  • Retrofitting existing houses
  • Retrofitting existing commercial and industrial premises
  • Making new buildings net-zero
  • Minimising energy use by amenity lighting

9.1  Introduction

Buildings and lighting outdoor spaces produced 38% of Devon’s greenhouse gas (GHG) emissions in 2019, shared equally between residential and commercial/industrial buildings. Burning fossil fuels for heating and manufacturing processes are responsible for 19% and 6% respectively. The remaining 13% is from the consumption of grid-supplied electricity.1

This section focusses on how we can achieve net-zero buildings based on the Climate Change Committee’s (CCC) Further Ambition Scenario.2 It then introduces goals for overcoming issues identified during the Thematic Hearings and the public Call for Evidence as barriers to achieving net-zero in Devon. Actions are then proposed to achieve the goals.

The Energy Supply section of the Plan explores decarbonising the electricity supply, including support for building-scale renewable electricity and energy storage. The Economy and Resources section of the Plan discusses how we can ensure we have the necessary skills in Devon to achieve net-zero, including the skills needed to upgrade buildings.
