As the topic of energy efficiency is still in the spotlight after a few decades of studies delving into it, several dozens of recent publications deal with the potential occurrence of a price premium for green buildings, namely, those significantly outperforming the best conventional ones.

In particular, we propose combining an application of the analytical hierarchy process and linear optimization to identify the role played by energy rating bands and the energy performance index in shaping property prices. As a result, we expect to estimate the likely magnitude of the price premium for building energy efficiency. We test the approach on the local housing market in Padua, North-eastern Italy. A strong influence is found to be exerted on property prices by the energy performance as expressed by the rating bands.

Abstract

As the topic of energy efficiency is still in the spotlight after a few decades of studies delving into it, several dozens of recent publications deal with the potential occurrence of a price premium for green buildings, namely, those significantly outperforming the best conventional ones. Almost all of those investigations find that a price premium indeed occurs and is statistically significant - though its magnitude is still debated - using regression analysis. Especially, the traditional hedonic price model is widely used in early studies, while the spatial autoregressive and spatial error models are ever extensively employed in the newest ones. Here we suggest using a different approach by turning to multicriteria analysis. In particular, we propose combining an application of the analytical hierarchy process and linear optimization to identify the role played by energy rating bands and the energy performance index in shaping property prices. As a result, we expect to estimate the likely magnitude of the price premium for building energy efficiency. We test the approach on the local housing market in Padua, North-eastern Italy. A strong influence is found to be exerted on property prices by the energy performance as expressed by the rating bands. After discussing the empirical findings and the limitations of the analytical procedure, we also outline further developments for our multi-criteria approach.
