screens or interfaces that work as a translator between a BAS system and the humans who operate it. This is where building data is reported (historical, consumable, run times, and system activity information) and can be used as a record of building operations. It also allows immediate diagnosis of a system without needing to be physically in front of the unit.



Intelligent BMS systems integrate disparate BMS devices/networks onto a common network (IP) to enable unified automation and management, even though they may be manufactured by different vendors. In the future, we may even get to a single dashboard that can manage all BMS and Network/IT systems. Running a building should be a data-driven process. Analytics platforms like SkySpark, CopperTree, and others can pull in data from existing equipment and produce useful insights for facility managers to help make better operational decisions. Then the next logical step is to utilize that vast amount of operating data currently sitting unused by existing building control systems and turn it into actionable insights—so building operators can be free to focus on fixing problems, not out there searching to find them.

With today’s automated technologies, businesses are not simply in control of the function, safety and comfort of their buildings, they can operate those systems from a smarter position. One that not only increases employee satisfaction and informs better space allocation, but one that is sure to generate significant energy savings for years to come.


Have you ever Googled “what is charging”? The funny thing is, it seems like such an obvious question until you see the answers.


Your phone battery is essentially a tiny compartment of chemical energy. Every time you plug your phone in to charge, you’re basically the catalyst to reset a chemical reaction which inside the battery. For those of you who passed chemistry, charging is the transfer of electrons from the negative end of a battery to the positive end (and for those who liked chemistry, electrons passing from the negative anode to the cathode).

Most smartphone or smart device technology now includes a Lithium-ion battery. Charging works the same way with these batteries, despite slightly modified components within the battery. But we won’t get into the details.


Amperage is the strength of an electric current often used to measure charging. In fact, amperage is the difference between a lightning quick full charge and an all-day trickle. Amperage is the defining factor of how quickly your device will charge.

Voltage, on the other hand, is the unit of current. Interestingly enough, it is actually a function of pressure – and in this case referencing the chemical reaction that creates charge. In simpler terms (kind of), voltage is equal to the pressure that pushes electrons through their conductive loop (or from the anode to the cathode).

Wattage, on the other hand, is the rate at which energy is either created or spent. Watts represent energy per unit of time. As an example we’ve all run into, when buying light bulbs, a 100W light bulb means that the light bulb will last for 100 Watt hours.

These three concepts tie together in this formula defining charge:

Watts = Amps x Volts

So, for example, a phone charger delivering 5 Watts = 5 Volts x 1000 mA.

According to this in-depth article from Wired:

“For example, consider these charging scenarios for the Retina iPad mini. You could use a Lightning connector plugged into a computer (via USB), an iPhone charger connected to a wall socket, or an iPad charger connected to a wall socket. A PC USB charger delivers 2.5 Watts of power (5 volts at 500 mA). An iPhone charger delivers 5 Watts (5 volts at 1000 mA). A Retina iPad mini charger delivers 10 watts (5.1 volts at 2100 mA).

“While all of these will charge your iPad, using the USB connected to a PC will charge your Retina mini four times slower than if you used the iPad charger it came with. Conversely, if you use a tablet charger for your smartphone, it’d charge up faster than normal (Note: Some devices like the iPhone will only draw up to 1A of current no matter the charger). If you play mix-and-match with these types of chargers like this, don’t worry – you’re not going to blow up your phone or anything crazy like that. And the myth that charging your device at a faster rate will reduce the life of your device’s battery is false. For some older devices, the higher specced charger just won’t work at all, while newer devices will just charge faster.

“Ultimately, it’s really the amperage that determines how fast a charger will supply power to your device. If you want quicker charging, look for a wall or car charger that delivers 2100 mA of current at 5 volts (or whatever voltage the device you’re trying to charge is specced at).”


The age-old question: how fast of a charger is too fast? As you’ve noticed, the larger the brick, the quicker the charge.

Larger bricks accommodate for larger chemical reactions and pressurization – charging phone batteries even quicker. Naturally, an iPad requires more reaction to charge. Accordingly, an iPad charger will charge your iPhone quicker whereas an iPhone charger could equate to a trickle charge for your iPad.

The best way to know that you are protecting your devices and charging properly is to check their tags or manuals. If you don’t have either handy, a quick Google search will keep you on the right track.

But to reiterate the point from Wired’s article, it’s a myth that you will reduce phone battery life or blow up your phone by charging at a higher wattage than its standard charger offers. Newer, higher wattage chargers simply speed up the charging process.
