The commercial electricity for HVAC systems accounts for about 50 percent of a building’s total energy consumption. Being one of the major energy costs in a manufacturing facility, it dominates the building’s peak electricity demand. As such, improving the system’s efficiency, in order to cut energy costs, should be every facility manager’s priority.

The energy consumption depends on the climate, comfort preferences, building design, insulation, the timing of use, the size of the HVAC system, heat generated by electrical equipment, and other site-specific factors.

Building owners and businesses can reduce their energy costs by combining several measures that increase an HVAC system’s efficiency while reducing the demand for heating and cooling.

When selecting HVAC systems, pay attention to its design and controls. Components such as motors can impact heavily on the running costs of equipment because some are usually oversized to meet peak demands. An ideal system should have more variable speed control, inverter controls, economizers, demand controlled ventilation, advanced sensors and monitoring, as well as superior diagnostics. In addition, the system should be the appropriate size; not too small or oversized.

By controlling and running the HVAC motors at speeds based on the heating or cooling needs, consumers are able to realize energy savings of between 30 and 50 percent compared to the conventional constant speed operations. Most manufacturers prefer newer algorithm-driven smart microprocessors.

These provide a refined speed control that responds to the changing load in the building. Instead of using on and off cycling, these controls adjust the system according to the actual cooling or heating needs of the facility. More functions can be added through software add-ons as opposed to costly hardware upgrades.

Some of the ways to optimize HVAC systems include the use of thermostats and control systems, locating the HVAC unit in the best place possible, and modifying the ventilation and distribution. These are discussed more fully below:

A HVAC energy audit helps in identifying the operational deficiencies, hence allowing the building manager to take the necessary measures to enhance performance. The audit is often necessary because it helps in determining the amount of energy use, maintenance and upgrade requirements.

Consumers can then reduce their energy costs by optimizing, replacing or retrofitting the HVAC system to become more energy efficient. This not only increases efficiency and reduces the amount of commercial electricity for the HVAC system, but also improves the air quality.

Installing a backup generator can be a great benefit to many situations, but there are still people who think generators are more hassle than they are worth. The truth is there are a lot of myths and untruths out there about how backup generators work and run. Let’s take a few moments to debunk the three most common myths:

Truth: Installing a backup generator is a good idea if you want to ensure you have power during storm season and the cold winter months—times when the power has been known to go out due to high winds, lightening, or icy power lines. These generators can provide power for any family that needs to keep the electricity flowing; whether it’s to keep the food in the freezer from thawing, to keep the family comfortable during extreme temps, or just for convenience.

Truth: While you may remember the loud, noisy, and sometimes even smelly generators from years ago, the modern versions are not nearly as disruptive. If you use a diesel generator, you may still get some of that odor, but when it comes to noise it’s really not that loud. It’s more of a soft whirring sound than it is a loud motor sound. Your neighbors will likely not even know it’s running…that’s how quiet generators are these days.

Truth: If your only frame of reference for a backup generator was from 30 years ago, you may think the power you get will be unreliable. This can still be true for certain generator models, but you can turn to professional electricians to help you find the right generator to meet your needs. If you need the generator to be consistently reliable, you are sure to find a model that will fit the bill. You can also purchase surge protectors to help with this issue and protect more sensitive electronics like computers and important medical equipment.

Don’t let these common myths keep you from experiencing the peace of mind and protection a backup generator can bring to your home. Even when the power goes out, you can continue to use essential electronics in your home and keep your family comfortable when you have the right generator installed.

When your saying goodbye to guests in the evening, you don’t want to send them out in the dark to fumble their way back to their vehicle. Without proper outdoor lighting your front yard can be riddled with hazards at night. Installing outdoor and landscape lighting can add safety in a number of ways as well as add pleasing aesthetics to your home at night.

Outdoor lighting can add functionality in a number of ways – it can illuminate potential tripping hazards, deter criminals, and add a pleasing look to your home at night. The trick is to have the lights positioned correctly to have the desired effects. When placing your outdoor lighting keep these areas in mind:

Installation of outdoor lighting can be different depending on the type of landscape lighting you choose. If you are using solar powered or battery powered you will not require any additional electrical work. If you are looking to install electrical lamps and fixtures on the outside your home or along a pathway it will require the wire to run underground, because of the high voltage, to the home’s electrical system. If you are unsure of how your new outdoor lighting connects to your home, or want to prepare to install new lighting, have an expert electrician do the installation for you.

Three common sources of outdoor lighting are fluorescent lamps, metal halide, and LED lighting. Fluorescent lamps are designed to run efficiently, but can have trouble starting in certain temperatures. Metal halide are highly efficient within a temperature range, but require approximately a minute to warm up – not ideal for motion lights. LED lighting is a popular choice because they are highly efficient, require no warm up time, and the bulb lasts longest, but this all comes at a higher cost.

Outdoor and landscape lighting is very important and something every homeowner should keep in mind. With so many options out there, it can be difficult to know where to start and what will work.
