Business Ways To Save

With all the hype about “going green,” you may have already started replacing household cleaners with organic ones or maybe you’ve even traded in that gas-guzzling car for a hybrid, but why stop there? Check out some office-greening opportunities below. The possibilities are endless!
11/28 Update under #4

1. Replace petroleum-based ink with soy-based ink
Ink made from soybeans is not only better for the environment but better for your company’s bottom line, as well. Soy ink has lower levels of volatile organic compounds than ink made from petroleum, so it emits less harmful toxins into the air. Soy ink produces brighter and sharper colors because of the innate clearness of the soybean oil, which petroleum and other vegetable oils don’t have.

Paper with soy ink is easier to recycle because soy-based ink is easier to remove in the de-inking process of paper recycling than petroleum-based ink. Prices for color soy-based ink are comparable to those for petroleum-based ink, but less soy ink is needed per print job and soy ink reduces paper waste, so you are actually saving money! If those reasons aren’t enough, by using soy-based ink, you are also supporting American crops rather than relying on the foreign oil industry.

Soy ink is currently only available for commercial printers, however, and can’t be used for personal printers or ballpoint pens. Most ink manufacturers produce at least one soy ink, so check with your local ink manufacturer about purchasing soy ink.

Quick Stats

Soybeans only use about 0.5 percent of the total energy that is needed to create the ink.
About 90 percent of the country’s daily newspapers with circulations of more than 1500 use soy ink.
About one quarter of commercial printers in the United States operate using soy ink.
When soy ink reaches its full potential, it will consume 457 million pounds of soybean oil a year.

2. Eliminate vending machine waste
Coffee-making vending machines may save you from caffeine-withdrawal headaches in the morning, but they don’t help out the environment. If your office vending machine dispenses its own cups, make sure they are recyclable or see if the machine allows you to use your own reusable mug instead of dispensing a plastic cup each time it makes a beverage.

Even better, provide machines that allow employees to make their own beverages. This cuts down on waste and energy usage! If you don’t think you can go without a vending machine, however, consider asking the machine provider to de-lamp the machine. This will save a significant amount of energy, considering the lights and ballasts in a typical refrigerated vending machine use about 180 Watts. You can also add an occupancy sensor on the machine that reduces the vending machine’s power requirements during periods of inactivity.

Quick Stats

A typical refrigerated vending machine consumes 400 Watts — at a rate of 6.39 cents per kWh, that’s an annual operating cost of $225.
De-lamping vending machines can save $100 every year.

3. Cut down on office transportation
Offer carpool-matching services that allow employees to find co-workers that live near them. Also, encourage biking and walking to work by providing bike racks outside of the office. Then reward those who do take advantage of these environmentally friendly transportation options! Parking incentives such as parking spots close to the office or shaded/covered parking may entice workers to buddy up for their commutes. Improve e-mail and video teleconferencing capabilities to allow for more telecommuting, and try to provide flexible work schedules for employees, so they can work four 10-hour days instead of five 8-hour days.

Check out Sharetheride.com for a Phoenix-wide carpool matching service provided by Valley Metro.

Quick Stats

Driving 10 percent less, by walking, cycling, carpooling, or taking public transit, can reduce greenhouse gas emissions by 0.2 to 0.8 tonnes per year, depending on the vehicle.
According to AAA, the cost for owning and operating an average size car is 52.2 cents per mile, when driven 15,000 miles per year.
Carbon dioxide is the number one contributor to the greenhouse effect, and cars produce about 30 percent of the nation’s carbon dioxide emissions.

4. Switch out certain light bulbs and monitoring lighting usage
11/28 Lighting A Business - NY only
We obviously can’t work without lighting, but we can do our best to cut down on unnecessary use of lighting, especially in the evenings and on weekends when no one is in the office. Since exit signs are lit up 24/7, they use up a lot of energy and therefore add a lot to your office electricity bill. Make sure all office exit signs are illuminated using compact fluorescent lamps (CFL), light emitting diodes, neon lighting or electroluminescent lighting technology. These will cut down on energy use and lower your electricity bill.

