Delivering the energy saving potential of modern glazing

In 2030, European buildings would consume nearly 30% less energy if they were all glazed with high performance glass, according to the latest research commissioned by Glass for Europe.

The reduction of energy consumption is one of the key goals defined by the European Union. Energy can be saved predominantly through buildings, which still consume huge amounts of energy.

Therefore, according to a recent Guardian Glass statement, it stands to reason that the subject of energy efficiency is widely discussed in the construction sector. In this context, the most popular are renewables and thermally insulating materials. It turns out, however, that facade glazing also has much potential.

The research ordered by Glass for Europe shows that the use of high performance glass can help to achieve the goal in a relatively short time.

Research for The Glass for Europe report ‘Glazing Potential Energy Savings & CO2 Emission Reduction’ was carried out by TNO and presents the analysis of two hypothetical scenarios.

These scenarios assume that by 2030 or 2050, all buildings in the EU will be fitted with the recommended type of glazing. In the first case, they would consume annually 29% less energy, which would translate into the reduction of CO2 emissions by 28%.

According to the scenario for 2050, the potential energy saving would be at the level of 37% with a similar reduction of CO2 emissions.

Estimates for the UK are even more optimistic. The use of the correct type of glass could in 2030 reduce the amount of energy consumed by buildings by 32% respectively. In 2050, it could be as much as 42%.

Interestingly, almost half of potential savings forecast for 2030 could be achieved in the first 10 years if highly selective glass is used in new buildings and doubled (from 2% to 4% annually) the coefficient of replacing old glazing with high performance glass.

In the scale of Europe, this would mean consuming even 200 Mtoe less energy and producing 240 million tonnes less of CO2.

The data from the Glass for Europe report demonstrates that highly energy-efficient glazing yields would significantly benefit the environment and reduce the need for heating and cooling.

Some of its important parameters include not only the thermal insulation coefficient (Uw) but also optimal solar radiation transmission (g).

Glazing that meets these criteria can be found in the wide portfolio of Guardian Glass. Highly selective glass products from the Guardian SunGuard range provide high light transmittance, while also controlling solar radiation transmission.

This helps to create well-lit spaces and to prevent overheating during summer months. In winter, on the other hand, the buildings may be effectively protected from the negative effects of heat transfer by thermal insulation coefficient Uw = 0.5 W/(m2K) (in triple glazing).

These properties make these products a common choice for modern and energy efficient buildings.
