Household　heat　metering　has　become　an　inevitable　trend　in　the　reform　of　heating　in　northern　China,　and　it　aims　to　realize　energy　saving　from　users’　behavior　while　ensuring　the　indoor　thermal　comfort.　Due　to　the　different　building　envelopes,　occupants’　preference　and　occupancy　rate　of　each　house,　the　heat　transfer　from　adjacent　room　will　greatly　affect　the　fair　share　of　the　household’s　heating　fee.　This　study　adopts　EnergyPlus　for　building　modeling　and　heating　load　calculation.　A　total　of　17　rooms　in　one　building　are　measured　with　temperature　in　both　indoor　and　outdoor　from　Jan　22　to　Feb　5,　2018.　Building　model　is　established　according　to　the　real　building　plan　and　envelope　materials,　and　the　time-dependent　temperature　of　the　simulated　room　is　compared　with　the　minutely　measured　temperature　to　validate　the　model　accuracy.　With　the　valid　model,　the　actual　ratios　of　heat　transfer　go　to/from　adjacent　room　to　the　heating　load　are　calculated.　The　results　indicate　that　the　heat　transfer　to　adjacent　rooms　in　one　day　accounts　for　near　70%　of　the　total　heating　load,　which　will　provide　basic　data　for　fair　heating　charging　and　be　conducive　to　the　implementation　of　household　heat　metering　in　China.　©　2020,　Springer　Nature　Singapore　Pte　Ltd.
