This document provides a transparent framework for reporting on the choices related to the procedure
to determine primary energy factors (PEFs) and CO2 emission coefficients for energy delivered to and
exported from the buildings as described in EN ISO 52000-1.
This document specifies the choices to be made to calculate the PEF(s) and CO2 emission coefficients
related to different energy carriers. PEFs and CO2 emission coefficients for exported energy can be
different from those chosen for delivered energy.
This document is primarily intended for supporting and complementing EN ISO 52000-1, as the latter
requires values for the PEFs and CO2 emission coefficients to complete the EPB calculation. But it can also
be used for other applications.
NOTE The CO2 emission coefficients allow calculating greenhouse gas emissions. According to the choices
made, the CO2 emission coefficients represent only CO2 emissions or also other greenhouse gases.
Table 1 shows the position (marked by “X”) of this document within the modular structure as set out in
EN ISO 52000-1.
The modules represent EPB standards, although one EPB standard may cover more than one module and
one module may be covered by more than one EPB standard, for instance a simplified and a detailed

ISO 18523-2:2018 specifies the formats to present the schedule and conditions of zone and space usage (referred to as input data of energy calculations) for residential buildings.
The schedule and conditions include schedules of occupancy, operation of technical building systems, ventilation rates, hot water usage, usage of appliances and internal heat gains due to occupancy, lighting and appliances. The schedule and conditions for lighting are applicable to fixed installed lighting fixtures.
ISO 18523-2:2018 also gives categories of residential building, zone and space according to differentiating schedule and condition. For residential buildings or its housing units which contain any category of space or zone of non-residential buildings, ISO 18523‑1 applies.
Depending on necessary minuteness of the energy calculation, different levels of schedule and condition from the view point of time and space averaging are specified.
The values and categories for the schedule and condition are included informatively.
NOTE The schedule and condition in this document is basically different from assumptions in order to determine the size of technical building systems in the process of design, where possible largest or smallest values are assumed. Instead, most usual and average values, which are assumed for the building energy calculation, are dealt with in this document.

This document describes a building enclosure commissioning process to achieve a well performing, durable and maintainable building enclosure. This document includes procedures, methods and documentation requirements describing the application of the commissioning process to a building enclosure at each phase of a project. These project phases span from predesign through owner occupancy and operation. This process is referred to throughout this document as building enclosure commissioning (BECx). This document applies to new building construction and building re-commissioning. This document is for use by an owner, commissioning provider, building developer, owner's representative, construction manager, architect, contractor, and/or consultant, etc. Its purpose is to determine and complete the required tasks and activities to deliver a building enclosure which meets the performance requirements of the owner. Requirements for the project are established by the owner and/or commissioning provider (CxP). This document identifies steps necessary to perform a building enclosure risk analysis. The analysis will result in tasks that define the level of BECx, commensurate with the owner's tolerance for risk associated with building enclosure performance. The BECx process covered by this document is applicable to an individual assembly, a combination of assemblies or a whole enclosure assembly. For example, an individual assembly can be the fenestration, the air barrier or the thermal insulation. A combination of assemblies would include the fenestration, the air barrier and the complete heat transfer system, (e.g. both the insulation and roof assembly). A whole building enclosure assembly would include all heat, air and moisture control layers of the building enclosure, on all six sides of the building. This document describes requirements for any third-party consultants and/or building enclosure commissioning providers (BECxP) to document their technical qualifications, independence and knowledge of the BECx process, including their education, training, and experience.

This document 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, this document is not applicable to
building materials or to unfinished building components.
The definitions given in this document 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 this document within the set of EPB standards
in the context of the modular structure as set out in ISO 52000-1.

This document 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 conductivities or design thermal
resistances of the materials and products for the application concerned.
The method applies to components and elements consisting of thermally homogeneous layers (which
can include air layers).
This document also provides an approximate method that can be used for elements containing
inhomogeneous layers, including the effect of metal fasteners, by means of a correction term given in
Annex F. Other cases where insulation is bridged by metal are outside the scope of this document.

Revision of EN ISO 10077-2:2012
This part of ISO 10077 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).
This part of ISO 10077 also gives criteria for the validation of numerical methods used for the calculation.
This part of ISO 10077 does not include effects of solar radiation, heat transfer caused by air leakage or three-dimensional heat transfer such as pin point metallic connections. Thermal bridge effects between the frame and the building structure are not included.
No change to the scope is expected. There will be editorial revision (new structure) in the context of Mandat M/480 and also technical revison of the existing standard.

