Abstract: A heat sealable resin composition includes an ethylene-vinyl ester copolymer (A), and a tackifier resin (B), a content ratio of a constituent unit derived from a vinyl ester included in the ethylene-vinyl ester copolymer (A) is 8% by mass or more with respect to total copolymer constituent units constituting the ethylene-vinyl ester copolymer (A), and the tackifier resin (B) includes an alicyclic hydrocarbon resin (B1) and an aromatic hydrocarbon resin (B2).

Abstract: Breakdown estimation unit obtains, by first processing portion, component ratio, by application, of energy usage amount in year using model case, and prorates, by second processing portion, record value of energy usage amount in year, by application, with component ratio obtained by first processing portion. Breakdown estimation unit prorates, by month, by third processing portion, energy usage amounts obtained by the second processing portion, excluding energy usage amount of one application, with component ratio, by month, of energy usage amount of the corresponding application in model case. Breakdown estimation unit estimates, by fourth processing portion, for each month, residual amount obtained by subtracting energy usage amounts prorated by third processing portion from record value of energy usage amount as the energy usage amount of the one application in month.
