It is fundamental to how PB delivers work that designers consider the best solution at every stage of a project.

The best solution should achieve a balance of social, environmental, and financial considerations, according to the objectives and direction of the client.

These guidelines are intended to be a quick reference. They are a collection of directions, tools, and information that designers and planners can reach for, no matter what phase of the project they are in.

Clients will ask for sustainability assessments, advice on the relative merits of various approaches to work, means for reducing their carbon dioxide equivalent emissions, and assurance that the funds they put forward for projects will deliver according to the triple bottom line.

This toolkit can help you find answers.
