Climatic Context, Energy & Water Efficiency:
As the location in Mawana town in the state of Uttar Pradesh had an extremely variable weather with dusty winds and very high and low temperatures, the building was planned looking intrinsically into protected courtyards; spaces which also provide a shaded area for various student's activities.

These courtyards have spill outs, sitting spaces, planting, water features and play sculptures, where each court contributes to the over al microclimate. The courtyards are proportioned to be shaded and due to temperature and corresponding pressure differences, the cooled air inside ventilates into the classrooms, whereas the hot air from the classroom Ventilates out from the ceiling flush ventilators. The Courtyards also work to bring in diffused light into the Classrooms, besides the reflected light coming from the building edge through the light shelves above the windows. Simultaneously, direct glare is sought to be avoided by means of recessing and shading the fenestratioins.

The building work was promoted by a non-profit trust with severe cost constraints on the building program. Therefore, the built form has been conceptualised using locally available strong materials, including the clay brick as an exposed material, without the need for plaster. The brick fashions the range of design options including walls, open arched niches for the windows and the perforated screens. The design uses local stone for hard-paving wherever required. Therefore, despite providing higher than normal 11'6" ceilings for a spatial and cooler indoors, and a larger window area, the overall costs have been curtailed.

Water usage in the project is Optimised with stormwater harvesting from the building roof, filtered and stored in tanks for floor-washing and horticulture usage. Even children can access this rainwater from its underground storage tank by a handpump. Stormwater is also planned later to be reutilised for toilet flushing requirements through storage into an upper storey tank. Soiledwater (toilet water) is also proposed to be cleansed using a simple DEWATS based plant filtering System.

When disputes between Nakarattars arose due to private misunderstanding, Nakaravitutis along with temples and Saivite monastries (matams), provided venues for extraordinary meetings of the Community to resolve disputes. These meetings Were held under the jurisdiction of a respected elder or elders in the Concerned Community and were called Panchayats - on the pan (Indian model) - although disputes were typically mediated or arbitrated by a single person. Besides Nagarathars from different places get together attemple festivities making their affiliation to the temples and the bonding to their Pangalis stronger. These Nagarathar pilgrims stay in the Viduthis by paying any minimal amount feasible to them, as Mahamai. The Viduthis hold an Undiyal (Hundi- money Collection box), in which the pilgrims deposit their Mahamais which is used for the running of the Viduthi. Spatial vocabulary of Nagaraviduthis in Chettinad: In the traditional context of Chettinadu, the edifice of Vidut...

The third zone is the service zone in the form of courtyard for cooking and Serving food. The toilets also are located here. Sometimes there are exclusive bhojana halls to serve food. The Central axis is how ever maintained and the planning is Symmetrical. Some Viduthis are divided into two, three or four divisions, paralleling each with their own central axis about which it is planned. These axes run parallel to each other starting at their respective entrance with well detailed main door flanked between the colonnaded thinnais on either side. The Illupakkudi Viduthi has two divisions, one for administrative functionalities and other for performing rituals. The soorakudi Viduthi and Pillayarpatti Karpaga Vinayagar Nagarathar Viduthi has exclusive bhojana halls. The Mathur Viduthi is the biggest of all. It has two divisions with a common wall between them. Both the halves are accessed from the main road. The western half, with more elaborate entrance is further divided into three...

The Vituti was directed by a board of trustees and employed a manager and staff to provide services for travelling Nakarattars. These services included, in addition to provision of lodging and meals, provision of mailing facilities, making travel arrangements, Clearing baggage at local customshouses, and arranging for absentee prayers at local temples. In short, vitutis were extremely useful in the mobile world of the Nakarattar. Vitutis were normally financed primarily by large gifts or endowments (kattalais) and operating costs were also subscribed through endowment. In addition, every guest paid what amounted to a nominal rent (called makinai, like the Nakarattar religious tithe) fixed by the manager of each Vituti and subject to revision according to need. Thus, many of the redistributive functions were performed by the endowment of temples and temple festivals were performed by the endowment of the closely associated nakaravituti. This housed a shrine dedicated to Lord Dhanday...
