Enabling business by reuse of basic building components – documentation of quality for second use

Project Details

Description

This project enables new business based on reuse of basic building components of concrete, wood and steel.

Today such business is hindered by lack of technology to document the quality of second-life components (SLCs), a classification system linking quality and next possible use, guidelines in the joint technical property and standards. In practice this means significant documentation burden and economic risk for the building owner who chooses SLCs, and consequently there is a lack of demand for SLCs - regardless the general demand for sustainable solutions from public and private building owners, and interest from demolishers to deconstruct and supply SLCs.

We will remove the barrier and equate the choice of SLCs and new components in regards to documentation burden and risk.

Environmental benefits from choosing SLCs compared to todays practice are significant, not at least the much reduced CO2 emissions. Thus, the ambitious national and European strategies on reduction in CO2 emission certainly favours SLCs - a strong base for business, national as well as international.
Our consortium is highly qualified to take the task and will benefit from it. We are industrial partners from supply and user side for SLCs, eager to develop the businesses, strong networking partners, ensuring wide commitment from stakeholders throughout the value chain, and strong research/innovation partners develop the needed techniques and standardization.

A key challenge in choosing second-life components in a building project today is the major barrier constituted by lack of standards, certification and documentation systems for these materials, thus entailing significant documentation burden and economic risk for the building owner, when choosing these components in a building project. We will overcome this barrier by developing the much needed systems and methods to equate the choice of second-life building components to new components and following enable business based on reuse.

To fulfill the purpose, the project has these four specific aims:
(I) Develop and standardize a classification system for second-life components with requirements to concrete, wood and steel.
(II) Develop and standardize non-destructive tests (NDT) as technology for documentation of technical quality of second-life components of concrete, wood and steel.
(III) Provide know-how and data for inclusion of NDT methods in technical guidelines in the Joint Technical Property.
(IV) Perform 3 full scale tests for data generation to assess the impact from the certified second-life components on environmental indicators (LCA) and overall economy (LCC) enabled by the developed classification system and technical methods.

When successfully overcoming the barriers, business within reuse of building components is open – our industrial consortium partners are ready to take the opportunity - and with such business follows new jobs and significant reduction in CO2 emissions.
