And there is in all these things a risk of double-counting.  \r\n\r\nHowever, the best and easiest way to avoid this is to simply do what SAP does and count it all against the house where it is generated. See page 35 of the SAP document: \"CO2 emissions attributable to a dwelling are those for space and water heating, ventilation and lighting, less\r\nthe emissions saved by energy generation technologies.\" Also page 86 for a bit more detail. \r\n\r\nWe shouldn't allow other houses to claim it for using a 'green' electricity tariff (which is a highly debatable notion, and is likely 'double counting' on its own, as the grid carbon intensity number already includes the contribution of all renewables in the country - and the next person to come along can easily change this, it's not 'fixed' infrastructure). In any case, it is the PVs on the house being considered that have allowed this energy to be saved. \r\n\r\nThat way, there's still a strong incentive for renewable energy, whilst still acknowledging the contribution to the grid. \r\n\r\nHope that's clear. \r\n\r\nMarianne "}}
