Abstract: Approximately 5% of India’s total construction currently embraces sustainable design, indicating significant potential in the Indian market. The key to successful building design lies in the integration of both passive & active techniques. Emphasizing passive strategies are essential due to their cost-effectiveness & superior efficiency compared to active methods. For truly achieving sustainability it is imperative to prioritize passive strategies tailored to the local climate. Active techniques should function as supplementary elements rather than overshadowing passive approaches. The study concentrates on comprehending passive design strategies specific to India’s composite climate by analyzing case studies of various office buildings. The investigation delves into passive strategies such as orientation, fenestration, shading devices, earth touch, roof gardens, water features & landscaping. The proper use of passive techniques promotes energy saving.
