Modern buildings, commercial spaces, and even homes increasingly implement advanced building automation and control technology to improve energy efficiency, user comfort, and extend the life cycles of equipment.

At the core of any building automation system, or BAS, remains a central computing hub. This is where software processes the variety of signals it receives from connected sensors, switches, and user inputs. In a typical home, a Wi-Fi network connects devices wirelessly. Further, it will often connect them to the internet, allowing remote access from any web-connected device.

The only real difference between homeowner systems and commercial applications is scale. A large building can have many more devices and sensors connected, but the core function remains the same. The primary focus of commercial systems, however, is energy efficiency over user convenience.

In a large building or factory, even a small percentage of energy savings can have a huge benefit, not only in lower utility costs but also in reductions of CO2 emissions. With an efficient BAS, a building can attain a LEED (Leadership in Energy and Environmental Design) rating, which is a measure of energy efficiency and low environmental impact in building design.

As technology advances, the potential risks grow for building automation. Each day, more devices become connected to the internet. This is now referred to as the “Internet of Things”. The ease and convenience increases, but so does the potential reward for hackers. Anything controlled by the user or by software could potentially be taken over by a malicious hacker.

It is vital that digital security remains a priority, especially in a home setting. Many smart devices are not as secure as they may seem and are often only as secure as the home’s Wi-Fi network. Some good first steps include changing your Wi-Fi network’s password to something unique. Use the latest encryption protocols and enable MAC address filtering, which allows only devices specifically approved to connect to the network.

Building automation systems will continue to grow in ability and convenience. As long as the potential risks are managed, the possibilities for energy efficiency and user comfort remain nearly endless.

Surely you have seen electrical outlets your entire life… but do you know how they work? Their purpose is so important, it can actually save your life. If you read our article last week, you will understand how the electricity has already arrived at the outlet. Grounded electrical outlets then take the energy from your home electrical system and make it available. Here is more about what they are and how they work.

In Canada we have the three-prong outlet that you are familiar with. The outlet’s left hole is smaller and it is the “neutral” slot. The right hole is slightly larger and this is called “hot”. The bottom hole is the “ground”. The electricity flows in a loop, traveling from hot to neutral. This means when you plug your television in the electricity will flow from the hot slot of the outlet, into your television to power it, and then out to the neutral slot.

You have probably noticed that some appliances have only two prong plugs and some have three. This is because some appliances need to be grounded. Electricity always flows towards the ground, and when the electricity flows into your body and into the ground, you experience electrocution. Instead of a body potentially absorbing this current, the grounder redirects the electrical current traveling into the outlet so you will not be hurt. Items that have metal casings, such as televisions and computers, will have their metal cases attached to the grounder so that a current will not accidentally run throughout the case and shock you when you touch it.

When electricity becomes unbalanced in the electrical outlet, the outlet will “trip” and shut off the flow of electricity. For example, if an electronic device comes into contact with water, electricity will escape into the water. Once the outlet detects that less electricity is coming into the neutral slot than what should be, it will shut down. This safeguard protects users from potential harm.

By playing or tampering with an electrical outlet, you can get hurt or severely injured. It is important to use the appropriate equipment and follow manuals before plugging in electrical devices. If you need to make changes to your electrical system you should consult a professional first.
