Policy brief and business case of building transformation

In practice, buildings’ survival depends on decisions made in urban planning as well as by the owner. Therefore, a combined policy brief and business case document is developed in order to inform both worlds of the other’s perspective in a single document. The document takes into account embedding information on environmental impacts of different transformation scenarios in GIS to inform planners (the policy brief aspect) in addition to elaborating on the different transformation alternatives’ life-cycle economic implications and multi-criteria decision-making that embeds environmental and cultural values into the return-on-investment considerations (the business case aspect). The deliverable is mainly targeted at municipal authorities, urban planners and building owners.
