Thermal performance of buildings and building components - Physical quantities and definitions (ISO 7345:2018)

ISO 7345:2018 defines physical quantities used in the thermal performance of buildings and building elements, and gives the corresponding symbols and units.
NOTE       Because the scope of this document is restricted to thermal performance and energy use in the built environment, some of the definitions it contains differ from those given ISO 80000-5.

Wärmeverhalten von Gebäuden und Baustoffen - Physikalische Größen und Definitionen (ISO 7345:2018)

Diese Internationale Norm definiert physikalische Größen aus dem Bereich des Wärmeverhaltens von Gebäuden und Baustoffen und enthält die entsprechenden Symbole und Einheiten.
ANMERKUNG   Da der Anwendungsbereich dieser Internationalen Norm auf den Bereich des Wärmeverhaltens und der Energienutzung in baulichen Anlagen beschränkt ist, unterscheiden sich einige der in Abschnitt 2 angegebenen Definitionen von den Definitionen in ISO 80000 5 Größen und Einheiten — Teil 5: Thermodynamik (ISO 80000 5:2007).

Performance thermique des bâtiments et des matériaux pour le bâtiment - Grandeurs physiques et définitions (ISO 7345:2018)

Le présent document définit les grandeurs physiques utilisées dans le domaine de la performance thermique des bâtiments et des matériaux pour le bâtiment, et fournit les symboles et unités correspondants.
NOTE       Le domaine d'application du présent document étant limité à la performance thermique et à l'utilisation de l'énergie dans l'environnement bâti, certaines des définitions qu'il contient diffèrent de celles citées dans l'ISO 80000‑5.

Toplotne značilnosti stavb in delov stavb - Fizikalne količine in definicije (ISO 7345:2018)

Ta mednarodni standard določa fizikalne količine, uporabljene pri toplotnih značilnostih stavb in elementov stavb, ter podaja ustrezne simbole in enote.
OPOMBA: Ker je področje uporabe tega mednarodnega standarda omejeno na toplotne značilnosti in uporabo energije v stavbenem okolju, se nekatere definicije iz točke 2 razlikujejo od definicij, podanih v standardu ISO 80000-5 Veličine in enote – 5. del: Termodinamika (ISO 80000-5:2007).
