Target carbon dioxide emission rate
New buildings and certain extensions must be designed and constructed to not exceed a calculated target carbon dioxide emission rate, determined using a national calculation methodology.
Without prejudice to the requirements of regulation 39, where a building is to be erected, or a building other than a dwelling is extended as described in regulation 38(3)(b), minimum energy performance requirements in the form of a target carbon dioxide emission rate for that building shall be calculated using a national calculation methodology. The building, or extension as described in regulation 38(3)(b), shall be so designed and constructed as not to exceed its calculated target carbon dioxide emission rate with all carbon dioxide emission rates calculated and expressed using a national calculation methodology.
