The UK Doctoral Training Centre in Energy Demand Reduction and the Built Environment impact? 1. Increased seasonal water shortages 2. Increased risk of flooding + localized flash floods 3. Decreased winter fuel-poverty 4. Increased summer cooling-poverty and health related issues (particularly the elderly at risk)

The UK Doctoral Training Centre in Energy Demand Reduction and the Built Environment avoidable?

The UK Doctoral Training Centre in Energy Demand Reduction and the Built Environment avoidable? Yes!

The UK Doctoral Training Centre in Energy Demand Reduction and the Built Environment avoidable? But we have to future-proof today.

The UK Doctoral Training Centre in Energy Demand Reduction and the Built Environment Sounds simple?

The UK Doctoral Training Centre in Energy Demand Reduction and the Built Environment It is!

The UK Doctoral Training Centre in Energy Demand Reduction and the Built Environment because 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 Environment How? By choosing housing interventions which both mitigate and adapt to climate change

The UK Doctoral Training Centre in Energy Demand Reduction and the Built Environment How? 5 key interventions

The UK Doctoral Training Centre in Energy Demand Reduction and the Built Environment 1. insulate Going to zero carbon

The UK Doctoral Training Centre in Energy Demand Reduction and the Built Environment 1. insulate Going to zero carbonInsulation & increased airtightness reduce winter heat loss but also summer heat gains.

The UK Doctoral Training Centre in Energy Demand Reduction and the Built Environment 1. insulate Going to zero carbon Insulate existing housing stock to high standards
