Building Design

• • Orientation
  • Solar Passive Complex has been developed In response to solar geometry i.e. minimizing solar heat gain in cold period.
• • Wall
  • The complex is a single envelope made up of its outer walls as double skin walls having 5 cm cavity in between. The cavity walls facing south and west are filled with further insulation material for efficient thermal effect.
• • Roof
  • ll the roofs have been insulated with double insulation system to avoid penetration of heat from the roof. The atrium is covered by a lightweight shell roofing of 10 cm of high - density EPS (extruded polystyrene) sandwiched between high - grade FRP (fibre - reinforced plastic) sheets and reinforced with steel; specifically angled to allow sun in winters and block in summers.
• • Daylighting

  • On the south western facade, dome shaped concrete structures have horizontal and vertical intersecting fins with glass fixed in the voids to allow natural light with reduced glare. These allow indirect light to enter the building in summers and direct sunshine in winters.

• • Passive Cooling System

  • The wind tower centrally placed coupled with solar chimneys on the domical structures for direct & indirect cooling and drafting of
    used air.

• • Form
  • The building form is a three-dimensional form developed in response to solar geometry, i.e. minimizing solar heat gain in the hot-dry period and maximizing solar heat gain in the cold period, the scale and form of the building on the two main roads of the intersection bears the character and scale of a office building, the building responds to the residential context on the south/south-east edges by gradually scaling down in mass and volume.
