An ambitious decarbonization strategy made a reality

About the project

Ushering in the Mater Misericordiae University Hospital’s (MMUH) ambitious decarbonisation roadmap, IN2 were appointed to provide full M&E services for the leading healthcare facility which is housed in a 18050 Victorian building. The project, which included the development of a comprehensive Energy and Infrastructure Feasibility Study, aimed at a 6.3 GWh annual gas reduction and 2,500 tonnes of CO₂ savings per year, aligns with Ireland’s Climate Action Plan 2030 and the Government’s Climate Action Plan 2025 objectives.

IN2 aimed and assisted MMUH on the delivery the Hospital’s strategic objectives in relation to Climate Action and Sustainability and were responsible for the study which involved assessing the electrical and thermal infrastructure across the entire Mater campus. This involved detailed load assessments, energy modelling and the development of decarbonisation scenarios designed to balance technical feasibility, cost and operational impact.

A review of the existing combined heat and power, and boiler and medium-voltage systems was necessary, as well as preparing a decarbonisation roadmap signed with the Climate Action Plan. This translated into replacing gas-powered systems for air source and water source heat pumps that are supported by a new Central Energy Centre. This transition was aided by submitting an ESB Networks NC3 application to increase the hospital’s Maximum Import Capacity (MIC) from 3.8 MVA to 14 MVA and implementing dynamic energy simulations and carbon forecasting.

IN2’s delivery to this project has ensured that MMUH’s energy strategy provides a robust, data-driven framework for decarbonising one of Ireland’s biggest and most complex healthcare campuses. Through this work, IN2 has delivered a detailed roadmap that balances environmental ambition with clinical reliability and financial viability - and has shown how historic buildings can achieve net zero.
