• Review the need to comply with the Building Energy Code and the need for an
.
• Use energy efficient equipment.
• Consider the use of a
for air conditioning.
• 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.
Water
• Water sampling, as described in
by the Water Supplies Department, can be carried out to ensure that the quality of
water that is delivered to the shopping mall users is acceptable.
Note:
Quality of water may be affected by the condition of the plumbing such as
rusty pipes.
• Water reduction measures to be considered – rainwater recycling and use of
where appropriate.
• Use of water efficient appliances and fittings.
Stage 3: Construction Stage
Construction waste, noise and pollution
• Minimise construction waste – reduce, recycle and reuse.
• Minimise construction noise –
1) Consider prefabrication to reduce the amount of on-site work.
2) Consider the time of construction outside the shopping malls and shop spaces.
3) Consider the use of construction methods and materials that minimise the
cause of pollution. Avoid use of products that contain:
-
- VOC
-
- Carpet and underlay that gives off gas
4) Provide a proper fresh air supply and screens to prevent pollutants affecting the
neighbours.
5) Provide proper ventilation in the construction area to provide a healthy working
environment for workers.
• Ensure proper tree protection for the preserved trees on site.
Note: How to encourage your contractor to be green:
• When you issue a tender, specify the green objectives of your project and ask the
tenderer to submit their job references for green building projects.
• In your tender specification, discuss with your consultants how to provide incentive
clauses for the contractor such as allowing the contractor to submit proposals for
cost saving alternatives that can reduce construction and demolition waste.
• During the construction stage, engage the consultant and contractor in
discussions to review construction methods that can reduce construction
noise and pollution. If possible, create an incentive structure that recognises
and rewards the contractor for achieving green targets set by you and your
consultants.
