Tearing down the information barrier: the price impacts of energy efficiency ratings for buildings in the German rental market
Improving the energy efficiency levels of the housing stock is of particular concern in the private rentalmarket where capital costs and utility cost savings are not shared in equal measure by landlords and tenants.
This problem is particularly pronounced in the German housing market with its predominance of rented
accommodation over owner occupancy. The present study is the largest to date to investigate the effect of
energy efficiency ratings on rental values. Using a semiparametric hedonic model and an empirical sample
of nearly 760 thousand observations across 403 local markets in Germany with full hedonic characteristics,
we find evidence that energy-efficient rental units are rented at a premium. However, this effect is not
confirmed for the largest metropolitan housing markets. In a second step, a survival hazard model is
estimated to study the impact of the energy ratings on time-on-market. It is found that energy inefficient
dwelling have longer marketing periods and are hence less liquid than their more energy efficient
counterparts.European Commission Horizon 2020 Grant H2020-EE-2014-201

Interpretable machine learning for real estate market analysis
While Machine Learning (ML) excels at predictive tasks, its inferential capacity is limited due
to its complex non-parametric structure. This paper aims to elucidate the analytical behavior
of ML through Interpretable Machine Learning (IML) in a real estate context. Using a hedonic
ML approach to predict unit-level residential rents for Frankfurt, Germany, we apply a set of
model-agnostic interpretation methods to decompose the rental value drivers and plot their
trajectories over time. Living area and building age are the strongest predictors of rent,
followed by proximity to CBD and neighborhood amenities. Our approach is able to detect the
critical distances to these centers beyond which rents tend to decline more rapidly. Conversely,
close proximity to hospitality facilities as well as public transport is associated with rental
discounts. Overall, our results suggest that IML methods provide insights into algorithmic
decision-making by illustrating the relative importance of hedonic variables and their
relationship with rental prices in a dynamic perspective
