Options for Corporate Energy Efficiency

February 8th, 2010 John Gerace, PhD, PE No comments

There are several rankings and benchmarks for corporate energy efficiency and corporations can perform an energy audit to see where they can improve with their energy usage. Corporations should look into how many kilowatts they use per square foot and how much gas or BTUs are used per square foot. Each country will have average values and recommended values for being efficient.

If you are looking to improve your company’s energy usage you can look into the different products available as each vendor will have information about its products’ energy consumption. For example, glass companies will provide information on their products’ solar heat gain and U-value, and so on.

Many more corporations are creating positions that deal specifically with energy management and many times there is compensation or benefits for those corporations that have good energy performance. There are several different ways in which corporations can make changes to their energy usage and ultimately enjoy big energy savings.

You want to make sure that your building is properly maintained as this keeps it running as efficiently as possible. Small changes can actually cause big changes in energy consumption. One such example is not running the air conditioning at night if no one is in the building. Also you can go through a retro-commissioning process to get your building back to its original state.

Steam systems are frequently an issue with energy usage as they are not maintained well. Steam traps tend to be used to deal with condensation but these can easily become stuck open and transfer the steam back into the boiler. This wastes a lot of heat as the steam goes back into the system and does not heat the building. You need to make sure these are replaced regularly and maintained well.

You also want to optimize your HVAC systems and these can account for 20 percent or more of all energy used in a building. And lastly, you might want to look into thermal energy storage or heat recovery options.

How to Save On Company Electric Bills

February 6th, 2010 William Poulos No comments

Everyone these days is taking a second glance at their utility bills and starting to consider alternative options to lower them. Companies are trying to find ways to cut costs without cutting their staff, benefits, or pay packages. Energy bills have been rapidly increasing and causing even large companies to start thinking of ways to reduce them. If you are trying to save on your company electric bill, here are a few ideas to consider:

A typical building will use most of its energy for heating and cooling purposes. This usually accounts for about 45% of your bill. Since this is the biggest controlling factor, it is a good place to start.

If you can not afford a large scale building management system, try programmable thermostats. Programmable thermostats have been noted to save users up to 30% on their heating and cooling costs. These little devices allow you to program its setting to automatically adjust the temperature at certain times during the day and also when the outside temperature changes. To get the most bang for your buck, look for the Energy Star label on thermostats.

During the summer, you can make use of fans to keep the air flowing. This will make the room feel cooler and allow you to keep the thermostat at a slightly higher setting. Every degree you can keep the temperature setting higher in the summer and lower in the winter will add up to significant savings.

Lighting is another huge chunk of your energy bills, particularly in large business that use a lot of lights or offer 24 hour service. While CFL or LED bulbs are initially much higher in cost than traditional bulbs, they will last up to ten times longer and use 75% less energy! In the end, you will be more than getting your money back out of these light bulbs.

If you are serious about reducing your energy costs, you will need to reach for higher hanging fruit and you should hire a professional energy auditor or engineering firm. Your utility company may even provide a high level energy audit for no initial cost. An auditor or engineer will do a thorough inspection of your entire business and find ways to shrink your utility bills by eliminating unnecessary energy usage and waste. This could prove to be one of the most valuable steps you ever take to reducing your energy costs.

The energy cost center is the easiest to positively impact on any company’s P&L. So get started today!

Energy Efficiency and Your Own Efforts

February 6th, 2010 John Gerace, PhD, PE No comments

There are plenty of things you can do to demonstrate better energy efficiency. Everyone knows the big ones such as recycle and turn off the lights. But there are other small things that can really add up. They may seem odd or like slight inconveniences, but the small magnitude of the inconvenience will completely disappear once it becomes a part of your regular schedule.

The first thing is to unplug all chargers when you are done with them. Many people have their cell phone, camera, or MP3 chargers in the same spot, always ready to go for convenience purposes as we are all always rushing out the door. However, leaving something just simply plugged in can drain electricity and at the same time serves no purpose.

Another thing would be to car pool or take public transportation. These are likewise inconveniences to many people, especially on days when they are running late. However, sticking to a schedule like this may actually make you more punctual and aware of your time. It also can be much cheaper for you. Your car will last longer and your petrol bill will go way down.

You should also start recycling the little bits of plastic you may not even realize can be recycled. For example, many people just throw away the plastic trays from TV dinners. This is hugely impractical, since they can be easily rinsed out and recycled.

Many people throw away lots of little bits of paper like sticky notes, or bits of plastic, like from a candy wrapper. This plastic is merely going to sit in a land fill. Why not put it to good use? These things all add up, so we need to be smart about them. If everyone merely took a step back and looked at what they were really wasting–and knew the life of an object after it was thrown away–people would save so much more in terms of recycling and reusing

Going Green Can Save You Massive Amounts Of Cash!

January 27th, 2010 Robert Holdsworth No comments

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.

In addition to cost concerns, companies are often interested in knowing how energy reduction programs will affect their operations. A professional, well designed system should improve lighting quality, enhance occupant and employee comfort, reduce wear and tear on system components and improve equipment performance.

So again, the answer is, “You can’t afford not to go green”.

Green Energy Strength for Industrial Power

January 7th, 2010 Robert Holdsworth No comments

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.

So what about commercial and industrial facilities using power factor correction to reduce energy costs? It is perfectly appropriate for a company that is incurring penalties or a kVA billing structure from the utility company to improve the facility’s overall power factor by employing a capacitor bank at the main service entrance or individual capacitors at or near the respective motor loads. Doing so will eliminate the power factor penalties and/or reduce the kVA demand charges on the utility bill which can save significant money and provide a significant ROI on the investment.

But what about power factor correction reducing kWh consumption? IEEE also tells us that I2R losses only account for 2 to 5% of the total load in a facility. Simple math tells us that it would be against the laws of physics to get the 15% to 30% energy reduction claimed by some vendors. Think about it. Even if your facility had 5% distribution losses and you could correct 100% of the problem via power factor correction at every load (which can’t be done) you would still only save 5% at the most. No where near the claims of some capacitor vendors and manufacturers.

All that said, power factor correction when done properly will eliminate utility penalties and kVA demand charges, improve facility power quality, increase electrical system capacity, and save a little energy when applied to the appropriate motor loads.

So make an investment in transient voltage surge suppression and power factor correction when appropriate and necessary. But caveat emptor!
