2. INTRODUCTION
FAÇADES AND ENVELOPES
BUILDING ENVELOPE
 separates indoor environment from outside environment
providing comfortable indoor environment through an
appropriate balance of passive and active technology.
 Building envelopes are designed with respect to
environmental, technological, socio-cultural, functional
and aesthetic determinants.
 Building envelopes consists of the roof, walls, slabs ,doors,
windows, etc.
 The major focus in designing buildings is on making them
sustainable by reducing energy consumption without
compromising on user’s comfort.
 ‘façade’ can refer to any predominantly vertical face of a
building envelope, such as an external wall.
 A façade refers to one side, usually the front, of a building.
It is an integral piece to the overall design of a building.
 It provides the opportunity to create a personality and
character to a building.
 The façade can be living, mechanical, or false depending
on the architectural design.

4. CLASSIFICATION OF FAÇADE AND ENVELOPES
FAÇADES AND ENVELOPES
CURTAIN WALL DOUBLE SKIN FACADE CLADDING/PANELLING
• The framing is attached to the
building structure and does not
carry the floor or roof loads of
the building.
• The wind and gravity loads of
the curtain wall are transferred
to the building structure,
typically at the floor line.
• The double-skin facade is a system
of building consisting of two skins,
or facades, placed in such a way
that air flows in the intermediate
cavity.
• The ventilation of the cavity can be
natural, fan supported or
mechanical.
• the external appearance of a
building. Mostly, the term is used
when making reference to design,
style or color.
• External cladding, on the other
hand, refers to an external
protective layer that protects and
beautifies a building envelope

6. GLAZED ENVELOPE - FRAMELESS CURTAIN WALL
FAÇADES AND ENVELOPES
• 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.
GLASS FINS TENSION CABLES VERTICAL TRUSS SYSTEM CABLE NET SYSTEM
TYPES OF SUPPORT SYSTEM
An exclusive structural wall system
comprised of facade glass panels
and vertical glass mullions designed
to resist site specific design loads.
These are suspended from minimal
stainless steel tension rods or pre-
stressed cables. Almost invisible to
the eye and completely frameless.
Non-structural truss that extends from a
structural wall system solely for the
purpose of holding cavity fill insulation.
Also known as a Larson Truss.
A specially designed glass wall where
the construction carrying the glass is of
stainless steel cables stretched in a cross
weave, creating a delicate appearance

FAÇADES AND ENVELOPES
SPERTUS INSTITUTE OF JEWISH STUDIES CHICAGO
The building is innovative and environmentally sustainable.
It is a 10 storey building: 161 feet tall and 80 feet wide. The geometry of the
façade is unique because the surface tilts in three dimensions.
The lightness of the wall and absolute minimal use of materials offer great
efficiency and sustainability. façade’s dynamic crystalline form allow light to
extend into the narrow building Individual units of glass that are
parallelograms rather than rectangles.
STICK-TYPE CURTAIN WALL GLAZING SYSTEM UNITIZED FRAMING SYSTEM
keeping in mind the shape of the structure making it flat and not
convex glazing sheets to reflect harsh heavy rays. Hence double layer
glass set with extruded aluminum frames were provided The glass is
positioned vertical in the frame and segmented around the tower. This
is to avoid the distortions due to the heat treatment of the glass.

8. CONVENTIONAL ENVELOPE
FAÇADES AND ENVELOPES
• Manufactured with natural and aged raw clay without other
chemicals, fired at high temperatures, terracotta cladding is an
architectural cladding material that provides certain degree of
thermal insulation and weather resistance while creating an
aesthetically pleasing facade.
TERRACOTA STRUCTURE TIMBER STRUCTURE
Ho chi minh house by Sanuki Daisuke Architects chose terracotta for its
relatively low cost. The perforated blocks also provide natural
ventilation and cooling by shading, while still maintaining privacy from
the street. This helps filter the harsh sunlight
Diamond and floral motifs are cut through the terracotta
facade fronting the building
The Miramar house has wooden shutters which permit the residents to
be in charge of the interior temperature of the house. Moreover, they
give the needed privacy for the owners. The lower story is separated
from the outside by gliding transparent doors while the upper one is
equipped with a wooden-shutter arrangement.
Flexibility in use, as it can be made into various forms and profiles
Adaptability, as it can be equally adapted to offsite or factory construction
Technically simple, as it utilises simple, tried and proven construction and
erection technologies. Lightweight, making it easy to transport and handle
Aesthetics. Timber facades can also be creative, and used to add visual
interest and help a building tell its story Low carbon footprint.

9. CONCRETE ENVELOPE
FAÇADES AND ENVELOPES
• Concrete even though a material that retains heat can also be used to create a stable and efficient indoor environment with its
envelope.
• Concrete can easily reflects heats as well as radiation when treated with suitable coatings that makes it a good and strong material
for structures.
• As a rigid material, it can with stand the toughest of weather and same time maintaining a better inside environment and is best
for sound proofing also.
CONCRETE FOLDED PLATE STRUCTURE
Mülimatt Gymnasium by Studio Vachini, Switzerland
The folded plates are made up of pre cast concrete panels on façade
and roof. The roof is rigid while the façade have triangular glazing that
gives an interesting form. The concrete not only helps in structural
loads but also provides better climate control for a relatively cold
climate of Switzerland. The glass glazing also helps in retaining heat
that helps in less heating loads in winters. The exposed concrete also
gives a bold aesthetic to overall structure.
CONCRETE SHELL STRUCTURE
PALAZZETTO DELO SPORTS by Pier Luigi Nergi, Rome, Italy
A 60m diameter in plan, this structure comprises of an indoor large
stadium that was made to serve as a location for 1960 Olympics. The
roof is made up of concrete shell supported by concrete ribs. At the
center top of the dome, an opening was provided for stack ventilation
as well as day light that inspired from the Pantheon. Smooth surface of
dome helped reflect the light back. The stack effect consists of air
entering from sides and exiting from top.

