低温屋根エネルギー計算機

ダウ・クール・ルーフ・エネルギー計算機

現代のビルのエネルギー効率は、CO2 排出量の削減など、サステナビリティ目標の達成と、都市部の人々の生活水準の向上を同時に実現する大きな可能性をもたらします。これに対する最も重要な貢献は、建物の内部温度を制御するために使用されるエネルギーの量を減らすことです。これは、より涼しい気候での断熱によって達成できますが、より暖かい地域では、Cool Reflective Roof Coatings (CRRC) などの日射の影響を軽減する対策が非常に効果的です。

冷却反射ルーフコーティング

涼しい反射屋根コーティングは、内部温度を下げるだけでなく、冷却のためのエネルギーコストを下げるだけでなく、気候要素に対する保護を提供することで屋根の寿命を延ばすのに役立ちます。

ダウのクールルーフエネルギー計算機

ダウのクールルーフエネルギー計算機は、屋根にCRRC技術を使用することで、エネルギー節約の可能性を見積もることができるように設計されています。ヨーロッパ、中東、アフリカ、インドの15の都市で、異なる屋根&壁のビルドアップとサイズで、3種類の建物(住宅、商業、倉庫)の建物エネルギーシミュレーションを実施することで、全体的なエネルギー消費量と部屋および屋根の温度を計算します。
