Lighting Products
Reduction of energy consumption via the introduction of lighting energy efficiency is simple, cost effective and produces great energy savings. More importantly, lighting energy efficiency is very easy to implement, savings are simple to calculate and the payback period on many lighting projects is very attractive.
Your target for energy savings coupled with your budget will determine the budget size and complexity of the project. Blue Green Engineering offers the following lighting solutions:
Lighting controls
Lighting controls range from simple analogue controllers to advanced digital lighting controls. The main function of lighting controls is to switch off lights or reduce lighting levels according to various external factors when artificial lighting is not required. Lighting controls may also be used to improve the ‘daylight harvesting’ features of a building.
Total lighting solutions
Total lighting solutions are necessary when an existing lighting layout of a space cannot deliver the required lighting levels or the required energy savings. Existing poor lighting design may be attributed to original (possibly outdated) design, to changes made to the internal space fit-out layout or to changes to the immediate external environment (e.g. the construction of new tall buildings that may block solar access). Whatever the condition of your lighting layout, Blue Green Engineering can reduce lighting energy consumption and maintain or improve on existing lighting levels.
Daylight solutions
Blue Green Engineering can provide solutions that combine the use of daylight and artificial lighting. The incorporation of daylight is very important and studies have shown that daylight improves people’s mood and their productivity.
LED lighting
The technology for LED (Light Emitting Diode) lighting has matured and the price has decreased. There are LED light replacements for residential applications. There are LED light replacements for halogen downlights, fluorescent tubes, incandescent lights, floodlights and industrial-type high bay lights.
By changing all existing lights in the home to more efficient LED options, the energy bill can be reduced by up to 40%, depending on the size and layout of the home. Energy efficient LED lights consume 85% less power than standard halogen downlights and outlast halogen downlights by 10 times. Hence, LED lights do not only save energy, but they also reduce maintenance work (see adjacent table).
Comparison between LED lighting
