5. Internal Lighting

  • Internal lighting in all relevant areas of the building is designed to provide an illuminance (lux) level appropriate to the tasks undertaken, accounting for building user concentration and comfort levels. <br><br>This can be demonstrated through a lighting design strategy that provides illuminance levels in accordance with national best-practice lighting guides.

  • The uniformity of illuminance due to electric lighting is as per the recommendation in the approved local standard.

  • ii. Demonstration area lighting off and audience area lighting reduced to a low level (for the purpose of line slide projection, but allowing enough light for the audience to take notes)

  • iii. All lighting off (for the projection of tone slides, colour slides, and for the purposes of visual demonstrations or performances)
