PROVEN SAVINGS, QUALITY DESIGN

Saturday, May 16th, 2009

Lighting design, as it applies to the built environment, is both a science and an art.  It is also known as architectural lighting design.  Quality lighting design can improve task performance or the aesthetics of a building or a space, whereas improperly designed lighting can easily result in extreme energy waste, poor aesthetics, an unsafe environment or adverse health and psychological effects.

Savings Though Energy-Efficient Lighting

Lighting includes the use of both electric and natural light sources.

Natural lighting is the most efficient solution for achieving significant energy conservation.  Taking advantage of this natural resource through full height windows, clerestory windows, skylights and controls can drastically reduce building operation cost.

The lighting design team can integrate natural lighting into the design creating more energy-efficient environment and reduce the overall building maintenance.

Electric lighting represents a major component of energy consumption, accounting for a significant part of all energy consumed worldwide.  In homes and offices, from 20 to 50% of the total energy consumed is due to electric lighting.  In many buildings over 80% of lighting energy consumed is an unnecessary expense due to over-illumination.  The annual cost of that lighting and its additional maintenance can be substantial.  For example, a single 100 watt light bulb used just six hours a day can cost over $25 per year to use.
