controls, and instantaneous domestic hot water through plate heat exchangers. Smart variable speed water booster sets were installed with advanced control features such as automatic lead pump rotation, fault logging and soft pressure build-up to prevent water hammer. Mechanical ventilation with heat recovery (MVHR) systems supply fresh air and extract stale air from wet rooms, contributing to high thermal comfort, excellent indoor air quality and minimal energy waste at apartment level. The units include user-friendly commissioning tools, humidity-based control logic and tool-free maintenance access. The Micro-CHP unit is ErP A+++ rated, delivering a total efficiency of over 104%, with a minimum electrical efficiency of 28.4% and thermal efficiency of 75.5%. Multiple air-to-water heat pumps, rated ErP A++, achieves a seasonal coefficient of performance of 3.5 at 55°C, as tested to EN16147. MVHR systems recover up to 90% of heat from exhaust air, significantly reducing heating demand. Energy metering systems are compliant with EN1434 Class 2 for accurate monitoring, and condensing gas boilers operate at 91.4% efficiency with low NOx emissions under 48 mg/kWh. The entire system is monitored and controlled via a McCools building
management system (BMS) to ensure optimal efficiency and comfort across the development. Domestic water and heating services are carefully zoned, balanced and metered, with digital monitoring capabilities linked back to the BMS for performance tracking and maintenance. Additional systems delivered across the development included acoustic soils and waste systems, cold and boosted cold water services, mains water, sanitary fittings and a complete gas distribution network from external mains to plantroom. Notable safety features include jet fans installed in the basement level to circulate air, which ramp up with two extract fans to remove smoke in the event of a fire. M&P Mechanical carried out full testing and commissioning of all systems, including pressure testing, performance verification and seasonal commissioning over two years post- handover. Comprehensive operation and maintenance manuals, as-installed drawings and client training were provided to ensure smooth facility operation. M&P Mechanical worked closely with Walls Construction, Irish Water, Gas Networks Ireland and Marlet Property Group throughout the project to ensure
alignment on design, implementation and performance goals. Coordination meetings, BIM-based modelling using AutoCAD drawings and co-developed builders’ works drawings ensured efficient integration with other disciplines on site. Darren O’Neill, Project Manager, says, “This collaborative approach fostered a strong partnership, enabling the successful delivery of an efficient, reliable heating solution tailored to the needs of the residents and stakeholders. “Claremont Howth represents a forward- thinking, well-integrated district heating solution that combines sustainability, technology, and scale - making it a standout example in modern residential energy infrastructure. “The project demonstrates M&P Mechanical’s expertise in delivering high-performance, large-scale residential
mechanical installations that meet both technical and environmental benchmarks.”
