Energy performance of buildings — Sensible and latent heat loads and internal temperatures — Part 1:...
ISO 52017-1:2017 specifies the general assumptions, boundary conditions and equations for the calculation, under transient hourly or subhourly conditions, of the internal temperatures (air and operative) and/or the heating, cooling and humidification and dehumidification loads to hold a specific (temperature, moisture) set point, in a single building zone. No specific numerical techniques are…
Energy performance of buildings — Overarching EPB assessment — Part 1: General framework and procedu...
ISO 52000-1:2017 establishes a systematic, comprehensive and modular structure for assessing the energy performance of new and existing buildings (EPB) in a holistic way.
It is applicable to the assessment of overall energy use of a building, by measurement or calculation, and the calculation of energy performance in terms of primary energy or other energy-related metrics. It takes into account…
Energy performance of buildings — Energy needs for heating and cooling, internal temperatures and se...
ISO/TR 52016-2:2017 contains information to support the correct understanding and use of ISO 52016‑1 and ISO 52017‑1.
These documents give calculation methods for the assessment of:
- the (sensible and latent) energy load and need for heating and cooling, based on hourly calculations;
- the (sensible and latent) energy need for heating and cooling, based on monthly calculations (ISO…
Thermal performance of windows, doors and shutters — Calculation of thermal transmittance — Part 2: ...
ISO 10077-2:2017 specifies a method and gives reference input data for the calculation of the thermal transmittance of frame profiles and of the linear thermal transmittance of their junction with glazing or opaque panels.
The method can also be used to evaluate the thermal resistance of shutter profiles and the thermal characteristics of roller shutter boxes and similar components (e.g. blinds…
Energy performance of buildings — Indicators for partial EPB requirements related to thermal energy ...
The set of EPB assessment standards produces a great number of overall and partial EPB indicators as outputs, which can be used for different purposes. ISO 52018-1:2017 deals with the use as requirement of partial EPB indicators related to the fabric and related to the thermal balance of the building. Thermal balance aspects concern both the heating and cooling needs and the free floating…
Energy performance of buildings — Indicators, requirements, ratings and certificates — Part 1: Gener...
The set of EPB assessment standards produces a great number of overall and partial EPB indicators as outputs. ISO 52003-1:2017 provides general insight to both private parties and public regulators (and all stakeholders involved in the regulatory process) on how to make good use of these outputs for different purposes (post-processing).
ISO 52003-1:2017 describes the relation between the EPB…
Building components and building elements — Thermal resistance and thermal transmittance — Calculati...
ISO 6946:2017 provides the method of calculation of the thermal resistance and thermal transmittance of building components and building elements, excluding doors, windows and other glazed units, curtain walling, components which involve heat transfer to the ground, and components through which air is designed to permeate.
The calculation method is based on the appropriate design thermal…
Thermal performance of buildings — Heat transfer via the ground — Calculation methods
ISO 13370:2017 provides methods of calculation of heat transfer coefficients and heat flow rates for building elements in thermal contact with the ground, including slab‐on‐ground floors, suspended floors and basements. It applies to building elements, or parts of them, below a horizontal plane in the bounding walls of the building situated
- at the level of the inside floor surface, for slab‐…
Thermal bridges in building construction — Heat flows and surface temperatures — Detailed calculatio...
ISO 10211:2017 sets out the specifications for a three-dimensional and a two-dimensional geometrical model of a thermal bridge for the numerical calculation of
- heat flows, in order to assess the overall heat loss from a building or part of it, and
- minimum surface temperatures, in order to assess the risk of surface condensation.
These specifications include the geometrical…
Thermal performance of building components — Dynamic thermal characteristics — Calculation methods
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…
