Zero energy (ZE) and zero carbon (ZC) buildings are becoming the new standard for achieving significant energy savings and greenhouse gas emissions in the built environment.
-
A zero energy building is an ultra-efficient buildings that produces as much renewable energy as it consumes over the course of a year.
-
A zero carbon building is defined as one that is highly energy-efficient and produces onsite, or procures, carbon-free renewable energy in an amount sufficient to offset the annual carbon emissions associated with operations.
