Tuesday, January 24

Times Topics
9.30 Welcome, class introduction, design project (teams formed on following morning)
10.00 General introduction to daylighting (benefits, design issues, thermal aspects, built examples)
10.30 Introduction to building simulation (why simulations for architects, tools used in this course)

Photometry (definition, measurement, typical values, DF definition)

Static daylighting metrics (context of LEED, selected results from NRC survey, DF and solar shading)

Daylight factor calculations: Sky models CIE and Perez, split-flux method, LEED spreadsheet method

Daylight factor simulation: Design sky, split flux method in Ecotect

  • Hands-on exercise: DF calculation in Ecotect (split flux)
  • Hands-on exercise: solar shading module in Ecotect

Introduction to Radiance

  • Hands-on exercise: Radiance visualizations
  • Hands-on exercise: DF calculation in Ecotect (Radiance)

Climate data (Data definition and measurement, energy and weather data directory)

  • Hands-on exercise: Weather tool in Ecotect

Overview on visual comfort (glare, contrast, recommendations)

Dynamic metrics and related tools


Hands-on exercise: Daysim exercise from tutorial interrupted by discussions on:

  • Short time steps dynamics
  • Daylight coefficients
  • User behavior model
  • Daylight autonomy results
17.00 Hands-on exercise: Students to repeat DF, solar shading and daylight aautonomy analyses on their own
17:30 End of first day
