Profitable Net ZEBs - how to break the traditional LCC analysis

Berggren, Björn LU ; Wall, Maria LU and Togerö, Åse (2017)
Abstract
Global warming and an increasing population needing more buildings are important issues ahead. Hence, Net ZEBs and green buildings is one of many necessary measures for climate change mitigation. Some studies indicate that improved energy and/or green performance in these buildings may not be profitable. However, a short time perspective and narrow concept for evaluation may be wrong. This study presents two different built Net ZEBs in Sweden, with verified plus energy performance in user phase. Furthermore, it presents an economic analysis, based on life cycle costing (LCC), where additional green values are included in the analysis. The study shows that the, discounted, cumulative annual cost reductions due to green values exceed the... (More)
Global warming and an increasing population needing more buildings are important issues ahead. Hence, Net ZEBs and green buildings is one of many necessary measures for climate change mitigation. Some studies indicate that improved energy and/or green performance in these buildings may not be profitable. However, a short time perspective and narrow concept for evaluation may be wrong. This study presents two different built Net ZEBs in Sweden, with verified plus energy performance in user phase. Furthermore, it presents an economic analysis, based on life cycle costing (LCC), where additional green values are included in the analysis. The study shows that the, discounted, cumulative annual cost reductions due to green values exceed the initial extra cost after roughly five years. More research should be carried out in order to develop the methods and equations presented here and to gain more knowledge regarding reduced employee turnover, reduced sick absence, increased productivity, etc. in green buildings.
