電気容量が高いのに、消費電力が少ない？
この研究では、最新の調理システムの高い電気容量がしばし誤解されているように、エネルギー消費量の増加、ひいては電気料金の上昇につながるわけではないことも証明されています。そうではなく、従来の調理機器と比較してピーク電力が低減しています。これには以下のような理由があります。
- 短い昇温時間
- 高い効率
- 正確で柔軟な熱制御
* 改装前の厨房（左）と改装後の厨房（右）での15分間のピーク電力
- 調査期間：2022～2025年、プロジェクト計画から評価の期間を含む
- 調査協力：ヴァイエンシュテファン＝トリースドルフ応用科学大学
- 改装前：2004年築後、さまざまな厨房装備を追加
- 改装期間：2024年4月～9月
- 改装後の厨房の操業開始：2024年9月
- 2つの同等の測定期間（それぞれ17週間：2023/10/10 - 2024/01/31、2024/11/04 - 2025/02/28）
- エネルギーと水の消費量、スタッフの作業負荷（人間工学）に関する情報、プロセスの変更とそこから生じる調理の柔軟性、食品品質の変化の記録
- 93台の電力メーターと28台の水量計
- 各測定段階で52,000食以上の主菜、合計355,000回以上のレジ通過を評価
- 使用された消費量評価ソフトウェア：Grafana

AXA Konzern AG, Cologne site
With a premium income of €12 billion in 2023 and around 8,000 employees, AXA Konzern AG is one of Germany's largest primary insurers. AXA Konzern AG (AXA Germany) is part of the AXA Group, which is one of the world's leading insurance companies and asset managers. The group operates in Europe, North America, and the Asia-Pacific region. Approximately 3,500 employees at the Cologne site are able to use the company's catering service. On average, around 1,600 of these employees are on site each day. The catering service offers a breakfast and lunch service as well as a wide variety of snacks for in between meals. The lunch service, which is the focus of the study, is served in two restaurants.
Eurest Germany GmbH
Eurest has been contracted to provide catering services for employees of the AXA Konzern AG at its Cologne site. Around 25 Eurest employees are responsible for production at the site. While the menu and food procurement are based on Eurest's central structures, they are carried out in close consultation with colleagues from the AXA Workplace and Infrastructure Management Catering Division.
RATIONAL AG
RATIONAL AG, the market leader in thermal food preparation, commissioned the comprehensive study and provided operational consulting and training services to support the kitchen renovation. For RATIONAL, the study provides scientific confirmation of what has already been demonstrated in countless laboratory tests over many years: that RATIONAL technology can deliver impressive results in everyday kitchen operations.
Weihenstephan-Triesdorf University of Applied Sciences
Weihenstephan-Triesdorf University of Applied Sciences is one of the leading national and international universities of applied sciences and green engineering. Excellent teaching, a strong practical focus and applied research form the core of the university's identity. No other German university offers such a wide range of subjects geared towards green engineering. Across its seven faculties and two campuses, the university offers 19 bachelor's and 13 master's programmes covering ecological, technical, and economic topics.
