This article analyses the “labor” of financialisation in respect to the regulation of the commercial real estate industry, which has been transformed since the 1990s given the use by corporate investors of capital, representations and techniques from market finance. Based on research on environmental policy promoting energy efficiency in property in France, it shows how these investors, altogether with their associated experts, engage in joint regulation with policymakers. Thanks to their dominant position in the policymaking process, these actors from the financialised real estate industry have attempted to adjust the rules to make them compatible with their accumulation practices. Despite the fact that other building owners defended different positions, they eventually managed to circulate their financialised data, representations and techniques towards policymakers throughout power struggles.
