Why is Daylight Important?
  • Light and health
  • Research topics in daylighting (productivity, photobiology, luminous variability, biophilia)
  • Research Methods (laboratory science, case study/POE, statistical analysis)
  • Energy use

What is daylight?
  • Basic physics
  • Climate, weather
  • Primary sky conditions
  • Sky models
  • Weather data analysis
  • Architectural response to sky conditions
  • The challenge and beauty of variability

Lighting and Daylighting Criteria
  • Metrics for light (Luminance and Illuminance)
  • Daylighting criteria, visual comfort metrics (horizontal Illuminance ranges, daylight factor, daylight autonomy, UDI, DSP, etc.)
  • Daylight programming, synthesis (patterns of climate/sky condition/time of use/criteria)
  • Glare metrics
  • Curatorial standards and daylight
  • LEED
  • Challenges with current metrics
  • Energy performance (thermal and lighting power metrics)

Design Methodologies

First Principles
  • Site analysis
  • Building Orientation
  • Building Massing and Fenestration
  • Programming for daylight
- Space layout: correlating space function with daylight zone
- Interior obstructions: walls/partition type, height, and location
- Interior surfaces: reflectance, finish, and color
- Luminance strategies: transparency, vertical surface illumination

  • Rules of thumb
  • Inter-relationships of daylight, sunlight, views in sidelighting for visual comfort
- When are they aligned and when are they at cross-purposes?
  • Glazing technology
  • Solar shading design
  • Interior and exterior glare control design

  • Rules of thumb
  • Design strategies
  • Diffusion methods (scattering, refraction, reflection)
  • Lighting design strategies for toplighting
  • Toplighting in conjunction with sidelighting

View Design
  • View and Amenity
  • The Viewshed
  • Designing for View: Fenestration size, proportions, location and transmittance
