4PLANET IMPACT / ISSUE
Inefficient buildings
Poor building performance can drive avoidable energy demand for heating, cooling, lighting and equipment.
Why it matters
Reducing operational energy demand can lower system pressure, but performance depends on climate, building fabric, use and energy supply.
What the sources establish
UNEP's global buildings assessment identifies energy efficiency and renovation as important components of reducing the sector's climate impact.
