How can we upgrade residential buildings in Ireland?
A high proportion of the residential building stock in Ireland is pre-1996 construction (60% of Irish dwellings, which as of the 2006 census was approx. 1,000,000 dwellings). These dwellings were built before there were building energy performance standards in Ireland. There are ways to achieve energy savings through refurbishment of these houses, i.e., implementation of a package of measures for upgrade of the buildings’ thermal envelopes and heating systems.
For example, 1970s hollow block built homes with Building Energy Ratings (BERs) of D1, could be upgraded to B1 status through a combination of upgrading measures for the roofs, walls, windows and space heating efficiency.
To see what measures you might consider for your own house, download the TABULA_Typology Brochure from EnergyAction and look under your house type, construction method and year of construction. Take a look at the type of measures suggested, and discuss them with your architect or builder. The brochure was published in 2012, so building standards and prices have changed since then!
Where did this information come from?
The EU supported Tabula Project (see http://episcope.eu/index.php?id=97), which ran between 2009 and 2011, characterised energy properties of buildings. The Tabula Project developed a national building typology for each participating country. The data for Ireland (based on the 2006 National Census) below was extracted from the project website country pages – it shows the number of building types and year span of construction.
