Stage 2: Design stage
Existing building – reuse and enhancement
• Review the possibility of using the existing building structure, including the existing
foundation, structural columns, walls, beams, floor slabs and roof structure which
will help reduce demolition waste and save costs in redevelopment of the existing
building into a new shopping mall, as well as reducing the
.
• Review the possibility of re-using existing materials, finishes, decoration and
furniture which will reduce demolition waste and save costs in redevelopment of the
existing building into a new shopping mall as well as reduce the
.
• Review the condition and efficiency of existing building services systems and
installations, and plan replacements with more efficient systems for more savings
on energy use and water use.
• Review transportation, connectivity and parking in respect of the existing building:
1) Review the possibility of designing a new covered walkway or bridge connection
to any nearby public transportation system such as the Mass Transit Railway or
a bus terminus.
2) Review the possibility of providing shuttle bus services to the shopping mall
where public transportation is not nearby.
Note:
Convenient public transportation will reduce trips by private vehicles, thus
reducing traffic congestion problems at the mall as well as associated customer
frustration.
3) Review the possibility of the following upgrading of parking for customers:
- Provide parking spaces for electric vehicles as well as a charging facility for
electric vehicles.
- Provide a smart parking system to eliminate unnecessary driving of cars in the
carpark while looking for empty parking spaces.
Electric vehicles are more environmentally friendly.
Compared to vehicles that depend on fossil fuel, electric vehicles are more energy
efficient and will cause less air pollution.
• Review the possibility of preserving the existing vegetation conditions for
maximising preservation of trees on the site.
• Allow proper tree protection measures for the preserved trees on site.
Natural ventilation vs. mechanical ventilation
and air-conditioning
• Considerations for natural ventilation:
1) Review the functional and commercial needs of the shopping malls and shop spaces.
2) Identify opportunities for introducing natural ventilation or hybrid ventilation to the
existing building to reduce energy use and energy cost.
• Where air-conditioning is used:
1) Review the possibility of replacing the existing air-conditioning system with a
more energy efficient air-conditioning system (e.g. water-cooled system for
central air-conditioning).
2) Consider adopting the Hong Kong Energy Saving Charter. The commitment of
both the landlord and the tenants is important.
3) Individual tenants’ sub-metering of air-conditioning usage should be implemented
where it is possible to encourage a tenant’s positive support for reducing energy use.
