Glass today, has become an integral part of modern day architecture. Using glass in a building instantly adds a touch of modernity to the living space. It not only gives the designers the choice of finish & a manifestation to their design aspirations, but also a wonderful chance to participate with the outside world. Glass, in fact, is the only building material which can not only give see-through properties but also the desired structural strength to be used in facades.

Glass ensures that the building gets ample natural light – making interiors look brighter and livelier reducing the need for artificial lighting and saving energy, or in other words, reducing the electricity bill. Ample light inside the home makes spaces look more spacious and roomy, an important factor to consider given today‘s shrinking living spaces in urban areas.

These Energy Efficient Glasses provide the benefit of reducing the heat gain in buildings due to its excellent energy saving properties without compromising on the natural light coming inside the building or the brilliant aesthetics that add value to the façade. And in winter, they ensure solar gain. So that no matter what the season, people inside stay comfortable at all times. Using energy-efficient glass also helps in ensuring that the interiors – and the occupants of the home – feel more comfortable. Ideal for solar and thermal insulating parameters, these glasses combine aesthetics with environmental sensibility and conform to all International and National Green Standards, making it the natural choice as a Green Building solution. Performance parameters of glasses like Visual Light Transmission, Solar Factor, U-Value and Internal Reflection make buildings more efficient and ecologically viable.

Energy efficient glasses, when used properly can reduce the total energy consumption by anywhere between 8~10% of the total energy consumed & hence the accrued benefits of using these glasses keep growing over the years. Furthermore, it is not just the recurring savings but also the reduction in the capex because of the lower energy loads required for conditioning the building. Typically the heat gained/lost through Glazing in a normal building in India is anywhere between 40~50% and using the right type of glass can bring down the energy consumption by 30~40% (only Glazing). The incremental cost for the high performance glazing can be recovered in a time span of 3~4 years.

Illustration (Cost Benefit Analysis): 


  • The above mentioned rates are assumptions used for energy and payback calculations only.
  • However the market rate will differ and include taxes and wastage charges.
  • HP refers to High Performance Glass

Post the detailed Building Analysis on Energy Performance and comparing with a base case, it is very clear  that HP 4is performing best with a payback period of 7.4 months and 67 % energy saving.

Until a few years back energy efficiency was neither a practice nor a fad in the country. However with the launch of the Energy Conservation Building Codes (ECBC), concurrently accompanied by the gain in popularity of the Green Building practices, users alike, builders & architects started looking at ways to reduce energy consumption in buildings.

So no matter which perspective you look at it from – aesthetics, modernity, elegance, adding a sense of space to interiors and of course, monetary savings – making homes energy efficient with glass makes perfect sense.

Smart Glass Market Growth will be driven by rising Global Energy Consumptions

By 2020 Global demand for High performance glass is set to rise as with the current trend & scenario with rising Environmental Issues in the Country. On one hand we want to build smart cities but on other hand existing Metros have very poor Air Quality.

Optimal Energy Savings is driving the smart glass market in the Commercial sector with few developers realizing the need of the country to save energy consumption for the occupied premises & save the Country’s Environment.

Despite high Energy cost the energy supply demand Gap is increasing. Switching to smart Glass for Government Building, Commercial Complex, and Residential Buildings, Schools, Hotels & even Shop fronts will optimize the consumptions.

Today’s smart glass helps a developer to achive more Light in & block the heat to largest extent.

Benefits of Smart Glass

  • Less Heat coming inside thereby increasing efficiency of the Building.
  • Saves Money on day to day Electricity consumptions.
  • More Light Entering helping in daylight planning.
  • Very Less Payback period against the initial capital investments.
  • Blocks UV rays thereby not fading the interiors like Curtains, Paints & furniture of the occupants.
  • Increases efficiency of the Façade on long term basis.
