Sammanfattning
It is known that the construction sector accounts for a sizeable share of the total waste generated
annually. With various climate targets pushing towards sustainable development, this sector
needs to become more circular. Reusing materials and products is seen as having a great
potential in reducing the amount of waste and negative environmental impacts the sector has
today, although this is often easier said than done. Windows are considered to be one of the
more complex components to reuse. In addition, the conditions for implementing reused
windows differ depending on the type of construction process and building.
The aim of this master thesis was to identify the conditions of using reused windows into newly
produced, prefabricated multi-family dwellings, in order to present business strategy proposals
for companies within this area of business. A literature review was conducted to understand
what barriers currently exist and to identify main stakeholders that are to be involved in the
development. The theoretical framework was used as a basis for the interview study which
consisted of 10 interviews with stakeholders from different parts of the construction value
chain. The interviews were categorised to answer the question of which stakeholder should
drive the change, what business changes are required in the studied company, conditions on
how windows can be reused and how it can be applied in prefabrication.
The results showed that there is no single actor taking sole responsibility, as the whole sector
must embrace this reform. However, the actor that will have a major influence towards the
implementation of reused windows in prefabricated production are the client. The results also
showed that large parts of the buildings that will be dismantled in the near future have windows
installed that will not meet the current requirements. Further, the results also showed evidence
that the main obstacles are not related to prefabrication but occur much earlier in the value
chain. However, obstacles that needs to be addressed concerning prefabrication is increased
time- and cost aspects regarding uncertainties of attachments and design changes, as a result of
the standardized and otherwise effective lead times.
The conclusion drawn presents business strategy proposals for improvement potentials to
facilitate the reform towards using reused windows in prefabricated production. The proposals
concern internal business initiatives, prefabrication, and sectoral collaboration. Finally,
suggestions for further research on the topic are discussed.
