Lighting Audit Makes Sense!
Lighting Audit Makes Sense!
Lighting is said to be the biggest consumer of electricity in both commercial and residential buildings. The lighting industry is well aware of this and so is developing new technologies which can reduce costs and increase efficiency of lighting. But the fact is that most of the end users i.e. the building owners, are not well aware about when, where and which lighting technology can be most feasible for them in terms of costs and efficiency.
So if you are one of those building owners who are not sure how and how much you can save through the lighting installations in your buildings, lighting audit is the solution to your problem. Lighting audit tells you where your building is burning money.
How does Lighting Audit Works?
Lighting audit is a subset of energy audit and is conducted by a power or energy expert. The expert will take a detailed round of your building for carefully making observations and taking readings. Make sure you cooperate with him at every step.
The expert will measure the amount of light available in each area. In bigger areas, more than one reading may be taken to maintain the accuracy in each corner. For example in a restaurant, readings may be taken at the entrance, reception, main dining room and corridors etc.
Another important thing which he will observe is the location of lighting installations. Considering the example of restaurant dining room, if lights are hanging between the tables, the amount of light available on the tables would be inappropriate. So lights should be exactly where they are needed. The auditor will make note of this throughout the audit.
The auditor will also notice behavior of the consumers. Do they turn off unnecessary lights? Do they utilize day light and only switch on lights when day light is not sufficient? All these behavioral signs prove to be very important while assessing the potential of energy and cost savings.
Other important factors to be observed are the type of lighting installations being used in the building, type of light switches, wattage of bulbs being used etc.
Once the whole area is covered, the auditor will compile all the information and prepare an audit report based on that information. The audit report will include:
- Total energy being consumed by the lighting.
- Present costs of lighting (including electricity bills and maintenance cost)
- Improvement Plans
Improvement plans will discuss possible ways to reduce lighting costs and enhance lighting efficiency. Lighting auditor will recommend the plan which will give lowest payback period and highest return on investment to the client. In most cases, these plans include actions like replacing incandescent lights with more efficient LEDs or inductions lights, installing occupancy sensors in corridors and washrooms and other conservation technologies.
Based on the lighting audit report, you can most certainly decide the best lighting plan for your building.
Why Go For Lighting Audit?
Lighting accounts for a huge percentage in a country’s total power consumption. Studies suggest that by replacing an ordinary bulb with an energy efficient bulb, a person could save around 12 CAD on electricity bill. It might look like a minute saving but if every home and business in Aurora, Ontario replaces one bulb, it would make a huge difference in terms of both personal and national savings. Therefore, lighting audit is a top priority these days, especially for commercial building owners.
