5.2.2 Maintenance and alterations
During maintenance and alterations in shopping malls, draining off and re-filling the water in the system is necessary.
However, the process may consume significant amounts of water. Instead of wasting water, it is recommended that the
water collected during maintenance and alterations should be recycled whenever possible.
5.2.3 Professional help
It is important to engage professionals for detailed consultation on the implementation of fire services at shopping malls
and shops. The following is a list of references for obtaining professional help:
• Authorised persons (AP) – Appendix A (2)
• Registered professional engineers (RPE) in the building services discipline – Appendix A (4)

Fire services
The fire services system is designed for the purpose of protecting life, and the energy and green design element is
traditionally not a concern of the designer. However, there are still some discretionary issues which can contribute to
green design.
5.2.1 Zero ozone depletion fire suppression agents
For some potential fire hazards, such as fuel tank rooms and server rooms, gas flooding
fire extinguishing systems may occasionally be encountered in shopping malls. The gas
used for flooding is usually a halocarbon compound, but not all of them are produced with
zero
(ODP). To contribute to the environment, zero ODP fire
suppression agents should be selected.
