NPrismatic Skylights with LED Lighting
Nucor’s high performance prismatic skylights, when combined with the use of energy-efficient LED lighting and controls, offers an even higher opportunity for operational energy savings.
It is important that a roof curb be designed for a specific type of roof. Roof curbs that are effective for flat built up or flat single ply roofs can be a disaster when used with standing seam metal roof panels. In fact, even when working with standing seam metal roofing, a roof curb should be designed for the manufacturer’s specific roof profile. Choosing a roof curb specially designed for a specific metal roof profile is critical, and one curb fits all metal roofs can be a prescription for disaster. NBS roof curbs are designed specifically for our roof profiles.
Prismatic Skylights, LED Lighting, and Lighting Controls
Maximum energy savings (up to 75%) are achieved when the lighting system is controlled by both daylighting and occupancy sensors. Experience has shown that in commercial buildings, the manual operation of lights is unreliable and thus an automatic system is required. Lighting systems in nonresidential buildings operate at full output regardless of outdoor conditions. On most days, however, daylight (sunlight through skylights and windows) can provide sufficient light levels for many activities. The results of not dimming electric lights include occupant eye strain due to excessive light levels and unnecessarily high electricity use for lighting and air-conditioning.
Get Maximum Advantage of Daylighting with Lighting Control Systems
Lighting systems, skylights, windows and HVAC systems need to be designed to take maximum advantage of daylighting. When solar gains are at their highest, the building cooling system can be reduced in size because lights are dimmed to the minimum. Daylighting works best with indirect lighting because occupants are less likely to notice changes in electric light output.
Maximum energy savings (up to 75%) are achieved when the lighting system is controlled by both daylighting and occupancy sensors. Combining your prismatic skylights with energy efficient LED lighting and controls can potentially reduce your annual electric lighting energy consumption by 40-60%.
Bringing natural light into your building provides benefits beyond energy savings. Compared to facilities relying solely on lighting:
-
Retailers report up to 40% better sales in daylighted stores
-
Daylit schools see improvements of 20-26% in academic function
-
Office report 10-25% better worker performance, reduced absenteeism, and significantly better morale
Studies have also shown a significant correlation between daylighting and improved performance of office workers, and up to a 40% increase in retail sales. LED lighting can also reduce your total electricity consumption for lighting by half.
