4. To retrofit or build a new community?
“An Ideal setting for a Council estate.
This aerial picture of part of the
Cranford Road estate shows the neat
and airy spacing, with pleasant greens
between the rows of houses. Although
in complete contrast to the old town,
with its splendid examples of
Georgian architecture, this essential
development is probably as tasteful
as a Council estate can be”.
Local newspaper 1950

13. Through life emissions report release
Retrofit v demolition and new build
• Comparison analysed over 50 year period.
• Advanced retrofit compared with:
– Traditional and timber frame construction
– Building Regulations Part L 2010, Code 4 & ZCH 2016
• Emissions considered:
– Embodied energy associated with new and existing
materials (‘locked in’), construction processes
– The ‘in use’ emissions for heating and power

15. Through life emissions report key findings
• Advanced retrofitted homes have lower emissions
than a new home built to CfSH level 4 and ZCH 2016.
• Considering ‘all in’ costs for similar energy
performance:
– Advanced retrofit costs almost 40% less
– A saving of approx £53,000 per dwelling
• Around 20,000 UK homes are demolished every
year. If we retrofitted instead:
– 422,500 tCO2/year could be saved,
– Equivalent of 211,000 new homes.

16. Project Summary Report release
Other Key learning points and findings
• Advanced retrofit is expensive but brings significant
environmental, economic and social benefits over demolition
and new build.
• Scaling up retrofit regionally has potentially massive benefits.
• Understand the home, select correct whole house
strategy.
• Follow energy design hierarchy and use proven innovation for
more positive carbon value / abatement outcomes.
• Energy modelling and targets:
– rdSAP is inadequate to model true benefits of advanced
retrofit.
– kg/m2/yr or CO2/m2/yr makes a better target and gives
fairer comparison than % emissions reduction targets
against baseline.

17. Project Summary Report
Key learning points & findings cont’d…
• A community liaison officer is essential.
• Briefing residents on energy efficiency requires a
sustained campaign approach.
• Running cost savings of up to 60% post advanced
retrofit are possible (be circumspect on predictions
given to residents).
• Always evaluate the social, economic and
environmental aspects of the project.
• The construction industry needs to up skill and gain
knowledge to sell new services - but where is
customer demand?

18. Project Summary Report
Key learning points & findings cont’d…
• Continuity of air tightness and insulation is key – detailing!
• Ensure good Project Management
– sequencing of work, integration of trades and on-site
quality control.
• Beware the hidden costs of retrofit
– not only capital costs of work.
• ERDF / EU project management is very demanding.
• The Green deal won’t work for C80 advanced retrofit
• Improved resident comfort, well-being and satisfaction is
rewarding - Here’s what residents said…

19. Resident feedback:
“It’s like having a new home on the same plot of
land, they are so much warmer, before they were
so cold and damp, we even had mould growing.
It’s so much better now.”
“ I’ve been running on solar again all day today!”
“The bills are so much cheaper. Bearing in mind
what sort of winter we have had, I was really
surprised how much I’ve saved.”

23. Introduction and standards
• EcoHomes (obsolete EAM for new housing)
• Code for Sustainable Homes (current EAM)
• Interim report by Zero Carbon Hub (ZCH)
• Recommendations of the Zero Carbon Hub
(ZCH) task group final report - future standard
• Building Regulations 2010 (part L revision due
2013 and 2016 for compliance with ZCH)

Code 6

27. ZCH recommendations
• Interim report considered 70% energy
improvement
• Final ZCH report concluded not possible
in all cases Code 4 homes
• Government has pledged to adopt ZCH final report
findings in full through Building Regs by 2016 (further
consultation to follow)
• By 2016 ‘Zero carbon homes’ – new definition!
• First Wessex is currently working in partnership with
ZCH at Rowner, Gosport using TSB BPE funding.

28. ZCH recommendations cont’d…
• ZCH based on regulated emissions only
– Code 6 covering unregulated emissions defunct
– New standard overall is the equivalent of Code 5
• 3 steps to demonstrate ZCH compliance
First two steps based on carbon compliance also known as Fabric Energy Efficiency
Standards – FEES
– Step 1: Ensuring an energy efficient approach to
design.
– Step 2: Reducing CO2 emissions through low & zero
carbon technologies and local heat networks.
– Step 3: Mitigating remaining emissions through
allowable solutions (off site)

30. ZCH recommendations cont’d…
• Carbon compliance (steps 1 & 2) compared with
CfSH and Building Regs part L 2006
– Detached house = min 60% improvement
– Attached house = min 56% improvement
– Low rise apartment/flat = min 44% improvement
(approx 25% above Part L 2010)
– All above therefore Code 4 compliant
• % improvement seen as confusing therefore
move away (now an absolute as built limit
rather than predicted at the design stage)

31. ZCH recommendations cont’d…
• Carbon compliance can also be expressed in terms of
energy use
– Approx 46 kWh/m2/year (detached and semi detached)
– Approx 39 kWh/m2/year (mid terrace, flat / apartment)
– Note that passive house standard is 15 kWh/m2/year
• Anticipated 2016 Building Regulations ‘built’ performance
for carbon compliance on site
– 10 kg CO2(eq) /m2/year for detached houses
– 11 kg CO2(eq) /m2/year for attached houses
– 14 kg CO2(eq) /m2/year for low rise apartment blocks (four storeys
and below).
– (A 70% reduction would have equated to 6-8kg/m2/yr)

32. ZCH recommendations cont’d…
• Allowable solutions (relate to off setting / mitigating emissions
off site between Carbon Compliance on site level and 100%)
• ZCH refer to a financial contribution of £75/tonne over
30 years (could typically be in range of £2,000-2,500 per home)
• Compliance on site with Code 5 = no allowable
solutions payments
• Income could potentially be allocated
to energy infrastructure locally or
retrofitting existing homes

33. Interesting ZCH implications
• Averaging to achieve compliance across the development
recommended by ZCH (not all homes would need to meet CC)
• Weather assumptions for different UK locations may be
considered
• As built in-situ checks for compliance (could be as much as 90%
sample, post construction checking at forefront of ZCH report)
• Carbon intensity of the grid in coming years
• Opportunity exists to exceed compliance

34. ZCH and Localism agenda
• ZCH advocate one standard throughout UK
• However, move away from national regulation standards
towards local standards
• LA’s could potentially set higher standards / introduce
standards sooner
– ministers may want rigorous technical analysis on alternative
standards to maintain flexibility for house builders.
– Local plans can potentially be used to set
higher standards but independently
verified as sound proposals.

36. Future role of the CodefSH
• Future perhaps uncertain
• DCLG are owner of the Code (licensed to BRE) and
Code will continue to operate this year
• Likely to be revised to suit ZCH & changes to B Regs
• As a holistic EAM operation expected to continue
(sets wider and more stretching targets over min
standards)
• Regulators / public funders requirements not clear
e.g. HCA
Code 6 homes

38. Issues: the town today
• Economic decline
• Poor town centre
• Disconnected town
• Poor public transport links
• Poor range of house types & tenure
• Lack of employment and business opportunities
• Need to protect habitats and species
• Population
