The end Thank you
Why we need daylighting
• Using daylighting can minimizes the need for lamps and overhead lights and the energy required to power artificial lighting.
பைடு நூலகம்
Thin slices guarantee interior spaces gain enough light, also control glare.
• Shutter provides indirect light and reduce glare for exterior spaces.
Achievements in Energy Efficiency
• reduce the projected overall energy cost for the building by about 41%. • reduce the electrical demand for lighting from 365 kW to 260 kW on hot summer days.
Daylighting
Introduction and a case study on Genzyme Center
By zhou zhou 063477
What is daylighting
• Daylighting in a building utilizes available sunlight by manipulating window placement, window fixtures, and room dimensions to maximize natural light in a space.
• Effective daylighting techniques also can: - balance heat gain and loss, - control glare, - cut energy costs, - creat a comfortable environment within any building.
Approaches for daylighting
A case study
Genzyme center
• • • • • • • • Location: Cambridge, MA,USA Building type(s): Commercial office New construction 344,000 sq. feet (32,000 sq. meters) Project scope: 12-story building Urban setting Completed November 2003 Rating: U.S. Green Building Council LEED-NC, v.2/v.2.1--Level: Platinum (52 points)
Daylighting for Energy Efficiency
– Design an open floor plan to allow exterior daylighting to penetrate the interior – Use atrium for daylighting – Use building elements to redirect daylight and control glare – Use skylights for daylighting – Use light pipes and/or active tracking skylights for daylighting

How it works to obtain daylighting?
Optical collection and distribution system
Skylights system
-redirects daylighting . -improves light distributions.
