Green façade plays a major role in reducing building energy consumption and improve occupants’ comfort and well-being. This makes sense in the construction industry to look at more holistic approach when it comes to Green façade design and deployment. A thoughtful façade can meet high expectation of performance for evolving green construction industry, owners and occupants. But equally important is to know what factors contribute to the façade design.The dominant factors while designing sustainable Green façade are location, site condition, climatic condition, orientation, sun path, function, building application, design and materials. These factors are not new to our building design; however, adopting such factors coupled with strategic use of daylight, glare control, shading, high-performance glazing and super windows improvise performance of a building overall and offers great opportunity to improve human comfort too. Green façade can act as a deciding factor of the overall performance of the building.To optimise overall building operating cost, there is need to have proper strategies to reduce conductive heat gain (unit measures in watts/sq ft) and later work on optimising active energy component such as HVAC, lighting, elevators and escalators, computers and other equipment in the building. Many high performance projects demonstrated EPI of <90 units/sq mt/year with improved strategies on both the façade and building materials and equipment. Day light percentage, shading factor, light shelves and types of glazing are the features in façade design capable of responding to building energy consumption in economical means, besides wall and roof options coupled with insulation.

While climate risk analysis is a relatively new field, rapidly developing sustainable infrastructure solutions such as sustainable buildings and renewable energy systems can be modeled with climate risk analysis tools.
The sustainable finance industry has been applying these tools to sustainable infrastructure investment, due diligence, and engaging with sustainable developers of new sustainable projects.
The changing culture of sustainable architecture in modern India, in practical terms of an active lifestyle and dynamic culture, has grown enormously.
