Flow chart for light planning

1. Analysis of the planning objective

  • Define the activities and different visual work that may be performed in the premises at different times of the day.
  • Define the lighting demands with regard to safety, visual needs and the visual experience.
  • Examine the need for emergency lighting. Define the aims for energy consumption, environment and maintenance of the lighting installation.

2. Analysis of planning conditions

  • Define applicable provisions, standards, recommendations as well as special demands from the client and users.
  • Define the conditions for lighting the room, the type of workplace and its working area, etc.
  • Investigate the conditions for the premises’ design, furnishings, type of monitors, flexibility, daylight and the character of the premises.
  • Establish the economic prerequisites for the installation and the maintenance conditions for the lighting installation.

3. Overall planning

  • Investigate the conditions for interaction between electric light and natural daylight. Check the possibility of daylight screening.
  • Investigate which light sources, luminaires and lighting systems best satisfy the demands aims and conditions.
  • Investigate the possibilities for lighting control to increase comfort and improve energy usage.
  • Investigate the overall co-ordination with other installations, colour setting and furnishings.

4. Detailed planning

  • Evaluate the different lighting systems; technically, visually and economically.
  • Establish the lighting system’s optimal maintenance factors taking the maintenance conditions into consideration.
  • Make a financial evaluation by calculating the life cycle costs based on the investment, operation and maintenance.
  • Compare the selected lighting systems with regard to other installations, colour setting, furnishings and the chosen equipment.

5. Documentation

  • Should be prepared as shown to the right with supplements according to the client’s wishes.
  • Include Installation drawings, control and assembly instructions as well as associated lists of light sources and luminaires.
  • Lighting calculations and visualisations that verify under which conditions the system operates to the specified demands.
  • Present calculation prerequisites and the lighting system’s maintenance plan (see instructions in the Lighting template).
