- In many cases you can use lower wattage bulbs and get same amount of light. Look for lumens on the bulb (CFL) & not for watts. Lumen indicates the brightness while power indicates eenrgy required to illuminate the area.
- Always plan bulb location in such a way that the light is not hindered by any other room fixture.
- White light is more comfortable than any other light for reading & day to day use. So should consider it in studies, drawing room etc. Other types can be considered for infrequently used areas e.g. toilet, bathroom etc.
- Install photoelectric controls for outdoor lighting.
- Choose light colors in the rooms for better reflection, becasue dark colors absorb light & need more wattage for same illumination.
- Use good quality reflector & you can save lot of energy due to higher reflection. This can bring it down by ~33% if designed properly i.e. selection of reflector, selection of bulb, location etc.
- Use dimmer controls for reducing energy consumption whenever possible.
- Try to locate AC unit on the north side of house to avoid direct sunlight.
- Use sun screens on window glasses to avoid radiation heat.
- AC thermostat setting should be ~24°C which is reasonably good & comfortable temperature everywhere.
- Use low wattage lighting in the rooms to avoid unnecessary load on AC.
