A study from two commercial real estate groups claims there is "no credible evidence" to support a proposal from outgoing Mayor Thomas Menino that would make it mandatory for building owners to report how much energy their properties use

The Greater Boston Real Estate Board (GBREB) and Building Owners and Managers Association (BOMA) make that claim in "An Economic Perspective on Building Labeling Policies," a report co-authored by Harvard University Environmental Economist Robert Stavins, that examines the extent to which mandatory building energy labeling helps reduce energy use.  

The industry groups’ study is in direct response to the city of Boston’s current proposal for mandated reporting for office buildings, apartments and condominiums.  

"Although BOMA and GBREB are committed to energy efficiency and many other measures intended to protect the environment, both organizations are opposed to policies that arbitrarily intervene with market forces, assign market value to buildings, stigmatize property or otherwise interfere with transactions," according to a statement from the two real estate industry groups.
