Increasing the Renovation Rate of the Building Stock Using an Approach Based on Economics of Scale

Reducing greenhouse gas emissions is a major challenge society faces today. This research aims to contribute to this by increasing the renovation rate of the building stock through a new approach benefiting from economies of scale. The aim is to move from the renovation of individual buildings to renovating full neighbourhoods or clusters of buildings. A model of the building stock is developed to spatially identify clusters of buildings with similar building characteristics that have a high energy use and renovation potential. Once these are identified, the greenhouse gas reduction of various renovation scenarios are assessed. For this purpose a bottom-up approach combining archetype buildings with GIS data, thermographic maps and energy use are used. Additionally, the
objective is to avoid burden shifting to other life cycle stages or environmental impacts and to ensure measures are cost-effective. The renovation measures are therefore evaluated by an environmental and economic life cycle assessment (LCA and LCC).

In summary, a new approach combining bottom-up building stock modelling with scenario modelling and life cycle assessment is developed to increase the renovation rate of our buildings and as such contribute to mitigating climate change. The findings are translated into a work and management plan to support cities in the governance of their building stock. Opportunities for the building sector are defined and recommendations are formulated.
