UK Housing Stock Stats

•  The UK has the oldest housing stock in the developed world

•  One in five UK homes were built before 1918 –  50% of homes are over 50 years old –  20% are over 100 years old and have solid walls

•  6 million homes were classified as ‘non decent’ •  More than 800,000 were vacant

–  could be refurbished properly and unhindered –  making way for a further 800,000

•  Buy-to-leave-empty was on the increase •  Brexit may put an end to that?

27/09/17

EPC Energy Performance Certificate's

•  Current energy efficiency rating bands •  all homes:

–  41% rated band E •  Houses

–  10% of band A or B in 2006. •  Flats:

–  39% band D –  25% bands A-C

•  But what matters to people? •  Location, Location, Location:

–  Schools catchment areas –  Good areas v bad –  Trains v good roads, 43

SAP Standard Assessment Procedure

energy efficiency rating •  Scale: worst 0-100 best •  Housing stock average SAP rating:

– 1996: SAP = 42 – 2006: SAP = 49 – 2010: SAP = 52

•  Many not energy efficient – Mean rating SAP = 52 – Target rating SAP = 80




Built Environment Retrofit Stats &

Objectives





UK objectives

•  Existing housing stock: release150 m tonnes CO2/annum

•  older buildings contributing disproportionately.

•  November 2008 Climate Change Bill –  Revised target: –  80% reduction in carbon emissions by 2050 –  100% is impossible looking at buildings alone

•  sustainable refurbishment best practice will contribute significantly

•  central & key part of market transformation of the construction sector.

27/09/17 46

Scale of Mass Retrofitting

•  27 m homes •  By 2030 all buildings: Low Energy

•  Need to retrofit: –  500,000 properties/annum before 2020 –  240,000/annum 2020 onwards

•  The longer the recession lasts and the longer we take to start

•  the faster we will need to go when we do start –  700,000/annum was 2010 requirement 27/09/17 48



Economic opportunity

•  £135 bn/annum industry needed •  £28 bn over 8 years (domestic) •  £3.5 bn/annum •  3500 homes/day

–  (but not in a day that would be madness, –  or Television entertainment –  And bad construction methods to boot)

•  40,000 – 150,000 jobs created •  But the economy was flat

–  everybody was cutting back making the challenge even greater later

•  GreenDeal never got going –  2nd attempt starting

•  ECO did a lot of work some very badly 27/09/17 50



Are we fit for purpose?

•  Are we up to the job

•  Do we know what the job is?

•  Can we convert from New build Constructors to Refurbishers?

•  The government did not think so

•  So it acted finally, too much, too soon, to kill off its own scheme, or did it?
