Building Design

    • Orientation
    • Building is North-South oriented - reduced solar radiation on longer facades.
    • Window
    • Double glass panes
    • Wall
    • Exterior Wall Assembly: 45 mm stone cladding, 40 mm PUF {For South-East wall 40 mm cavity}, 230 mm brick, 15 mm cement mortar. 1.56 W/sq.m.K (S-E) 0.45 W/sq.m.K (others)
    • Roof
    • Exterior Roof Assembly: 13mm broken china mosaic, 65mm brick, 50mm PUF (R-13), 9.5mm screed, waterproofing, and 203mm concrete slab on the interior. 0.36 W/sq.m.K
    • WWR
    • 19.84%
    • Daylighting

    • The use of internal courtyard allows diffused daylight into the building, avoiding unwanted glare and heat gain from incident sunlight.

    • Passive Cooling System

    • Radiant Cooling system is installed.

    • Sensors/Controls
      • Modulation of mixing valve installed on the common header radiant header
      • Controlling of re-circulating for radiant cooling system
    • Form
    • Rectangular
    • Shading

    • Shading devices are designed to allow daylight into space but do not allow solar heat gain through the glazed area.

      The external shading device framework and chajjas detached from the main structural system of the building to reduce the conduction of heat. The PV installation on the roof also acts as a shade for the roof itself reducing heat gain from the southern sun.

Building Performance

    • Renewables
      • Solar photovoltaic installation is 35 kW
    • Data Sources (measurement)
      • Slab temperature monitoring
      • Room temperature sensor
      • Room humidity sensor
      • Common header temperature in radiant piping system
    • Embodied Carbon Footprint

    • 30% reduction in CO2 emissions compared to the kind of buildings that are generally prevalent today.
