Significant gains could be made if relevant evidence
was used to inform decisions
on how to best shape built environment around us.
But this is not easy.

The major obstacles are:  
the sheer volume of this evidence,
its obscurity and accessibility,
variation of the quality of the evidence.

Sometimes we do not need to reinvent the wheel
 – when good and unbiased reviews of evidence
or summaries of the topic already exist,
Why not use them?

By collecting and assessing best existing evidence and topic reviews,
we aim to make them more discoverable,
helping sharing the knowledge and good practice.
