The project addressed the benefits of commercial building-design techniques that utilize daylighting as an interior illuminant. Climatological data are used to develop a daylighting/design analysis method leading to climate-responsive, energy-efficient, commercial buildings. The method that was developed is called the Lumen Day Method. The method uses a statistical summary of the daylight resource, in combination with daylight aperture characteristics, and electric lighting-control strategies, to determine the daylighting-system performance efficiency as well as the electric-lighting energy use. The simple method allows for reasonable architecture/engineering design decision making during the early phases of the building-design process, but requires the generation of a burdensome amount of data for each city.
