1. Daylighting Design

2. Why it’s a good idea Current Cost of Energy Model Energy Codes Productivity & Daylight “Green Design going Mainstream” Market Differentiation for “Green” Firms

3. Governor Hull’s Executive Order

4. Human Performance Up 20% increase in student performance Up to 50% reduction in absenteeism Rate of recovery increased in hospitals Conclusion: We are not indoor animals!

5. Economic Performance Over 20 years, 94% of the cost of a building is in people Therefore a 1% gain in productivity is worth more than a 1% increase in sales 1% Gain in prod = $4/sf/year in an office building (more than energy costs) Reduce Maint and O&M costs

6. Environmental Performance 40% of energy used to heat & cool buildings An aggressive daylighting strategy can reduce electrical loads by 30%+ Reduce Use of Renewable Resources Thus, reduce a Myriad of Pollutants

7. How: #1 is an Integrated Design Approach Reallocation of Construction Dollars from mechanical systems to daylighting systems.

8. Fundamentals: High QUALITY footcandles. May mean a reduction in the amount of glass Use High Performance Glass Protect Glass (Ground is the light shelf) Control Luminance Ratios
