Performance That Stands The Test Of Time
What is a Green Building?
A green Building revolves around the conservation of natural resources; provides human
comfort, safety and productivity. This approach results in many tangible and intangible
benefits.
Sustainability
The biggest benefit is to create a sustainable world.
Operational SavingsGreen Buildings consumes fewer resources than conventional ones. This may come at an
incremental cost but gets paid back over a short period of time and it may even become
cheaper.
Occupant Health and ProductivityWorking in an environment with access to daylight and views provides a connection to
the exterior environment and boosts occupant health and productivity.

Occupant Health and ProductivityWorking in an environment with access to daylight and views provides a connection to
the exterior environment and boosts occupant health and productivity.
The American Institute OF Architects(AIA) have started to accumulate evidence that
suggests that access to daylight and views can positively influence productivity.
Satisfaction and physical health for building occupants means a higher quality of life. For
the employers of these occupants, this means higher profits.
Green Buildings ensure that waste is minimized at every stage during the construction
and operation of the building resulting in low costs to all from a simple commercial
complex to large development projects. As more developers, owners, consultants
architects and vendors are participating in the green building movement, it is now
starting to gather rapid pace in the country. The combined effort of individuals and
organizations to move towards green buildings is having a remarkable effect and this can
be seen in innovative constructions across India.
Some Of The Features Of A Green Building Are :
Ÿ Use of recycled and environment friendly building materials.
Ÿ Use of non toxic and recycled / recyclable materials.
Ÿ Use of energy efficient and eco-friendly equipment.
Ÿ Use of renewable energy.
Ÿ Effective operational control with building management systems.
Ÿ Environment protection.
Glass use in buildings
India is witnessing tremendous growth in infrastructure and construction sectors. As these
sectors grow rapidly, preserving the environment poses a lot of challenges and at the
same time presents opportunities. Glass has come to be the preferred choice of architects
for building envelopes and interiors. Glass is unmatched when meeting requirements of
form, function and beauty. Transparency, day lighting, spaciousness and liveliness have
driven extensive use of glass in buildings. With more glazing, there remains the challenge
of reducing building energy consumption and conserving natural resources.
The construction sector needs to play a vital role in contributing towards environmental
responsibility. The green building movement in India is a step in this direction, to minimize
the negative impact of buildings on the environment.
Glass Coatings
In facade glazing, coatings on glass have proved to be an efficient way of reducing
energy consumption of buildings. Over the years, two technologies have dominated
architectural coated glass manufacturing.
Towards Greener Buildings
Minimising adverse environmental impact, has become and will continue to be the
global focus of development. Built environments contribute to a major share of our
energy consumption and consequently to environmental damage. Building sustainable
living and work spaces with minimum energy foot print is the need of the hour. In a
cooling dominated climate, the chase is increasing daylight while cutting off energy
ingress into conditioned space through building envelopes.
Light Vs Solar Heat Gain ConundrumAllowing more daylight into conditioned space has the corollary of allowing more solar
heat gain. High performance, spectrally selective coatings on glass today, are
challenging this corollary and are inching closer to achieving the ideal “visible light
tower” curve of the solar spectrum.

Ideal Applications Of Fresca
Ÿ Leed rated building facades
Ÿ Energy conservation projects
Ÿ Hotels
Excellent daylighting with very high solar energy blocking.
Low solar factors even with clear substrates.
Certified for green buildings
Wide choice in appearance and performance
Close to natural colour rendering of views
Superb aesthetics with German processing.
Just one sputter coated glass in IGU configuration
The Performance Advantage
Sezal Proposition- Fresca High Performance
Sezal brings Fresca, a European technology, high performance, insulating glass series,
ushering the age of Formula One performance in architectural glass. The structure of the
deposited layers in a coated glass is extremely vital for achieving the desired performance
levels. The pulse sputter technic employed by arcon represents a significant breakthrough
in the large area coatings on architectural glass. The high strike energy of the metal
atoms in this process ensures the formation of dense, homogenous and continuous
layers with excellent photometric and radiometric properties. The carefully selected
coatings and the technology perfected over three decades ensure excellent bonding to
the glass substrate, durability, chemical and abr Fresca is the ideal solution to green built
environments.
FRESCA
The USP of Fresca
Occupant Comfort
When building interiors offer copious daylight and views of the outdoors, the people inside
thrive. Workers are more productive, students learn better, and patients heal faster.
Artificial light, glare and overheating have the opposite effect.Fresca enables the
embracing of natural light and connection to the outdoors while preserving the comfort of
indoor space. Occupants enjoy all the benefits of sunlight, without the drawbacks that
come with it.
Improved Energy Performance
Fresca minimizes the use of energy and expenses associated with operation costs of a
building. It is estimated that savings generated with such facades can amount to almost a
quarter of the total expenditure.
Sustainability
If sustainability is a requirement, Fresca provides it. Buildings can use smaller, more
efficient HVAC systems, dramatically reducing energy consumption. A low carbon
footprint should be factored in the construction materials, as they are a particularly big
concern while striving for sustainable construction.
LEED
Gathering LEED credits by maximizing the use of natural light in buildings for the well-
being of the occupants makes Fresca an environmentally preferable product for LEED
building construction.

