NIIT University Dinning hall extension project is a seemingly modest 7000 sqft expansion of the existing campus dining facility. However the buildings pivotal location in the master plan, as well as, the act of negotiating the shift in the landform, offered an opportunity to create a multivalanced insertion. Set in the hot, arid outpost of Neemrana district, Rajasthan, the project also set out to achieve a contemporary yet sustainable expression and one that reinforces a sense of community.
With the campus population nearing 2,000 students; the existing dining hall located on the ground floor of the P.G.1 hostel needed more seating space and as per the master plan was to be situated at the eastern end of the linear central court, between the two P.G tower blocks. The proposed building extension acts as a social-interface block between this shaded court on one side and the U.G. hostels towards the east. With a grade difference of nearly 3.5 meters between this interface; the two level building also acts as a possible 'connector' for the large number of students moving between their dorm rooms and classrooms. The spatial and structural organization of the largely open floor-plate building is punctuated by a generous folded-plate staircase that acts as an internal public ramp; connecting the two levels effortlessly and facilitating students live-work flows.
At the upper ground level the the external entry portico engages with the P.G.2 hostel buildings' student common room/spaces. The large louvered opening along the west facade animates the central lawn and the academic quadrangle to the west. On the eastern face, series of vertical slit windows-set into the cantilevered volume of the dinning hall- frame views of the cascading Aravali range.
Given that the two-level building was to be inserted between existing Hostel blocks along the North and South face, meant having to deal with the east and west sun in the hot inhospitable Rajasthan climate. The desire to connect with the views to the hills and existing quad on the west generated large fenestration shielded by an array of shading strategies. On the east side, the upper floor projects out by almost 8 feet, shading the large horizontal glazing below. The visual interaction between the lower hall and the landscaped plaza outside creates a powerful social dynamic especially during evenings when students gather after a day in the classrooms. This outdoor room, along the Common Surface- NIIT's parlance for the pedestrian friendly street- has an intimate quality to it, thanks to the sheltered feeling provided by the cantilevered volume/box above and the shaded space it offers throughout the day. The deep-set window along the west facade, derives its angled fin expression, from a study in solar shading and yet opens out views to the green court.
The solar canopy with it's large overhang, shades the roof slab and facades from the overhead sun for most part of the day and also helps reduce heat gain by creating a ventilated air gap/cavity. The central part of the roof incorporates a green terrace that with its high thermal inertia, acts as a heat buffer and also helps mitigates heat island effect in the spaces around the building.
With minimized solar gains, the building the building design set out to minimize the energy (and operation costs) that went into cooling it at peak summer days. Expanding upon the pioneering earth tunnel cooling work already done at the campus by Dr. Vinod Gupta, the projects incorporates a hybrid evaporation cooling technology based on displaced ventilation for its minimal cooling needs
