Far more than an aesthetic cover, Green façade plays a major role in reducing building energy consumption and improve occupants’ comfort and well-being. 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.

But what can be the key consideration for a sustainable facade design?? 

Façade can typically influence the building energy consumption and the human interaction with the environment. Façade has to be designed keeping in both human comfort and the influence of the energy consumption.

For example: An ideal case scenario in the Indian context climate, north façade can have a maximum benefit of daylight, with little higher SHGC minus shading. South facade features with lower SHGC glass of north adding shading. However, east and west façade require high performance glass, shading and minimum window to wall ratio. 

These are some of the ways in building design which contributes towards sustainable façade design. If you want to know more Read the Article.
