Kelcroft Lighting Audit
BY John Herbert
Fluorescent fittings are the predominate choice for lighting systems in commercial buildings, they are an excellent energy efficient light source for the built environment. The majority operate up to 20,000 hours with high efficiency (high lumens per watt) and provide acceptable colour rendering.
Increasingly LED type lamps are gaining acceptance because the life span of the lamp is significantly longer and lower power consumption.
replace inefficient lighting, you will save money on your energy bills and help save the environment too
In commercial office buildings, the lighting systems account for more than 15% of the energy consumption and provide significant opportunities for energy reduction without influencing the indoor environment for the occupants.
Kelcroft's on site lighting audit expertise identifies those energy and cost savings.
Lighting Level
What is the right quantity of light? We use the term LUX to describe lighting level for a room or corridor. The higher number equates to higher intensity.
For
a typical office general lighting level of 500 Lux would be satisfactory,
for a corridor or other transient areas 200-300 Lux would adequate.
However, often Hong Kong offices have more than 1000 Lux
(actually recorded at working surface).
Having the poor lighting
system causes occupants to suffer discomfort and additional
eye strain, so having the right level is critical for your productivity.
Lighting Audit Process
Using our own instruments we physically measure the existing lighting level and record our findings. When excessive illumination is record, we make recommendations to reduce/upgrade the lighting system to the recommended level saving money and saving energy.
The lighting level in perimeter
areas that enjoy natural daylight can have lower levels of
electric lighting during bright days.
Pollution Prevention P2
After contamination, removing the offending pollutant from the environment is very expensive proposition. Consider the costs for cleaning contaminated waste water or land after a spillage, it's tough to execute and expensive. A P2 strategy prevents pollutants entering the environment, it smarter and lower cost strategy.
How
can we reducing or minimizing environmental pollution from florescent
and CF lamps?
All the major lamp manufacturers offer a low mercury (sometimes called eco-friendly) lamp, some are branded with a green end cap. However, green or otherwise each still contains a small quantity of mercury, and demands careful handling and disposal to prevent mercury contaminating our environment.
What next?
Replacing inefficient lighting will save money on your energy bills and reduce environmental impact. For further information contact the energy experts call Mr John Herbert at our Hong Kong office - telephone (852) 2335 9830 today to order your lighting audit.
