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
method respectively.

ISO 11665-11:2016 describes radon-222 test methods for soil gas using passive and active in-situ sampling at depth comprised between surface and 2 m.
ISO 11665-11:2016 gives general requirements for the sampling techniques, either passive or active and grab or continuous, for in-situ radon-222 activity concentrations measurement in soil gas.
The radon-222 activity concentration in the soil can be measured by spot or continuous measurement methods (see ISO 11665‑1). In case of spot measurement methods (ISO 11665‑6), the soil gas sampling is active only. On the other hand, the continuous methods (ISO 11665‑5) are typically associated with passive soil gas sampling.
The measurement methods are applicable to all types of soil and are determined according to the end use of the measurement results (phenomenological observation, definition or verification of mitigation techniques, etc.) taking into account the expected level of the radon-222 activity concentration.
These measurement methods are applicable to soil gas samples with radon activity concentrations greater than 100 Bq/m3.
NOTE This part of ISO 11665 is complementary with ISO 11665‑7 for characterization of the radon soil potential.

ISO 11665-7:2012 gives guidelines for estimating the radon-222 surface exhalation rate over a short period (a few hours), at a given place, at the interface of the medium (soil, rock, laid building material, walls, etc.) and the atmosphere. This estimation is based on measuring the radon activity concentration emanating from the surface under investigation and accumulated in a container of a known volume for a known duration. This method is estimative only, as it is difficult to quantify the influence of many parameters in environmental conditions. ISO 11665-7:2012 is particularly applicable, however, in case of an investigation, a search for sources or a comparative study of exhalation rates at the same site. ISO 11665-7:2012 does not cover calibration conditions for the rate estimation devices.

ISO 13138:2012 specifies sampling conventions to define idealized samplers for estimating the deposition of non-volatile, non-hygroscopic, non-fibrous aerosols in five specific loci of the respiratory tract. The five loci consist of the anterior and posterior areas of the nasal passages, the ciliated and non-ciliated parts of the tracheobronchial area, and the alveolar (gas exchange) region.
The conventions are separated into three independent sampling efficiencies defined in terms of thermodynamic diameter characterizing the diffusive (Brownian) motion of sub-micrometre particles and four efficiencies in terms of aerodynamic diameter 0,1 μm characterizing deposition by impaction, interception or gravitational settling. Each conventional curve has been developed as an average of 12 deposition curves corresponding to 12 breathing conditions ranging from sitting to heavy exercise, male vs female, and breathing mode (mouth vs nasal breathing).

This International Standard is intended to provide a common reference to uncertainty estimation in air quality measurement, including measurements of ambient air, stack emission, indoor air and workplace atmospheres. It provides comprehensive guidance and specific
statistical procedures for uncertainty estimation in air quality measurement, implementing the general recommendations of the Guide to the Expression of Uncertainty in Measurement (GUM) to boundary conditions met in air quality measurement. Conditions considered include
measurands varying rapidly in time, hidden deviations caused by random changes of measuring conditions not corrected for, and the experimental designs used to keep random and systematic deviations under control. Experimental designs considered include calibration
procedures, intralaboratory and interlaboratory comparison procedures, drift control procedures, as well as the assessment of variances caused by hidden deviations. Guidance and statistical procedures provided by this International Standard are intended to be applicable
by technical experts in routine air quality measurement, as well as in development, validation and standardisation of air quality measurement methods.

The European Directive on ambient air quality and cleaner air for Europe (2008/50/EC; AQD) identifies different uses for modelling: Assessment, planning, forecast and source apportionment (SA). This document addresses source apportionment modelling and specifies performance tests to check whether given criteria for receptor oriented source apportionment models (RM) are met. The scope of the tests set out in this document is the performance assessment of SA of particulate matter using RM in the context of the European Directives 2004/107/EC and AQD, including the Commission Implementing Decision 2011/850/EU of 12 December 2011. The application of RM does not quantify the spatial origin of particulate matter; hence, this document does not test spatial SA.
This document addresses RM users: practitioners of individual source apportionment studies as well as participants and organizers of source apportionment intercomparison studies. This document is suitable for the evaluation of results of a specific SA modelling system with respect to reference values (a priori known or calculated on the basis of intercomparison participants' values) in the following application areas:
-   Assessment of performance and uncertainties of a modelling system or modelling system set up using the indicators laid down in this document.
-   Testing and comparing different source apportionment outputs in a specific situation (applying an evaluation data set) using the indicators laid down in this document.
-   QA/QC tests every time practitioners run a modelling system.
It should be noted for clarity that the procedures and calculations presented in this document cannot be used to check the performance of a specific SA modelling result without having any a priori reference information about the contributions of sources/source categories.
NOTE   The application of this document implies that the intercomparison is organized and coordinated by an institution with the necessary technical capabilities and independence; the definition of which is beyond the scope of this document.
The principles of RM are summarized in Annex A. An overview of uncertainty sources and recommendations about steps to follow in SA studies are provided in Annex B and Annex C. For further information about SA methodologies, refer to e.g. [1; 2; 3].
There are methodologies different from RM which are widely used to accomplish SA, e.g. source oriented models. These other methodologies cover aspects of SA which are required in the AQD and are not addressed by RM (e.g. allocation of pollutants to geographic emission areas). Performance assessment of such methodologies is out of the scope of this document.

