Save energy with modern glazing with Guardian Sunguard®

In 2030 European buildings would consume nearly 30% less energy if all of them were glazed with high performance glass, according to the latest research commissioned by Glass for Europe. Highly selective, thermally insulating glass is already in Guardian’s portfolio and is widely used in modern, energy-efficient buildings.

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. Within the construction sector, renewables and thermally insulating materials have traditionally dominated the reduction debate. However latest research commissioned by Glass for Europe shows that the use of high-performance glass can help to achieve the goal of energy saving and CO₂ emission reduction in a relatively short time.

Data clearly demonstrates that highly energy-efficient glazing yields would significantly benefit the environment and reduce the need for heating and cooling. Important parameters to consider are the thermal insulation coefficient (Uw) and also optimal solar radiation transmission (g). Although not mentioned in the report, it is worth noting that the light transmission coefficient might also generate additional savings.

Maximize natural daylight, reflect solar heat

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, ideal for projects where natural daylight needs to be optimized while reflecting the optimum amount of heat away from the glass.

Buildings of tomorrow built today

Examples include the façade of London’s iconic, BREEAM Excellent certified “Cheesegrater” building with a 75,000 square metres façade featuring a curtain wall that is double glazed to allow for a high solar protection on neutral-looking glass. Two of Guardian’s products, SunGuard® SN 51/28 and SunGuard® SN 62/34, were used to help keep the building and its occupants cool thanks to their low g-value.

Furthermore, to the diagrid-patterned façade of the Victoria Gate in Leeds, Guardian SunGuard® SuperNeutral (SN 70/35) adds a unique sense of order and rhythm to the façade. The neutral blue colour of the SN 70/35 glass works beautifully with the subtle tones of the concrete, whilst flooding the arcade space in natural light.
