Gibt es einen wissenschaftlichen Konsens zur Wirtschaftlichkeit nachhaltiger Immobilien?

Abstract

There is a clear consensus among scientists and the larger public on the importance of buildings and the built environment in reducing carbon emissions and resource consumption. It is not clear, however, to what extent environmental and economic objectives are aligned, i.e. if sustainable and energy-efficient buildings generally also make for profitable investments. The present paper analyses 42 international studies on the profiftability of sustainable buildings using a metaanalysis framework and concludes that at least a moderate price and rental premium exsists. Despite signs of publication bias in the existing studies, i.e. positive results are more likely to be published than negative or inconclusive findings, commercial and residential real estate markets appear to consider sustainable construction and refurbishment an economically sound endeavour. It is worth noting that the feasibility of individual green investments depends, among others, on market mechanisms for sharing risks and rewards efficiently, for example through green leases or energy performance contracting.
