Replace inefficient incandescent lamps with Light Emitting Diodes (LEDs) or Compact Fluorescent Lamps (CFLs). Switch off lights in unoccupied areas or after working hours. Decrease the lighting and brightness in portions of the building that do not need strong lighting. Ensure all lighting illumination follows that 2013 International Energy Conservation Code (IECC) recommendations for Abu Dhabi by the Department of Municipal Affairs and Transport. Table 505.5.2 "Interior Lighting Power Allowances" found on page 63 of the 2013 IECC for Abu Dhabi contains the full list of illumination recommendations. Conduct periodic maintenance on light fixtures, including cleaning and replacing bulbs and ballasts. Disconnect light ballasts immediately when the fixture has exceeded its use and replace the light fixture as soon as possible. When possible, use daylight through windows as a lighting mechanism instead of artificial light. Adjust workspace lighting, such as having an overhead light and/or a task light over your desk. Install occupancy and/or ambient light sensors. Allow each worker to control his or her individual lighting space and add lighting controls when necessary. Account for computer screen reflectivity and user comfort when adjusting light brightness. Areas occupied by multiple individuals (e.g., meeting rooms, hallways) should be considered for lighting needs, should only be lit when in use, and brightness should be adjusted according to the needs of the room. Multi-purpose rooms (e.g., conference rooms, auditoriums, or lecture rooms) should be adjusted for lighting on an individual basis to maximize efficiency (e.g., the light can be shut-off while the screen light is on for presentations, and then turned on when there is more user interaction). Outdoor lighting needs to be controlled similarly to indoor lighting, and illumination levels, type of lighting fixtures, and lighting controls should be considered. Outdoor lighting should be directed only where needed, glare should be minimal, and the illumination levels should be both appropriate and even.
