Unlike residential buildings, large public buildings with more than 20,000 square meters of gross floor area are required to meet the green building standards starting in early 2014, regardless of when they were built.
Hindi tulad ng mga gusali residential, malaking pampublikong gusali na may higit sa 20,000 metro kwadrado ng gross floor area ay kinakailangan upang matugunan ang mga pamantayan ng berdeng gusali na nagsisimula sa unang bahagi ng 2014, nang walang kinalaman sa kung kailan na-built.
