Lighting sector is often sighted as one of the low hanging fruit of energy efficiency, as it can be both retrofitted easily and also provides an option to chose from the most efficient technologies irrespective of climate and building type, especially for general indoor lighting. Improvements in lighting can be therefore done by choosing or replacing existing low efficient lamp technologies by most efficient ones and by assigning appropriate lighting controls. However, as explained in the above section, a holistic lighting design is also very important to supplement efficient lighting technologies.
