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 Savings Green 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 Productivity Working 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 Conundrum
Allowing 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.
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.
The Performance Advantage Excellent daylighting with very high solar energy blocking. Low solar factors even with clear substrates.

Just one sputter coated glass in IGU configuration
Ideal Applications Of Fresca 타 Leed rated building facades 타 Energy conservation projects 타 Hotels
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 wellbeing of the occupants makes Fresca an environmentally preferable product for LEED building construction.
A green building is one which uses less water, optimises energy efficiency, conserves natural resources, generates less waste and provides healthier spaces for occupants, as compared to a conventional building.

Glossary 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 UValue 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)(째F).
