In partnership with Glasgow University and NHS Ayrshire
& Arran, Energy Agency conducted research into the impacts of home energy
efficiency measures on resident’s wellbeing and hospital admissions in South
West Scotland. The two part study took place over ten years monitoring the
health of occupant’s pre energy efficiency works and post installation of
External Wall Insulation (EWI). This work, on behalf of South and East Ayrshire
Councils, is managed by the Energy Agency.

After a lengthy peer review process, the results have now
been published in Public Health in Practice https://doi.org/10.1016/j.puhip.2023.100396

The findings
suggest ‘a small but significant improvement in the health of residents’ and
provides
evidence that home insulation improvements not only lead to
reduced emissions, lower energy bills and a lower carbon footprint, but also a
corresponding reduction in hospital admissions for respiratory and cardiovascular
conditions.

This work also
supports the All Party Parliamentary Group for Healthy Homes and Buildings’
call for better measurement of the economic and social impacts of healthier
homes. It is one of the few UK Studies to provide evidence that shows the multiple
benefits from energy efficiency works; reducing energy demand (and thus
household bills), contributing to net zero goals, and alleviating pressures on
health service bed-spaces.  This is an
exemplar of joined-up policy with political and practical benefits.

Statement by Liz Marquis, Director
Energy Agency:

We are delighted
that close working with partners allows government funding to be used as
effectively as possible to consider all aspects of housing, health and energy
to benefit everyone. This practical work also provides real data analysed by
academics and the health sector showing the many benefits.

Statement by Elaine Caldow, Public Health Programme Lead:

We know that in order to improve health and wellbeing and tackle health inequalities, we need to ensure everyone has access to a warm, dry, safe, affordable home which meets their needs. The pathway between housing and health is complex, however, home improvements which increase warmth and energy efficiency have the potential to improve health and wellbeing.

The Public Health Team in NHS Ayrshire
& Arran has been working with the Energy Agency, in partnership with South
and East Ayrshire Councils, to observe the impacts of the 
Energy Efficient Scotland: Area
Based Scheme 
on health and wellbeing. This scheme aims to improve the energy efficiency of homes and
reduce fuel poverty in the most deprived communities.

Within NHS Ayrshire & Arran, we
looked at secondary data
over a period of time for hospital admissions for
conditions known to be affected by cold or damp homes 
and observ
ed relatively lower hospital admissions for both respiratory and cardiovascular and circulatory conditions in the areas which received the home improvements, compared to the rest of the health board area. The study also found
improvements in thermal comfort following external wall insulation, which
 was associated with self-reported
improvements
 in physical health. The study is a further step in our
understanding of how improving the warmth and the physical environment of our
homes can contribute to health outcomes.
