Methods of lighting control and a model for estimating energy savings of artificial lighting is developed. It estimates hour by hour energy consumption of lighting and accounts for building orientation, direct sunlight penetration, external obstructions and shading devices. The model could serve as a useful aid to building design, but it does not establish the affects of decisions about daylighting on other building environmental factors.pdfen-NZhttps://www.wgtn.ac.nz/library/about-us/policies-and-strategies/copyright-for-the-researcharchiveEnergy conservationLightingArchitecture and energy conservationTextAll rights, except those explicitly waived, are held by the Author
