Expertspeak: Manjul Trehan, Country Manager India, LutronWhat kind of lighting solutions  can people adopt in residential and commercial spaces to ensure reduced electricity consumption?

For entire buildings, sophisticated software can be used to configure, control, manage, monitor and report on all the lighting in a building from a central location.
By maximising the use of daylight to complement electric light, such technology, for instance Quantum, created by Lutron, can save up to 70 per cent of lighting energy consumption in a commercial building. In residential spaces, dimmers can be used to save energy for one or two circuits of lighting.  For commercial application, technology is available that ensures reliable wireless communication between a sensor and the switch, offering an energy saving solution ideal for retrofit installation.

How does your HomeWorks system work?
HomeWorks System provides integrated control of a home’s light switches, dimmers and electronic shades from wall-stations or hand-held remote controls regardless of home size. All shades, dimmers and switches in the system can be controlled individually or can operate together at the touch of a button according to preset scenes for different activities such as a party, movie or dinner. For example, lights can be turned on to 75 per cent brightness in the living room, 65 per cent in the kitchen and 50 per cent in the dining room, while turning lights off in areas like the master bedroom or other rooms without any activities going on, by simply pressing designated buttons on keypads and remote controls.

How can lighting security be provided in residential and commercial spaces?
A system can be incorporated at home, which can be integrated with the security and fire systems. Lutron, for instance, has developed products where systems can light up an escape path in case of fire. If there is an intrusion into your premise, these systems can turn all interior lights on and flash all exterior lights to alert people outside.  If you need to vacate your premises for a long period of time, you can preset your lighting to replay your normal and everyday lighting patterns to simulate an occupied mode.

Which products or lighting equipment can save on energy. How much?
Dimming lights actually help to reduce heat in the space, which decreases the power use of your AC system. Typically every three-watt reduction in lighting power eliminates one watt of cooling power. Lighting control systems are available with built-in clock can turn off or dim lights per schedule at certain times of the day or in relation to sunset and sunrise time. Typically, 15 per cent lighting energy can be saved this way. Also if people use occupancy sensors, which turn off lights when people vacate the space, they can save up to 60 per cent energy, depending on application and use. Good quality dimmers, like those by Lutron, are also good for the environment. They save energy and extend the life of halogen and incandescent bulbs. Longer-lasting bulbs mean fewer are going into landfills, significantly reducing our waste stream.

How does one control natural light?
To control natural light, people will either use manual shades or motorised shades. The problem with manual shades is that people tend to leave it either close or open all the time regardless of the amount of sunlight outside.

People are too lazy to adjust the window shades and some shades are just simply too heavy or inconvenient for adjustment, especially for those applied to huge and tall windows. On the contrary, motorised shades can give easy control with the touch of a button. Besides, it can be preset according to time schedule or even integrated with electric lighting control system to make best use of daylight to complement electric light.
