Design

The sail-like curvilinear south façade is both a reference to the roof profile of the nearby Hong Kong Culture Centre and a reflection of the programme within the tower.

The reduced floor plate of the uppermost and lowermost levels allows the optimum number of diners to enjoy the harbour views, while different sized office floors provide greater choice for both larger and smaller enterprises.

Glass Act

Low-E glass comprises a Low Emissivity coating – a microscopically thin layer of metal oxide coated on the internal surface of double glazed clear glass. It is increasingly specified for window glazing as an energy saving strategy in modern buildings.

Keeping Cool

As the sun’s rays hit the aluminum shading fins they are deflected onto the inclined ceilings of the office interior, maximizing lighting gain while avoiding direct glare.

The triple-layered glazed curtain wall system comprises an outer sandwich panel of Low-E clear glass and an inner single panel of glass. Return room air circulates within the ventilated cavity, warmer air being discharged higher up the building. Incident solar irradiance in the cavity is therefore expelled, keeping the façade cool.

Light and Shade

Automated blinds are sandwiched in 200mm gap between the Low-E glass layers and operate via remote sensors that detect the intensity of the sun’s rays. Operated by solar energy, the blades of the blinds are also computer controlled, reacting to the position of the sun as it sweeps across the facades and achieving shading coefficient values as low as 0.31.

Sun Trap

Photovoltaic (PV) technology involves the conversion sunlight into direct current electricity using photoelectric materials.

At One Peking, PV system were installed at the top of the southern exposure. Electricity generated is directly applied to the active façade system which operates the blinds via a sun sensor.

Historic Tree

The glazed upper lobby looks out to a bamboo grove embedded between the two buildings – new and old. Beyond the garden and laced through the bamboo stems are the preserved trees, the roots having forced their way through gaps in the old stone wall. The branches and leaves cast shadows on the facade of One Peking, creating a picture that’s quintessentially symbolic of Hong Kong.
