Passive Climate Design Research

Work Presented by :Aditi PadhiGraduate Research Assistant

Case Study – Parekh House- Charles Correa

• LOCATION: AHMEDABAD, 1967-68• ELEVATION : 53 m• LATITUDE : 23 04N LONGITUDE : 72 38E• Two pyramidal sections from housing types developed for Cablenagar• Summer section – to be used during daytime; protects interior from heat• Winter section – to be used in early mornings and evenings; opens up the

terraces to the sky• Since site faces east-west, house consists of 3 bays• Summer section sandwiched between winter section and service bay (for

circulation, kitchen and toilets)• Bearing walls made brick .Design concept:• cubical composition• arrangement of spaces as per their time of use.

Passive features• A void is provided• Louvers• Level differences

How sun effects the design…?• Sun path : N-E to N-W• Exposure of east and west façade to the sun.• Hence the design came…the three block system..• Over head pargolas-helps in shading the wall during the day time.• Recessed or Sunken windows-allows only diffused light into the building.• Louvered doors-it also cuts off the heat and direct sun coming from the

entrance.• STEP PYRAMIDAL form of spaces inversing with respect to the season.• Garden space in front of the house.• Material chosen-concrete and brick covering.• Good climatic responsive building since 37 years of its construction

Case Study – Shodan House- Le Corbusier

• LOCATION: AHMEDABAD, 1956• LATITUDE : 23 04N LONGITUDE : 72 38E• structural simplicity,• Plasticity in the handling of the rooms—in their form, their dimensions, in the

shadows of the brise-soleiol on the facades and of the roof parasol�• the ingenuity of the Villa Savoye of 1929-1930 at Poissy, placed here in a tropical

and Indian settingSince site faces east-west, house consists of 3 bays• De Stijl design choices are controlled well within the building by the classical cube. • the interior concrete piers, running to the full height of the building’s elevation, is

based around the architect's domino skeleton design

Design concept:• Corbusier’s Regionalism in a tropical setting• arrangement of spaces as per their time of use.Passive features• The terrace plays an important role in the natural climate control process, cooling

down the bedrooms in the middle of the day and providing an alternate sleeping area during the summertime.

• The roof also features an oval aperture, which matches up with a hole in the lower slab roof, giving visitors a framed view of the sky. This is almost mimicked by the pool, situated at the base of the ramp, aiming to bring the outside in

• The rectangles on the north-west and south-west façades are further emphasized through the installation of brise soleil for protection from glare.
