Enhanced Productivity for the Future of Retrofitting

Abstract

With the growing effects of climate change, it has become of great importance to reduce emissions from the building stock. Climate friendly retrofitting of dwellings has emerged as an important role since then. Based on a case study in the Netherlands and scientific research on the associated processes, it is concluded that the state of the current retrofitting process is not productive enough to meet European climate goals. To satisfy the increasing need for retrofitting, the Axiomatic Design Method is used to track down the key findings to improve the output of the retrofitting process from a holistic perspective. The aim of the research is to contribute to increase the current output of 50.000 residential retrofits per year by 300% for the Dutch construction industry. The results give opportunities for improvements that should be made within the process, product, and regulations in the industry. The elimination of manual labour in roof renovation is the finding that has the greatest impact on process productivity. In addition, the changeover of the process has an impact, whereby scaffolding, fall protection and weather no longer have an influence or are no longer required. It can be stated that efficiency could be significantly increased with low manual labour roof retrofitting.
