Full title and description

STB DIN EN ISO 13370 E 2015-06 — Thermal performance of buildings — Heat transfer via the ground — Calculation methods. This entry refers to a DIN/EN draft version issued in June 2015 (prEN / DIS stage) and the corresponding ISO series addressing methods to calculate heat transfer coefficients and heat flow for building elements in contact with the ground (slab‑on‑ground floors, suspended floors and basements).

Abstract

Provides calculation procedures for the steady‑state (annual average) and seasonal (monthly) components of heat flow between a building and the ground, and methods for deriving heat transfer coefficients for elements below the horizontal plane of the building envelope (floor slabs, suspended floors, heated and unheated basements). The standard places these methods within the EPB modular framework (see ISO 52000‑1).

• Number of pages: Draft DIN EN ISO 13370 (2015 draft) listed as 112 pages; the published ISO 13370:2017 edition is listed as 49 pages (national EN/EN ISO translations and national publications may show different page counts).

Scope

Specifies calculation methods for heat transfer coefficients and heat flow rates for building elements in thermal contact with the ground. Applies to elements or parts of them located below a horizontal plane in the bounding walls — e.g., at the level of the inside floor surface for slab‑on‑ground, suspended floors and unheated basements, and at the external ground surface for heated basements. Includes steady‑state (annual average) and monthly seasonal variation calculations; dynamic simulation application is addressed in an annex.

Key topics and requirements

• Calculation of heat transfer coefficients for elements in contact with soil/ground.
• Annual average (steady‑state) and monthly seasonal heat flow rate procedures.
• Application to slab‑on‑ground floors, suspended floors, unheated and heated basements.
• Normative references and positioning within EPB modular framework (links to ISO 52000‑1 and related thermal‑bridge/heat‑flow methods).
• Annex material for dynamic simulation programme application (where applicable).

Typical use and users

Used by building physicists, energy assessors, architects, structural and HVAC engineers, standards committees and software developers that implement thermal‑performance or whole‑building energy models. Typical applications include energy performance calculations, heat‑loss estimates for foundation and slab elements, and inputs to EPB/energy‑rating assessments.

Related standards

Normative and related documents commonly referenced with ISO 13370 include ISO 52000‑1 (EPB framework), ISO 10211 (detailed thermal‑bridge calculations), ISO 14683 (simplified linear thermal transmittance methods and default values) and other EPB series standards; national EN/EN ISO implementations (EN ISO 13370:2017 and national adoptions) align with the ISO text.

FAQ

Q: What is this standard?

A: A (DIN/EN/ISO) standard that defines calculation methods for heat transfer between buildings and the ground (slabs, suspended floors, basements). The title and core content derive from ISO 13370; the item labelled "2015‑06" refers to a DIN/EN draft stage published in mid‑2015.

Q: What does it cover?

A: Procedures to calculate steady‑state (annual average) and seasonal (monthly) heat flows and transfer coefficients for building elements in contact with the ground; guidance on boundary definitions (floor surface level vs external ground level) and an annex addressing dynamic simulation use.

Q: Who typically uses it?

A: Engineers, architects, building physicists, energy assessors, software vendors for building simulation and standards bodies that adopt ISO text nationally (e.g., EN or DIN versions).

Q: Is it current or superseded?

A: The DIN/EN draft dated 2015‑06 is shown in catalogue records as withdrawn/replaced; the final international edition is ISO 13370:2017 (published June 2017) and is the authoritative published edition of the methods. National EN/EN‑ISO adoptions followed the 2017 publication.

Q: Is it part of a series?

A: Yes — ISO 13370 is part of the set of EPB (energy performance of buildings) related standards and links into the modular EPB framework (ISO 52000‑1) and to other thermal‑bridge and heat‑flow documents (for example ISO 10211 and ISO 14683).

Q: What are the key keywords?

A: Heat transfer via the ground, thermal performance, slab‑on‑ground, basement, heat flow rate, heat transfer coefficient, EPB, ISO 13370.
