Deshpande Foundation's Sandbox Startups @ Hubli

The Clients “Deshpande Foundation” required an iconic yet earth hugging structure which would not stand loud and be an iconic image of their simplicity. This encouraged us to see things differently, which inturn inspired us to work on a concept that is more climate responsive, envionmentally friendly and which would reduce the energy consumption and which would allow more natural light and ventilation into the spaces. The result of this thought process helped us design the form which is more funtion oriented than aesthetically pleasing. The green building concept was the key to achieve the client's requirement, this would save the maintenance costs in terms of consuming enery in the future. GREEN BUILDING.

GREEN BUILDING - refers to both a structure and the application of processes that are environmentally responsible and resource-efficient throuhout a building's life-cycle : from planning to design, construction, operation, maintainance, renovation and demolition. Green building often includes measures to reduce energy consumption - both the embodied energy required to extract, process, transport and install building materials and operating energy to provide servies such as heating and power for equipment. To reduce operating energy use, designers use deatails that reduce air leakage through the building envelope (the barrier between conditioned and unconditioned space) They also specify high-performance windows and extra insulation in walls,ceiling and floors. Another strategy, passive solar building design, is often implemented in low-energy homes. Designers orient windows and walls and place awnings, porches and trees to shade windows and roofs during the summer while maximizing solar gain in the winter. In addition, effective window placement (daylighting) can provide mode natural light and lessen the need for electric lighting during the day. Solar water heating further reduces energy costs. Onsite generation of renewablw energy through solar power, hydro power or biomass can significantly reduce the environmental impact of the building. Power generally the most expensive feature to add to a building.

PASSIVE COOLING EFFECT
Passive cooling is a building design approch that focuses on heat gain control and heat dissipation in a build in order to improve the indoor thermal comfort with low or no energy consumption. This approch works either by preventing heat from entering the interior (heat gain prevention) or by removing heat from the building (natural coling). Insulation in the building's envolope will decrease the amount of heat transferrd by radation through the facades. This principle applies both to the opaque (wall and roof) and transparent surfaces (windows) of the envelope. Since roofs could be a larger contributor to the interior heat load. Especially in lighter constructions (eg. building and workshops with roof made out of metal structures). Providing thermal insulation can effectively decrease heat transfer from the roof. Cross ventilation is an effective cooling strategy. However, wind is an unreliable resourse. Stack ventilation is an alternative design strategy that relies on the bouyancy of warm air to rise and exit through openings located at ceiling heaight. Cooler outside air replaces the rising warm air through carefully designed inlets placed near the floor.
