Name of Project: St. Mary's National School, Enfield

Client: DoES



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.
