Schedule 5—High efficiency fan installations—static and total efficiency benchmarks

  For section 15 of this determination, and for equations 7 and 18 (section 31 of this determination and section 6 of Schedule 1), if the model of the ith­ fan:
 (a) is of an eligible fan type indicated in the table below; and
 (b) was tested using an installation category indicated in the table;
  the market average efficiency grade (Nave,i) and the high efficiency grade (NHE,i) of the fan are the corresponding values indicated in the table.

High efficiency fan installations:
