In other news, scientists at Syracuse University may have created a new light source that doesn’t need electricity or batteries to produce light. How? The firefly. The scientists found a new way to harness this bioluminescence using nanoscience. Mathew Maye, assistant professor of chemistry at SU explained:

“The nanorods are made of the same materials used in computer chips, solar panels and LED lights. It’s conceivable that someday firefly-coated nanorods could be inserted into LED-type lights that you don’t have to plug in.”

Just about everyone is looking for a way to cut down on energy costs and save their business money. Here are some ways to improve the energy efficiency in commercial buildings:

It might seem like common sense, but  most commercial buildings do not need to have their lights and air on at all times. If your building allows, and when it isn’t being used, make sure the energy system is turned off.

As the season changes, so should the temperature of the commercial building. To maintain a comfortable, energy-efficient temperature, set rooms to 75 degrees Fahrenheit in the summer months and 68 degrees Fahrenheit during the winter ones. Adjust rarely used spaces, like bathrooms, to 60 degrees Fahrenheit.

It’s important to remember to change the air filters in a commercial building to save energy. Paying attention to proper filter maintenance will help prevent wasting energy and overworking the equipment.

A room’s temperature, air movement and humidity affect energy efficiency a great deal.   Using fans can help reduce your business’ need to turn up the air conditioner as the fan moves the air around the room.

Not only does turning off the lights in areas that aren’t being used decrease the energy consumption in a building, but replacing incandescent light bulbs with compact fluorescent light globes or even better yet  LED or high efficiency fluorescent lamps can reduce the amount of heat in the room as well as save money.

Occupancy or vacancy sensors can also help reduce the time lights are on.  These sensors adjust accordingly when there is no movement in a room, shutting off the lights.  A full commercial Lighting Control System can keep your business from wasting energy through the monitoring of how light a room actually is and through daylight harvesting.

Being mindful of energy efficiency in commercial businesses means preventing energy waste in any way possible. Investing in energy efficient office electronics and equipment can lessen the amount of heat that’s emitted from these appliances. Turning off the equipment completely can help reduce savings as well.  Also purchasing equipment with features such as “energy saver” can help reduce energy use.

A large amount of heat is lost in the winter and gained in the summer through a building’s windows. In order to reduce this energy inefficiency, a commercial building can double-glaze their windows, or purchase thermal window coverings, if allowed.

As far as a long-term solution is concerned, insulating a commercial building can help lessen the amount of time and energy spent on cooling and heating systems. Insulating ceilings, walls, pipes and roof spaces can be incredibly useful. Energy efficient electricians can help.

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 operating environment, size of the processes, ease of access by operators and maintenance personnel influence the choice of PLC.

A harsh environment with dust or small particles will require a PLC system with an appropriately IP rated enclosure. This prevents ingress of foreign particles into the system. The available space and layout also influence the choice. Therefore, most users require easy access for reprogramming, maintenance, or troubleshooting.

The simplest form of a PLC, all the basic components of a PLC include the I/O points, CPU, and software program. It is typically housed in a single enclosure. These PLCs are attached directly to the equipment being controlled.

Modular PLCs consists of several components on a common bus within a base unit to allow extending of the input and output. These units work on an expandable base unit. Therefore, it provides all the basic components of a PLC, i.e., a power supply, I/O points, memory and the CPU, and slots for additional cards.  These modules, which may be from the same or different manufacturers, are plugged together into a base unit.

This follows the same modular concept, but each of the modules plugs into a rack. The add-on modules are contained in racks which are then linked together through a network of connections. Since the rack mounting PLC is highly scalable, it allows very large systems to be assembled.

In energy management, the PLC monitors and controls equipment such as boiler systems. It helps the organization increase energy efficiency and safety. PLCs are also used in numerous everyday activities. They are found in factories, homes, commercial buildings, airports, unmanned car parks, and more.

Finally, some practical applications include:

Dallas, TX  December 30, 2011– Doug Kerr is the proud owner of a stretch of land located in the rural area of Kaufman County (Texas) where the air is fresh and the hustle and bustle of city life is non-existent. One thing Doug’s land doesn’t have, however, is a city power grid. Traditionally, to gain access to power in an area that hasn’t already been included on the electrical grid, you can pay the local electrical provider a large sum to run new electrical service to your location, or be forced to use noisy, polluting, and high-maintenance fuel-powered generators.
