Sustainable Design and Construction: Architectural Planning
Architectural Planning
Connectivity with Community • Accessible from all directions and well-
connected.
• Provided with public transport, basic services and recreational facilities in vicinity.
Architectural Planning
Maximized Landscape • Maximized green area about 1982 m2
(> 30% of site area).
• Quantity and variety of plant species enhanced from pre-development. Compensated trees and add shrubs and groundcovers.

Architectural Planning
Urban Ventilation Conducted wind tunnel test to ensure : • proposed development will result in
favorable air ventilation conditions when considering that the existing conditions were measured on an exposed and open site.
• The ratio between existing and proposed wind speeds did not exceed the threshold factor of 2
• The mass of the building includes large, broad facades which encourage the downwashing of strong winds from higher elevations to grade level, and therefore enhances air ventilation through flow mixing and recirculation.
Architectural Planning
Daylight Access • Adequate setback from neighboring
buildings was planned.
• All neighboring assessed facades could achieve more than 12% VDF. The current design shall not block daylight to access the neighborhood.
• The maximized vision glazing allows abundant daylight access to retail and office floors (average DF > 2%).
Architectural Planning
Building Orientation and Built Form • larger façade facing south and north while smaller
façade facing east and west. The purpose is to reduce heat gain of afternoon glare from the west.
• 4/F – 20/F set back under 21/F – 23/F on east and west elevation. The set back provides shading effects on east and west facades for most of the office floors.
Architectural Planning
Light Pollution Dimmable Device • There are more than 80% façade lights shall be
equipped with dimmer and to be controlled by BMS.
• During normal operation days (non public holidays), the dimmable lights shall only be operating at 50% of capable lumen to reduce light pollution.
Operational Control • Some façade lights shall only be installed as
stand-by to create festival lighting effect.
• During normal operation days (non public holidays), some façade lights on shall be programmed to be turned off to reduce unnecessary light pollution.
