<p>The Strategy for Defence Infrastructure, published in Jan 2022, sets the ambition
for a Net Zero built estate with a focus on reducing emissions through reducing demand,
increasing efficiency, and moving away from fossil fuels. Initiatives to improve insulation
are key to increasing the efficiency of the built estate, reducing running coasts,
improving the thermal comfort of Defence people, helping to reduce energy bills for
Service Families, and improving resilience against the impacts of Climate Change.</p><p>
</p><p>Defence has invested over £500 million in Service Family Accommodation (SFA)
over the past three financial years which includes a drive to improve the thermal
efficiency of homes and to meet EPC C ratings by 2035 . This includes: over 1,000
homes with external wall insulation; 600 new boilers; 4,000 new roofs; and 2,600 homes
with new doors and windows. Defence is also progressively increasing loft insulation
across the Estate to a depth of 300mm versus the industry standard of 270mm.</p><p>
</p><p>Additionally, Defence is delivering a £2 billion investment programme to improve
Single Living Accommodation (SLA) over the next 10 years to ensure the Defence Minimum
Standard is met, including for thermal comfort, and providing c40,000 new bedspaces
that meet Net Zero building standards.</p><p> </p><p>Although there are currently
no specific targets in place for insulation, it is recognised that good levels of
insulation will be required across the whole of the built estate to meet our Net Zero
ambition. A supporting Estate Sustainability Sub-Strategy is under development to
plot the route to Net Zero (roadmap) which will include energy efficiency interventions.
The roadmap will be informed by a decision support tool that will identify optimal
interventions in terms of value for money and emission reduction e.g. insulation or
LED lighting programmes.</p>
