    ISO 13370:2017 Thermal performance of buildings — Heat transfer via the ground — Calculation methods

    In order to ensure that buildings are comfortable and energy efficient, it is important to understand how heat travels through them. The ground is one of the main ways that heat is transferred, so the ISO 13370:2017 standard provides guidance on how to calculate the thermal performance of buildings with this in mind. This article will provide an overview of the standard and its key provisions.

    What is ISO 13370:2017 ?

    ISO 13370:2017 is an international standard that provides guidance on the calculation of the heat transfer via the ground. It is based on the ISO 8990 standard.

    The standard applies to buildings with a floor area of less than 400 m². It can be used for new buildings or for retrofitting existing buildings.

    The standard provides two methods for calculating the heat transfer via the ground:

    • The thermal resistance method
    • The thermal conductivity method

    The thermal resistance method is suitable for estimating the heat transfer in both homogeneous and inhomogeneous soils. The thermal conductivity method is more accurate but it can only be used in homogeneous soils.

    If you are planning to use the ISO 13370:2017 standard in your project, you should be aware of its limitations. For example, it does not consider the effects of moisture on the heat transfer.

    What are the requirements for ISO 13370:2017

    The standard provides requirements and guidance for the calculation of the thermal performance of buildings with respect to heat transfer via the ground. The calculations are based on physical models that take into account the type of soil and the building’s foundation system.

    The standard is applicable to all types of building foundations, including those with and without insulation. It can be used for both new buildings and existing buildings that are being retrofitted with insulation.

    ISO 13370:2017 is not applicable to buildings with a heated basement or crawl space. This type of building is not common in most countries.

    The standard provides two methods for calculating the thermal performance of a building: the steady-state method and the transient method. The steady-state method is suitable for most buildings, while the transient method is more accurate but requires more data and calculations.

    ISO 13370:2017 does not provide requirements or guidance on how to select the appropriate calculation method for a particular building. This decision should be made by the engineer or designer based on their experience and knowledge of the building and its location.

    What are the benefits of ISO 13370:2017 ?

    The benefits of ISO 13370:2017 are many and varied, but some of the most notable include:

    • Improved thermal performance of buildings
    • More accurate calculation methods
    • Greater understanding of heat transfer via the ground
    • Better decision making when it comes to building design
