YOUNG DESIGN BUILDPassive House Design & Build Energy Efficient School Buildings

Client: Holy Rosary Primary School

Location: Old Court Avenue, Ballycragh, Dublin 24. The existing school currently has more pre-fabricated temporary classrooms than permanent classrooms.

Client Brief: The brief was to provide three permanent classrooms for 75 students and staff to a high energy efficient standard with low maintenance requirements.

Outcome: Young Design Build adopted the Passiv Haus standard for the project and successfully delivered a state of the art building which centred on providing a conducive learning environment for the schools students. This was achieved by surpassing current building standards using proven green building practices and the following building principles: • ExternalEnvelope:Highlyinsulatedfloorslab,externalwalls& roof providing u-values less than 0.15 (current building standards require a u-value of 0.27). • WindowSystem:Tripleglazedaluminiumcladtimberwindows with an overall u-value less than 0.90 (current systems have u-values in the region of 1.1 to 1.4). • AirTightness:Oftenoverlookedinnewbuildings,butair tightnessiscurcialtokeepingthewarmthinsideandthecold outside maximising the benefits of solar gain. This is achieved using high quality air tightness products which are carefully installed to ensure their effectiveness. • MechanicalVentilation:Asthebuildingenvelopeiscompletely air tight the air inside the classrooms needs to be changed using HeatRecoveryVentilation.Staleairisextractedusinglowvoltage fans within a complex unit which recovers the latent heat and transfers it to the fresh filtered air being delivered into the classrooms. • Flooring:APolishedconcretefloorhasbeenusedtoprovidea maintanence free flooring solution within the classroom.

All of these components when successfully delivered provide the perfect environment for children to learn. As fresh pollen free air is continually being provided within the classrooms; CO2 levels are brought to a level where fatigue is eliminated; reducing one of the main reasons classrooms can become disruptive. Other areas of expertise which Young Design Build can help your school include:

Rainwater Harvesting: Rainwater is recovered from the roof and contained for use within the classroom toilets reducing the amount of water being used which will reduce the cost of water charges due to be implemented in the near future.
