Summery 1. Long life, comfort, save energy, energy self independent house is the standard “Smart House”. Energy management 長寿命で、「快適」「省エネ」「エネルギー自立可能」な住宅が 『スマートハウス』の基本 エネルギー マネージメント Store energy 2. To circulate the “Smart House” It is necessary to increase cost performance for the customer. スマートハウスの普及のためには、住まい手の コストパフォーマンスをいかに高めるかがポイント 蓄エネルギー Create energy 創エネルギー Save energy 省エネルギー型住宅 3. Appealing the whole house which packaged by a best combinations of elemental technology is important. 要素技術を最適パッケージ化した住宅(全体)の訴求が重要 4. Energy balance would be more intensify. The point is how to correspond to these problems. エネルギーの需給バランスの変化は激しくなる その変動にいかに対応するかが今後のスマートハウス普及の鍵になる Page 21 SEKISUI CHEMICAL CO., LTD.
