Two of the roofs on our All Saints Building in Manchester are getting a green makeover! We’re installing green roofs to make this building one of the most sustainable in Manchester and provide important habitats for insects and birds.
We’re committed to protecting and enhancing biodiversity, and are looking for ways to increase and improve habitat diversity across our campuses.
We’ve begun to encourage and preserve local wildlife and habitat linkages across our managed estate, using landscape redevelopment opportunities, and have a programme of improvements which will be carried out by 2015. These include enhancing wildlife refuges to increase biodiversity.
In February 2011 the roofs of the All Saints Building changed colour from grey to green. Two green roofs were installed on the upper and lower roofs of the MMU’s All Saints building covering a total area of 607.2m² which alongside the green roof on the newly built MMU Business School will collectively make these the biggest green roofs in the City of Manchester.
A green roof is a layer of vegetation that sits on top of an existing roof structure. Green roofs come in many shapes and guises but generally the main distinction is based on whether the roof is extensive or intensive.
The two green roofs on the All Saints Building can be classified as Extensive green roofs and both have been planted with sedum / stonecrop plants. The green roof construction contains a number of different layers as can be seen from the diagram below. Each layer performs a specific function, the drainage board for example retains rainwater for irrigating the plants and the insulation layer helps to prevent loss of heat from inside the building below.
Green Roofs don’t just look pretty – they provide a range of benefits:
Staff and students from the MMU will be monitoring the impact that the new green roof has on energy insulation by using thermal imaging cameras to detect how much heat is lost from the roof space below. A baseline survey has already been undertaken to establish how much heat was lost before the installation of the green roof.
A camera has also been installed on the roof that will be able to provide a live feed to students and to assist with recording bird and insect species visiting the roof.
The All Saints Green Roof project has been developed in partnership between the Manchester Metropolitan University, Community Forests North West Limited, Red Rose Forest and Manchester City Council as part of the wider Corridor initiative.
Funding for the project has been provided by the MMU, Manchester City Council and the European Union’s INTERREG IV B fund as part of the VALUE Project.
