Daylighting Analysis
Internal Lighting and Daylight Optimization Analysis – 3D Rendering
Installing new lighting technology in an effective manner can be challenging in many cases. Constructing 3D models and using manufacturer light distribution data allows designers to evaluate these new fixtures before they are recommended.
This image shows how light is distributed by daylighting only in order to optimize the required artificial lighting.
Internal Lighting Analysis – 3D False Colour Display
Displaying lighting analysis with a variety of visualization techniques can help to evaluate the effectiveness of light fixtures or daylighting measures.
This image is a false colour rendering for two installed Solatube fixtures. Natural light is providing upwards of 2000 lux in this space during the average summer day at 12:00pm.
Internal Lighting Optimization Analysis – 3D False Colour Display
Reducing energy consumption is important from an environmental as well as an operational perspective.
The analysis below was undertaken to determine the effectiveness of replacing electrical lighting fixtures with non electrical Solatube fixtures that bring natural light into an interior space. The areas in white are at desired lighting levels and demonstrate that half the artificial lighting can be replaced with daylighting fixtures.
Option 1:
All Electrical Lighting
Option 2:
Electrical and Solatube Lighting
The primary aim of natural lighting is to provide sufficient light under all circumstances for the tasks performed within a space. If such a lighting level cannot be achieved by natural light alone, then localized artificial task lighting can be used to supplement.
Site Daylight Analysis
With some forethought and innovative solutions, natural light can potentially provide more than enough light for most applications. However every building is different, and not all buildings require the same amount of lighting, either daylight or artificial. Good design requires that every building be evaluated for potential daylighting opportunities first and then artificial lighting strategies.
