Middlemore Hospital Heat Pump Integration Project

Middlemore Hospital has identified an opportunity to install high-temperature water-source heat pumps to recover waste heat from the hospital’s chiller condenser water circuit (~25 °C) and provide useful heating for the heating hot water circuit (~80 °C). This will offset the load on the natural gas-fired hot water boilers, reducing natural gas use and associated emissions and reducing net energy costs for the hospital.

This project concept has already been investigated to a preliminary level, and proposals for a design and build scope are now sought from suitable parties to deliver this project.

This project will involve new high-temperature heat pump(s) with a total heat output of roughly 1,400 kW, tie-ins to existing infrastructure for electric power, condenser water piping and heating hot water piping, and all associated connections, instruments and controls to allow the system to function safely and as intended.

This procurement relates to​​ the Design, Build, procurement, construction, commissioning and hand-over required for the integration of a new high-temperature heat pump system at Middlemore Hospital. This system will integrate with the existing hospital electrical, condenser water and heating hot water systems. This scope is expected to cover all required aspects of this project. The respondent is to take responsibility for the project design in order to achieve the maximum possible energy savings and emissions reductions. Intellectual property for this design will remain the property of Te Whatu Ora - Counties Manukau.

This is a multidisciplinary, brownfield integration project that requires detailed design by suitably experienced and qualified engineers and designers. Safety considerations for the construction, commissioning and operation of these heat pumps and related systems will need to be carefully planned, as this is a functioning hospital environment.

Te Whatu Ora - Counties Manukau requires a Fixed Price Lump-Sum Design and Build proposal to deliver a heat pump project that can provide savings as per the details mentioned in the attached RFP document.
