CHP electricity not used by the building

I'm modeling a building where hot water is provided by a district heating system. The district heating system is a cogeneration system (CHP). The produced electric energy is sold to the national network directly. Therefore the building uses the hot water that is produced by CHP, but it doesn't use the electricity that is produced by CHP. During summer the hot water is used for the production of chilled water through an absorption chiller. I'm considering Appendix G of “Treatment of District or Campus Thermal Energy in LEED”. It states that the electricity shall be allocated to the considered building through an equation. Since in our case the building doesn't use the electricity that is produced by CHP, I'm wondering whether that approach makes sense. If it doesn't make sense, I would like to consider an “allocation factor” and multiply the fuel input by that allocation factor, as it is defined by equation 2 of “Treatment of Scandinavian District Energy Systems in LEED v1 2012”: http://www.usgbc.org/resources/treatment-scandinavian-district-energy-systems-leed-v1-2012-0 Would it be possible? Consider that the building is located in Italy and the Italian technical standards provide values relative to the “alternative production efficiency for heat production” and the “alternative production efficiency for electricity production”. Shall I apply all the Scandinivian document (calculation of PEF and CO2e, of the performance factor...)? Do you see better alternatives? Regards