Replace old fluorescent lighting fixtures that are likely using T-12 lamps with T-8 fluorescent lamps. With T-8 lighting, you’ll get better color, less flickering and T-8 lamps use 20 percent less energy than T-12 lamps.

Occupancy sensors are a good idea for areas of the office that aren’t used as much as others, such as the break or conference room. These sensors will detect when a person enters the room and turn on the lights. When they sense no one is in the room, the lights will turn off. These are easy to install and relatively inexpensive.

Visit WattStopper to browse occupancy sensor options.

Quick Stats

Replacing tungsten bulbs with compact fluorescent lamps typically makes an immediate cost savings of between 50-80 percent, and CFLs last up to ten times longer.
Over its life span, a fluorescent tube will save 640 kWh of electricity compared with the equivalent 100-watt standard bulb. This reduces the production of carbon dioxide, a green house gas, by half a ton and sulphur dioxide, which causes acid rain, by 3 kg.
According to a US Department of Energy (DOE) end use study from 1995, lighting accounts for about 29 percent of the energy use in a typical office.

5. Make the most of your office equipment
According to the Department of Energy, office equipment accounts for 16 percent of an office’s energy use. The use of computers, printers, copiers and fax machines adds up, but simply turning your computer’s sleep mode on when you’re not using it can save energy.

It is a myth that activating a computer screen saver saves energy; it actually wastes more of it. In addition to putting your computer to sleep when you are away, make sure to turn the machine off when you leave the office for the night. Certain printers, copiers and fax machines also have sleep modes that can be automatically activated when the machine senses inactive periods. Also, consider consolidating these machines by purchasing a machine that performs multiple office functions.

If you’re looking to purchase new office equipment, visit ENERGY STAR to browse office equipment that cuts down the use of energy and reduces pollution.

Regularly cleaning the coils of your office refrigerator and defrosting the freezer will cause the refrigerator to operate better. It will also operate better if it is kept full, so if you’re refrigerator is too big for the amount of people in the office, fill the extra space with water bottles.

Quick Stats

A Lawrence Berkeley Lab study from 1999 estimated that one workstation (computer and monitor) left on after business hours is responsible for power plants emitting nearly one ton of CO2 per year.
If every US computer and monitor were turned off at night, the nation could shut down eight large power stations and avoid emitting 7 million tons of CO2 every year.
IBM estimates it saved $17.8 million worldwide in 1991 alone by encouraging employees to turn off equipment and lights when not needed.

6. Keep an eye on your paper usage
According to the Environmental Protection Agency, each employee in a typical business office generates 1.5 pounds of waste paper per day. That’s a lot of paper – most of which can be recycled or not used at all. There are several ways to cut down on how much paper you use, but if you must use paper, make sure to recycle it! This will not only help out the environment, but it will also benefit your bottom line.

Ways to use less paper

Make hard copies only when necessary. View documents on your computer instead of printing them out, and use e-mail to send documents rather than printing them or sending them via “snail mail” or fax.
Use a stick-on label on the first page of a fax instead of a full cover sheet.
Reuse paper that only has printed material on one side. Keep a bin for this paper by any printers, fax machines or copiers to use as draft paper.
Make sure all printers and copiers are set up to print on both sides of each sheet of paper. Some older machines may not have this function, but as those machines wear out, replace them with ones that have a double-sided printing function.
When buying paper

Buy recycled paper. Make sure to purchase paper with the highest percentage of post-consumer recycled content available.
Only buy paper that is PCF (processed chlorine free). According to the Natural Resources Defense Council, PCF paper contains recycled content produced without elemental chlorine or chlorine derivatives. Any virgin paper in the product is totally chlorine-free (TCF). PCF paper is preferred over TCF because recycled content is used in the former type of paper.
Use unbleached and uncolored paper. If you need to use colored paper, use pastel colors.
Buy products in bulk to minimize packaging.

