from now,…
The UK Doctoral Training Centre in Energy Demand Reduction and the Built EnvironmentI should be
The UK Doctoral Training Centre in Energy Demand Reduction and the Built EnvironmentI should be
87 years old

The UK Doctoral Training Centre in Energy Demand Reduction and the Built EnvironmentBut will I?
Probably not,…

by 2050
The UK Doctoral Training Centre in Energy Demand Reduction and the Built EnvironmentBecause
by 2050London will

The UK Doctoral Training Centre in Energy Demand Reduction and the Built Environmentthis is fatal
to many elderly
The UK Doctoral Training Centre in Energy Demand Reduction and the Built EnvironmentWhy?
The UK Doctoral Training Centre in Energy Demand Reduction and the Built EnvironmentWhy?
1. NO global effort to reduce carbon emissions so unabated climate change:2-6ºC temperature rise
The UK Doctoral Training Centre in Energy Demand Reduction and the Built EnvironmentWhy?
1. NO global effort to reduce carbon emissions so unabated climate change:2-6ºC temperature rise
2. UK failed to meet its 80% CO2 reduction by 2050

1. NO global effort to reduce carbon emissions so unabated climate change:2-6ºC temperature rise
2. UK failed to meet its 80% CO2 reduction by 2050
3. ≈75% of buildings which exist today will still exist in
2050; of which 26 million dwellings

emissions and are ill-adapted to London’s changing climate

The UK Doctoral Training Centre in Energy Demand Reduction and the Built Environmentavoidable?
The UK Doctoral Training Centre in Energy Demand Reduction and the Built Environmentavoidable?
Yes!
The UK Doctoral Training Centre in Energy Demand Reduction and the Built Environmentavoidable?
But we have to future-proof
today.
The UK Doctoral Training Centre in Energy Demand Reduction and the Built EnvironmentSounds
simple?
The UK Doctoral Training Centre in Energy Demand Reduction and the Built EnvironmentIt is!
The UK Doctoral Training Centre in Energy Demand Reduction and the Built Environmentbecause
Although these conditions are new to London, we can borrow from
other climates in the world (Mediterranean, Netherlands)
The UK Doctoral Training Centre in Energy Demand Reduction and the Built EnvironmentHow?
By choosing housing interventions which both
mitigate and adapt to climate change
The UK Doctoral Training Centre in Energy Demand Reduction and the Built EnvironmentHow?
5 key interventions
The UK Doctoral Training Centre in Energy Demand Reduction and the Built Environment1. insulate
Going to zero carbon
The UK Doctoral Training Centre in Energy Demand Reduction and the Built Environment1. insulate
Going to zero carbonInsulation & increased airtightness reduce winter heat loss but also
summer heat gains.

Going to zero carbonWe need to think about external insulation (retains thermal mass,
reduces thermal bridging & other risks)

Going to zero carbonwhile increasing airtightness we need to allow for biodiversity habitats!

biodiversity…because striving for increased
airtightness reduces opportunities for birds to nest & bats to roost in gaps &
cracks of old buildings.

The UK Doctoral Training Centre in Energy Demand Reduction and the Built Environment2.greenery
Increase greenery, permeable surfaces & water storage – at micro
and macro scale
The UK Doctoral Training Centre in Energy Demand Reduction and the Built Environment2.greenery
This will: •increase biodiversity
