A VMZINC standing seam roof in QUARTZ-ZINC® has been installed on the £6.8 million Ash Court student accommodation project at Girton College Cambridge. The new development, designed by Allies & Morrison, is an extension to the existing Grade II-listed college buildings and comprises 50 en suite bedrooms, a fitness centre and an indoor swimming pool. Passivhaus principles were followed in the energy-efficient design following ambitious environmental targets set by the college. Use of triple-glazed windows, heat recovery ventilation systems, photovoltaics, ground source heat pumps and an upgraded heating system resulted in RIBA Special Sustainability and Green Apple awards.
