Install motion sensors and timers
In situations where a light is rarely used you may receive savings of more than 90 per cent by installing a motion sensor or timer.
Lights are often left on 24/7 in the common areas of apartment buildings. Leaving lights on unnecessarily wastes electricity, money, and human effort because they will reach the end of their lifespan sooner. This in turn means that your maintenance person is called upon more frequently to replace those lights.
Controlling lights with motion sensors or timers is an easy and inexpensive way to reduce the energy wasted by unnecessary lighting.
You can install motion sensors or timers for as little as $100 - $200 and reduce this energy waste. The installation of motion sensors and timers is becoming increasingly popular in common areas like fire stairs, laundries and underground car parks.
- Timers are typically available as electronic or pneumatic switches with programmable time delays ranging from one minute to several hours
- They can be stand-alone or installed as part of a whole building system with central control for programming
- Motion sensors are typically infra-red sensors
- They can be wall or ceiling mounted
- They are available for indoor or outdoor fittings
- They can be connected to single or multiple lights
- They can have a time adjustment ranging from a few seconds to several minutes
