Shattering Myths…

…Establishing Facts!!

In Glass

Glass – A quick background

Glass is an

amorphous (non-

crystalline) solid

material

The word ‘Glass’ is

derived from the Latin

term ‘Glesum’ which

means transparent

substanc

Glass is typically

brittle and

optically

transparent

The commonly used

glass types are Flat

glass and Container

glass

Flat glass is a type

of glass, initially

produced in plane

form, commonly

used for windows,

glass doors,

transparent walls

and windshields and

of two types:

• Sheet Glass

• Float Glass

Container glass is

a type of glass used

for the production of

glass containers.

Is Glass Indispensible?

Unmatched aesthetics which allow architects

and builders to explore

unconventional building

shapes.

No deterioration,

corrosion, stains or

fading throughout

its lifespan.

Transparentto visible light.

Zero-degeneration and

easy maintenance which helps in

maintaining a clean

environment.

Can be recycled

indefinitely as the

structure of glass does

not deteriorate through

the process.

A Sustainablematerial.

YES.And for more than one reason!

Myth: Glass is only for Windows

When people think of glass for

a house, the first things that

come to mind are windows

and cookware.

That was in the past. With the

advancement of technology

and science, it is now possible

to manipulate glass at a

molecular level which makes it

take on countless other

capabilities making it ideal for

more than just windows.

Myth: Glass does not trap sound

Reality: Glass can be used for

sound insulation

Reality: Glass contributes to energy efficiency

Glass can be used as a building material

for energy- efficient architecture, based

on its application as well as the following

parameters:

•How glass is integrated with facade.

•Building typology

•Climate typology

•Orientation

•Site surrounding

•Design of the structure – Active or Passive

Real-Life Case Studies

Double skin facade – Combination of

perforated aluminum sheet & glazing

A school in Mumbai

How glass is integratedDouble skin facade

The non-solar heat gets trapped between the perforated aluminium façade and inside skin

when using a low-E glass.

Non-solar heat gain is the reason for increase in heat gains.

Daylight Analysis:

For a corporate building in Mumbai, daylight analysis was done

for Clear Glass (VLT = 78%) and the high performance glass (VLT =

21%). Both the glasses performed identically in terms of achieving

the optimal lux levels. Clear Glass, in fact, caused glare in certain

portions of the building.

Inclined Facade

• Daylight analysis is important as it prevents overdesigning of the building and at the same

time optimizes VLT requirement.

• In the case mentioned, we can use high performance glass which will reduce cooling load

without compromising on lighting load

Pink region shows area which

will have glare and Grey

indicates sub-optimal lighting

In 2nd case, we can see

reduction in glare area without

reducing optimum lux level.

VLT 78% VLT 21%

Office Building in Bangalore

Climatic condition of the location is important to select type of glazing

as different weather conditions have different impact on glass.

Climate Analysis

Glass with SF of 37 &

U-Val – 5.7 was as

efficient as a glass with

SF of 25 & U-Val – 3.7.

The building design &

the local weather

conditions meant that

you can relax the glass

values and still be

energy efficient.

Orientation

A commercial complex at Navi Mumbai with

glazing on the Eastern and Southern façade

showed that Clear Glass performed as good as

“high-performing glasses” and the choice came

down to aesthetics.

Shadow Analysis:

Right orientation reduces the

demand for high performance

parameters.

Shadow Analysis suggests the optimum requirement of Glazing

performance parameter to be used.

Passive Design

• A hotel building in Gurgaon

had avoided their demand of

high-performance glasses

just by adding shading

devices.

• Correct shading reduces

overall solar radiation intake

in the building and also

optimises light inside the

building.

Things to Note

• The same fenestration behaves differently

depending on the specific design.

• It should not be assumed that products

with Low U-value and SHGC are the best

and universal solution.

• Direct radiation falling on the windows

should be minimised.

• For shaded windows, products with lower

U-values perform better.

• For windows receiving high amount

of solar radiation, products with low SHGC

would perform better.

• Hence glazing should be selected after

thoroughly considering the design.

Ecosense – Made in India.

Made for IndiaThe Indian subcontinent is unique in its spread

of climatic conditions, and Ecosense has been

developed with this in mind. Manufactured

with the help of the best coaters and coating

development team and leveraging knowledge

based on studies of optimum parameters that

suit Indian conditions.

Ecosense makes sense in the Indian context

not just climatically, but also meets the needs

of Indian consumers who traditionally…

• …require cooling inside not heating

• …want to restrict solar radiation to come

inside rather than allowing it

• …want glass with optimally medium to low U

value rather than very Low U value

• …want optimum light to come inside not very

high light transmission.
