Building Design

• • Orientation
  • The longer axis of the building is oriented on the East-West axis in order to reduce solar heat gain
• • Window
  • Split window with daylight panel (upper glass) and vision panel (lower glass)
• • Wall
  • Light shelves in wood panels topped with white reflectors to protect occupants from direct light
• • Roof
  • Light colored ceilings reflect light and reduce the contrast in brightness
• • WWR
  • Less than 38%
• • Daylighting

  • 78.54% of living areas / Daylight hour energy savings: 158 kWh

• • Artificial Lighting System

  • Reduced with light shelves, floor planes and reduced WWR

• • Active Cooling System

  • Conventional Cooling/ Effeciency: 0.6 KW/TR Radiant Cooling / Effeciency: 0.45 KW/TR Energy consumption for Conventional Cooling: 440000 units/ Radiant Cooling: 269000 units Energy Index for Conventional Cooling: 38.7 kWH/sqm, Radiant Cooling: 25.7 kWH/sqm Radiant Cooling consumes 30% less energy than conventional cooling
