Key Challenge for SEAI
The requirement for large-scale and deeper retrofit within
our built environment in order to maximise energy
efficiencies

Vision & Policy
Associated challenges:
o development of appropriate technical solutions
o consumer awareness and adoption
o finance models

5. 5
Deep Retrofit Pilot Programme
• Multi annual pilot programme
2017 -2019
• €5m budget allocation 2018
• Residential market only

6. Guiding Principles
• Minimum A3 Building Energy Rating and uplift of 150 kWh/m2/yr
• Whole house solution with a fabric first philosophy
• Deployment of renewables - fossil fuels are not funded
• Demonstrate comfort and health benefits e.g. Indoor Air Quality

Deep Retrofit?

7. 7
Scheme changes to date
 50% support of energy capital costs
 Requirement for pre-2006 homes is removed (150 kWh/m2/yr)
 Air permeability ≤ 5 m3/m2/hr/
- Importance of pre-works airtightness plan
 5% project management + 2% design & BER + 1% bonus
(3m3/m2/hr)
 Additional milestone payment at 25% completion stage
- 25%, 50%, 90%, 100% (12 months post works)

Householder Motivations
What are the top 3 householder motivations for carrying out a deep retrofit?
“We used to have ice form on the inside of windows in the
north facing rooms”
2. To save money on my energy bills Financial
3. To reduce the impact of our household on
the environment
Environmental
1. To make my home ‘warmer and more cosy’ is
the biggest motivator (78%)
Comfort

21. 21
Householder Satisfaction
94%
Of respondents were ‘very happy’ with
the outcome of the deep retrofit works.
This is reflected in householder
comments about their finished works:
of householders are confident
in their ability to use their new
technology and controls.

34. Behavioural Economics
and Deep Retrofit
The importance of reducing complexity in consumer’s decision
making process
34

35. Thinking Fast and Slow
2+2 = ?
17*24 = ?
35
This is what processing complicated information feels
like…
Kwh/M^2, U-Values, C02 saved etc.

36. • Webpage containing a link to
the form that needs to be
completed
The Hassle Factor
• Clicking link brings directly to
form to complete
36
How much of a difference can one-click make?
Now imagine how much impact a
cumbersome application process could
have!

37. Designing the Deep Retrofit Program to Reduce Complexity for
Consumers
• Role of Project Manager
• Focus on A3 – clear goal
• Emphasis on training project
engineers to use more
familiar language
