Daylight & Ventilation Solutions designed, supplied and installed two Passivhaus certified glass roofs for the University of Leicester’s Centre for Medicine: the largest non-residential Passivhaus building in the UK.

Each measuring 6.5m x 15.6m, the two glass roofs utilise the well proven Lamilux PR60energysave system, installed with a surface inclination of just 3º. This project is among many Passivhaus rooflights installed by DVS, the first UK rooflighting business to specialise in Passivhaus projects An innovative daylighting solution – for a landmark in sustainability.

As the world’s first Passivhaus certified glazed roof system, the PR60energysave sets the benchmark for energy efficiency standards for atrium glazing. It has been independently assessed by the Passivhaus Institute and awarded the highest efficiency rating, the phA Advanced Component classification.

The system features a Ucwi value for the complete skylight of <= 0.82 W/m²K, utilising warm edge triple layer glazing with SuperSpacer, as standard.

The aluminium extruded mullion/transom glazing bar system allows for designs of any shape, inclination and size and can be supplied in any RAL colour.

At the University of Leicester Centre for Medicine, the two atria feature glazed vertical sections with six opening vents in addition to the glass roofs, bringing high levels of daylight and natural ventilation to public areas within the building.
