With an increased awareness of the impact of architecture on the climate, there is a widespread movement towards sustainable architecture in India. CPKA is one of the famous architects in India who have been incorporating this ideology in their designs since the very beginning of the practice. Each design begins with careful studies of the sun movement, wind direction, rainfall study, ground temperature analysis etc. During the design development wall, roof, glass, window-to-wall ratio, shading devices are carefully considered and incorporated. CPKA has achieved the unique distinction of being the first design firm in India to have acquired a US-based design practice, specializing in sustainability. Renewable design and energy options are kept at the fore-front making green architecture a stronghold of CPKA. A dedicated Sustainability Studio carries out studies for the same using advanced simulation tools.
