EPISCOPE/ TABULA Irish Building Typology
• 3 new dwelling types• 31 existing dwelling types• standard and advanced upgrade analysis for all existing dwellings
1. So, what proportion of the housing stock has been refurbished to date?
2. And, what proportion of dwellings are getting energy upgrade works done each year? How are we tracking?
3. If we are going to miss 2020/ 2030/2050 targets, what policy steps or interventions can be taken to close the gap?

EPISCOPE Pilot Action: Northside of Dublin City
Pilot Action Area data:
– Population: 307,000
– 134,000 dwellings
– 1,242 Small Areas (50-200 dwellings)
– 93 Electoral Divisions (smallest legally defined administrative areas in the State for Small Area Population Statistics)

I propose to show this graph as part of the next slide. The graph is related to the text in slide 10. There is no time to appreciate all the figures in the graph and the concept is more important.

Base assumptions for ‘business as usual’ Trend Scenario
Achieving 80% reduction by 2050 will require:
DEEP retrofit of 75% of the residential stock (i.e. to primary energy value of circa 43 kWh/m2/year)
A 60% de-carbonisation of the electricity grid
Recommendation
Assuming 75% of residential stock of 1.6m dwellings will require a deep retrofit at c €30k per unit, €36bn spend on dwellings to hit 2050 target
Scottish HCS 3,000 building surveys per year €1m p.a.
English HCS13,300 social surveys/ 6,200
building surveys/ inspections p.a.€3.75m p.a.
Northern Irish HCS1,314 social surveys/ 1,434
building surveys (every 5 years, 2011/ 2016)
€0.4m
Given the scale of the task to meet 2020/ 2030/ 2050 energy saving targets, a rolling residential energy performance survey for Ireland is STRONGLY RECOMMENDED