10. METAL ENVELOPE CLADDING
FAÇADES AND ENVELOPES
• 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.
ALUMINIUM CLADDING
ESSEX CROSSINGS by SHoP Architects, New York City, USA
A very slight twist that the Architect termed as ‘Torqued’ nature of
structure inspired the use of Aluminum panels for its flexibility. The
champagne colored aluminum sheets had a special coating that
catches the light but disperses instead of reflecting it on neighbors.
This gave an interesting glowing façade design that used reflectivity
and flexibility of aluminum material in a fascinating way.
STAINLESS STEEL CLADDING
LILLEHAMMER ART MUSEUM by Snøhetta, Norway
The art museum in Norway used a very unique expression of shooting
star blasting through the universe giving a rippled effect. This was very
much evident on the façade block that was made completely out of
stainless steel. Using the flexibility of material, the façade actually
consists of the undulations that go 250mm deep at its maximum
differences in levelling. Another reason of using the material is
corrosion resistance feature of the metal stainless steel.

11. POLY MER FAÇADE CLADDING
FAÇADES AND ENVELOPES
• 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.
POLYCARBONATE PANELLING
HARVARD ART LAB by Barkow Leibinger, Harvard
The steel frame is clad in transparent insulated glass and lightweight
high-insulating polycarbonate panels. These panels range from
transparent to translucent to opaque, exploiting diffuse natural light
and a street-level view by day, emerging as a glowing “lightbox” by
night. These materials emphasize the building’s ephemerality while
providing a robust and adaptable space for the arts.
PVC FAÇADE PANELLING
PVC is a very flexible material with innumerable application in facades
for paneling. Being a weather proof and light weight material is the
biggest advantage of PVC for paneling. The panels can render wood in
best way giving the appearance in a budget friendly way. This cladding
have acoustical advantages as well in some cases.

15. NEW FACADE MATERIALS
FAÇADES AND ENVELOPES
• Translucent concrete is a concrete based building
material with light-transmissive properties due to
embedded light optical elements — usually optical fibers.
• Light is conducted through the stone from one end to the
other. Therefore, the fibers have to go through the whole
object.
• This results in a certain light pattern on the other surface,
depending on the fiber structure. Shadows cast onto one
side appear as silhouettes through the material
• The pavilion design is a square plan of 3,600
sqm for a height of 20 m
• The building is grazed on three sides by a
water blade which reflects and redoubles it
so as to intensify its natural light effects.
• Covered with ‘transparent concrete’, a
material of latest conception made up of
concrete and polymers;
• In fact, the project proposes a building which,

• With the aim of supporting architects to become active agents of sustainable design, facades that incorporate different recycled
materials are being used.
• Beyond the typical uses of plastic and glass, innovative materials such as mattress springs, ice cream containers, plastic chairs, and
recycled waste from agricultural and industrial products are also being used to create an attractive facade.
RECYCLED TILES
STRUCTURE: Ningbo Historic Museum, China
The architects designed the façade of the building as if it was the surface
of a mountain comprised of massive reinforced concrete walls, partly clad
in recycled terracotta and clay tiles. By recycling materials from the
demolished buildings that once constituted the existing site, Wang and Lu
were trying to recall a past that was almost forgotten. In Wang and Lu's
design, the past has been turned into the permanent inner lining of the
formwork, providing a randomly decorative coating.
RECYCLED AGRICULTURAL AND INDUSTRIAL WASTE
PRODUCTS
STRUCTURE: Backyard Cabin, Oakland
Over 4,500 3D-printed ceramic tiles clad the exterior of the
building. Up-cycled agricultural and industrial waste products,
and at times its custom materials. Grape skins, salt, cement, and
sawdust, among others, have been integrated to create variety
among the tiles.

STRUCTURE: The Luxury Pavilion, Dubai
The outer skin of the pavilion is a mesh of
entwined bedsprings that naturally lends itself
to an organic form, floating amongst the
surrounding buildings.
RECYCLED BEDSPRINGS
STRUCTURE: The Recycled Pallet Pavilion
The office is oriented to identifying design
strategies towards ecology, flexible systems,
biodiversity, and recycled materials in the
urban context. The 100 square meters
detachable structure is made up of
prefabricated pallets forming an articulated
wooden diamond structure.

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
the winter.
Use of shading
• 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.

• The project concept is inspired by the traditional Islamic object the
“Mashrabiya” and motifs to stand out with two circular towers
covered by a honeycomb-inspired structure and its automated
dynamic solar screen.
• The “Mashrabiya” is a wooden lattice screen found in traditional
Islamic architecture and used as a device for achieving privacy and
environmental control including natural ventilation, solar control, and
glare reduction.
• The pioneering shading screen of the towers, controlled by computer,
operates as a curtain-wall, positioned two metres from the exterior
façade of the buildings in an independent frame.
• Each triangle is covered in micro-perforated glass fibre and
programmed to respond to the movement of the sun in order to
reduce the solar gain and glare.

• 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.
