  • 17. By reducing lighting loads & Energy Conservation other heat generators the building energy load can be reduced by More than 60% IES Lighting Average wattage / s.f. = 2 watts / s.f. Goal energy wattage ≤ 1.3 watts / s.f. 10% 5% 15% Lighting load example: Existing = 150,000 s.f. New = 150,000 s.f. 300,000 s.f. 30% 40% x 2 watts 600,000 watts x 3.41 BTU/w 2,046,000 BTU ÷ 12,000 BTU/ton Lighting = 170.5 tons AC Goal for lighting load: Reduce load to 1 watt / s.f. = 170.5÷2= 85.25 tons Target Goal = .5 watts / s.f CRI Think Tank Charrette #2 Designing the Center for Community Renewal Energy, Green Systems & Learning Environs 10.29.08 October 17-18, 2008
  • 18. Lighting Strategies A. Better Lights : CFL, LED, Fiber Optic B. Glare free Lighting : Task, Ambient lighting C. Brightness Ratios : 70% walls, 80% ceilings, 50% work surface, 20% floors D. Lighting Controls : Education, timers, sensors, photocell E. Day lighting : Goal = .5 watts per square foot Day Lighting Goal : Daylight factor for Louisiana sky vault = (1000 FL )(2%) = 20 FC Strategies : General Spaces / rooms 2% Conference / Office 5% Atrium / Lobby / Public Areas 8% Example: (85 tons)(≥ 20% goal for day lighting) = 17 tons 85 tons – 17 tons reduced from daylight = 68 tons for lighting (60% improvement from 170.5 tons per IES 2 watts / s.f.)
