This lighting circuit needs to be modified and controlled by a photocell. Calculations indicated that corrective action would save more HK$2,700 per annum.

Conclusion

We realize that HK$ 2,700 is not a significant amount, however energy audits idendify hundreds of small costs savings, and together that is a consderable sum every year!

Plus, if operated correctly the lamps would not require frequent replacement, increasing the lifespan.

Since operating requirements and characteristics of buildings are not static, they vary throughout the life of a building, its a timely reminder to conduct an energy audit. Call Kelcroft to order your energy audit today!
