 ## Unreleased
 
+## [1.2.0] - 2026-08-13
+
+### Added
+
+- 計算完了後に、暖房・冷房別の一次エネルギー消費量、未処理負荷、エアコン消費電力量、
+  ファン消費電力量を年間値と単位付きのカードで表示するようにした。
+
+### Changed
+
+- 入力画面を開いた直後は、①・②を含むすべての入力セクションを閉じた状態にした。
+- 計算ログを、計算条件、実行処理、年間結果、出力ファイル、計算エンジン詳細ログの
+  5区分に整理した。再計算開始時には前回の年間結果を消去し、完了後に新しい結果へ
+  更新するようにした。
+
 ## [1.1.2] - 2026-08-12