Quick Stats

A single-sided 10-page letter costs $0.55 to mail; that same letter, copied onto both sides of the paper, uses only five sheets and $0.34 in postage.
A ton of 100 percent recycled paper saves the equivalent of 4,100 kWh of energy, 7,000 gallons of water, 60 pounds of air emissions, and three cubic yards of landfill space.
In the U.S., over 40 percent of municipal solid waste is paper – about 71.8 million tons each year.

7. Monitor heating and cooling systems and water usage
According to a TIME magazine article, heating, cooling and powering office space are responsible for almost 40 percent of carbon dioxide emissions in the U.S. and eat more than 70 percent of total electricity usage. You can save about 10 percent on your electricity bill by just adjusting that thermostat by one or two degrees.

Ways to save money and energy

Use automatic setback thermostats. These thermostats automatically adjust the temperature settings for weekends and evenings when people are not in the office.
Consider outside air economizers that use outside air to cool down buildings when the air outside is cooler than the air inside.
Think about solar shading. You can use a reflective roof coating and/or window films and shading to reduce the amount of heat from the sun that penetrates your office building.
Keep the blinds closed. In the winter, this will conserve heat in the office, and in the summer, it will keep heat out.
Save on utilities

Add aerators to existing faucets. This can cut faucet water usage in half and save energy when using hot water.
Fix leaks. One dripping faucet can waste up to 20 gallons of water per day.

Quick Stats

Heating, cooling and ventilation accounts for 39 percent of the energy use in a typical office.
An adjustment of only a degree or two can cut heating or cooling bills by two to three percent. Extending that to three or four degrees can produce savings of 10 percent or more.
Water heating in an office can account for nine percent of the total energy load.
Leaky faucets that drip at the rate of one drop per second can waste up to 2,700 gallons of water each year.

8. Consider all of your options
Hire an energy manager or transportation coordinator. It may be beneficial to have someone in the office whose sole job it is to set up carpooling or keep track of office recycling and energy use. The money spent on paying somebody to hold this position will be well worth it when you get your utility bill and help save our planet.

Use non-toxic cleaners or insist your janitorial service use them when cleaning your office. According to the Portland Office of Sustainable Development, cleaning products are responsible for 10 percent of the poisonings reported to poison centers nationally. A lot of cleaners wind up going down the drain and toxic chemicals sometimes then end up making their way into groundwater or waterways. Chemicals from these cleaners also end up in your office air and can have negative health effects.

Join Energy Star to promote energy efficiency. Energy Star is a joint program of the U.S. EPA and the U.S. Department of Energy that looks to help companies save money and protect the environment through energy efficient products and practices. According to the Energy Star Web site, with the help of ENERGY STAR, Americans “saved enough energy in 2006 alone to avoid greenhouse gas emissions equivalent to those from 25 million cars — all while saving $14 billion on their utility bills.”

Make sure all business meetings and conventions follow specific green standards..

Business' Save on Natural Gas Costs

Prices have more than doubled in the last 5 years and are expected to double again with increased demand. We also saw what happens during a major hurricane, with prices going to unprecedented levels during Katrina and well into January.

http://focusonenergy.com/data/common/dmsFiles/B_BP_TRNG_BUS_10718631.pdf


You can reduce natural gas use at your facility. This Focus on Energy action list will
help you get started. If you do not have the expertise in-house, work with Focus on Energy
and local experts such as contractors and product and service providers to complete energy saving projects.
This fact sheet identifies no-cost, low-cost and moderate cost options to increase your
businesses’ energy efficiency. Each step you take will help you manage rising natural gas
costs now and in years to come.

