5 Planning of Activity Space

• One basketball court is on the East and the other one on

the West, both are orientated along North-south axis to minimize glare effect.

• Children Play Areas are planned on the East, as most

kids play in the afternoon.

• Community Lawn Area are Community Farm planned on

the West, as plants enjoy strong sunshine.

• Entrance Plaza and Courtyard are planned in the middle

where community activities are always under shade most of the day.

• The courtyard & plaza are cleverly created by linking up the

covered walkway and the shopping verandah.

• It brings breeze (wind speed of 3.8m/s)
• It brings a sense of arrival
• It brings an identity to the estate

Courtyard design not only brings breeze effectively, it also enhances air movement downstream helping the dispersal of pollutant from buses by natural means. 8 Roof cover design allows natural ventilation, penetration of natural lighting and provides shelter in wet weather

• ff noise impact to sensitive receivers.

The solid and transparent roof pieces are cl cleverly tilted at an angle, and each them is not more than 230m2, such that

• No installation of mechanical

ventilation system is required.

• No installation of sprinkler system
• r any other fire services system is

required.

• No artificial lighting is required in

the day time.

• No energy is required for the
• peration of the PTI (except for

lighting at night).

The cover also kick noise for future development . Upon completion, noise performance was verified by on-site measurement and the result was satisfactory

• 80% of the carpark perimeter wall is open parapet, allows for

natural cross ventilation which is sufficient to remove pollutant, without any mechanical means.

• 8 Nos. of Solar tubes are installed at soffit of carpark to bring in

natural sunlight. Photo sensors to control operation of artificial lightings are provided. 30% of the parking spaces are equipped with elec. charging facilities , conduit is allowed for 100% elec. charging parking space in the future

Building Contracts are specified and implemented with the following environmental initiatives:

• Specifying requirements for environmental

management plan and monitoring requirements for air, noise, water pollution during construction (SA 10, SA 11, SA 12, SA 13).

• Specifying requirements for waste management

plan (MA P3, MA 10, MA11)

• Not using virgin forest product for temporary

works during construction (MA P1).

• Using timber from sustainable source for

permanent works (MA 6).

• Specifying requirements for water quality (WU

P1).

• Using Water Efficiency Labelling Scheme water

efficient shower head (Grade 1) and mixers (Grade 2) to achieve water saving of 20% (WU P2, WU 1).

• Using WC suite of 6 lit. to achieve reduction in

annual sewage volumes by 20% (WU 6).
