- 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.