SIX ACTIONS THAT WILL REDUCE NATURAL GAS USE
1. Install setback thermostats or check settings of existing units
2. Ensure energy management systems are working properly
3. Install boiler system controls
4. Maintain steam systems
5. Optimize hot water systems
6. Install heat recovery units


1. INSTALL SETBACK THERMOSTATS OR CHECK SETTINGS ON EXISTING UNITS (NO / LOW COST ACTIONS)
If you have not installed setback thermostats in your small to medium sized facility, you are
wasting energy and money. Install these inexpensive units now. They ensure that you are
not over-heating buildings during non-operating hours. If setback thermostats are installed,
double check their settings and reset them if necessary to match seasonal operating hours
and temperature requirements. You can reduce natural gas use by one percent for every one
degree Fahrenheit you set back the thermostat.
2. ENSURE THE ENERGY MANAGEMENT SYSTEM IS WORKING PROPERLY (NO / LOW COST ACTIONS)
If your medium to large facility has an energy management system (EMS), make sure it is set
correctly and operating properly. EMS often are set incorrectly, which wastes energy and money.
If a qualified staff member cannot adjust your system, hire an expert to do it for you. The
savings will be substantial: you can reduce natural gas use by up to 20 percent by using an
EMS correctly.
3. INSTALL BOILER SYSTEM CONTROLS (LOW / MODERATE COST ACTION)
If your building or process uses a boiler, install system controls. These controls, such as
outdoor temperature resets, manage the boiler's operating temperature. They trim
natural gas use during fall, spring and some winter warm spells. The benefits of installing
boiler controls are substantial: you will reduce the boiler's natural gas use by 15 percent to 20
percent for noncondensing boilers and up to 40 percent for condensing boilers.
4. MAINTAIN STEAM SYSTEMS (LOW /MODERATE / HIGH COST ACTIONS)
Many school, commercial, industrial and government buildings operate steam systems and will save energy by taking the following actions. For example, a typical industrial facility can reduce steam system related natural gas use by 20 percent.
1. Reduce steam system leaks. Repair leaks in steam piping, condensate return lines and
fittings. Wasted steam equals wasted energy.
2. Insulate piping and valves. Examine piping and valves and insulate them. If existing
insulation is damaged, replace it immediately. Uninsulated pipes lose heat and cause the boiler to use more natural gas than necessary.
3. Test steam traps, replace defective traps, and maintain existing ones. Malfunctioning
steam traps waste steam and result in higher boiler fuel consumption. You can reduce your
boiler's natural gas use from five percent to ten percent. Simple payback is often one year or less.
4. Tune-up boilers every three to six months. Do not ignore basic maintenance; keep steam systems operating at peak efficiency and you will manage energy costs more effectively. Routine maintenance can reduce facility energy use by two percent.
5. Implement additional, longer term boiler modifications. Several actions will further increase boiler efficiency. These equipment modifications include: 1) adjusting boiler operations by adding stack economizers; 2) maximizing condensate return; 3) automating blowdown and recovering heat from the blowdown stream; 4) recovering flash steam heat; and 5) installing automatic burner controls. These actions will pay for themselves in one to three years.
5. OPTIMIZE HOT WATER SYSTEMS (NO / LOW / MODERATE COST ACTIONS)
You can take several actions to reduce both natural gas and water use.
1. Minimize use. Many businesses can find ways to reduce hot water use. Install low flow, high efficiency pre-rinse sprayers at dishwashing stations in food service operations, replace
full flow showerheads in lodging facilities and locker rooms with low flow units and upgrade laundry systems.
2. Adjust hot water temperatures. Unless high temperature levels are required by code, set water heater temperatures to 120°F. Each 10 degree Fahrenheit reduction in water temperature will generally save three to five percent on water heating costs.
3. Insulate hot water pipes. Add inexpensive insulation to all hot water piping and reduce heat loss.
4. Install more efficient hot water systems. If you are considering a change, make sure you install energy (and water) efficient units.
6. INSTALL HEAT RECOVERY SYSTEMS (MODERATE TO HIGH COST ACTIONS)
Many businesses and farm operations should consider installing heat recovery systems to capture waste heat from refrigeration equipment, boilers, driers, furnaces and other
manufacturing processes. This waste heat can then be used to meet other heating or hot water needs and displace the need for natural gas. If you already have a heat recovery system, make sure it is working properly.
