; and (2) consider the specific challenges of enabling greater interaction between components of— (A) small- and medium-sized buildings and the electric grid; and (B) residential and commercial buildings and the electric grid. (c) Buildings-to-Grid integration report Not later than one year after the enactment of the Grid Modernization Research and Development Act of 2019, the Secretary shall submit to the Committee on Science, Space, and Technology of the House of Representatives and the Committee on Energy and Natural Resources of the Senate a report on the results of a study that examines the research, development, and demonstration opportunities, challenges, and standards needed to enable components of commercial and residential buildings to serve as dynamic energy loads on and resources for the electric grid. (1) Report requirements The report shall include— (A) an assessment of the technologies needed to enable building components as dynamic loads on and resources for the electric grid, including how such technologies can be— (i) incorporated into new commercial and residential buildings; and (ii) retrofitted in older buildings; (B) guidelines for the design of new buildings and building components to enable modern grid interactivity and improve energy efficiency; (C) an assessment of barriers to the adoption by building owners of advanced technologies enabling greater integration of building components onto the electric grid
