Daylighting+Design+Performance

Daylight Design Performance
Lighting Power Density: The ratio of lighting power to square footage measured in w/sq.ft

Corrugated Steel Roof 1'6"- .0032(18) = .058 Double Air Filled Glass - .14(2) + 5.6 = 5.88 Concrete 2' Wall - .7(24) = 16.8
 * R-values of materials**


 * Total sq.ft of Building = 25,650**

Example Showing a basic idea of dividing the second flood gallery into the perimeter zone, interior zone, and core zone.



5 different building schemes

1. Resultant amounts of lighting power,lighting equipment, & lighting energy 2. Resulting air conditioning load that comes from light fixtures assuming all are on 3. Balance point temperature(BPT) for building schemes 4. Corresponding Watts/ sq.ft 5. Heat gain through the skin 6. Internal Loads the same for all 25 schemes
