PASSIVHAUS PLUS SCHOOL WITH SOLAR GREEN ROOF

Working alongside Optigrun partner DF Roofing, we were able to design a system that incorporated an extensive wildflower & sedum green roof combined with a 252 PV modular layout. Manufactured from recycled plastic, Optigrun’s Solarbase 15 units are secured with a ballasted load that fixes the support frames for the photovoltaics modules in place securely with the load of the green roof structure meaning there is no penetration of the waterproofing layer or roof itself.

The client required a specific variety of different plant species which was achieved by installing pre-cultivated wildflower and sedum mat to the pitched roof and lower entrance roof and planting sedum and wildflower plug plants around the Solarbase units.

A combination of drainage solutions were implemented taking into consideration wind calculations, varying structural requirements, build ups and roof pitches to deliver the exact specification required

There will be a high focus on sustainability in all areas of the school with, for example, outdoor learning with a lake and safe jetty to observe wildlife and encourage biodiversity. They will also grow some of their own food on site. The school will also support active travel and wherever possible seek to reduce energy consumption and waste.
