RENOWIKI Ireland

Retrofit of a semi-detached 1960 two-storey dwelling house to full certified Passive House standard. Designed space heat demand is 15kWh/m2a but monitored space heat demand in the first year of occupancy is less than 9kWh/m2a. The project is an exemplar for the retrofit of Ireland’s 1.6million existing legacy dwellings which have an average primary energy demand of 273kWh/m2a.

Project proves that a 97% energy demand reduction is possible and affordable.

Retrofit included full linear thermal bridge assessment in 2D and 3D informing the optimisation of all architectural details. All junctions were also assessed for surface temperature compliance (fRsi > 0.75).

Free interactive whiteboard resources and photocopiable masters/worksheets on energy and energy efficiency developed by SEAI for primary school teachers.

This Standard Recommendation was developed to provide guidance on the energy efficient retrofit of dwellings. Technical guidance is provided on the energy efficient retrofit of dwellings having particular regard to fabric and building services, the application of retrofit measures on a whole dwelling basis, general building science and the management of retrofit projects in respect of dwellings.
