This project consisted of the construction of a 2 storey extension to existing primary school at St Marys National School in Enfield, Co. Meath, This included link corridors at ground and first floor comprising of 8No-Classrooms, support teaching spaces and ancillary accommodation with a total floor area of c. 1556sqm. The site works to the school grounds involved of the provision of ball court, gardens & landscaping and boundary treatments. The works to the remainder of the site consisted of the provision of 8 No additional car parking spaces including 3No disabled parking bays and a revised drop-off and pick-up facilities to the existing entrance of the school.
In July 2013, the Department of Education and Skills prioritised funding to facilitate the construction of schools in rapidly developing areas such as Enfield, Co. Meath. St Mary’s school, Enfield original build was completed in 2012 and the programme was tendered on a design and build basis for the new 8 classroom extension with GP hall. It was intended that the school would be operational by the start of the school term in September 2014/15. The timescale was designed to allow an appropriate period in which a planning decision could be made while facilitating a proposed commencement date of December 2013. Construction of the school was completed within a 32-week programme.
In accordance with the Department of Education and Skills school specification, the building was constructed to facilitate a passive environment entailing light sensitive light fittings, excellent natural daylight, natural ventilation, air infiltration and water efficiency.
The requirements set out in the Department’s TGD documents for air-tightness required an air loss of 3m3/h/m2 at a test pressure of 50Pa. The actual results from the test surpassed the minimum requirements. This was down to the quality of installation and construction of all building elements. A Tyvek breather membrane was installed throughout to give the building excellent air-tightness. Energy conservation was conveyed through thermal performance & air tightness requirements which when constructed surpassed part L requirements.
A building energy rating certificate and advisory report formed part of the original TGD documents. It is accompanied by a CO2 emissions indicator. The Building energy rating survey was carried out in July 2014 which resulted in the building receiving a highly sustainable building energy rating band of A3.
