Specification JVa Additional requirements

Specification JVa Additional requirements

ACT Appendix

1. Scope

This Specification contains requirements that must be complied with in addition to the modelling requirements of JV1, JV2 and JV3.

Intent

To clarify that there are additional requirements to the modelling under JV1, JV2 or JV3 that must be carried out.

2. Additional requirements — general

In addition to the modelling requirements for JV1, JV2 and JV3, a building must comply with—

(a)

for general thermal construction, J1.2; and

(b)

for floor edge insulation, J1.6(b) and J1.6(c); and

(c)

for building sealing, JV4 or J3; and

(d)

for deactivation, control and insulation of air-conditioning and mechanical ventilation systems—

(i)

J5.2(a)(i); and

(ii)

J5.2(a)(ii)(A); and

(iii)

J5.2(a)(iv); and

(iv)

J5.2(a)(vi); and

(v)

J5.2(b); and

(vi)

J5.2(c); and

(vii)

J5.3(b); and

(viii)

J5.3(d); and

(ix)

J5.5; and

(x)

J5.6; and

(xi)

J5.8; and

(e)

for testing package air-conditioning equipment not less than 65 kWr, AS/NZS 3823.1.2 at test condition T1; and

(f)

for testing a refrigeration chiller, AHRI 551/591; and

(g)

for interior artificial lighting and power control, J6.3; and

(h)

for interior decorative and display lighting, J6.4; and

(i)

for artificial lighting around the exterior of a building, J6.5; and

(j)

for boiling water and chilled water storage units, J6.6; and

(k)

for deactivation of swimming pool heating and pumping, J7.3(b)(ii) and J7.3(c); and

(l)

for deactivation of spa pool heating and pumping, J7.4(b)(ii) and J7.4(c); and

(m)

for facilities for energy monitoring, Part J8; and

(n)

for deactivation of fixed outdoor space heating appliances, clause J5.9(c).

Intent

To prescribe those Deemed-to-Satisfy Provisions and referenced documents that need to be complied with in addition to the modelling requirements of JV1, JV2 and JV3.

This clause lists requirements from the Deemed-to-Satisfy Provisions and referenced documents which must be complied with in addition to the necessary modelling. This is to overcome limitations in the modelling process by ensuring buildings designed under JV1, JV2 and JV3 cover the same range of energy efficiency attributes as the Deemed-to-Satisfy Provisions. For example, the standard of installing insulation is covered in subclause 2(a) of Specification JVa because it is not specifically addressed through modelling alone.

3. Additional requirements — NABERS Energy for Offices

Where not included in the building energy simulation to satisfy JV1(a), compliance must be achieved with—

(a)

for a tenant supplementary heating and cooling system, J5.7; and

(b)

for carpark ventilation and lighting—

(i)

J5.3; and

(ii)

J5.4; and

(iii)

J6.2; and

(iv)

J6.3; and

(c)

for heating, cooling and ventilation equipment not covered by the NABERS Energy for Offices base building rating, Part J5; and

(d)

for artificial lighting not covered by the NABERS Energy for Offices base building rating, Part J6.

Intent

To prescribe those Deemed-to-Satisfy Provisions that need to be complied with in addition to the modelling requirements of JV1.

4. Additional requirements — Green Star

Where not included in the building energy simulation to satisfy JV2(a), compliance must be achieved with—

(a)

for heating, cooling and ventilation equipment outside the scope of the Green Star model, Part J5; and

(b)

for artificial lighting outside the scope of the Green Star model, Part J6.

Intent

To prescribe those Deemed-to-Satisfy Provisions that need to be complied with in addition to the modelling requirements of JV2.
