Building Automation and Control Systems

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. Building Automation Basics 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. In a commercial setting, more advanced industry-standard communication protocols, such

An Explanation of Photovoltaics

Photovoltaics employ solar panels to create energy. Solar power remains a rapidly growing field in the renewable energy sector. It has the potential to completely power our world and drastically reduce greenhouse gas emissions. The Photovoltaic Effect Originally discovered by Alexandre-Edmond Becquerel in 1839, the photovoltaic effect takes advantage of the tendency of certain materials to release electrons when exposed to sunlight. When a positive back plate and negative front conductors are placed on either side of a photoelectric material, free electrons travel from the back plate to the front conductors, hence generating electric current. This current is then captured

The Basics of Programmable Logic Controllers

Programmable logic controllers provide automatic control of processes so that very little human intervention is required. Yet, this results in a well-coordinated, repetitive process. These systems automatically start and shut down critical equipment in large and complex manufacturing processes. When in operation, programmable logic controllers ensure that all conditions are met before starting up a certain machine or process. In addition, the PLC continues monitoring the entire system using a variety of sensors. Consequently, this ensures that everything runs as programmed. The PLC will trip if it detects a malfunction or abnormality in any of the monitored parameters. The system

Electrical Contractor Pre-Fab Strategies for Increased Profitability

A variety of ways exist to quickly and efficiently complete an electrical installation. One method involves using pre-made and pre-fabricated conduits, cables, panels, and devices. Pre-fab strategies cut down on repetitive labor costs and scrap material waste. Furthermore, pre-fabricated components are assembled in quality-controlled factories by highly trained technicians. This ensures that every device and termination is in working order and properly connected. These technicians work faster and cost less per hour than a journeyman electrician, therefore saving the contractor time and money. Custom Bundled Cables When pulling multiple wires into a conduit or tray system, wire organization can quickly

How to Upgrade to a Fluorescent Light Fixture

Tired of dim light in your garage, hallway, office, or kitchen? Follow these steps to easily upgrade a common roof-mounted light fixture to a bright and efficient fluorescent light fixture. Step One: Isolate the Circuit However tempting it may be to simply turn off the light switch while working on the light, always disconnect power at the breaker. Also, if you do not own a voltmeter or multi-meter, you really should. As soon as you open a fixture or junction box, you are taking your own life into your hands. Always assume every wire is live, and double check with

Selecting the Right Wire for Your Electrical Projects

Technically, electrical wire contains a single electrical conductor while cable features a group of conductors protected inside an enclosed jacket. While shopping for electrical supplies for your projects, choose the right wire depending on its application. One type of wire may be suitable to power a new range, while running electricity to your garage requires additional tools and wiring. Knowing a couple of factors helps to figure out the type of electrical wire or cable you need. Safety remains a top priority so buying a better grade of wire or cable seems prudent. Components must safely power up the panel box and
