Greenery
• Review the possibility of introducing plants to the external area of the shop space
where the shop space is rented together with an adjacent exterior open area:
- Review the possibility of introducing trees into the exterior open area or the
possibility of preserving the existing good and healthy trees to help provide
shade to the adjacent shop space, to reduce heat gain by the shop interiors,
and to save on energy consumption for air-conditioning.
- As exterior planting can reduce the heat island effect and mitigates noise and
air pollution in general, this will help make the exterior area more pleasant
for customers to enjoy, which is beneficial for the outdoor seating areas of
restaurants and cafés.
• Review the possibility of introducing interior plants which can help to provide
a healthy indoor environment. Choose plants that help to reduce pollution and
increase oxygen supply.
• Review the possibility of introducing a
.
• Meet the green goal of greening ratio.
• Allow space for sustainable tree planting.
• Allow structural loading for skyrise greenery.
Energy
• Consider a passive design 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. Check with the landlord
to see if windows can be relocated to provide the most suitable orientation to
reduce solar heat gain and glare.
2) Check with the landlord to see if it is possible to introduce windows, louvers
and doors that can be opened in the direction of the
to enhance
natural ventilation and reduce reliance on air-conditioning.
3) Where possible, use interior finishing materials that are light coloured and which
will help reflect heat instead of absorb heat. Similarly, dark colour materials will
generally absorb more heat than light colour materials.
4) Minimise the use of internal finishing materials that will absorb and retain heat,
such as carpets, where possible so as to avoid the heat being retained within
the building and increase the need for air-conditioning.
Note:
Passive design is the design of the shop space 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.
• Review the need to comply with the Building Energy Code and the need for an
• Use energy efficient equipment.
• Consider heat recovery, which captures waste heat for re-use
(e.g. waste heat from the air-conditioning system may be used to heat water).
• Consider using Energy Label Grade 1 air-conditioning units.
