daylight simulation

Studies have shown that the health and productivity of building occupants increases when significant amounts of natural daylight are provided to occupied spaces and views to the outdoors can reduce stress and eyestrain issues. Additionally the integration of natural daylight sources, daylight sensors on light fixtures, and occupancy sensors can reduce lighting power use, and ultimatly reduce energy bills.

Prairie uses daylight simulations to guide design decisions with the goal of optimizing the introduction of daylight into spaces. Simulation allows us to evaluate building orientation, window area, as well as various glazing properties and shading strategies. With the information we gather, we are able to reduce glare, set goals for reduced lighting power density, and control passive solar gains. LEED 2009 has made modelling the preferred method of documentation for achievement of LEED credit IEQc8.1.  In addition, a daylight model can provide feedback to the building designers to enhance the quality of spaces for building occupants.  As with energy modelling, Prairie offers this service to those looking for input throughout the design process to help shape the project as well as those looking for documentation for the LEED credit.
