Abstract
A sustainable transition of the existing dwelling stock towards carbon neutrality is a key element in tackling the climate crisis. To facilitate this transition, one-step deep renovation, demolition followed by new build (i.e., reconstruction) and step-by-step renovation are possible pathways. The choice between these three pathways will depend on many aspects, but how does their environmental impact relate? Lowering the operational energy use is a first essential step, but the environmental impact related to the material use can become equally or even more important in case of low-energy buildings. Today, a systematic comparison of these three pathways from an environmental life cycle perspective is missing in the state-of-the-art. Hence, this paper compares the environmental impact of one-step deep renovation, reconstruction and step-by-step renovation with the conservation of an uninsulated single-family dwelling. The environmental impact is calculated by means of a Life Cycle Assessment (LCA) over a 60-year study period following a cradle-to-grave approach. For each pathway, identical strategies for the different building envelope components and technical installations are assumed. For step-by-step renovation, six steps in two sequences are considered, corresponding to the highest and lowest resulting environmental impact. The results show that one-step deep renovation has the lowest environmental impact, followed by reconstruction. Their environmental impact is respectively 73% and 68.5% lower than conservation. Step-by-step renovation has a higher impact than both one-step deep renovation (+26% to +73%) and reconstruction (+7% to +48%), but the impact is still 53% to 66% lower than conservation, depending on the sequence of the measures.
