  17. 17. Zoning  Lv 1The transition of spaces from the Public spaces: through the mainentrance into the buffer spaces, to the semi-Private spaces like theliving hall to upstairs into the kitchen and dining area to the Privateareas.
  18. 18. Zoning  Lv 111On a more vertical approach, the ground floor is a cluster of public,social and semi private spaces, whereas the first floor is totally dedicatedto private spaces

  20. 20. BUILDING MATERIALS Locally available bricks of clay are used for the walls. Lime plaster is used as binding material. Athangudi tiles are used for the flooring. Iron beams are used to support the flat roof. Wooden window frames and shutters are used which open inside the house. Wooden louvers are used to obstruct the direct entry of sunlight. Iron beams are used to secure the openings of the windows. Railings are made out of brass.
  21. 21. Climatic Data SUMMER - 30 C TO 35 C DURING DAY AND 25 C TO 30 C IN THE NIGHT WINTER - 25 C TO30 C DURING DAY AND 20 C - 25 C IN THE NIGHT Kolkata India Average Yearly Precipitation Kolkata India Average Annual Temperatures 1400 mm PER YEAR. MAJORITY RAINFALL - MID JUNE TO MID OCTOBER, WHICH IS OBTAINED FROM SOUTHWEST MONSOON WINDS. Relative humidity: humidity is generally Kolkata India Average Monthly Sunshine Hours very high, about 70 – 90 % throughout the year.
  22. 22. Climatic Response The balconies on the east side and the presence (initially) of tall trees and abundant plantation reduced heat gain. Permanent ventilation with the help of ventilators on east and west side at the height of 3700mm from the floor level provides the supply of fresh air even when the doors and windows have to be kept closed. Ventilation is done by placing two windows and two doors in front of each other at the room level. Stack Ventilation
  23. 23. Climatic Response Since the house is L shaped oriented along east direction it provides minimal heat radiation gain The orientation of the building is such that it provides shading to the internal faces of the house resulting in reduction of heat gain. The number of fenestrations including the permanent fenestrations(jalis) induce cooling through evaporation E W
  24. 24. Climatic Response Balconies running both around the ground and the first floor actsas buffer-spaces, which moderates the outside extremities ofclimate.Each balcony has a mild slope towards a corner with theplacement of an opening leading to an extended pipe whichhelps rainwater to flow out .Also the balconies can be washedeasily since water flows out.
  25. 25. Climatic Response  The pale colouration of the walls increases surface- reflectivity and reduces input thermal coefficient.  13000 mm high Jackfruit tree with its foliage provides shade throughout the day.
  26. 26. Construction DetailsPaneled doors Paneled timber and glass Windows with timber louvers on the outside Louvers restrict the entry of precipitation but allows the entry of daylight and fresh air supply
