To　reduce　heating　load　of　bedroom　while　ensure　sleep　thermal　comfort,　this　study　examined　two　temperature　control　modes　of　bedroom　heating,　including　a　stable　temperature　control　throughout　the　night　and　a　downward　change　during　sleep.　The　former　mode　adopted　two　steady　indoor　temperature　of　14　and　18℃　respectively,　and　the　latter　conducted　a　control　pattern　of　18-14-18℃.　In　each　condition,　before　falling　asleep　and　after　waking　up,　the　thermal　sensation　votes　and　thermal　acceptability　were　collected　from　twelve　lying　subjects　on　whole　body　as　well　as　on　seven　major　body　segments.　The　preliminary　results　indicated　that　subjects　felt　both　conditions　of　18℃　and　18-14-18℃　were　thermally　acceptable　and　the　overall　and　local　thermal　sensation　were　nearly　neutral.　In　the　stable　condition　of　14℃,　the　subjects　reported　significantly　cooler　thermal　sensation　and　thermal　unacceptance,　especially　in　the　head　and　foot.　©　2024　18th　Conference　of　the　International　Society　of　Indoor　Air　Quality　and　Climate,　INDOOR　AIR　2024　-　Conference　Program　and　Proceedings.　All　rights　reserved.
