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.

Christmas is upon us again and more than any other time of year, it’s the time of year where people put strain on their electrical system.  The lights on your house and the beautiful decorations you’ve been storing in your attic finally are brought out and plugged in for your friends and neighbors to view and appreciate.  And, of course, the vast majority of homes you visit have at least one Christmas tree.  Since most of these things are electrical, it’s probably not a surprise to you that, as a top Dallas electrician, I start getting a lot of calls this time of year.  Though it’s always nice to have the business with Christmas so close, I thought it’d be great to share with ways to avoid wiring problems with your Christmas decorations this year:

             In general, there are a few important tips that can help you avoid wiring problems.  If your lights look frayed or dangerous, they should always be replaced or repaired before using them, frayed wiring are hazardous.  You should take care that your electrical source is safe before you even begin the installation process.  To avoid the potential for overloads, you should have dedicated circuits installed for your holiday decorations.

Most importantly, you should never try to supply power for your lights without contacting a top Dallas electrician to help you install the necessary equipment and make the necessary safety precautions.  Short cuts are potentially dangerous. I can remember one example where a customer had supplied power to their lights by splicing an extension cord directly into their circuit breaker box!  Even worse, they’d shut the breaker box door, pinching the cabling!  Left unchecked, even if this hadn’t started a fire, damage from a power surge or overload could have easily destroyed their whole breaker, meaning they’d have to spend thousands to repair the damage at the absolute worst time of year!

38 million people in the U.S. that has migraines or study published in a 2016 issue of Brain shows that green LED lighting reduced pain intensity by 20 percent. In the study, “Migraine photophobia originating in cone-driven retinal pathways,” researchers at the Beth Israel Deaconess Medical Center set out to test whether or not colors can affect photophobia and migraine intensity. Photophobia is sensitivity to light and can be associated with pain and migraine exacerbation. Findings in a previous study fueled the motivation for this study. In the earlier study, the researchers found that blind participants experienced increased migraine pain when exposed to blue light.

Sixty-nine participants with migraines were part of the most recent study. Researchers studied the effects that exposure to white, blue, green, amber, and red low-intensity light had on their pain. Blue and red light were the worst—increasing pain by 18-19 percent. White and amber increased pain by 15 percent. Green was the only color that reduced pain.

Another green-light study found that exposure to low-intensity light from green LEDs reduced chronic pain and migraine severity. In this study, eight participants with fibromyalgia or migraines were given a green LED strip light, and five were given a white strip. Participants were asked to use their strips nightly for one to two hours for 10 weeks. Participants with green LEDs reported a 40-50 percent drop in pain.

The study was so successful for some that they asked to keep their green LED strip lights; they continue to use them in addition to or in place of medicine. In a study was published in a 2017 issue of Pain. The University of Arizona study, “Long-lasting antinociceptive (pain blocking) effects of green light in acute and chronic pain in rats,” found that rats experienced an increased tolerance for thermal and tactile testing methods. These tests measured how long it took for the rats to withdraw their paw when exposed to heat or pricked with a filament. Testing was completed under green or white light. The researchers found that after eight hours of green LED light exposure for five days it took much longer for rats to withdraw their paws. Effects of the green LEDs lasted for four days.

Rajesh Khanna, UA associate professor of pharmacology and senior author of the study, reports that, “While the pain-relieving qualities of green LED are clear, exactly how it works remains a puzzle. Early studies show that green light is increasing the levels of circulating endogenous opioids, which may explain the pain-relieving effects.”  In a UA article, “(Exogenous) Opioids, while having many benefits for managing pain, come with serious side effects.” These medications can also be addictive.

Researchers in this study are not advising people to stop their medications without speaking with a professional. However, it is possible, as in Lesneski’s case, that green LED lighting could eliminate the need for them in the future. “We need safer, effective and affordable approaches, used in conjunction with our current tools, to manage chronic pain,” Ibrahim said.

The second item on this list from Pass & Seymour is this audible GFCI, which can save you from an electric shock. We’ve written about the benefits of GFCI (which stands for ground fault circuit interrupters) before, and you may know that they’re already required in kitchens, bathrooms, garages, and outdoor outlets. What makes this one so unique is that it sounds an audible alarm when tripped.

Say you have a freezer in the garage connected to a GFCI. If that outlet trips, would you know in time to prevent your food from spoiling? Say the outlet trips at your sump pump. Could you reset it before the big rainstorm? With the audible alarm, you’ll be able to reset the switch and not have to worry about any of these problems.

Cost: $20 – $30
