Daylighting
What is Daylighting?
Scientifically, “Daylighting” is the use of direct, diffused or reflected sunlight to provide lighting for building interiors. Allowing more daylight into classrooms and workspaces is a proven renewable energy technology that saves money, increases worker health and productivity – and it improves the quality of your workspace!
By adding a Daylighting System to your building, you can introduce natural, bright light to the work area while significantly reducing power use. In fact, incorporating Daylighting reduces traditional lighting and HVAC costs resulting in a potential payback of two to three years.
What types of Daylighting does Pfister Energy offer?
Pfister offers two types of Daylighting – “Passive” and “Active”. Passive Daylighting systems include specialized translucent window glazing (not tinting) and sophisticated skylight systems. Window glazing eliminates glare while distributing light evenly and deeply into the work area. Daylighting skylight systems use an engineered system of mirrors and reflective surfaces to efficiently light your work area while insulating from heat and protecting from glare.
Active Daylighting systems add intelligent controls to skylight/well systems. These controls are tied into your interior lighting system and automatically turn the electrical lights on, off or adjust them to compensate for the amount of sunlight that can be captured. By installing an advanced rooftop window that can take advantage of low light levels and low sun positions throughout any season, you can maximize natural daylight in your building from morning until night.
What are the benefits of Daylighting?
The clearest effect is reduced energy usage. Electrical lighting can account for up to 25% of a building's energy costs and electrical lights produce a significant amount of heat burdening the air conditioning system. By reducing the combined load of lighting and air conditioning, you can use less power especially during peak afternoon work hours.
Other benefits include:
 |
| • |
Reduced operating expenses (40-80% of lighting) |
| • |
Reduced electric lighting maintenance costs |
| • |
More constant light level |
| • |
Adjustable light levels to match demand (“active”) |
| • |
Optimized natural light throughout the day |
| • |
Bring natural light indoors |
| • |
Increased consumer sales |
| • |

Who can use Daylighting?
Daylighting design can be incorporated as a retrofit lighting system or incorporated in new construction. Whether the building is low-rise or high-rise, industrial, institutional or commercial, Daylighting systems are proven renewable energy methods. In fact, Daylighting is successfully lighting these building types:
 |
| • |
Factories and production facilities |
| • |
Offices and staff rooms |
| • |
Retail stores and supermarkets |
| • |
Printing and silkscreen facilities |
| • |
Auto dealerships |
| • |
Hospitals |
| • |
Government, municipal and military facilities |
| • |
Restaurants |
| • |
Warehouses and hangars |
| • |
Fire stations |
| • |
Gymnasiums, cafeteria, libraries and schools |
| • |
Churches |
| • |
Bottling and canning facilities |
Bottom-Line Profits and ROI
Just to start, Daylighting can eliminate approximately 2.5 million watts of electric lighting per year resulting in a payback from energy savings alone of 2-5 years. The same retrofit may cut energy use by 50 cents or more per square foot, significantly affecting the Net Operating Income (NOI) of a building or facility.
Daylighting systems offer excellent opportunities for energy savings, while improving the quality of the space and offering the occupant a visual connection to the outdoors. Daylighting systems use a combination of technology and architecture to transform your building into a visible illustration of energy efficiency, as well as a more comfortable and pleasant visual environment.
