Calculating LED lighting savings can be done by using the following formula:
Multiply the total lighting watts by the number of hours they’re in operation. Here’s an example.
If you have 100 fixtures using 35-watt lamps in operation 14 hours a day for 31 days, the formula to find the total used amount of electricity is; 3,500 watts x 434/1,000 = 1,519 kWh of energy. Depending on the building’s size, it may not seem like over usage until you see the electric bill.
Did you know we have an eBook dedicated to calculating your energy savings and ROI on any lighting project? In this e-book, you’ll find step-by-step guides for calculating energy savings. There are several aspects to consider, but we’ll guide you through each of them. You can download the eBook for free, here. Or click the button below.
How Much is Your Energy Usage Costing the Company?
You know how much energy your traditional fixtures use, but what about the cost? There’s a quick and easy way you can calculate your estimated utility bill.
The national average cost for a kWh of energy is $0.12. Yours maybe a little less or more, but this will give you a general idea.
Multiply the number of kWh you use each month by $0.12 (the national average per kWh) and you know how much the company is paying each month using non-energy efficient lighting.
Waiting to convert to LED lighting can rack up HVAC costs. When alternative lighting, such as halogen or incandescent, produces more heat and the HVAC system has to work extra hard to cool down the building. This can lead to higher HVAC bills, especially if your HVAC system is older and would have a harder time cooling the building. You may be spending money on repairs that are unnecessary with LED efficiency lamps.
You probably want to calculate your HVAC costs and compare your current lighting vs LED lighting. Well you are in luck, we have an entire blog, with formulas, dedicated to calculating your HVAC energy savings in an LED retrofit.
Maintenance and Material Costs
One of the most enticing benefit to LED lamps is they have the longest lifespan on the market. Replacement costs can add up quickly for alternatives when maintenance requires them to be changed 20 to 30 times a month. With the long lifespan of LEDs, they do not need to be changed as often. Even though initial installation may cost more than halogens or other alternatives. Their maintenance requirements will benefit long-term. When the LEDs do finally need to be changed, they can be upgraded to Next-Generation LED lamps to have the latest technology in LED lighting.
If your lamps are reaching the end of their lifespan, then it’s time to consider a next-gen LED upgrade. Click here to read Next Gen LED Upgrades for Facility Managers to learn the signs of when its time for an LED upgrade.
The Soft Cost of Waiting to Convert to LED
LED lighting is a commitment worth taking if you are looking for a lighting option with long-term savings that can help the environment. LEDs even have a wide range of options for brightness and color temperature. Customers are more likely to stay and browse, and this can lead to an increase in sales. A growing profit margin, along with electricity savings, can offset the cost of your lighting upgrade. The soft cost of not considering LED lighting is spending more money constantly replacing cheaper bulbs when they require maintenance. They will also burn more energy and rack up your utility bills.
