V-Guard office in Kerala, India is a 12 storied green spectacle. Plants spill out from every floor turning the structure into a vertical garden. Architect formulated a building that would use natural light and ventilation. The south and the west of the building would have more plants to block the sun. The green-screen would be equipped with drip irrigation so that when the air passes through, it would become cooler. Therefore, the office does not use much artificial lighting or air conditioning. The façade of the building becomes an interesting play of lines, planes and plants.

It is a model that works in a place such as Kerala, India where the temperature does not cross 35 degree Celsius. With the plants that line the balconies, direct sunlight does not fall on the building. Hence, 90 percent of the building is not air-conditioned.
