122 Leadenhall - 'The Cheesegrater'

The 75,000 square metres façade features a curtain wall that is double glazed to allow for a high solar protection on neutral-looking glass.

Fruit and Wool Exchange

The new-build façades are predominately brick-faced, with punched windows to reflect the surrounding context.

Caudwell International

Curved glass, punch windows and precast stone panels make up the envelope on a figure-of-eight footprint.

Sustainable, Energy Efficient Buildings with BIPV Solutions

The use of solar power to achieve higher energy ratings and reach Nearly Zero Energy Building (NZEB) levels for commercial buildings is a topic of increasing interest to architects, owners and developers of new builds and external envelope refurbishments. Current regulations in Europe are driving the demand for more innovative building solutions, particularly advanced energy saving and energy generation technologies. In January 2019, an EU Directive came into force that aims to drive the large-scale deployment of Nearly Zero Energy Buildings (NZEB). The objective of this directive is to considerably lower the energy consumption of buildings while using to a significant extent renewable energy, including energy produced on-site or nearby.



A powerful strategic partnership

Guardian has partnered with ML System S.A., a leading, well established company with more than 13 years’ experience in BIPV applications, to offer a complete range of BIPV product solutions, both semi-transparent and opaque, that help satisfy NZEB regulations.

How it works

Building-Integrated Photovoltaics (BIPV) is the integration of solar cells into the building envelope. Photovoltaic materials are used to replace conventional building materials in parts of the building envelope such as the roof, skylights, facades, canopies and spandrel glass. By simultaneously serving as building envelope material and power generator, BIPV systems may help reduce electricity costs, the use of fossil fuels and emission of ozone-depleting gases, as well as increase the value of the building.

See what's possible with BIPV glass

Among the key benefits of BIPV is the contribution into transforming the building into a Nearly Zero Energy Building and helping to achieve the best green building certifications such as BREEAM and LEED. Guardian can help you find the right BIPV solutions for energy-generating façades, both in terms of power and aesthetics, together with the best solar control glass coatings from the Guardian SunGuard® range – all integrated in a way that makes them almost unnoticeable.
