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!

How many light bulbs have you changed in your lifetime? It’s a simple action, and often one that we don’t put much thought into, but what if the simple act of changing a light bulb could make a profound impact on the environment, and the well-being of future generations?  As experienced www.EnergyStar.gov:

“If every American home replaced just one light bulb with a light bulb that’s earned the ENERGY STAR, we would save enough energy to light 3 million homes for a year, save about $600 million in annual energy costs, and prevent 9 billion pounds of greenhouse gas emissions per year, equivalent to those from about 800,000 cars.”

Think about the changes that you can make by simply replacing the outdated incandescent bulbs in your home as they burn out with one of the Alternative Lighting Solutions below. Here are some details on a couple of the most popular Alternative Lighting Solutions available.

Compact Fluorescent Lamp: Modern CFL bulbs for use in homes consist of a curved fluorescent tube and electronic ballast in a single unit, designed as a direct replacement for standard blubs. They use 3-4 times less power than comparable incandescent bulbs. These are great options to replace your standard light bulbs, but they do have a few small drawbacks. According to an article by PopularMechanics.com, while CFL’s do have a much longer lifespan than standard bulbs, they often lose some of their brightness long before their expected lifespan is up, and this is increased in fixtures that don’t allow for efficient cooling of the ballast located in the base of the bulb. Another documented fact about CFL bulbs is that they do contain mercury, which means that they must be disposed of properly by taking them your local approved recycling center. You wouldn’t throw a battery out with the daily trash would you? So you shouldn’t throw these out either.

Light Emitting Diodes: LED’s are a form of “solid state” lighting that have become available recently to homeowners as an incandescent and CFL replacement. Using small light emitting diodes mounted directly to circuit boards, these are highly efficient, and have fewer parts prone to failure, allowing for an expected realistic lifespan of 20,000 to 30,000 hours, when operated at recommended temperatures. While initial costs for these bulbs are higher than incandescent and CFL options, long term energy savings are where this alternative lighting option truly shines, with the average LED bulb using approximately 12-17% of the energy that it takes to run an incandescent bulb of similar output, the end result is a bulb that costs drastically less to power over time.

As a point of comparison, here is a simple chart of the energy usage of LED and CFL bulbs compared to incandescent bulbs, and the output associated with them:

Lighting technology has changed a lot in the past decade, and it is pretty amazing to see what could be on the horizon for future lighting innovations. Take this for example. While most homes will never need this amount of output, it’s pretty impressive to see that something the size of a Christmas tree light, like this plasma bulb, can put out more light, more efficiently, than the giant bulbs that we use in street lamps!

The great thing about these changes is that they aren’t something that requires a huge change in your lifestyle, so they are some of the easiest ways possible to help the environment, and lower electric bills while you are at it!
