Code of practice for air-conditioning and mechanical ventilation in buildings


This code provides general guidance in the design, construction, installation, testing and commissioning, operation and maintenance of air-conditioning and mechanical ventilation systems in all commercial, office, and institutional buildings except health care facilities. The purpose of this code is to establish minimum requirements in mechanical ventilation and air-conditioning engineering practice such that an acceptable indoor thermal environment can be attained in an energy efficient manner with general consideration for the indoor air quality (IAQ), and maintainability of the equipment.

This code does not cover the following:

- specific indoor air quality concerns for minimising potential health hazards. Users should refer to SS 554 for specific / more complete IAQ requirement guidelines.

- heating installations as the majority of mechanical ventilation and air-conditioning systems in Singapore do not require any form of heating.

- industrial ventilation in control of specific air contaminants inside the workplace as such requirements are separately covered by a different set of regulations.