Color Rendering Index (CRI)
The ability of transmitted daylight through the glazing to portray a variety of colors
compared to those seen under daylight without the glazing. Scale is 1 - 100. For instance,
a low CRI causes colors to appear washed out, while a high CRI causes colors to appear
vibrant and natural. In commercial glass, CRI indicates the effect the specific glass
configuration has on the appearance of objects viewed through the glass. Heat gain is
heat added to a building interior by radiation, convection or conduction.
Heat Transfer Methods
Heat transfer occurs through convection, conduction or radiation (also referred to as
"emission"). Convection results from the movement of air due to temperature differences.
For instance, warm air moves in an upward direction and, conversely, cool air moves in a
downward direction. Conduction results when energy moves from one object to another.
Radiation, or emission, occurs when heat (energy) can move through space to an object
and then is transmitted, reflected or absorbed.
Light to Solar Gain
Ratio of the visible light transmittance to the Solar Heat Gain Coefficient. A higher LSG
ratio means sunlight entering the room is more efficient for daylighting, especially for
summer conditions where more light is desired with less solar gain. This ratio is the
measurement used to determine whether the glazing is "spectrally selective."
Low-E Coatings
Relatively neutral in appearance, low-E coatings reduce heat gain or loss by reflecting
longwave infrared energy (heat) and, therefore decrease the U-Value and improve energy
efficiency. Current sputter-coated low-E coatings are multilayered, complex designs
engineered to provide high visible light transmission, low visible light reflection and
reduce heat transfer.

Relative Heat Gain (RHG)
The total heat gain through glass for a specific set of conditions. This value considers
indoor/outdoor air temperature differences and the effect of solar radiation.
R-Value
A measure of the resistance of the glazing to heat flow. It is determined by dividing the U-
Value into 1. A higher R-Value indicates better insulating properties of the glazing. R-Value
is not typically used as a measurement for glazing products and is referenced here to
help understand U-Value.
Shading Coefficient (SC)
An alternative measure of the heats gain through glass from solar radiation. Specifically,
the shading coefficient is the ratio between the solar heat gain for a particular type of
glass and that of double strength clear glass. A lower shading coefficient indicates lower
solar heat gain.
Solar Energy
Radiant energy from the sun having a wavelength range of 300 to 4000 nm, which
includes UV (300 to 380 nm), visible light (380 to780 nm) and near infrared energy (780 to
4000 nm).
% Reflectance Out - percentage of incident solar energy directly reflected from the glass
back outdoors.
% Absorptance - percentage of incident solar energy absorbed into the glass.
% Transmittance - percentage of incident solar energy directly transmitted through the
glass.
The sum of percent reflectance out + absorptance out + transmittance = 100%. An
additional consideration is emission, or emissivity. This refers to the reradiation of
absorbed energy that can be emitted toward both the exterior and interior of the building.
Emissivity is controlled through the use of low-emissivity, or low-E coatings.
Solar Heat Gain Coefficient (SHGC)
The percent of solar energy incident on the glass that is transferred indoors, both directly
and indirectly through the glass. The direct gain portion equals the solar energy
transmittance, while the indirect is the fraction of solar incident on the glass that is
absorbed and re-radiatedor convected indoors.
Solar/Reflective Coatings
Typically, highly reflective coatings that reduce solar heat gain through reflection and
absorption. Though very effective at reducing heat gain, visible light transmittance is
generally low and U-Values are not as energy efficient as low-E coatings.
Transmittance Percent
Percentage of incident ultraviolet energy that is directly transmitted through the glass.
Long-termexposure to UV light may result in fabric and pigment fading, plastic
deterioration and changes to the appearance of many types of wood.
UV
Ultraviolet radiant energy from the sun having a wavelength range of 300 to 380 nm with
airmass of 1.5.
U-Value (U-Factor)
A measure of the heat gain or loss through glass due to the difference between indoor &
outdoor air temperatures. It is also referred to as the overall coefficient of heat transfer. A
lower U-Value indicates better insulating properties. The units are Btu/(hr)(ft2)(°F).
Relative Heat Gain (RHG)
The total heat gain through glass for a specific set of conditions. This value considers
indoor/outdoor air temperature differences and the effect of solar radiation.
