IEE EPISCOPE Project (2013-2016)
 EPISCOPE includes Pilot Actions in 16 Member States to track the
refurbishment of housing stocks (local and national)
 3 Questions:
– So, what proportion of the housing stock has been refurbished
to date?
– And, what proportion of dwellings are getting energy upgrade
works done each year?
– If we are going to miss 2020/ 2030 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. Lowest level for compilation of
statistics in line with data protection. Must nest within Electoral Divisions)
– 93 Electoral Divisions (smallest legally defined administrative areas in
the State for which Small Area Population Statistics are published from
the Census)

Wall Types* – panning in........
When you pan in, the range of wall types in each small area is shown
21
Wall Insulation (U Values)
The U value band map is a “Current Status” indicator!
We need to see the map changing to yellow and
green in the future.
22
Roof Insulation (U Values)
Still so much to do! We need to see small areas shaded
(at least yellow but ideally) green / dark green

Fuel Poverty Map
Fuel Poverty Indicator is based on BER rating of E1, E2, F or
G and a Deprivation score of 8,9 or 10.

Fuel Poverty Map (2)
The Fuel Poverty Indicators can be
altered based on a range of criteria
