Based on the data on the inlet side energy flow rate of the utility equipment having the staying part, the carbon dioxide emission basic unit of the inlet side energy, the outlet side energy flow rate, and the staying part staying amount data, The carbon dioxide emission basic unit at each time is calculated by calculating the mass balance of carbon dioxide between time t and time t + Δt (time increment) for the carbon emission basic unit. 6. The carbon dioxide emission calculation method according to 6. The utility equipment managed by the utility management means includes utility equipment that generates heat, having a heat exchanger that transfers energy from a primary heat source to a secondary heat source,
The emission unit calculation means further includes:
The flow rate and temperature data of the primary utility that flows into the utility equipment that generates the exhaust heat and the flow rate and temperature data when the inflow utility flows out as exhaust heat are acquired from the utility management means. The carbon dioxide emission basic unit in consideration of the temperature information of utility is calculated. The carbon dioxide emission calculation method according to claim 6, wherein: The emission unit calculation means is:
The carbon dioxide emission calculation method according to claim 8, wherein the temperature information of the utility is enthalpy of utility. The emission unit calculation means further includes:
The utility management means obtains data on the flow rate of each utility flowing into the merger of the utility from a plurality of utility facilities that produce the same utility, and discharges carbon dioxide in consideration of the flow rate ratio of the utility The carbon dioxide emission calculation method according to claim 6, wherein the basic unit is calculated.
