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
Investing in Opportunities
http://GreenBuildingEncyclopaedia.uk
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
Investing in Opportunities
http://GreenBuildingEncyclopaedia.uk
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?
