3.0 CASE STUDY

3.1 LIVE CASE STUDY – 1 HOUSE AT AMEERABAD

SITE AREA: 175 sq.m LOCATION: Ameerabad, North Karnataka

The home has a rectangle design that runs east-west, with the entrance facing east. The dwellings are designed to be compact, limiting gain and loss of heat. A little plantation area surrounds building. Interior verandah, which serves as the building's main circulation spine, acts as a buffer space, diffusing and distributing light and air from the courtyard within the structure. To prevent moisture from coming from the ground, high plinths are constructed. The 300mm thick walls impede heat transfer into the house, which is otherwise unnecessary for structural strength. The almost 3000mm high ceiling and 300mm thick roof significantly increase the time lag between heat conduction.

All local materials are used, such as black stone and mud as plaster for walls, Thandur stone and rubble stone for floors, Mangalore tiles and metal roofing sheets for the external roof, and wood for the rafters, internal roof, and columns, to make the structure climate responsive.

Climatic Factors that are influencing in the architecture of building are - As the climate of Ameerabad in North Karnataka is hot and humid, to ensure comfort from high temperature the building has thick walls made of black stone and mud is used as plaster which acts as heat resistant material. Also the building has vegetation around where they would be little temperature reduction. Also as the humidity is high in this region Courtyards are effective in stack effect and large openings of the building make sure there is flow of cool air. The building has enough gap for the unrestricted air flow & ventilation. Semi-open spaces are also effective in reducing the high temperatures and humidity. The precipitation also is high in this area so the house has a pitched roof for rainfall and floor around courtyard is raised, so there is no dampness around it. Water drains through the courtyard during heavy rainfall. To reduce the impact of direct sun radiation the building has good insulating & reflective roofing material and white paint reflects the heat away. Less surface area of the building is exposed to the sun. As the building is long and narrow the air easily flows. Vegetation around the building brings the cool air into the building.
