Efficiency Controls for Commercial HVAC Cut the Costs of Electricity More than 50 Percent

With the controls, advanced energy-efficiency, the commercial building can easily cut by an average of fifty-seven percent their HVAC (heating, ventilating and air conditioning) electricity use and the result found by a trial (year-long) of advanced controls at different commercial buildings, grocery stores and malls across the country. The PNNL (Pacific Northwest National Laboratory) of the Department of Energy conducted the study and demonstrated that the Commercial HVAC saved higher energy than a prediction.

The HVAC boxes called as packaged units (HVAC) placed on the roofs of some commercial buildings. These packaged units (HVAC) consume pretty equal amount of energy of 2,600 trillion (British) units (thermal) or 8 million residents (U.S.).

Srinivas Katipamula, the lead researcher of the study and his PNNL colleagues found that air handling units (HVAC) have better controls in case of using packaged units (rooftop HVAC). Based on the conditions outside and inside of a building, they tried to adjust the operations with packaged units automatically. Using variable-speed motors and sensors, the controls determine how fast and when should ventilation fans run and make sure the units can use cold air naturally in lieu of indoor mechanically cooling air.

Actually, everybody knows that heating & cooling consume a huge amount of energy as most of the buildings don’t have sophisticated control systems. However, if the advanced controls are properly installed at working, real commercial building, then the energy efficiency of the air conditioning systems clearly demonstrates its true performance and energy-efficiency.

The PNNL team was working with various controls and some companies started developing and processing advanced controls in the meantime. The PNNL team installed some energy-efficient and commercially available HVAC units (rooftop) at some commercial buildings. They were amazed to see the results as it cuts almost 57 percent of energy on an average in comparison with standard operations. In fact, the range was 20 to 90 percent (energy savings). However, the bigger buildings (or malls) saved more energy compared to smaller buildings. Moreover, the stores (that ran ventilation) save more energy as these are usually open relatively long hours.

In fact, the researchers found that the HVAC units or advanced controls would help to save a lot of money every year for the building owners. This is for sure that the owners of the buildings would be inspired by the figures and install the advanced controls for greater savings.

Electrical Safety After A Natural Disaster

Unfortunate though it may be, natural disasters are part of life. Though many of us do not like to think about what might happen in the case of a natural disaster, it’s important to be prepared for a worst-case scenario. Natural disasters can be particularly damaging when it comes to your electrical system. It can be dangerous dealing with restoring electricity if your power should go out during these times. Here are some things you should know if your power goes out as the result of a natural disaster.

Although you may not want another thing to deal with after a natural disaster, an electrical inspection may be necessary. If your electrical system has been flooded or if your electricity has not been turned on by your utility company because of the damage to your system, an inspection may be required. If you are replacing damaged equipment, electrical supplies or wiring, it may be necessary to get an inspection for those as well. Requesting an inspection may seem like a major inconvenience when you are trying to recover from a natural disaster, but being safe must be the priority here.

If you have electricity in your home, it may still be a good idea to get a licensed electrical contractor in to inspect your system to make sure everything is safe before turning your electricity back on. There could be damage to your system that may be hidden from view.

If it is determined that no damage was done to your home, you should still call your electrical utility company to get your power turned back on. They may require an Agency Request Inspection before doing so. This is a free inspection.

If your area is declared a disaster area, and there was flooding to your electrical system, you will need an L&I Agency Request Inspection. If no electrical problems are found, the utility company will be given the okay to turn the electricity back on.

If damage to your system was found, you will be given a list of what needs to be repaired. Then you will need to obtain an electrical permit for the repairs. Once repairs are made, you will need to get your L&I Agency Request Inspection. If there is no damage found at that time, the utility company will be given the okay to turn the power back on in your home.

At times, although it may seem like the damage to the electrical system in your home are an easy fix, it is always best to trust those repairs to a licensed electrician. He or she will know what is necessary as far as what electrical supplies to use to repair the system. Many electricians purchase supplies at electrical wholesale outlets. Electrical supply stores online are another good option.

When natural disasters happen, they can be devastating. However, it’s always best to be prepared. Hopefully, these tips can help you get back on track if a natural disaster hits your area.
