performance of fluid heating solar collectors. The test methods are applicable for laboratory testing
and for in situ testing.
This document is applicable to all types of fluid heating solar collectors, air heating solar collectors,
hybrid solar collectors co-generating heat and electric power, as well as to solar collectors using

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.

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 document 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 52016-1);
— the internal temperature, based on hourly calculations; and
— the design (sensible and latent) heating and cooling load, based on hourly calculations.
This document does not contain any normative provisions.
NOTE A description of the rationale behind the reorganization of the cluster of strongly related and partly
overlapping ISO and CEN standards is given in Annex H.

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.
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 new international standard will provide ways to express the energy performance and energy performance requirements at the level of the building as such, the building envelope and the building elements.

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.

ISO 14683:2007 deals with simplified methods for determining heat flows through linear thermal bridges which occur at junctions of building elements.
ISO 14683:2007 specifies requirements relating to thermal bridge catalogues and manual calculation methods.
Default values of linear thermal transmittance are given in Annex A for information.

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

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

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.

features and to fabric features. It also provides tables for regulators to report their choices in a uniform
manner. This document provides many background considerations that can help both private actors
and public authorities, and all stakeholders involved, to take informed decisions.
This document does not contain any normative provision.

This document 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 boundaries and subdivisions of the model, the thermal
boundary conditions, and the thermal values and relationships to be used.
This document is based upon the following assumptions:
— all physical properties are independent of temperature;
— there are no heat sources within the building element.
This document can also be used for the derivation of linear and point thermal transmittances and of
surface temperature factors.

in the context of the modular structure as set out in ISO 52000-1.

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.
