Changing trends: Soprema discuss the benefits of green roofing and biodiversity
The growing trend to embrace a greener more natural built environment has brought about huge interest in the role of green infrastructure and in particular green roofs, as they become specified on a growing number of mainstream projects. Many are realising it is important to consider green roofs when working on biodiversity plans for new and existing developments, to reduce the impact of the development on the environment. Project stakeholders from all sectors; commercial, housing developments, infrastructure and public sector, need to take responsibility for the potential damage of ecological areas and habitats. Urban development projects often have biodiversity that should be protected. Construction project stakeholders need to consider the ecological values of construction sites and how construction will affect this value.
Biodiverse green roofs are designed specifically to create a habitat that will attract a particular flora and fauna; whether replicating the original footprint of the building or enhancing the previous habitat. The growing medium is bespoke to each project, selecting indigenous plant species to inhabit the roof over time. Brown roofs can also be specified to promote biodiversity in such situations. Eco system opportunities provided by green and brown roofs provide potential havens for insects and birds.
Biodiverse roofs provide temporary and permanent habitats for vegetation and animals, particularly birds and invertebrates and promote local wildlife. Roof greening contributes to biodiversity and encourages a variety of wildlife and plants to thrive; they replicate natural environments and habitats that are lost to urban development.
Storm Water Management
Most green roofs contribute to surface water management and can reduce the requirement (and potentially costs) for surface water management infrastructure elsewhere in the development. It also reduces the risk of overloading the local sewerage system. Incidents caused by heavy rain are reduced as the green roof delays the discharge of water from the roof to the sewer system. Many local authorities recognise green roofs as a control measure in the course of ecological wastewater management. Through evaporation and transpiration the retained rainwater evaporates and cools the surroundings of the building.
Green roofs not only contribute towards the biodiversity of a building and surface water management but are becoming increasingly recognised that with skilled planning they can significantly benefit the functioning of a building, helping to reduce its whole life cycle cost on a number of fronts.
A Complete Green Roof Solution
Soprema has recognised the requirement for a complete green roofing system including waterproofing and insulation and designed a complete system solution specifically for the Irish market, in order to provide the building owner with a high performance solution and peace of mind. The Soprema green roof bituminous waterproofing system guarantees longevity and water tightness, whilst providing a root resistant barrier to the insulation and structure beneath, the green roof build up itself provides multiple benefits such as reduction in storm water run off, and contribution to biodiversity. The Soprema Technical Team can assist with bespoke green roof specification and product selection for your project. Soprema will be showcasing green roofing on stand B10 at Architecture Expo 2016, for further information contact Soprema: firstname.lastname@example.org
