Daylighting Pattern Guide
The Daylighting Pattern Guide is a no-cost, interactive design tool that uses a combination of real-world built examples and advanced simulation to set the stage for substantial reductions in lighting power consumption and overall building energy use. It was developed through a partnership between New Buildings Institute (NBI), the University of Idaho and the University of Washington.
High quality daylighting design has the potential to increase user satisfaction and productivity and save substantial energy. However, successfully designing daylighting that supports both comfort and energy savings can be a complex and challenging process.
The Daylighting Pattern Guide presents 19 prime examples of well-designed daylit spaces around the United States. Each project was photographed, physically measured and simulated using the Radiance simulation tool. Sensitivity analysis of key design variables was conducted on each project to demonstrate whether the outcome was optimized and to illustrate the impact of multiple ‘alternate design decisions’ on the daylighting performance.
Key daylight patterns, or variables including orientation, glazing layout, area, shading strategies, furniture layout and ceiling height that contribute to the success or failure of a daylighting design, were also identified. This information allows users to differentiate between good built examples of daylit space, the information generated by design analysis tools and the ‘rule of thumb’ guidelines that designers commonly apply.
Project types included in analysis are offices, schools, libraries, laboratories, museums, industrial facilities and recreational facilities across a diverse set of regional climates.
