Effective façades can help to reduce the heating and cooling loads of buildings, leading to energy savings. YKK AP’s engineering technologies enable it to develop façade systems along environmental principles which incorporate shading, insulation, natural ventilation and daylighting features. The systems help to save energy while delivering comfort by optimising the interior environment and minimising energy consumption.
The company’s environmentally-friendly façades are developed firstly through computer generated simulation and engineering calculations, followed by verification during laboratory testing, and finally through on-site recording of actual results. Some of the façades being studied include:
The most common façade system, this is used as the basis of technical comparison with other systems. Blinds are located on the interior. The heat from solar gain is absorbed, reflected by the blinds on the interior and radiated into the room.
Blinds are located on the exterior. The solar heat is absorbed and reflected by the blinds on the exterior and radiated externally.
This type uses double-layered glass with blinds between the layers where air passes from the interior room through the cavity by mechanical ventilation. The solar heat absorbed by the blinds is removed by mechanical ventilation. Solar shading property is high. Thermal insulation property is higher than double-pane glass, due to the air flow in the cavity between the panes (varies with the air flow rate).
This type uses double-layered glass with blinds between the layers where air passes from the exterior through the cavity by stack effect. The solar heat absorbed by the blinds is removed by ventilation. Solar shading property is high. Thermal insulation property is higher than double-pane glass.
With its engineering know-how, technology and facilities, YKK AP dedicates itself to innovating and coming up with better façades for the future.
