Smart　building　is　the　result　of　the　penetration　of　information　technology　and　control　technology　into　traditional　buildings,　and　is　the　future　development　direction　of　buildings.　User-centric　building　smart　design　can　achieve　a　sustainable　life,　and　smart　technology　integration　based　on　smart　design　can　support　sustainable　development　and　improve　user　satisfaction,　happiness,　and　overall　quality　of　life.　In　intelligent　design,　researchers　focus　on　the　＂people-oriented＂　approach,　designed　to　bring　users　the　ultimate　interactive　experience.　Based　on　the　interactive　experience　principle　of　smart　design　in　the　smart　building　system,　this　article　classifies　and　summarizes　intelligent　design　from　the　＂five　senses＂　interaction,　including　visual　interaction,　voice　interaction,　tactile　interaction,　cognitive　interaction,　and　emotional　interaction.　We　analyze　the　application　of　smart　design　in　architecture　and　discuss　how　to　embody　the　principles　of　user-centered　interactive　experience　design　in　the　process　of　smart　design.　This　article　provides　a　comprehensive　and　systematic　literature　review,　clarifies　the　importance　of　the　＂people-oriented＂　approach　in　the　smart　design　of　buildings,　and　summarizes　how　to　improve　the　sustainability　of　intelligent　buildings　from　the　perspective　of　a　＂people-oriented＂　approach.　This　paper　proposes　future　research　suggestions　and　directions　and　promotes　the　sustainable　development　of　the　smart　building.　©　2020　by　the　authors.
