> Dear All,
>  
> This morning DECC has published the 2015 edition of the National Energy Efficiency Data-framework (NEED) headline report, presenting analysis of domestic consumption for 2013 and estimates of the consumption savings households experienced following the installation of energy efficiency measures in 2012.  The publication can be accessed here:

>   In summary, the key findings show that:
>  
> The typical saving experienced by properties installing cavity wall insulation in 2012 was 8.4 per cent.  The equivalent figure for properties insulating their loft in 2012 was 2.6 per cent, in line with previously published findings (9.2 per cent and 2.8 per cent respectively for measures installed in 2011).
> The impact of installing a new condensing boiler has been shown for the first time; properties experienced a saving of 9.2 per cent.
> The greatest saving made during 2012 was 21.3 per cent (3,200 kWh), which occurred when a property combined solid wall insulation with a new condensing boiler.
> Properties which had an energy efficiency measure installed in 2005 continued to see savings through the period considered (up to 2012).  For example, cavity wall insulation installed in 2005 still provided a 7.3 per cent annual saving seven years after installation.
> New analysis of the impact of installing solar PV panels in 2012 shows that households’ annual use of mains electricity fell by 16 per cent (600 kWh), compared to a fall of 5 per cent in similar properties that didn’t have solar panels.
>  
>  
> We have also published a number of annexes alongside the main report, including:
> Annex B: Electricity use in households with solar PV panels
> Annex C: Change of occupancy analysis
> Annex D: Scotland
