Increasing attention is being paid to the building sector due to its importance in the climate change debate. In recent years, a growing literature on the price premium paid by consumers to access more energy efficient and sustainable buildings has emerged as a common topic in hedonic model estimations. In this paper, we aim to provide a summary of this literature by conducting a metaanalysis of more than 50 studies from around the world. In this way, based on a random effects models and weighted OLS robust clustering estimations, we offer an average estimation of the price premium accepted by economic agents (in terms of sale prices) in order to enjoy energy efficient and sustainable buildings. This supports the argument that investing in building refurbishment is worthwhile and economically relevant. However, our data seem to show a major publication bias. Correcting for this bias leads us to halve the original estimation (from 8% to 4%). In addition, we analyze the sources of result dispersion by performing a meta-regression using different moderators (type of publication, bibliometric variables, sample analysis period, econometric method, etc.). We also carry out different statistical tests and use alternative selection criteria in order to check whether our estimations are robust. Finally, we make recommendations for future hedonic studies as well as for upcoming metaanalyses of the green building premium.
