This ambitious restoration is breathing new life into a Westport institution
About the project
IN2 was appointed by Inishoo Management Ltd. to provide full M&E and Sustainability Design for the Coach House at Westport Estate in County Mayo. The ambitious restoration project, which focussed on creating a new visitor experience in the Coach House, includes large-scale refurbishment of the Coach House as a whole, as well a new extension. Refurbishment also extended to Westport House itself, as well as the surrounding gardens, promising a “a unique Irish landscape experience”.
Whilst the whole estate underwent a major transformation, IN2 was involved only in the refurbishment of the two storey Coach House. Offering engineering expertise in energy conservation, ventilation, solar gain, and overheating analysis, IN2 designed energy models that complied with the requirements of TGD Part L 2022.
As part of the proposed building design, thermal analysis was undertaken as part of a feasibility study for the building using Dynamic Simulation Modelling (Tas software). The building model was then simulated against representational climate data on an hour-by[1]hour basis, thereby predicting solar gain throughout the summer. The analysis found all spaces to full comply with industry regulations.
IN2 also conducted Overheating Analysis in line with TGD Part L 2022 of the Building Regulations, as all naturally ventilated buildings require compliance with CIBSE TM52. The CIBSE TM52 methodology is a comprehensive thermal comfort assessment that checks summertime hours, peak day and peak hour. The CIBSE TM52 assessment was undertaken and all occupied spaces are predicted to provide adaptive comfort in full compliance with TM52.
Finally, IN2 conducted a comprehensive compliance check in accordance to the Technical Guidance Document Part L 2022. This required assessments of the Air Source Heat Pump, the roof insulation of the Coach House, and the addition of 142m2 of PV to the roof of the café, amongst others.
