GUIDANCE DOCUMENT ON PROCURING SUSTAINABLE BUILDINGS AND CONSTRUCTION
Procurement officers have a tremendous opportunity to greatly affect change and contribute to the sustainable development of built environments. This guide intends to provide a practical overview of the options and methods for procuring sustainable buildings and construction in developing countries and emerging economies. Primarily aimed at procurement officers, the main focus is on public procurement at a building scale. However, these concepts are applicable to institutional and private sector actors as well. This guide covers a number of procurement methods and processes, including newer methods of integrated project delivery (IPD) and public-private procurement. As the case studies indicate, these procurement methods show great promise for delivering sustainable buildings. This guide is focused on procurement at the building-scale, and therefore does not include specific guidance beyond the building system, for example the interface at the neighbourhood scale (e.g. distributed energy systems) and infrastructure including public transport, cycling, and pedestrian access. However, many of these same procurement examples can be applied at a different scale, such as zoning, neighbourhoods, or infrastructure. The guide assumes the reader has a basic knowledge of the building and construction process. Further, it is not intended as an introduction to the concepts of “green” or “sustainable” building design. Instead, this guide uses short highlights of innovative and sustainable construction procurement across different sections to illustrate and inspire a transition toward more sustainable procurement. The report is structured as follows:
• Section 2 gives a general overview of sustainable public procurement, kindly provided by UN Environment who is leading the One Planet Network3 Sustainable Public Procurement Programme.
• Section 3 presents sustainable building and construction concepts and highlights the sustainability aspects.
• Section 4 explains procurement strategies and project delivery systems, target setting, working with markets, pricing, team selection and client responsibilities.
• Section 5 describes building certification and rating tools, and discusses indicators and their relationship with sustainable procurement, as well as legal frameworks.
• Section 6 deals with performance measurement and tracking.
• Section 7 explains strategies for calls for tenders.
• Section 8 contains examples of real cases, sharing lessons learned from procurement projects containing clear sustainable buildings and construction components.
• Section 9 summarises the recommendations.
