Ireland’s First Certified Retrofit of a Building to a Super-low Energy Standard

Published: Thursday, January 10, 2013

 

 

The super low energy standard in question is ‘EnerPHit’, the retrofit version of the ‘Passive House’ Standard. This project by Joseph Little Architects in Monkstown, Co. Dublin resulted in a reduction of 90% in its BER (using DEAP) and results in an annual specific space heating demand of 17 kWh/(m2a) according to PHPP (the Passive House software), see attached certificate. The house also has a low carbon focus in its material specification (featuring timber frame, cellulose, woodfibre EWI etc.) and has an innovative, indoors, gravity fed rainwater harvesting system. The services feature a Paul MVHR system with post-heating facility and a 3.9-24 kW modulating boiler (which should never need to output more than 10 kW). There are only three wall-mounted convector heaters and two towel rads. Orientation, glazing ratios, sun pipes and rooflights ensure the house is lit evenly. The combination of even surface temperatures and good ventilation and light make it a comfortable, healthy place to be, and requires almost no heating in Winter.
