Description

H1 Energy Efficiency Verification Method H1/VM3 First Edition Amendment 1 provides a compliance pathway for meeting the energy efficiency performance requirements of Clause H1.3.6 of the New Zealand Building Code, specifically for HVAC systems in commercial buildings.

The scope of the document covers energy efficiency provisions for air conditioning and mechanical ventilation systems, including controls, fans, ductwork, pumps, pipework, space heating, chillers, unitary air conditioning equipment, heat rejection equipment, energy monitoring, and maintenance access.

It is suitable for use in commercial buildings where HVAC systems are a significant component of energy use.

The amendment introduces references to the Building Product Specifications for pump motor efficiency and includes minor amendments to improve clarity, correct formatting, and update cross-references and terminology.

Scope

This verification method can be used for the energy efficiency of HVAC systems in commercial buildings. It contains requirements for: 

  • a) air conditioning system controls; and
  • b) mechanical ventilation system controls; and
  • c) fans;
  • 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.

Items outside the scope of this document

This verification method 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.
