Energy is lost through windows while heating and cooling interior spaces. Double-paned windows can save energy and money. Energy Star labeled windows are twice as energy efficient as the average 10 year old window. They can reduce energy bills by up to 15% in hot and cold weather. The cost for an average window size is in the range of $600 and $850 or approximately $0.50 per square foot. The following are some tips for investing in energy saving windows.

Tip 1: Invest in Energy Star Labeled windows.

Tip 2: Look for the window performance, as certified by National Fenestration Rating, as per climate conditions.

Tip 3: For colder climate, a rating value of 0.35 or below is recommended by EERE.

Tip 4: For warm climates, look for doubled glazed windows and spectrally selective coating.

Tip 5: Choose windows with 0.3 cubic feet per minute or less of air leakage rating.

Tip 6: For locations with heating and cooling seasons, select windows with low U-values and low Solar Heat Gain Co-efficiency.

Tip 7: In order to install the windows correctly, choose qualified and a reputed window installer.

Small crevices and cracks around doors and windows let air flow in and out. This air leakage can contribute over 40% of energy losses in a building. Weather-stripping gaps along windows and doors can effectively save you energy in winter and summer. Insulation projects are cost effective and pay off in less than a year.

A) Test your office for air leaks. Check door and window frames, phone lines, air conditioners, vents and fans.

B) Before weather-stripping the door, make sure the door latches properly. Make sure the hinges do not have loose screws. Clean the surface. Select weather-stripping material that will stay flexible with the changes in the weather conditions. Choose appropriate door sweep and weather-strip the entire door jam. Use continuous stripping on each side such that they meet tightly at the corners. Click here for EERE’s weather-stripping guide.

C) Weather-strip the sash and the frame of the window. Make sure it does not interfere with closing or opening of the window.

D) Insulate air ducts in unconditioned spaces such as garages, unfinished basements, and attics.

Compact Fluorescent Light (CFL) bulbs give out mostly light and very little heat. CFL bulbs use 70% less energy and last 10 times longer than regular light bulbs. Depending on the size of the bulb, CFLs can save $30-$100 over their lifespan.

A) Check with your utility for rebates on replacing existing bulbs with CFL.

B) Buy Energy Star CFL bulbs.

C) Start by replacing one bulb with CFL.

D) Purchase a CFL bulb (with Energy Star label) whose wattage is one-quarter of the existing bulb you want to replace. For example, a 15-watt range CFL bulb replaces a 60-watt incandescent bulb. CFL bulbs cost as low as $1.50. Click here to view the Energy Star guidelines on CFLs.

E) Try out the CFL bulb for its light color. Bulbs that are labeled ‘soft’ or ‘warm’ white give the soothing yellowish glow usually associated with incandescent lighting. Those labeled ‘cool’ white (3200K-4000K) give out a bright white light, while ‘daylight’ bulbs (400K+) produce the harsh bluish tones.

F) For dimmer-controlled lighting fixture, read the package carefully. Look for three-way CFL bulbs. Most CFLs do not work with dimmers.

G) CFL bulbs contain tiny amounts of mercury. Carefully recycle them. Read the EPA guidelines on CFL recycling.

Overheating and overcooling costs you money. As per the Rocky Mountain Institute, you can save 2% in energy cost for every 1 degree lowered on the thermostat. So why not reduce energy used for heating and cooling?

A) Set the thermostat to 78°F to 80°F in summer months. Save on cooling costs of about 4% to 8% for every degree raised.

B) Set the thermostat to 68°F in winter months. Save 2% or more on heating costs for every one degree lowered on the thermostat. Wear appropriate clothing to suit the season.

C) Invest in a programmable thermostat. Typically a programmable thermostat costs between $30 and $100. Click here to view thermostat products.

D) Set time clocks for usage on the thermostat. Program it for the place when unoccupied.

E) Use locking covers to avoid tampering of the temperature settings.

F) Turn off the thermostat when not in use especially weekends and holidays. You may also turn it off half hour before leaving the office.

Turning off lights after use reduces your electricity bill. It’s probably the easiest way to save money.

A) A normal bulb uses 60 watts of energy in an hour. The same bulb when switched off can save nearly 22,000 watts or 22 kW energy per year! Considering electricity costs $0.10 per hour, you could save $2.2 for switching off one light for one hour every day throughout the year. For eight hours when not in use and switched off, the same light can save you $18 per year and $180 if there are ten such lights. These savings can go up if the lights are switched off on weekends and holidays. Now imagine how much money and energy you are NOT saving by keeping lights on after work or on weekends and holidays. Also, nearly all incandescent bulbs use 10% to 15% of electricity to produce light whereas the rest is turned into heat. So turn off the lights if you are not going to return in five minutes. Make sure your lights are turned off on weekends and holidays.

B) Stick a note at every lighting switch like ‘turn off the lights’ or ‘Don’t forget to turn off the lights’ to remind people. Or purchase posters and stick them up in the office.

