Guidance introduction

The Building Greener guidance document is now available from the CIRIA bookshop. Visit the CIRIA website to order a copy of CIRIA guidance C644.

What is the guidance about?

The guidance is an easy-to-use resource that explores the planning, design, construction and maintenance issues surrounding the incorporation of green roofs, green walls and associated features in buildings. Particular attention is given to how these features can benefit the built environment by enhancing biodiversity, sustainable drainage and thermal efficiency.

The guidance addresses the incorporation of green roofs, green walls and associated features across a range of different property types for both new and existing buildings. It provides a comprehensive assessment of published information on green roofs and walls with further guidance on their design, construction and maintenance.

Terrestrial landscaping associated with or adjacent to buildings is not addressed, although consideration is given to the landscape context and how this provides opportunities or imposes limitations with respect to biodiversity, stormwater management and climate change mitigation and adaptation.

Who should read the guidance?

The guidance is intended for use by those who require independent advice on the planning, design, construction and maintenance of green roofs, green walls and other biodiversity features.
