Lighting simulation

We offer "virtual planning", a universal and yet customizable planning tool for checking and optimizing the energy efficiency of buildings. Simulation calculations provide a reliable basis for assessing all aspects of building quality: ergonomic, climatic, thermal, ecological and economic. In each case we discuss the results of simulation calculations with builders/facility owners, architects and facility users.

Daylight simulation

In any building, light-level control for visual comfort – like proper ventilation and temperature control – plays a major role in human comfort. Intensive daylight use is an excellent way to achieve visual comfort, and it also significantly enhances a building's overall energy efficiency. The daylight levels that would prevail in a structure's rooms and halls can be studied in advance via simulation. The following types of aspects can be determined and optimized:

  • Daily daylight duration and brightness levels
  • Assessment of possible glare (for example, on desktop monitors)
  • Daylight autonomy
  • Impacts of light-guiding measures
  • Visualization via photorealistic presentation

Simulation of shadowing

Shadowing simulation is an important tool for studying the impacts of direct sunlight on buildings. Studies in this area provide useful information in the following areas:

  • Sunlight's energy impacts on building facades
  • Assessment of sun-shading solutions
  • Shadowing caused by other structures and by the structure itself (self-shadowing)

Artificial light simulation

The most important aspects to consider in artificial light simulation include safety, ergonomics and cost-effectiveness. In addition, it is important to remember that effective use of light and shade can greatly enhance a building's or room's visual impact. Areas of transition between natural and artificial light are often of special interest. Careful planning is required to prevent discontinuities in brightness levels and to counteract any undesired shadowing of incident daylight.
