ISO 13786:2017

Thermal performance of building components — Dynamic thermal characteristics — Calculation methods

Edition date: 2017-06-21
In Force
Available languages: English, French
Summary:

L'ISO 13786:2017 spécifie les caractéristiques relatives au comportement thermique dynamique d'un composant de bâtiment à l'état fini et fournit des méthodes pour le calcul de ces caractéristiques. Il spécifie également l'information requise sur les matériaux de construction, pour l'utilisation du composant de bâtiment. Les caractéristiques étant dépendantes de la façon dont les matériaux sont combinés pour constituer des composants de bâtiment, l'ISO 13786:2017 ne s'applique pas à des matériaux de bâtiment ou à des composants de bâtiment inachevés.

Les définitions données dans l'ISO 13786:2017 sont applicables à tout composant de bâtiment. Une méthode de calcul simplifiée est donnée pour des composants plans constitués de couches planes homogènes ou quasi homogènes de matériaux de construction.

L'Annexe C spécifie des méthodes simplifiées pour l'estimation de la capacité thermique dans certains cas limités. En particulier, ces méthodes conviennent pour calculer les propriétés thermiques dynamiques nécessaires à l'estimation de la consommation d'énergie. Cependant, ces approximations ne conviennent pas pour caractériser des produits.

NOTE Le Tableau 1 de l'Introduction indique la position relative de l'ISO 13786:2017 dans la série de normes PEB dans le contexte de la structure modulaire définie dans l'ISO 52000‑1.



ISO 13786:2017 specifies the characteristics related to the dynamic thermal behaviour of a complete building component and provides methods for their calculation. It also specifies the information on building materials required for the use of the building component. Since the characteristics depend on the way materials are combined to form building components, ISO 13786:2017 is not applicable to building materials or to unfinished building components.

The definitions given in ISO 13786:2017 are applicable to any building component. A simplified calculation method is provided for plane components consisting of plane layers of substantially homogeneous building materials.

Annex C provides simpler methods for the estimation of the heat capacities in some limited cases. These methods are suitable for the determination of dynamic thermal properties required for the estimation of energy consumption. These approximations are not appropriate, however, for product characterization.

NOTE Table 1 in the Introduction shows the relative position of ISO 13786:2017 within the set of EPB standards in the context of the modular structure as set out in ISO 52000-1.

Frequently Asked Questions Do you have any questions about our products?
  • Standards UNE, EN, ISO, IEC, BSI, DIN, ASTM, AFNOR, IEEE, SAE
  • In addition, you can request the rules of the rest of the organizations through the e-mail normas@aenor.com
  • Technical books on paper and in electronic format (PDF, epub).

The standards can be purchased in PDF, reading or paper. The reading standards are not download files, they can only be viewed in the client area. The standards ordered on paper and some of the books in the catalogue are printed on demand. 

Check deadlines in normas@aenor.com.

The license of use is for one user and one device, if you want to reproduce the content of the standard, you must request a license that will have an additional cost. Send us your inquiry here 

The AENOR standards and books that appear in the online store can only be purchased exclusively through the website. AENOR does not have a physical store.

Purchase procedure: by clicking on "Buy" the desired products will go to the shopping cart. If there are display problems, the recommended browser is Chrome.

To formalize the purchase you must access the customer area. If you are not registered as a customer, you must fill in a form with the data along with a password and username. This will create the account.

Once the "Customer data" form has been completed, "Order in progress" will be displayed with all the items loaded in the shopping cart, their prices, taxes established in current legislation and shipping costs if applicable.

The prices of the standards and books that appear in the various sections do not include taxes or shipping costs.

AENOR promotional codes consist of alphanumeric characters and can only be applied to online purchases, received through a specific offer and for a limited time. To apply your promotional code, you just have to enter it in step 2 of 4 of the purchase process on the website and click on "apply", after you have identified yourself and chosen the payment methods. Promo codes are not cumulative.

 

  • Credit or debit card (Visa, Mastercard) and PayPal.
  • Bank transfer. If you opt for this form of payment, you must first send AENOR a copy of the transfer by email to normas@aenor.com
  • The purchase invoice can be downloaded from the customer area, in my previous orders

In the case of clients of companies based abroad, the taxpayer identification number of the corresponding country (for example, in Argentina the CUIT), must be filled in the CIF/NIF - VAT field .

  • Direct download via the website in the Customer Area. In the customer area, which can only be accessed with a password and username, the products purchased will be available for a period of fifteen days from the date of purchase, as long as the payment has been accepted. Files in digital format are protected and in no case editable. Before purchasing them, it is important that the license of use is read and accepted as a prior step to purchase.
  • Shipping by courier. Products purchased on physical media are shipped by courier. The maximum delivery time in Spanish territory, from the acceptance of the order by AENOR, is:
  •  Approximately seven working days for all standards purchased through the store in paper format.
  • Approximately three days for books purchased through the store. Stocks of paper books are limited and their offer on the website does not imply availability within the indicated period. In the event that the requested book is not available, the customer is notified of the delay in receiving the order, which will be approximately seven working days. 

For the rest of the products that are not on the website, check availability and delivery time at normas@aenor.com.
