Part B2 Heated Water Services (Verification Methods)

VERIFICATION METHODS

BV2.1

Compliance with BP2.1 to BP2.5 is verified either—

(a)

by calculation and certification by persons or organisations with recognised credentials in the design or testing of heated water service systems; or

(b)

by satisfying the required criteria when tested in accordance with a specified test method endorsed by a recognised certification body.

BV2.2

(a)

Compliance with BP2.8(b) for a heater in a heated water supply system is verified when the annual greenhouse gas intensity of the water heater does not exceed 100 g CO2-e/MJ of thermal energy load determined in accordance with AS/NZS 4234.

(b)

The annual greenhouse gas intensity of the water heater in (a) is the sum of the annual greenhouse gas emissions from each energy source in g CO2-e divided by the annual thermal energy load of the water heater.

(c)

The annual greenhouse gas emissions from each energy source in (b) is the product of—

(i)

the annual amount of energy consumed from that energy source; and

(ii)

the emission factor of—

(A)

if the energy source is electricity, 272 g CO2-e/MJ; or

(B)

if the energy source is liquified petroleum gas, 65 g CO2-e/MJ; or

(C)

if the energy source is natural gas, 61 g CO2-e/MJ; or

(D)

if the energy source is wood or biomass, 4 g CO2-e/MJ.

Explanatory information

Explanatory information:

In BV2.2 the symbol "g CO2-e/MJ" means "grams of Carbon Dioxide equivalent per megajoule/s".
