Understanding　of　sealing　performance　of　rural　housing　is　very　important　in　reducing　energy　consumption　for　heating　demand.　This　paper　illustrates　the　identification　of　infiltration　rates　through　windows　and　doors　in　rural　housing　through　temperature　measurements.　Room　air　temperatures　were　measured　hourly　from　2009-02-08　to　2009-02-17　in　one　rural　housing　in　Beijing.　During　the　measuring　period,　there　is　no　one　living　in　this　house　and　all　the　windows　and　doors　have　been　closed.　The　room　air　temperatures　were　simulated　using　DeST-h.　The　infiltration　rate　at　each　hour　was　identified　by　minimizing　the　gap　between　the　measured　temperature　and　the　simulated　temperature.
