• One of the most used building facades is the Frameless, which offers beauty; proper sealing, simple installation, and convenient
loading. In this system, the surface of the facade is completely sub structured into a grid.
• The presence of sealing rubber around frames and glass makes the surface of the façade completely insulated (water and air
sealing) and the most important point of this system is that the surface of the facade is more uniform in terms of the material.
• Besides, opening windows are not visible. These reasons have made the system more attractive to most building designers.

• Concrete even though a material that retains heat can also be used to create a stable and efficient indoor environment with its

• Concrete can easily reflects heats as well as radiation when treated with suitable coatings that makes it a good and strong material

• Metals are the material that absorbs and reflects light to the surrounding making them a more suitable material for colder
climates.
• These provide huge design advantages as the material is very flexible not just physically but also in the scope of designing and
application on facades.
• The material is relatively a light weight one with huge designing possibility considering not much of structural constraints.
• Polymer façade uses various qualities and advantages of plastic as material for building facades.
• The material is extreme light weight as well as durable giving a good results structurally.
• Variants of this material can also be rendered translucent giving an interesting façade element that looks much different than the
conventional glass.
• The material is also weather resistant and the aesthetics can render the surface that can mimic other materials visually like wood,
metal, blocks, etc.

Introduction
• Sun Shading Devices inhibit the solar radiation (block,
allow, etc.) incident on a building and are used either
internally or externally or in between the internal and
the external building space.
• They can be any mechanical equipment (like dynamic
facades), projections (chajja), cantilevers, louvres, fins,
jaalis, or even textiles.
• They can be fixed, manual and automatic moveable.
• The primary objective of creating a comfortable internal
environment, that is, cool in the summer and warm in Use of shading
the winter. • Solar controls should be considered for all glazed
openings exposed to direct sunlight.
• Solar control is particularly important on south to west-
facing facades, since the solar gains will coincide with
the hottest part of the day.
Constraints of shading devices
• Sun path and wind direction are usually different.
• There will be a need for admitting controlled levels of
diffused daylight.
• In most cases there will be a requirement of views out of
the window.

CASE STUDY 2 – 72 SCREENS, (SANJAY PURI)
• Completed in April 2013, this office building is located in the city of
Jaipur, India which has a desert climate with average temperatures
ranging from 30°C to 50°C grade through most of the year.
• The concept of a jail is a traditional architectural concept in Rajasthan
and has been used to reduce heat gain, increase ventilation and
reduce noise from the busy traffic outside.
• The building is fragmented into triangular facets with jali as a
secondary screen all around it and the interstitial spaces are used for
plants to further reduce the heat gain creating a building that is
extremely energy efficient in response to the city’s 450c summer
months that are from mid-March to mid-October.
• The material used for jail is glass reinforced concrete.

UNIQUE FACADE DESIGNS
The scope of a facade is not just limited to a vertical wall, sometimes they frame the entire structure and form a vital part of the
design concept .The works of Frank O’ Gehry are the best example for this kind of detailing.
