Annual energy spend of homeowners circa. €3.4 billion

Circa. 700,000 homes on oil, 570,000 on gas, remainder mostly on electricity, solid fuels

Irish homes use 7% more energy than EU average but emit 58% more CO2 due to our fuel mix

Residential energy demand and emissions

A quarter of all energy used in Ireland is

consumed directly in homes. Second

only to transport, and more than is used

by industry.

For 2017 we estimate that

• 59% was for space heating

• 20% for water heating

• 8% for lighting & appliances

• 2% for cooking.

24% of energy-related CO2 emissions in

2017 (9.7 Mt CO2)

Second largest source of CO2 emissions

after transport (which accounted for

39%), and was ahead of industry.

Energy related CO2 per dwelling

Over 300 community projects have

received over €125 million in funding

New build dwellings are 70% more

efficient than those built in 2005

SEAI priorities

Moving from demonstration to mainstream:

• Alternative options for housing retrofit finance

• Targeted approaches (e.g. area-based

aggregation; public and approved housing stock)

• Minimum performance regulation

• Targeted communications - key decision points

• Skills and construction - standards, regulation

and compliance