This document specifies a method and provides conventions for the calculation of the steady‐state
transmission and ventilation heat transfer coefficients of whole buildings and parts of buildings. It is
applicable both to heat loss (internal temperature higher than external temperature) and to heat gain
(internal temperature lower than external temperature). For the purpose of this document, the heated
or cooled space is assumed to be at uniform temperature.
Annex C provides a steady‐state method to calculate the temperature in unconditioned spaces adjacent
to conditioned spaces.

This European Standard specifies a simplified method based on the thermal transmittance and total solar energy transmittance of the glazing and on the light transmittance and reflectance of the solar protection device to estimate the total solar energy transmittance of a solar protection device combined with glazing.
The method applies to all types of solar protection devices parallel to the glazing such as louvre, venetian or roller blinds. The position of the solar protection device can be interior, exterior or between single panes in a dual glazing system. It is applicable when the total solar energy transmittance of the glazing is between 0,15 and 0,85. Venetian or louvre blinds are assumed to be adjusted so that there is no direct solar penetration. It is assumed that for external solar protection devices and for integrated solar protection devices, the space between the solar protection devices and the glazing is unventilated and for internal solar protection devices this space is ventilated.
The resulting g-values of the simplified method given here are approximate and their deviation from the exact values lie within the range between +0,10 and -0,02. The results generally tend to lie on the safe side for cooling load estimations. The results are not intended to be used for calculating beneficial solar gains or thermal comfort criteria. The simplified method is based on the normal incidence of radiation and does not take into account either the angular dependence of transmittance and the reflectance or the differences of spectral distribution.
This standard can be applied when the solar transmittance and solar reflectance of the solar protection devices are within the following ranges:
0  e,B  0,5 and 0,1  e,B  0,8
For reflectance and transmittance values outside these ranges EN 13363-2 [1] applies.
An allowance can be made for this fact when applying the method. For cases not covered by the method given in this standard more exact calculations based on the optical properties (in general the spectral data) of glass and solar protection device can be carried out in accordance with EN 13363-2 [1].
No change to the scope is expected. There will be editorial revision (new structure) in the context of Mandate M/480 and maybe minor technical changes due to inconsistency to other standards under Mandate M/480

This new international standard will, in two parts, integrate EN 15265, EN 15255, EN-ISO 13791 and EN-ISO 13792.
Depending on the development, the split between part 1 and part 3 will be between a detailed method(s) (part 1) and simple method(s) (part 3).
This standard will contain a consistent and integrated set of requirements and additional descriptions of the thermal balance model for the hourly calculation of the energy needs for heating and cooling, the heating and cooling loads and indoor temperature in a thermal zone of a building. It will be directly usable by ISO 52016-1 for the calculation of the energy needs and by other EPB standards (e.g. from CEN/TC 156) dealing with needs, loads or indoor (e.g. summer) temperature calculations.

This document 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‐on‐ground floors, suspended floors and unheated
basements;
In some cases, external dimension systems define the boundary at the lower surface of the floor slab.
— at the level of the external ground surface, for heated basements.
This document includes calculation of the steady‐state part of the heat transfer (the annual average rate
of heat flow) and the part due to annual periodic variations in temperature (the seasonal variations of
the heat flow rate about the annual average). These seasonal variations are obtained on a monthly basis
and, except for the application to dynamic simulation programmes in Annex D, this document does not
apply to shorter periods of time.

This document specifies a detailed method, based on the spectral transmission data of the materials, comprising the solar protection devices and the glazing, to determine the total solar energy transmittance and other relevant solar-optical data of the combination. If spectral data are not available the methodology can be adapted to use in-tegrated data.
The method is valid for all types of solar protection devices parallel to the glazing such as louvres, or venetian, or roller blinds. The blind may be located internally, externally, or enclosed between the panes of the glazing. Ventilation of the blind is allowed for in each of these positions in determining the solar energy absorbed by the glazing or blind components, for vertical orientation of the glazing.
The blind component materials may be transparent, translucent or opaque, combined with glazing components with known solar transmittance and reflectance and with known emissivity for thermal radiation.
The method is based on a normal incidence of radiation and does not take into account an angular dependence of transmittance or reflectance of the materials. Diffuse irradiation or radiation diffused by solar protection devices is treated as if it were direct. Louvres or venetian blinds are treated as homogenous materials by equivalent solar optical characteristics, which may depend on the angle of the incidence radiation. For situations outside the scope of this document; ISO 15099 covers a wider range of situations.
The document also gives certain normalised situations, additional assumptions and necessary boundary conditions.
No change to the scope is expected. There will be editorial revision (new structure) in the context of Mandate M/480 and maybe minor technical changes due to inconsistency to other standards under Mandate M/480
