Overview
This decarbonisation project, undertaken with McKeon Group as the Project Supervisor Construction Stage (PSCS), encompassed the installation of a high-temperature air-source heat pump at the UCD Energy Centre. This project was pivotal in the university’s ongoing strategy to reduce carbon emissions and enhance energy efficiency across the main Belfield Campus.
The Higher Education Authority (HEA) supported the installation of the heat pump with a Pathfinder grant in connection with the Sustainable Energy Authority of Ireland (SEAI).
The work at the UCD Energy Centre marks a leading energy Pathfinder project for the entire third-level sector in Ireland, and the resulting energy performance of the systems will be closely monitored to assist future decision-making in the sector.
The Challenge
UCD’s district heating system serves 16 buildings with a total floor area of 205,000 m². The district heating system is supplied by the Energy Centre, which contains two high-efficiency CHP engines, two 1.75MW gas boilers, a 0.92MW biomass boiler and a 5.2MW backup gas-fired boiler.
With an eye towards the upcoming 2030 public sector energy and carbon reduction targets, UCD aimed to embark on a phased approach to decarbonise its thermal energy infrastructure, with installing the heat pump marking a strategic first step.
The Delivery
UCD enlisted McKeon Group’s expertise to deliver this significant decarbonisation project. Our comprehensive solution involved meticulous planning and execution at every stage of the installation process. Close collaboration with equipment suppliers and manufacturers ensured seamless integration of the specialised heat pump system into the Energy Centre’s existing infrastructure.
The mechanical work undertaken was extensive, encompassing a range of tasks essential for successfully installing the heat pump. This included craneage, offloading, and installation of the heat pump equipment, which comprised six large sections and ancillary items such as interconnecting pipe spools and control panels.
Furthermore, modifications to the existing Energy Centre’s heating pipework were necessary to accommodate the new heat pump and allow for potential future installations. Installing a new heat meter facilitated monitoring heat pump energy output for reporting purposes while flushing, and water treatment ensured optimal system performance.
Simultaneously, our team addressed the electrical and BMS scopes of work. The existing LV panel was modified to provide the necessary power supplies for the heat pumps and to interconnect the power and control cabling. This facilitated seamless integration with the heat pump vendor-supplied control panel and inverters, the pump, the BMS control panel and the active harmonic filters.
The implementation of a new BMS outstation enables monitoring and control of the heat pump and associated sensors, further enhancing system efficiency and performance.
The Outcome
The successful implementation of the heat pump installation marked a significant milestone in UCD’s journey towards decarbonisation and sustainability.
This pioneering project, supported by grants from the Higher Education Authority (HEA) and Sustainable Energy Ireland, was a trailblazing endeavour within the Irish higher education sector. The resulting energy performance of the systems is closely monitored to inform future decision-making and to help achieve a minimum Building Energy Rating (BER) of B2 across all UCD campus buildings by 2030.
Through meticulous planning, technical expertise, and unwavering commitment, UCD and McKeon Group have demonstrated the transformative potential of sustainable infrastructure development within academic institutions.
