reg 27A Fabric energy efficiency rate calculations
(1) This regulation applies where a dwelling is erected and regulation 26A applies. (2) The person carrying out the work must— (a) where the dwelling is within a higher-risk building, ensure the application for building control approval in relation to the work is accompanied by a notice which specifies— (i) the target fabric energy efficiency rate for the dwelling, calculated and expressed in accordance with the methodology approved pursuant to regulation 24, (ii) the fabric energy efficiency rate for the dwelling as designed, calculated and expressed in accordance with the methodology approved pursuant to regulation 24, and (iii) a list of specifications to which the dwelling is to be constructed; (b) in any other case, not later than the day before the work starts, give the building control authority a notice which specifies the matters set out in paragraphs (i) to (iii) of sub-paragraph (a). (3) The person carrying out the work must— (a) where the dwelling is within a higher-risk building, ensure the application for a completion certificate in relation to the work is accompanied by— (i) a notice which specifies— (aa) the target fabric energy efficiency rate for the dwelling, calculated and expressed in accordance with the methodology approved pursuant to regulation 24, (bb) the fabric energy efficiency rate for the dwelling as constructed, calculated and expressed in accordance with the methodology approved pursuant to regulation 24, and (cc) whether the dwelling has been constructed in accordance with the list of specifications referred to in paragraph (2), and, if not, a list of any changes to those specifications; or (ii) a certificate of the sort referred to in paragraph (4) accompanied by the information referred to in sub-paragraphs (aa) to (cc) of paragraph (i); (b) in any other case, not later than five days after the work has been completed, give the building control authority a notice which specifies the matters mentioned in sub-paragraphs (aa) to (cc) of sub-paragraph (a)(i) or a certificate of the sort mentioned in sub-paragraph (a)(ii). (4) A building control authority is authorised to accept, as evidence that the requirements of regulation 26A have been satisfied, a certificate to that effect by an energy assessor who is accredited to produce energy performance certificates for that category of building. (4A) Where the regulator is the building control authority by virtue of section 91ZB of the Act (the regulator: building control authority for other work), it must send a copy of each notice or certificate it receives under this regulation in relation to a building to the local authority for the area in which the building is situated. (5) In this Regulation, “specifications” means specifications used for the calculation of the fabric energy efficiency rate.
