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

Why You Need Power Factor Correction and TVSS Do Not Save Energy

February 5th, 2010 Robert Holdsworth No comments

In today’s energy climate more and more people have become motivated to accomplish what they can to become more energy efficient to conserve energy and money. Regrettably this same climate has encouraged some to take advantage of innocent consumers’ desires to save energy and reduce operating expenses.

Vendors that advertise power factor improvement (kVAR correction) and transient voltage suppression to save energy are a good case in point of this bad trend. Recently we are seeing more and more of these businesses cropping up and we believe it is time to set the record straight.

First off, transient voltage surge suppression (TVSS) plays an important part in improving power quality to guard sensitive equipment inside a facility. However, TVSS does not save energy. TVSS’s are barely active an infinitesimal portion of a second to defend against voltage surges which only last for less than a millisecond. To actually decrease energy use the TVSS would need to essentially cut power consumption for an extended amount of time which is not what they are designed to do. Again, TVSS is essential to protect susceptible electrical equipment but consumers should steer clear of vendors promising, or even guaranteeing, a reduction in energy consumption.

And what about salespeople who maintain that increasing power factor will save 15% or 20% or 30% of energy consumption and resultant costs? This is false but also a bit trickier.

For homes, power factor correction does zero to save energy because the average home already has an average power factor of approximately 0.97 which is nearly the perfect power factor of 1 or unity. Additionally, the unit (called a capacitor) is installed at the homes main circuit breaker. According to IEEE 5.5.3.3 capacitors must be located at or near the individual inductive motor loads to decrease power system losses by reducing heat and distribution losses known as I2R losses.

So what about commercial and industrial facilities looking to use power factor correction to shrink energy expenditures? It is completely appropriate for a business that is incurring penalties or a kVA billing structure from the utility company to improve the facility’s overall power factor by installing a capacitor bank at the main electrical service entrance or individual capacitors at or near the particular motor loads. Doing so will do away with the power factor penalties and/or reduce the kVA demand charges on the electric bill which can save considerable money and provide a significant ROI on the investment.

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

All that said, power factor correction when done appropriately will eliminate utility penalties and kVA demand charges, improve facility power quality, increase electrical system capacity, and save a modicum of energy when applied at the proper motor loads in an industrial facility.

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

Energy Costs Reduction and Management for Office Buildings

February 5th, 2010 Robert Holdsworth No comments

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!
