(B) Incorporation of changes On receipt of the proposed changes, the voluntary building energy code or standard developer shall have an additional 270 days to accept or reject the proposed changes of the Secretary to the voluntary building energy code or standard for the Secretary to make a final determination. (e) Administration In carrying out this section, the Secretary shall— (1) publish notice of consensus-based targets and supporting analysis and determinations under this section in the Federal Register to provide an explanation of and the basis for such actions, including any supporting modeling, data, assumptions, protocols, and cost-benefit analysis, including return on investment; and (2) provide an opportunity for public comment on proposed consensus-based targets and supporting analysis and determinations under this section. (f) Definition of economically justified As used in this section, in determining whether a voluntary building energy code established under section 304 or an updated voluntary building energy code under this section is economically justified, the Secretary shall, after receiving views and comments furnished with respect to a proposed voluntary building code or an updated voluntary building energy code, determine whether the benefits of the building energy code exceed its burdens by, to the greatest extent practicable, considering— (1) the economic impact of the building energy code on the manufacturers and on the home or building owners subject to such code; (2) the savings in operating costs throughout the estimated average life of the building compared to any increase in the price of, or in the initial charges for, or maintenance expenses of, the covered buildings which are likely to result from the imposition of the building energy code
