1-5 Ventilation in Carparks
Encourage the use of energy efficient design and control of ventilation systems in carparks.
(a) Carparks designed with natural ventilation.

(b) CO sensors are used to regulate the demand for mechanical ventilation (MV).
There are two types of CO sensors which are
- SOLID STATE SENSORS (METAL OXIDE SEMICONDUCTORS)
- It is sensitive to a wide variety of gases but can be tuned to have preference for certain gases
- The accuracy of measurement of these devices can be significantly affected by changes in temperature and humidity
- Long life span of 2 to 10 years
- ELECTROCHEMICAL SENSORS
- High accuracy
- Low power requirement
Encourage the use of lifts with the following energy efficient features :
(a)AC variable voltage and variable frequency (VVVF) motor drive or equivalent.
(b) Sleep mode features or equivalent.
- lift can be programmed to hibernate after a determined amount of time.
- Use LED light or fluorescent lamp
(c)MRL (machine room-less)
- A gearless lift uses up to 50% less energy than traction drive and 70% less energy than a hydraulic drive
