Narayana,

Loosely speaking it means giving an upgrade to the exterior of your place.

In real sense, it is deeper where the designer/architect tries to utilize the orientation of each side elevation. It could be done for example to bring in more air/sunlight save energy, curb view, or just plain aesthetics that she may want to improve upon.

Thanks,

Hello there,

Facade or elevation treatment is a term frequently encountered in concepts of green buildings and sustainable architecture.

It involves varying degrees of treatments starting from paints, textures, shading, illumination, orientation etc. to optimize the energy consumption and maximize day lighting.

It uses four sides and roof of the building to minimize energy costs by installing Solar PV, Shading structures to prevent harsh daylight, landscaping, sandwich walling etc. Also, it is essential to ensure aesthetics of the building stay intact and go with the house theme itself.

You could do a little experiment by yourself by tracing a solar trajectory for your current location and see how shading/ wall cladding improves your ambient indoor temperatures through facade treatment.

In which stage this activity comes, during interior design?

Except for retrofitting green systems, there's no need during interiors as it it related to outdoors mostly.
