Energy Audit Case Study III
This energy audit case study is a sanitized part of an energy
audit conducted in Hong Kong. It
is only one element from comprehensive
energy audit report covering several buildings on the site conducted by
Kelcroft E&M Limited.
Date: July 2008
Location: Hong Kong
Type: Leisure (club house buildings)
A Kelcroft energy audit uncovered several opportunities to conserve waste energy, lower operating expenses and save money. One particular discovery, is an interesting an example.

The
Kelcroft energy audit uncovered an alarming
fact all the external lighting fittings that could be described as
security lighting were operating day time hours.
Synopsis
A new building in the complex that had been commissioned only months before was found with external lighting fittings operating during a bright sunny afternoon.
Designer note: Actually this is type of problem is a common, it results from the design stage and a poor understanding of building operations.
Numerical Analysis
Energy auditing is economics driven activity, the goal of the
energy auditor is to identify
feasible energy opportunities and provide cost savings.

Calculations indicated that corrective action would save more than HK$2,700 per annum. This lighting circuit needs to be modified and controlled by a photocell.
Conclusion
Now we all realized that HK$ 2,700 is not a significant amount the entire audit found hundreds of EMO.
However if the lamps where only operated correctly only during dark and night time hours the lifespan would increase by 100%, and therefore lamps would not require replacement saving expensive labour charges and the cost for replacement lamps.Since operating requirements and characteristics are not static, and vary throughout the life of a building, is a timely reminder to conduct an annual energy audit.
