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.

ISO 18523-1:2016 specifies the formats to present schedule and condition of building, zone and space usage, which is to be referred to as input data of energy calculations for non-residential buildings.
The schedule and condition include schedules of occupancy, operation of technical building systems, ventilation rate, hot water usage and internal heat gains due to occupancy, lighting and equipment.
ISO 18523-1:2016 also gives categories of building, zone and space according to differentiating schedule and condition.
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 given in annexes for more information for the application when the users of this document do not have detailed information on the values and categories for the schedule and condition.
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 values are to be 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.

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 International Standard sets out ways of expressing the overall energy performance of a building. This includes an overall numerical energy performance indicator and classes against benchmarks. It also includes ways of expressing energy performance requirements. Furthermore, methods for energy performance certification of buildings are included.
This standard provides different (alternative) options, including both absolute indicators, such as energy performance per unit of floor area, and relative indicators, such as energy performance compared to the energy performance of a reference building (notional building approach). The rationale for each option, examples and all informative procedures will be provided in the accompanying technical report (EN ISO/TR 52003-2). This International Standard does not include numerical indicators at system or component level (these will be covered by EN ISO 52017-1 (building fabric and building elements) and similar standards on technical building systems.

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

The work concerns revision of existing standard EN ISO 13790. The scope will change. This revised international standard will provide calculation methods for assessment of the sensible and latent energy needs for space heating and cooling of a residential or a non-residential building, or a part of it, referred to as "the building". This method calculates, for a thermal zone in a building, the sensible and latent thermal energy needs based on the balance between the heat and moisture transfer by transmission and ventilation and the internal and solar heat gains. The energy needs are calculated by an hourly or monthly method. The hourly calculation method will be described in EN ISO 52017-1 (upgraded version of simple hourly method). The monthly method will be given in this standard including procedures how to derive monthly correlation coefficients from hourly calculations. The following input values and boundary conditions are obtained from other standards in the EPB series: overall routing of the energy performance calculation; occupancy patterns and conditions of use; thermal zoning of the building; environment conditions, thermal, dynamic (mass) and solar characteristics of building elements and their junctions; air infiltration and ventilation and ventilation system characteristics. Moisture absorption and desorption in building elements will not be considered. Because some of the characteristics that are input for the calculation are also dependent on the thermal balance calculation, many interactions will have to be accounted for at the level of each time step. The standard will contain simplified approaches for the energy balance in adjacent spaces that are not heated or cooled, including sunspaces

This European Standard covers energy performance calculation of mechanical ventilation systems with integrated heating/cooling generation, including domestic hot water production, using a monthly or seasonal calculation interval or a bin method. It takes into account the generation (air handling unit) and distribution (duct system) parts. It does not cover the emission part (calculation of the required volume flow rates and/or supply air conditions), which is covered in the M5-5 standard. It does not include humidification and dehumidification. This method is focussed on small, packaged ventilation systems, typically used in residential buildings, although the application is not restricted on the basis of building or space use type.
A calculation method for mechanical ventilation and air conditioning systems, including humidification and dehumidification, using an hourly calculation interval or a bin method, is provided in a separate standard, EN 16798 5 1.
Table 1 shows the relative position of this standard within the set of EPB standards in the context of the modular structure as set out in EN ISO 52000 1.
NOTE 1   In CEN ISO/TR 52000 2, the same table can be found, with, for each module, the numbers of the relevant EPB standards and accompanying technical reports that are published or in preparation.
NOTE 2   The modules represent EPB standards, although one EPB standard might cover more than one module and one module might be covered by more than one EPB standard, for instance a simplified and a detailed method respectively. See also Clause 2 and Tables A.1 and B.1.

This document specifies methods for the calculation of the thermal transmittance of windows and
pedestrian doors consisting of glazed and/or opaque panels fitted in a frame, with and without shutters.
This document allows for
— different types of glazing (glass or plastic; single or multiple glazing; with or without low emissivity
coatings, and with spaces filled with air or other gases),
— opaque panels within the window or door,
— various types of frames (wood, plastic, metallic with and without thermal barrier, metallic with
pinpoint metallic connections or any combination of materials), and
— where appropriate, the additional thermal resistance introduced by different types of closed shutter
or external blind, depending on their air permeability.
The thermal transmittance of roof windows and other projecting windows can be calculated according
to this document, provided that the thermal transmittance of their frame sections is determined by
measurement or by numerical calculation.
Default values for glazing, frames and shutters are given in the annexes. Thermal bridge effects at the
rebate or joint between the window or door frame and the rest of the building envelope are excluded
from the calculation.
The calculation does not include
— effects of solar radiation (see standards under M2-8),
— heat transfer caused by air leakage (see standards under M2-6),
— calculation of condensation,
— ventilation of air spaces in double and coupled windows, and
— surrounding parts of an oriel window.
The document is not applicable to
— curtain walls and other structural glazing (see other standards under M2-5), and
— industrial, commercial and garage doors.

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.
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.
