Because a designer neither sells nor installs lighting equipment, the design is based on an objective understanding of the project goals and budget. Lightning app builder pdf professional#Description Role of Professional Lighting DesignerĪ lighting designer brings knowledge and expertise of a quickly expanding array of available lighting equipment and technology. Contemporary electric lighting design captures this electricity savings opportunity while improving visibility in the built environment. Ironically, much of this commercial building occupancy takes place during daytime hours when daylight could provide for some or all of the lighting requirements without any electricity use at all. This represents about 22% of total commercial building electricity use in the United States. The Energy Information Administration estimates that electricity used for lighting in US commercial buildings totaled 297 billion kWh in 2010. The approach also represents an enormous business opportunity in the form of energy savings in new and retrofit construction. Recognizing perhaps what John Tyndall observed over 150 years ago, the relatively new lighting design profession takes a more refined approach to providing visibility for the occupants and enhancing architectural forms rather than flooding a space with light. Lighting control was unnecessary as illuminated (but empty) buildings defined the nighttime city skylines. A philosophy of, "More light, better sight" summarized the approach to architectural lighting. Despite this observation, cheap and abundant electricity led to lighting design in the mid twentieth century that meant little more than sizing branch circuits large enough to safely deliver power to the light bulbs. While observing lines of dirt and debris frozen in a glacier, the British physicist, John Tyndall noted in 1860 that more light on an object did not necessarily increase its visibility.
