Jens Laustsen of Concerted Action speaks abut Deep Energy Renovation at the Deep Retrofit conference on 14th June 2018.

1. Deep Energy Renovation
a new challenge for the Concerted Action EPBD.
Jens Laustsen
Coordinator of CA EPBD
SEAI's 2nd Deep Retrofit Conference
Dublin, 14 June 2018

2. Concerted Action EPBD IV
Concerted Action EPBD IV:
• Started 1 October 2015 and run until October 2018
• All EU Member States plus Norway
• 29 partners – lead by DEA (DK)
• 4 CA plenary meetings
• November 2015 in Copenhagen
• May 2016 in Vilnius
• February 2017 in Valletta
• October 2017 in Bucharest
• 1 In depth workshop in Frankfurt in May 2018
• Experts meet and share experience
• Support implementation and maximise outcome of EPBD
• Confidentiality in meetings – Free and open
Lessons learned
and share of best
practice

3. The EPBD Recast
Major focus on
Energy Performance

4. Recast EPBD
High focus on New Construction
For new buildings there is a strong focus on performance
based building codes:
• Overall performance by construction
• Tightening requirements towards NZEBs in 2020
• NZEB in public buildings from 1 January 2019
• NZEB all buildings in 1 January 2021
• Certification of new buildings
• Cost optimality
• All MS have Energy Performance requirements for new
buildings
• Many have secondary requirements too
Especially based
on U–values

5. Requirements New Buildings- nZEB
Survey – filled in by half
of MS shows that 60 %
has defined nZEB
standards by April 2015.
Ways to calculate
instance RES are are
different !

6. Requirements New Buildings- nZEB
16 + 11 (around 80 %)

7. Cost Optimality
Large work has been done
on Cost Optimality – LCA’s
Levels and ways are are different !

8. Control for New Buildings
Most member states
do multiple checks
And use EPCs to
document compliance

9. Danish Building CodeskWhperm²peryear
In Danish action plans for a CO2 neutral society it is the target that all
building will be positive in the future (year still to be decided)

ventilation and hot sanitary water

10. • As of 2021 all new buildings must be NZEB
• Public Buildings already in 2019
• Most Member States are well on the way to
achieve NZEB levels in the new construction
But:
• Only around of Building Stock 1 % built every year
• Most European Buildings in 2030 are already built
• Even for 2050 a very large share is out there today !
New Buildings Conclusion

11. Existing Buildings
The largest challenge
is in existing buildings
If targets to be met:
We need NZEB
existing buildings

12. Existing Building Stock
• Most of existing European buildings were built long
before building codes approached NZEB levels
• These buildings have much higher consumption
• Need to address existing buildings
- And they have a much higher energy use

Existing Buildings
New Buildings / NZEB level
The
Big
Gap

13. Progress in Existing Building Stock
• Most European Countries have Renovation in level of
only 1 – 1 ½ % of Buildings stock per year
• Most of these renovations are only shallow on energy
• As new NZEBs are less than 10 % of building stock
today (a couple of per cent)
=> More than 90 % of building stock must be renovated
deeply or demolished before 2050
• This means that 3 % deep renovations per year is
needed !
• Or if in 2 steps 6 % needs to be done per year

14. EPBD Focus on Renovation
• Previous the EPBD had demand for policies such as:
• Certification
• Inspection
• Training
• Finance measures (vague)
• Information information (vague)
• Little focus on over all packages
• Important link to EED directive
Mainly handled
as individual
measures

15. Certification to Support Renovation
Demands for certification in article 11, 12 and 13 by:
• Construction
• By sale
• By lease
• Regular for public buildings
• Must include a recommendations for cost effective
or cost optimal measures
.
Available through all occupancy
Ready for use in a renovation project

16. Certification Systems
Germany
Diversity ! All countries have systems in place
But:
How to activate ?
Focus on quality

17. Finance and Incentives
Surveys on finance
and incentives

18. Need for change
• All MS have now experience with most of these
articles / systems
• They have systems in place and are not ready to
change too much
• Most experts will agree that there is no silver bullet
for existing buildings
• Need for more policy integration both in existing
and new buildings !
• CA EPBD already focused on Deep Renovation in
terms of sessions and open event in Vilnius

19. Need to Remove All Major Barriers
Imagine these are four different
barriers; economy, capacity,
information and legal issues

20. Need to Remove All Major Barriers
We remove one
– but the other 3 still remains !

23. RESIDENTIAL ENERGY EFFICIENCY
Lithuania key statistics:
• Population – approx. 3 million
• 66% of population lives in multi family buildings built
before 1993
(> 38,000 multi family buildings and > 800,000
apartments)
• 97% privately owned, only 3% municipal rental stock
• 65% of buildings supplied by district heating system
Problems:
• poor Soviet construction standards, little maintenance
– inefficient heating systems and engineering
equipment
– bad quality windows, roofs, intersections huge
energy losses
 most buildings in poor condition, lack of proper
management
> most of Lithuanian households are not satisfied
with their homes

24. PROGRAMME MODELS
Old model for housing modernisation in Lithuania
1. Home owners on their own initiative prepare investment projects,
take loans and implement modernisation
The main problems of this model:
- lack of homeowners initiative
- fear to take a loan
- Low trust on the results after renovation

25. 1. GOOD FOR HOME-OWNERS: GREATER
COMFORT, LOWER BILLS, ADDED VALUE
Experience from energy efficiency upgrading projects in multifamily
buildings shows the combination of measures:
- replacement of windows and external doors,
- insulation of external surfaces: roofs and walls,
- modernization of heating substations and balancing of heating
systems
reduce energy consumption about 50-70 %.

26. Revised / Amended Directive 2018
• Agreed in both EU Parliament and Minister Council
• Will move renovation strategies from EED to EPBD
directive
• This could mean more focus on actual implementation
• Better connection to other energy performance policies
• Directive also stress new points such as:
• One stop shops
• Multiple Benefits
• Energy Poverty
• Smart funding / structural funds

27. In-depth Workshop in Frankfurt
23rd-24th of May 2018
• One stream Focused on Deep Renovation
• Renovation strategies
• Deep energy renovation
• Data gaps
• Targets
• Smart finance
• Other benefits
• One stop shop

29. New CA EPBD
• A new CA EPBD has just started (May 2018)
• This will ensure continuous and increased collaboration
between Member States + Norway
• 6 plenary meetings planned over the next 48 months
• 2 In-depth workshops
• Further collaboration structures
• Increased collaborations with other CAs
• for EED, RES and Defence
• Also increased collaboration with finance such as EIB
• And with Smart Buildings / technologies

30. New CA structure
$

31. The new CA EPBD
• Will work increased Collaboration
• Especially with CA EED and CA RES
• But also with
• Finance
• EU projects (H2020)
• Other initiatives
• Stakeholders
• We need more best practice examples
• Solutions and policies which are documented to work
• Documentation of results and more data

32. Thank you
for your
attention
