NATURAL WIND PATTERN The way the blocks are arranged help in maximising the minds from the North East, North West, and the dominant South West Winds. The aerodynamics of the wind pattern suggest curved spaces to least obstruct wind flow and the Jaali helps in further accommodating the natural ventilation inside the buildings. This helps in reducing the need for Mechanical Ventilation,.

SOLAR POWER Solar Power generated on the roof top and with the solar pergolas help in achieving an efficiency and excess of power by 126%.. This excess power can be sold to the Grid after 3 years of operation and help in economic sustainability as well.
SOLAR PERGOLAS Alongside the Pedestrian Pathways, solar pergolas help in providing shade for the walkers and also increase the solar power quantity and efficiency on the site.

FENESTRATION & SHADING According to analysis and simulations done the shading devices width and depth have been calculated and smaller horizontal shading is designed along the Northern Side while the Southern facade not facing the hillock is designed with both vertical and horizontal shading. The fenestration is designed in accordance to ECBC with 40% WWR with more lighting streaming through the Northern facades which are utilised for reading activity.

RESULTS Caution: Photovoltaic system performance predictions calculated by PVWatts® include many inherent assumptions and uncertainties and do not reflect variations between PV technologies nor site-specific characteristics except as represented by PVWatts® inputs. For example, PV modules with better performance are not differentiated within PVWatts® from lesser performing modules. Both NREL and private companies provide more sophisticated PV modeling tools (such as the System Advisor Model at https://sam.nrel.gov) that allow for more precise and complex modeling of PV systems.
