Boston has adopted one of the most ambitious carbon reduction regulations for large buildings in the country, the Building Emissions Reduction and Disclosure Ordinance or BERDO 2.0. The policy will require all large buildings in Boston to significantly lower their greenhouse gas emissions (GHG) to zero carbon levels of performance by 2050. The policy development process for BERDO 2.0 involved the work of a significant number of stakeholders, community members, technical experts, and data driven expertise over a two year period. This session will explore the policy development process for BERDO 2.0. In this presentation, panelists will discuss how the City of Boston worked to center the voices of disinvested communities and engage industry stakeholders in the development of BERDO 2.0. Synapse Energy Economics performed an in-depth building energy analysis to develop policy recommendations (including emission targets by building type and compliance strategies) and to assess cost-effective pathways to meeting the city's mandatory GHG targets. Synapse will discuss these analyses and how it incorporated the views of various technical experts from the building science, architecture, engineering, green building consulting, renewable, and historical preservation industries. Synapse will further highlight how building energy benchmarking datasets were leveraged to inform the policy development for BERDO 2.0. The Institute for Market Transformation (IMT) is the leading national expert advocating for, developing, and implementing building performance standards such as BERDO 2.0. IMT strongly advocates for using building performance standards as a way to engage with community voices. IMT will discuss the ways in which community voices were centered in the development process for BERDO 2.0 creating a more inclusionary building performance standard.
