Energy Efficient Lighting Retrofit Solutions That Save Energy and Costs
Closed Space Control
Unoccupied rooms could be costing you more than you realize. Conference rooms, for example, are typically occupied just 30-70% of the time. Closed offices come in at 35%, while kitchens, copy rooms, and bathrooms can be as low as 10%. Now just imagine how much money you could be wasting by lighting these rooms – which account for roughly 25% of the typical office building – when they are unoccupied. The solution: Vacancy sensors, which have an economic return on investment (ROI) of 52%, a two-year payback and 13% light energy savings.
Daylight Harvesting
Daylight sensors can reduce the total lighting energy in medium-size office buildings by a whopping 70%. In deeper section buildings, daylight harvesting can save 10 to 35% of lighting energy. These sensors have an economic ROI of 21%, a payback of about five years and 30% light energy savings.
Task Lighting
With less than 50% of the average office floor dedicated to individual workstations, and with predominantly computer-based tasks requiring lower ambient lighting, Lower-Task Ambient Lighting can reduce the total lighting energy of a medium-size office building by up to 40%. Task lighting has an economic ROI of 32%.
Blind Management
The right Blinds can increase energy efficiency (reduce lighting energy by 32%), improve natural light control, and reduce glare. New blinds have an economic ROI of 5% and a payback of 19 years, but better blind management has a much quicker payback.
Smart Ballasts
Digitally addressable Dimming Ballasts with automated controls can help bring lighting power density below 1 watt per square foot. Such a project can reduce lighting energy by as much as 65% and carries an economic ROI of 15% and a payback of seven years.
Vertically Integrated Fixtures
The most expensive, yet more effective lighting retrofit available involves Vertically Integrated LED Fixtures with dimming and IP controls. Vertically integrated LEDs combine the lamp, ballast, and fixture as one item. These retrofits can reduce lighting energy by an impressive 85%, and carry an economic ROI of 18%.
