Energy Savings – Part 1
In this tight economy, businesses are increasingly looking for ways to cut operational expenses and provide service to their customers. One area that offers opportunities to save now is lighting for your offices and buildings.
Each CFL bulb installed saves an average of Rs. 500/- in energy costs, 50 kilowatt hours and 75 pounds of carbon dioxide emissions per year.
Below are some tips for when purchasing CFLs:
1. Choose only nationallay recongnized CFL, ensure it has been tested and certified to the applicable standards for safety and performance. A certification mark should appear on both the product and the packaging.
2. Choose an Energy Star qualified CFL to ensure it will provide the greatest amount of energy savings. Energy Star Qualified CFLs also have a minimum two-year warranty.
3. Choose the bulb that best suits the fixture. CFLs with globes are available in various sizes and shapes to fit most fixtures. They look similar to traditional incandescent bulbs and may look better in fixtures with exposed bulbs.
4. Determine how much light is needed. Check you fixture to ensure the light is the proper size and wattage. Light output is described as “brightness” and is measured in lumens.
Below sample calucation is for one CFL comparing with one regular bulb
Assumptions
100W GLS being replaced with an 18W CFL
No. of hrs of usage per day – 5 hrs
Per annum calculation days – 350
1unit (1 KWH) cost of electricity – Rs 5 per KWH
Sample Calculation
100 W GLS being replaced with an 18 W CFL
Savings per lamp = 82W
No. of hrs usage per day = 6 Hrs
Therefore no of hrs usage per annum = 2100 Hrs (6*350)
Therefore electricity saved per annum = 172200W hrs (82*2100)
Therefore electricity saved per annum = 172.2 KWH
Therefore Amount in Rs saved per annum = 861 Rs. (5*172.2)
