Description
The Verification Method H1/VM3 can be used for HVAC systems in commercial buildings. It contains requirements for:
- a) Air conditioning system controls, and
- b) Mechanical ventilation system controls, and
- c) Fans, and
- d) Ductwork insulation and sealing, and
- e) Pumps, and
- f) Pipework insulation, and
- g) Space heating, and
- h) Refrigerant chillers, and
- i) Unitary air conditioning equipment, and
- j) Heat rejection equipment, and
- k) Facilities for energy monitoring, and
- l) Maintenance access.
The Verification Method H1/VM3 is one option that provides a means of establishing compliance with the performance criteria in Building Code clause H1.3.6.
Scope
The Verification Method H1/VM3 does not include requirements for:
- a) HVAC systems that directly cool cold rooms or heat hot rooms (such as in a butcher’s shop, fruit storage rooms or in laboratories); or
- b) HVAC systems that maintain specialised conditions for equipment or processes, where this is the main purpose of the HVAC system.
For these, compliance may be demonstrated using an alternative solution.
