Building Envelope
Application of double-glazing curtain wall system with special glass combined with sunshades is used in all the Buildings in Phase 1 aiming at reducing the overall thermal transfer value (OTTV) to 20 watts per sq. meter. The glass is chosen to have a low thermal conductance and a high solar reflection larger than 50% together with a high light transmission over 70%.
The facades of the buildings are clad with a combination of aluminum panels, double glazed window units and building integrated photovoltaic panels.
A second facade is added in front of the curtain wall on the facade facing west. The cavity in between the two facade has an upward passage air to carry away the solar heat absorbed. It also helps to shield traffic noise from Tolo Highway.
Clear glass is used throughout the facade to help to reduce the amount of glare that could affect motorists. The roof panels consist of two layers to stop heat from entering the buildings.
The roofs are clad with insulated metal roofing sheets covered with PV panels to provide shading to the main roof and offices below.
The double-glazed curtain wall system, sun shading devices together with the metal roof help enhancing the building's thermal and acoustic performance.
