Sustainable Building Renovation

Preface

As a contracting authority with focus on numerous details when planning public tenders, it can be hard to work out which environmental characteristics to include as requirements in procurement documents to reduce climate impacts as well as environmental impacts. Adding the need to also reference standards related to works, supplies, or services – then things may start to look impossible!

This guide introduces the most known standardisation aspects and most relevant environmental aspects to consider when planning a tender within building renovation, demolition, and new construction.

It also indicates the context the requirements should be set in to start the journey towards sustainable procurement, and it shows how it can be documented using recognised standards.

The numerous references to related publications make the guide useable as a reference work, helping to understand different terms and how to use them correctly when developing technical specifications.

Training in sustainable building renovation

In the years to come, focus on sustainable development in the construction sector will only increase, and so will requirements to the sector in general, why it is important to start addressing the possibilities already available.

The guide does not aim at being a complete advice on how to reference all potentially relevant standards or all environmental aspects for all tenders on construction works. It aims at providing a first overall guidance for setting of requirements through examples and better knowledge on relevant terms to address.
