The DC area is likely to see more rain over the next few months as fall weather arrives. Among the many issues that homeowners could face if the rain is particularly torrential is flooding. This opens families up to a number of safety hazards, not least of which has to do with the exposure of electrical systems to moisture. As one of the leading has a rundown of four rules for dealing with electrical issues after a flood which can give you a basic understanding of what you should do:

Antique architecture might be beautiful, but the electrical wiring in old houses doesn’t carry the same kind of charm. If you have an older home with an electrical system that hasn’t seen updates in a long time, you could be living in dangerous conditions without realizing it.

There are warning signs that may indicate your wiring is too old, but if you’re ever in doubt, there’s a fool-proof way to get an assessment of your system: Call in a professional! An expert will perform an in-depth inspection of your home’s wiring so you can be aware of the situation and the solutions for it.

With outdated wiring, you may notice strange signs from time to time. Some of them might occur with more regularity than others, but any instances at all can be cause for concern. In general, you’re at risk for having old wiring if your house is 40 years old or more. A few warning signs include:

Although old wiring can raise insurance premiums and keep you from using as many appliances as you’d like, the most important issue is safety. Over the course of time, the insulation surrounding the wires will break down until it eventually leaves the wiring exposed. The insulation protecting older wires doesn’t last as long as it does in newer installations. This means outdated electrical systems are much more likely to feature exposed wiring than those installed more recently.

With inner wiring exposed, the likelihood of short circuits and power failures goes up. Worse, deteriorated insulation translates to a much higher risk of suffering from electrical shocks or having fires break out in your home.

If you have any doubts about the wiring in your house, don’t take unnecessary risks. Ignoring the warning signs of an outdated electrical system can put you and your loved ones in danger. Beyond that, whatever money you might hope to save by not calling a professional would only go into repairs later on.

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.
