One important issue for the revitalisation of a brownfield is to answer the question how to deal with the remains of buildings in a sustainable way. In order to provide the basis for adequate decision making by site owners, investors and developers concerning the deconstruction and re-use of existing buildings and structures on brownfields, TIMBRE project's Work Package (WP) 5 is to develop strategies, tools and instruments supporting decision makers in deriving efficient in as much as environmentally friendly strategies. In the last deliverable D5.2 – Hagemann et al. (2013) – environmental friendly and economical methods of re-use of buildings and use of building rubble have been introduced. The report can be downloaded from the TIMBRE website www.timbre-project.eu. All deconstruction or refurbishment measures cause emissions influencing workers, neighbourhood and the environment. This Deliverable 5.3 as a Technical Guideline provides a definition of emissions, the legal frame within the EU, a description of the different emissions resulting from deconstruction measures and methods for reduction of and protection from emissions. This report – in a nutshell – leads to the following results: The main emissions of a deconstruction measure affecting the environment and neighbourhood are • Dust, • Noise, • Vibrations, • Contaminants. Their appearance depends on the type of building and its former use, the used building materials and the applied deconstruction steps and methods. The main basis for the prediction of emissions and required protection measures is a detailed inventory of building materials and contaminants and planning of the deconstruction workflow. With regard to the neighbourhood, environment and influenced protected goods, protection and monitoring measures are described.
