Monitoring indicators
BUILT ENVIRONMENT
This page focuses on tracking Devon’s efforts to create sustainable and resilient buildings and infrastructure. We monitor key indicators such as energy efficiency in buildings, the installation of low carbon heating technologies and the reduction of greenhouse gas emissions from the built environment. Our goal is to retrofit existing houses and commercial and industrial premises, ensure new buildings are net-zero, and minimise energy use.
