This European Standard covers the energy performance calculation of mechanical ventilation and air conditioning systems, including humidification and dehumidification. It takes into account the generation (air handling unit) and distribution (duct system) parts. It includes a simplified calculation of adiabatic cooling systems. It does not cover the emission part (calculation of the required volume flow rates and/or supply air conditions), which is covered in EN 16798-7. It does not include the calculation of heating/cooling generation. This method is focussed on large customized ventilation and air conditioning systems, typically used in commercial buildings, although the application is not restricted on the basis of building or space use type.
A calculation method for ventilation systems with integrated heating/cooling generation, including domestic hot water generation, using a monthly or seasonal calculation interval or a bin method, is provided in a separate standard, EN 16798-5-2. This method does not include humidification and dehumidification or adiabatic cooling.

Diese Europäische Norm gilt für die Berechnung der Energieeffizienz von mechanischen Lüftungs- und Klima¬anlagen, einschließlich Be- und Entfeuchtung. Sie berücksichtigt die Teile zur Erzeugung (zentrales raum¬lufttechnisches Gerät) und zur Verteilung (Luftleitungssystem). Sie enthält eine vereinfachte Berech-nung der adiabatischen Kühlungssysteme. Sie behandelt nicht den Teil zur Übergabe (Berechnung der erforderlichen Luftvolumenströme und/oder Zuluftbedingungen), der durch EN 16798 7 abgedeckt ist. Sie umfasst nicht die Berechnung der Wärme-/Kälteerzeugung. Dieses Verfahren konzentriert sich auf große, individuelle geplante Lüftungs- und Klimaanlagen, wie sie gewöhnlich in Nichtwohngebäuden verwendet werden, auch wenn die Anwendung nicht in Hinsicht auf die Art des Gebäudes oder der Raumnutzung eingeschränkt ist.
Ein Berechnungsverfahren für Lüftungsanlagen mit integrierter Wärme-/Kälteerzeugung, einschließlich der Brauchwarmwasserbereitung, unter Anwendung eines monatlichen oder saisonalen Berechnungsintervalls oder eines Bin Verfahrens ist in einer separaten Norm, EN 16798 5 2, enthalten. Dieses Verfahren umfasst weder die Be- noch die Entfeuchtung oder die adiabatische Kühlung.

The EN 16798-5-1:2017 standard is a comprehensive framework designed for assessing the energy performance of mechanical ventilation and air conditioning systems within buildings. Its primary focus lies in providing calculation methods for the energy requirements associated with such systems, encompassing both generation through air handling units and distribution via duct systems. Notably, this standard integrates aspects of humidification and dehumidification, emphasizing its relevance in modern building environments that prioritize indoor air quality alongside energy efficiency. One of the standout strengths of the EN 16798-5-1 is its modular approach, as referenced in the comprehensive table that illustrates its relationship with other EPB standards outlined in EN ISO 52000 1. This modularity not only clarifies the standard’s application but also provides a clear connection between various calculation methods, facilitating a more user-friendly experience for professionals in the field. Furthermore, while the standard primarily caters to large, customized ventilation and air conditioning systems typical in commercial contexts, it remains adaptable to a variety of building types, enhancing its applicability across different sectors. The inclusion of a simplified calculation for adiabatic cooling systems serves as a significant advantage in terms of usability, promoting ease of application without compromising accuracy. Additionally, the standard effectively delineates its scope by excluding certain elements, such as emission calculations and heating/cooling generation, which are addressed in other standards like EN 16798-7 and EN 16798-5-2. This delineation aids users in selecting the appropriate standards for their specific project needs, thereby streamlining the entire process of energy performance assessment. Overall, EN 16798-5-1:2017 is a vital resource for architects, engineers, and facility managers seeking to optimize energy performance in ventilation and air conditioning systems. Its structured methodology not only supports compliance with existing regulations but also aligns with broader sustainability goals in the building sector. The focus on energy efficiency through well-defined calculation methods makes this standard particularly relevant as the industry increasingly shifts towards greener practices.
SIST EN 16798-5-1:2018 표준은 건물의 에너지 성능 및 기계 환기와 공기 조화 시스템의 에너지 요구량 계산에 대한 중요한 지침을 제공합니다. 이 표준은 주로 상업용 건물에 사용되는 대규모 맞춤형 공조 시스템에 대한 계산 방법을 다루고 있으며, 따라서 공조 시스템 설계 및 성능 평가에 필수적인 요소로 자리잡고 있습니다. 이 표준의 강점은 기계적 환기 및 공조 시스템의 생성과 분배를 모두 포함하여, 유량 및 공기 조건을 평가하는 데 필요한 다각적인 접근 방식을 제공한다는 점입니다. 특히, 간소화된 냉각 시스템 계산을 통해 실용적인 측면에서의 적용성을 높이고 있습니다. 그러나, 난방 및 냉방 생성의 계산은 포함되지 않으며, 이는 EN 16798-5-2에서 별도로 다루어지고 있다는 점이 주목할 만합니다. SIST EN 16798-5-1:2018 표준은 EN 16798-7에서 다루어지는 배출 부분의 계산을 포함하지 않기 때문에, 이 점을 유의해야 합니다. 이는 각기 다른 표준의 모듈 구조에 따라 설정된 EPB 표준의 계층적 접근 방식을 통해 효과적으로 관리됩니다. 각 모듈은 독립적으로 기능할 수 있으며, 필요에 따라 서로 연계될 수 있습니다. 결론적으로, SIST EN 16798-5-1:2018 표준은 건물의 에너지 성능을 평가하는데 필수적인 도구로서, 효율적인 환기 및 공조 시스템 설계의 기반을 제공합니다. 이는 건물 에너지 성능 기준(EPB)과 긴밀하게 연계되어 있어, 지속 가능한 건축 솔루션을 위한 중요한 기준이 되고 있습니다.
EN 16798-5-1:2017は、建物のエネルギー性能に関する重要な標準であり、機械換気および空調システムのエネルギー要件を計算するための方法を提供します。この標準は、湿度管理やデハミディフィケーションを含む換気および空調システムのエネルギー性能の計算を対象にしており、特に商業ビルにおける大規模なカスタマイズされたシステムに焦点を当てています。 この標準の強みは、機械換気システムと空調システムの発生（空気処理装置）と配布（ダクトシステム）の部分を考慮に入れた詳細な計算方法を提供している点です。また、簡易的なアディアバティック冷却システムの計算も含まれており、ユーザーが多様なシステムを効果的に評価できるようになっています。さらに、この標準はEN 16798-7でカバーされる必要な流量や供給空気条件の計算には関与しておらず、特定の範囲に集中しているため、実務において非常に実用的です。 この標準の関連性は、エネルギー効率を向上させるための国際的な取り組みの一環として顕著です。大規模換気および空調システムを扱うための手法は、今後の建物のエネルギー性能改善において不可欠であり、特に持続可能な建築の目的に適合しています。さらに、この標準は、年月や季節に基づいた計算法も提供する第2部であるEN 16798-5-2と連携しているため、より包括的なアプローチが可能です。 全体として、EN 16798-5-1:2017は、建物のエネルギー性能を評価する上での重要なガイドラインを提供しており、換気および空調システムの計算方法についての権威として、業界内におけるその有用性は高いと評価されます。
