Maximize Energy Efficiency: System Design & Equipment Selection
One of the best ways to reduce lighting power is to install lighting only where it is needed. There are many aspects to quality lighting, but as a designer, we should always be aware that lighting systems do not necessarily need to rely on permanently installed ceiling systems to generate all lighting. For instance, task/ambient systems provide permanent ceiling or wall mounted lighting systems providing a general “ambient” level of light and rely on work station “task” lighting to supplement the ambient light producing the resultant recommended levels only where they are needed.
It is generally accepted that room surfaces using light finishes can also produce more pleasant environments. Carefully integrating daylight into the space not only improves indoor environmental quality, but may provide the opportunity to eliminate permanently installed lighting or at least reduce the amount of permanently installed lighting or the amount of time electric lighting is needed by the use of automatic controls.
Lighting systems (lamps and ballasts) and luminaire distributions continue to improve, providing additional strategies for reduced energy consumption.
One notable example is within the T8 lamp product segment. Standard T8 lamps with commonly used “standard” electronic ballasts are being replaced by LED tubes with either multiple ballast compatibility or direct-wire options. Both offer up to 50% more lumens/watt, as well as reduced maintenance costs and replacement cycle.
Additionally, utilizing integral LED products in the design phase can significantly reduce initial construction costs and the overall lifecycle costing for the building (this includes: single-family residential, multi-unit residential and commercial). Our experience has proven that incorporating integral LED lighting into a multi-story residential development in the common areas, during the design-phase, lead a construction savings that was equal to the cost of the lighting that was specified.
