(b) CO sensors are used to regulate the demand for mechanical ventilation (MV).

  • 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 – 2 to 10 years

1-7 Ventilation in Common Areas

Encourage the use of energy efficient design and control of ventilation systems in the following common areas:

(a) Toilets

(b) Staircases

(c) Corridors

(d) Lift lobbies

(e) Atriums

1-8 Lifts and Escalators

Encourage the use of efficient lifts and escalators.

(a) Lifts with the following energy efficient features:

1) AC variable voltage and variable frequency (VVVF) motor drive or equivalent.

2) Sleep mode features or equivalent.

  • lift can be programmed to hibernate after a determined amount of time.
  • Use LED light or fluorescent lamp

(b) MRL (machine room-less) A gearless lift uses up to 50% less energy than traction drive and 70% less energy than a hydraulic drive

(c) Escalators with energy efficient features such as motion sensors.

1-9 Energy Efficient Practices & Features

Encourage the use of energy efficient practices and features which are innovative and/or have positive environmental impact.

(a) Computation of energy consumption based on design load in the form of energy efficiency index (EEI).

(b) Use of energy efficient features:


  • Heat recovery system
  • Motion sensors for staircase half landing
  • Ductless fan for basement ventilation
  • Sun pipes