C) Ask yourself how many lights you need. Do you need the decorative lights? Maybe you need a task light instead of lighting the entire room. A regular lighting bulb consumes 60-100 watts. Get rid of fixtures not in use.

D) Place your work area near the windows and use natural light. You don’t need a lamp when the room is sunlit. Consider using daylight dimming controls. These devices lower artificial light depending on the ambient natural light. According to the EPA, daylighting controls can boost energy savings by up to 40%. Corridors, open cubicles or private offices near windows can effectively use daylight dimming controls. Solatube Daylight Dimmers may cost between $180 and $250.

E) For areas that are not occupied continuously such as conference rooms, break rooms, individual offices, hallways or basement, install occupancy sensors. The occupancy sensors will automatically switch the lights on/off when you enter or exit the room. Occupancy sensors can eliminate 20% – 80% of lighting energy costs. An occupancy sensor will cost between $50-$100. They are easy to install; if you can replace a light switch, you can install an occupancy sensor.

F) For exterior lighting, use motion sensors. Whenever anything moves within the range of the sensors, the area will be automatically illuminated. Make sure your exterior lights are switched off in the day. A timer can also be used to control the exterior lighting. Lumapro motion sensors cost over $25.

G) According to Future Forests, only 5% of the power drawn by cell phone chargers is actually used to charge phones. The other 95% is wasted when you leave it plugged into the wall, but not into your phone. Turn off or unplug the phone and other battery chargers.

H) A typical desktop computer consumes 65-250 watts whereas a laptop 15-45 watts. Set your computer in energy saving mode. Make the power settings to go into sleep or standby mode within 15 minutes of inactivity. Click here to learn how to set the computer. Turn off the computer at the end of the day. Consider using a laptop computer.

I) Turn off printers and copiers when not in use. A printer uses 10 watts in standby mode. Electronic devices with LCD screen and clocks use energy even when not in use. Stick an energy saving poster near the printer and copier to remind yourself and others.

Energy Efficient Lighting Summary

The 2005 Energy Policy Act regulates and mandates energy-efficient lighting systems. It provides accelerated tax deduction incentives to commercial building owners for energy savings achieved through energy-efficient interior lighting upgrades. The lighting upgrade projects must be completed from 2006 through 2008.

Through lighting upgrades to energy efficient systems a commercial building owner can claim up to 45% tax deductions along with 25%-40% energy cost savings with a payback period of less than 3 years.

Here are some details and highlights of the program:

• It reduces the overall taxable income.
• For example, suppose your total taxable income is $10,000 and the lighting tax deduction incentive available to you is $1000. After taking advantage of the incentive your total taxable income becomes $9000. So you now pay tax on $9000.
• This tax deduction allows a company to write off a significant portion – up to 60 cents per square foot – of a capital investment in an energy efficient lighting system in the year it was installed. (Capital Investment refers to money used by a business to purchase fixed assets, such as land, machinery, or buildings.)
• The energy requirement for efficient lighting system is related to the savings in energy in terms of Lighting Power Density.
• The Lighting Power Density is calculated as watts-per-square-foot. For a given space with multiple lighting systems, the Lighting Power Density is calculated as the total wattage of all the lighting systems present in that space (square foot).
• To qualify for the tax deduction incentives, the Lighting Power Density savings of a commercial building after lighting upgrades must be of 25%-40% below the energy standards set in energy efficiency code ASHRAE/IESNA 90.1-2001.
• To clarify, this tax deduction incentive is in the range of $0.30 to $0.60 per square foot proportional to Lighting Power Density savings of 25%-40% below ASHRAE/IESNA 90.1-2001.

Definition

Cap and Trade is a market-based climate strategy for reducing greenhouse gas emissions. The environmental regulator establishes an aggressive limit or cap on the amount of emissions from a group of polluters such as power plants. The amount of cap is then divided into individual permits or allowances in terms of tons of carbon. Companies have to reduce emissions and meet the allowed permit. Those who cannot can buy permits from those companies who successfully reduce emissions.

Design features

A well designed cap and trade program may have the following features:

• strict limits on emissions for pollution reduction
• fixed number of allowances or permits for each polluter
• incentives for pollution reduction
• high standards of compliance and transparency
• compatibility with local programs
• flexibility for polluters to decide when, where and how to reduce emissions

Energy Star for buildings is a rating system for evaluating the energy performance of the building. On a scale of 1-100, commercial and industrial facilities having an energy performance score of 75 or above are labeled Energy Star.

Energy Star labeled buildings on average use 35% less energy and emit one-third less carbon dioxide.

The Energy Star Labels for Buildings is jointly led by the Environmental Protection Agency (EPA) and Department of Energy (DOE).

Eligibility for Energy Star

The following types of buildings and facilities are eligible for Energy Star labels:

• offices
• bank branches
• financial centers
• retailers
• courthouses
• hospitals
• hotels
• K-12 schools
• Medical offices
• Dormitories
• Warehouses
