What Houzz contributors are saying:
Accessibility should be provided for persons with disabilities, with wheelchair-accessible ramps, elevators and bathrooms.Note: Vernacular or regional architecture used local materials, local construction techniques and planning strategies that suited the climatic conditions of that particular region. One of the traditional vernacular elements was the internal courtyard, which ensured maximum air ventilation, plenty of natural light in the rooms and a comfortable indoor environment. Jalis were used in hot arid climates: when hot outdoor air blew in through the small, cone-shaped apertures, it was compressed by them, and then expanded indoors, cooling down the room within. The best part about vernacular Indian architecture is that the traditional strategies of building design form the basic concepts of green building design.Lessons From Vernacular Architecture That Apply Even Today
External sun-shading“External shading of the windows, roof and walls is the most popular way to prevent indoor heat gain. I particularly use louvres as an element of passive cooling, which is my architectural idiom and that of the city of Chandigarh,” says Sangeet Sharma.The fixed sun-shading options include deep balconies, recessed windows or a continuous overhang, just as in this example.Trees around the building are very effective in shading the walls. Plants should be grown in the internal courtyards, as they enable cooling by transpiration – the leaves release water vapour, reducing the temperature of the surrounding air.Adjustable shading options include venetian blinds, curtains, retractable awnings and manually adjustable louvres in windows.Find an architect in the Houzz directory to design a naturally cool home
1. Location: Jaunapur, New DelhiFirm: Kumar Moorthy & AssociatesThis home is a reflection of the owners’ cultural roots in Kerala, transported to the warm climes of Delhi, and their belief in sustainable living. A waterbody at the entrance and dense vegetation all around, is one’s introduction to the home’s connection with nature.
Chuttu verandah (passageway)In Kerala architecture, the poomukham is appended with an open passage. the chuttu verandah, which leads to either side of the house, usually surrounding it. This space was traditionally marked by lights that were suspended from the roof, hung at equal distance from each other.See these passageways from around the world
The design of this home uses elements that have been conceptually translocated from the warm, coastal and wet region of Kerala to the hot climate of Delhi. A careful selection of apt components has been made in the form of lofty internal volumes under pitched tiled roofs, deep surrounding verandahs as shading devices, courtyard-centric planning for cooling benefits and other such design interventions. The house was designed to optimise the benefits of the sun as well as the breeze to combat the heat of Delhi.
