What is?
Net Zero
It is about balancing your home’s total energy use with renewable production.
Zero Carbon
It is about eliminating your home’s contribution to climate change — including its construction and operation.
Net Zero Energy House
Produces as much energy as it consumes annually. If your house uses 10,000 kWh/year, it must generate 10,000 kWh/year.
Key Points:
-
Prioritizes energy efficiency and on-site renewable energy (usually solar).
-
Energy usage is offset by energy generation.
-
Grid-connected homes may pull electricity at night but feed back during the day.
Zero
Carbon House
Emits no net carbon emissions during both operation and, in some cases, construction.
For example, a house that uses only solar electricity and sustainable materials could be zero carbon, even if it uses more energy than a net zero home.
Key Points:
-
Focuses on eliminating carbon, not just energy use.
-
Must be powered by renewables (on-site or purchased).
-
May include embodied carbon from materials (e.g., concrete, insulation, steel).
-
Sometimes includes offsets if full carbon elimination isn't possible.
