Controls Overview

Introduction to Lighting Quality Issues Related to Daylight Harvesting and Controls
  • Adaptation level
  • Distraction / naturalness / integration of sources (daylight and electric)
  • Perceived flicker at low dim levels
  • Link to other literature, like ALG-Online, Commercial Lighting Solutions, CHPS


Introduction to Electric Lighting and Issues of Integration with Controls
  • Lamps, ballasts, dimming, multilevel switching
  • Appropriate sources for each kind of control
- Dimming ballasts
- Flicker, Color shifts
- Instant re-strike
- Uninterruptable power source (UPS)
  • Link to other literature, like ALG-Online, Commercial Lighting Solutions, CHPS


General Introduction to Lighting Controls and Their Function
  • Daylight Harvesting
- Continuous dimming
- Multilevel switching
- Open loop
- Closed loop
  • Occupancy / vacancy sensing, different technologies, link to ALG-Online
  • Personal controls
  • Pre-set scene controls
  • Time based controls
  • Load-shedding


Analysis of Daylighting and Daylit Zone (Rules of Thumb and Simulations with Shading)
  • Window wall ratio (WWR)
  • Visible light transmittance (VLT)
  • Head height
  • Orientation
  • Daylit zone as per Std 90, 189, IGCC, Title 24


Placement of Luminaires (Electric lighting Design Principles)
  • Use pattern books of layouts. Choose those that integrate best with daylight, or demonstrate why parallel configuration works better than perpendicular.
  • Link to other literature, like ALG-Online, Commercial Lighting Solutions, CHPS


Introduction to Design Tools

  • Precalculated results – not real time
  • Modeling electric lighting in Radiance using IES
  • Exercise: Visualization of daylight and electric light (Radiance)
  • Placement of photo sensors, view of photosensors – Daysim, SPOT
  • Integration of photocell sensor: good idea or not? (sensor in luminaire or at the ceiling)
