CHEEVERSCOURT&HALIDAYHOUSE, DÚNLAOGHAIRE
ON TIME AND ON BUDGET, KERRIGAN MECHANICAL OVERCOME COVID-19 CHALLENGES TO HAND OVER TWO DEVELOPMENTS WITHIN 17 MONTHS… KERRIGAN MECHANICAL DELIVERS ANOTHER TRAILBLAZING NZEB SCHEME
K errigan Mechanical has successfully handed over its state-of-the-art district heating schemes for Cosgrave Developments’ nZEB apartment schemes in Dún Laoghaire. Commercial heating experts, Kerrigan Mechanical worked simultaneously on sister blocks Cheevers Court and Haliday House to install all mechanical works on time and within budget. Consisting of 368 apartments, two gyms, concierge and two common areas, these developments each feature an independent district energy centre and meter reading system. The move to Nearly Zero Energy Buildings (nZEB) is part of the climate action plan aimed to help us achieve our target Carbon
reductions and ultimately achieve Net Zero by 2050. nZEB describes buildings that have a very high energy performance in which the nearly zero or very low amount of energy required should be covered to a very significant extent by energy from renewable sources, which are produced on-site or nearby. COMPLIANCE Kerrigan Mechanical was able to achieve nZEB compliance by installing renewable sources of energy in its primary plant room. The energy centre consists of one Hamworthy ModuMax Boiler, three Daikin Heat Pumps and three DACHs micro CHPs.
The other notable mechanical works included fire fighting dry risers, passive fire-rated ventilation and air conditioning to the gym. “All apartments are equipped with a Danfoss Heat Interface Unit, which provides each tenant with instantaneous heating and hot water,” said Adam Dent, Contracts Manager at Kerrigan Mechanical. “Each dwelling also includes a Vent-Axia Heat Recovery Ventilation unit, which, together with the other components, complement each other and thus are the perfect solution for an A-rated apartment.” Challenges on this project included the out break of Covid-19. “We had to rethink our install methods, splitting manpower
