(b)new dwellings, in the form of target fabric performance values.

Primary energy consumption rates and fabric performance values

6.  After regulation 26, insert—

Primary energy consumption rates for new buildings

26A.  Where a building (other than a dwelling) is erected, it must not exceed the target primary energy consumption rate for the building which has been approved pursuant to regulation 25C(a).

Primary energy consumption rate and fabric performance values calculations

7.  After regulation 27 insert—

Primary energy consumption rate calculations

27A.(1) This regulation applies where a building (other than a dwelling) is erected and regulation 26A applies.

(2) Not later than the day before the work starts, the person carrying out the work must give the local authority a notice which specifies

(5) In this regulation, “specifications” means specifications used for the calculation of the primary energy consumption rate.

Fabric performance values calculations

27B.(1) This regulation applies where a dwelling is erected and regulation 26B applies.

(2) Not later than the day before the work starts, the person carrying out the work must give the local authority a notice which specifies

(c)a list of specifications to which the dwelling is to be constructed.

(3) Not later than five days after the work has been completed, the person carrying out the work must give the local authority

(a)a notice which specifies