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 method respectively.

ISO 16362:2005 specifies sampling, cleanup and analysis procedures for the quantitative determination of low volatility (particle-bound) polycyclic aromatic hydrocarbons (PAHs) in ambient air. For sampling, a low-volume or a medium/high-volume sampling device may be used. Sampling times between 1 h and 24 h are possible. The sampling volume flow rates can range from 1 m/h to 4 m/h ("low volume sampler") or from 10 m/h to about 90 m/h ("medium/high-volume sampler"). In any case, the linear face velocity at the collection filter should range between about 0,5 m/s and 0,9 m/s. The method has been validated for sampling periods up to 24 h. The detection limits for single PAHs and the standard deviations resulting from duplicate measurements are listed. ISo 16362:2005 describes a sampling and analysis procedure for PAH that involves collection from air onto a filter followed by analysis using high performance liquid chromatography usually with fluorescence detector (FLD). The use of a diode array detector (DAD) is possible. The combination of both detector types is also possible. Total suspended particulate matter is sampled. Generally, compounds having a boiling point above 430 °C (vapour pressure less than 10-9 kPa at 25 °C, e.g. chrysene, benz[a]anthracene) can be collected efficiently on the filter at low ambient temperatures (e.g. below 10 °C). In contrast, at higher temperatures (above 30 °C, see also ISO 12884[1]), only PAHs having boiling points above 475 °C (vapour pressure less than 10-10 kPa at 25 °C) are determined quantitatively.

ISO 11222:2002 provides a method for the quantification of the uncertainty of a time average of a set of air quality data obtained at a specified location over a defined averaging time period. The method is applicable to air quality data obtained by continuous or intermittent monitoring by means of a specified measuring system. The uncertainty of the time average depends on both the uncertainty of the measurement results and the uncertainty due to incomplete time coverage of the data set.  
ISO 11222:2002 is only applicable if  
the set of air quality data used to calculate the time average is representative of the temporal structure of the measurand over the defined time period,
appropriate information on the uncertainty of the measurement results is available, and
the measurement results have all been obtained at the same location.  
ISO 11222:2002 implements recommendations of the Guide to the Expression of Uncertainty in Measurement (GUM).

ISO 16017-2:2003 gives general guidance for the sampling and analysis of volatile organic compounds (VOCs) in air. It is applicable to indoor, ambient and workplace air.
ISO 16017-2:2003 is applicable to a wide range of VOCs, including hydrocarbons, halogenated hydrocarbons, ester, glycol ethers, ketones and alcohols. A number of sorbents are recommended for the sampling of these VOCs, each sorbent having a different range of applicability. Very polar compounds generally require derivatisation; very low boiling compounds are only partially retained by the sorbents and can only be estimated qualitatively. Semi-volatile compounds are fully retained by the sorbents, but may only be partially recovered.
ISO 16017-2:2003 is applicable to the measurement of airborne vapours of VOCs in a concentration range of approximately 0,002 mg/m3 to 100 mg/m3 individual organic for an exposure time of 8 h, or 0,3 g/m3 to 300 g/m3 individual organic for an exposure time of four weeks.
The upper limit of the useful range is set by the sorptive capacity of the sorbent used and by the linear dynamic range of the gas chromatograph column and detector or by the sample splitting capability of the analytical instrumentation used. The lower limit of the useful range depends on the noise level of the detector and on blank levels of analyte and/or interfering artefacts on the sorbent tubes. Artefacts are typically sub-nanogram for well-conditioned Tenax GR and carbonaceous sorbents, carbonized molecular sieves and pure charcoals; at low nanogram levels for Tenax TA and at 5 ng to 50 ng levels for other porous polymers.
