PROJECT PROFILE
GREEN ACRE GRANGE, DUNDRUM, DUBLIN
KERRIGAN MECHANICAL’S TURNKEY MECHANICAL PACKAGE COVERED ALL ELEMENTS FROM THE INSTALLATION OF 250KW GAS BOILERS TO THE FINAL CONNECTION OF KITCHEN SINKS, PASSIVE FIRE-RATED DUCTWORK AND SMOKE SHAFTS…. DELIVERING HOLISTIC ENERGY MANAGEMENT IN A PRESTIGIOUS DUBLIN DEVELOPMENT
Over the years, Kerrigan Mechanical has honed its expertise in district and communal heating schemes, becoming a specialist in its field. It was no surprise then, when the Co Meath business was contracted to complete a mechanical installation at Green Acre Grange. As lead coordinator on the project, Kerrigan Mechanical was also charged with managing all MEP sub-trades including electrical and sprinkler systems. The Green Acre Grange development consists of 307 units comprising one-, two- and three-bedroom apartments in three carefully arranged and designed blocks. Also included in the space are shared amenity spaces and services including a concierge, creche, gym, landscaped rooftop terraces, co- working spaces and meeting rooms.
Engineering consultant IN2’s NZEB- compliant energy strategy for the development uses a centrally-located air-source heat pump, supplemented with condensing gas boilers. Each apartment includes a heat interface unit providing users with a meter reading of their individual heating and hot water usage. The heat recovery ventilation units provided for each apartment are highly efficient and temper incoming fresh air to both offset heating costs and reduce draughts from trickle vents. A tenth of all parking spaces feature electric vehicle charging stations, with a ducted connection run to the remainder to facilitate future connection. The scope of works included a comprehensive turnkey mechanical package covering all elements of mechanical services from the installation of
250kW gas boilers to the final connection of kitchen sinks as well as passive fire-rated ductwork and smoke shafts. SUSTAINABLE HEATING Innovative and environmentally conscious, the design of the project’s energy centre uses heat pumps as a primary heat source backed up by gas boilers. The heat pumps act as a pre-heat source for the gas boilers, reducing their workload and optimising their efficiency by drawing heat from renewable energy from the air. This approach not only reduces overall gas consumption, but also aligns with the client’s desire for renewable energy utilisation, contributing to environmental conservation and reducing the carbon footprint associated with energy consumption. Furthermore, the reduction in gas
“We were thrilled to have the opportunity to contribute our expertise to such a prestigious project in the heart of Dublin.”
