What does net Zero Carbon ‘in use’ actually mean?

Zero Carbon (in use) refers to operational carbon; this is the carbon emissions generated during the building’s lifetime relating to its use and principally arising from the building’s energy demand. To achieve zero net emissions, we therefore need to be able to offset our actual energy use with energy derived from renewable energy sources.

The homes will become so well performing that the energy required to heat, and maintain the heat, is expected to considerably reduce.  On similar projects annual heating bills have reduced to roughly £40 per annum.
