LEED Certified And Green Energy Strength For Industrial Power
Today’s energy conscious climate has motivated many to do what they can to become more efficient and conserve energy and money. Unfortunately this same climate has prompted others to take advantage of unsuspecting consumers’ wishes to save energy and reduce expenses.
Companies that tout power factor improvement (kVAR correction) and transient voltage suppression are a good example of this bad trend. Lately we are seeing more and more of these companies cropping up and feel it is time to set the record straight.
First, transient voltage surge suppression (TVSS) plays a valuable role in improving power quality to protect sensitive equipment inside a facility. However, TVSS does not save energy. TVSS’s are only active a tiny fraction of a second to protect against voltage surges which only last for less than a millisecond. To actually reduce energy consumption the TVSS would need to actually cut power consumption for an extended period of time which is not what they are designed to do. Again, TVSS is important to protect sensitive electrical equipment but buyers should avoid vendors promising, or even guaranteeing, that they will reduce energy consumption.
Now what about vendors who claim that improving power factor will save 15% or 20% or 30% of energy consumption and corresponding cost? This one is a little trickier.
For residential applications, power factor does nothing to save energy because the typical home already has an average power factor of about 0.97 which is almost the perfect power factor of 1 or unity. In addition, the device (called a capacitor) is placed at the main circuit breaker. According to IEEE 5.5.3.3 capacitors must be situated at or near the respective inductive loads to reduce power system losses by reducing heat and distribution losses known as I2R losses.

Energy Costs Reduction And Management For Office Buildings
Office buildings are significant energy consumers using an average of 17 kWh of electricity and 32 cubic feet of gas per square foot. Moreover, industry data indicates that energy costs are 20% of the typical facility’s annual operating budget.
As energy costs continue to increase, businesses are discovering the tremendous financial, operational and competitive value of energy cost reduction and improved energy efficiency.
Because HVAC and lighting comprise 65% of combined energy use in office buildings (47% and 18% respectively), they are where you should initially focus your energy reduction efforts. By centering on these key areas, companies have significantly improved energy efficiency while maintaining or improving occupant / employee comfort and productivity.
Because each facility is relatively unique, using a carefully planned “whole facility” approach, allows you to be confident that you are making the best, most financially and operationally prudent energy efficiency choices. You will find there are proven and recommended engineering approaches and technologies available that can guarantee results and by working with an experienced, energy services company or engineering firm, choosing the right options does not need to be complicated. Deciding where and how to begin can be fairly straightforward. The best first step is always to focus on quick, low cost or no cost solutions. This can include training staff to turn lights off when they leave unoccupied rooms, using occupancy sensors in offices, conference rooms, etc., using sleep mode settings for computers and other electronics when not in use, setting back thermostats during overnight and closed hours and having the HVAC systems serviced and cleaned on a regular basis. After you’ve addressed the “low hanging fruit”, next steps can involve choosing from a variety of longer term options that are designed to deliver much greater energy savings. Options should be considered based on their proven track record of success, whether they are “approved” or “recommended” by organizations such as Energy Star, US DOE, USGBC, IEEE, etc., their cost effectiveness and return on investment as well as their consistency with your company’s goals and culture. Some of the best options for office buildings include lighting upgrades to high efficiency fluorescent, CFL and/ or LED, use of occupancy sensors and day-lighting opportunities, sine wave modification for outdoor lighting circuits, liquid pressure amplification for central chiller plants, anti-compressor short cycling for roof top units, use of variable frequency drives, building management systems, reflective roof coatings and possibly equipment replacement for older equipment that is approaching the end of its useful life.
As you proceed with implementing energy efficiency measures, know that you don’t have to do it alone. There are experienced firms that can help make recommendations and provide turnkey services for you. In choosing a partner to guide this type of “whole facility” approach for you, it is important to look at a number of factors. You may want to ask the following: What is their level of experience using these various technologies, do they use proven and recommended approaches, what are the credentials of their staff, are they members of key industry organizations, what is their level of knowledge of your industry, do they offer a free initial evaluation and do they offer guarantees at each step of the process. Remember, the sooner you begin, the sooner you start saving your organization’s valuable and limited resources and improving your company’s profitability!

Going Green Can Save You Massive Amounts Of Cash!
The Question: “How can we afford to “Go Green?” The Answer: “You can’t afford not to!”
As companies and institutions everywhere are asking, “How can we afford to go green?” Others have learned that the real question should be, “How can we afford not to?” Between the savings from energy efficiency, government incentives, rebates and well structured financing and lease options, energy projects can be excellent investments rather than daunting expenses.
By taking a carefully planned “whole facility” approach, companies can target both the “low-hanging fruit” (such as lighting upgrades and maintenance solutions) and a combination of other equally significant and cost effective solutions (such as available technologies to improve the efficiency of HVAC, refrigeration, equipment loads, etc) to achieve substantial returns. The efficiency gained across multiple load categories will amass to very significant reductions in overall energy consumption and costs. Often, these savings can help to fund more expensive, longer term solutions. Experts all agree that increasing energy efficiency is the most important and financially prudent step any business can take in “going green”. By reducing demand and consumption first, the scope and cost of secondary phases (such as adding renewable energy sources) can be better controlled.
Many government and utility programs have been designed to reward companies following just such an approach. For example, New Jersey’s Pay for Performance program returns up to 100% of the money spent for design and 50% of the money spent for implementation which significantly reduces payback time and increases R.O.I.
Furthermore, equipment lease or rental agreements can be used to eliminate out of pocket and capital expenditure costs and immediately enrich cash flow. Structured properly, these agreements cover the entire project cost and have such low monthly costs that they are off-set by the savings. In other words, the monthly energy savings outpace the monthly lease payments creating additional, immediate, unexpected cash flow and profit for the facility.
