lighting design requirements indoor in terms of energy conservation :
Install LED light fixtures for all ceiling- and wall-mounted fixtures that will be on for more than 2 hours each day, such as kitchen and living room, bathroom, hallway, and other locations.
Consider installing LED fixtures, rather than using LED replacement lamps in incandescent fixtures.
Use CFLs or LEDs in portable lighting fixtures that are operated for more than 2 hours a day..
Use occupancy sensors for automatically turning on and off your lights as needed.
outdoor :
