Greenery
• Review the possibility of introducing plants to the external areas of the existing
building of the shopping malls:
- Trees can provide shade to the buildings and pedestrians.
- Exterior planting can reduce the heat island effect.
- Greenery also mitigates noise and air pollution in general.
• Review the possibility of introducing a
to the existing building of the
shopping mall – this reduces the heat island effect, the heat load and energy
consumption for air-conditioning.
• Review the possibility of introducing interior plants to help provide a healthy indoor
environment. Choose plants that help reduce pollution and increase oxygen supply.
• Review the possibility of introducing a

• Maintaining existing vegetation and tree preservation for the merits of instant green
coverage of the development.
• Where unhealthy plants are incompatible to new development, removal and
replacement planting are advisable.
Energy
• Review the possibility of introducing passive design features which will reduce
energy use and energy costs with less expenditure on equipment. The following
are some simple examples of passive design that can be considered for an existing
building:
1) Reviewing the existing location of windows and check whether these have the
right orientation to minimise solar heat gain and glare. Relocate windows to the
most suitable orientation to reduce solar heat gain and glare.
2) Introducing windows, louvers and doors that can be opened in the direction of
the
to enhance natural ventilation and reduce reliance on air-
conditioning.
3) Checking skylight glass orientation to review whether it is correctly oriented to
minimise solar heat gain and glare. Modify the skylights if necessary to reduce
solar heat gain and glare.
Note:
Passive design is the design of the building that optimises the use of the
environment such as the use of natural lighting and natural ventilation which reduce
the energy use by artificial lighting, mechanical ventilation and air-conditioning.
