TP083 - Pravilnik o učinkoviti rabi energije v stavbah

This standard provides a systematic, comprehensive and modular overall structure on the integrated energy performance of buildings, in order to ensure consistency among all CEN standards required to calculate the energy performance of buildings according to the EPBD (2010/31/EU).
This standard handles the framework of the overall energy performance of a building, covering inter alia:
a)   common terms, definitions and symbols;
b)   building and system boundaries;
c)   building partitioning;
d)   methodology for calculating the energy performance of a building (set of overall formulae on energy used, delivered, produced and/or exported at the building site and near-by);
e)   set of overall formulae and input-output relations, linking the various elements relevant for the assessment of the overall energy performance of buildings which are treated in separate standards;
f)   general requirements to standards dealing with partial calculations;
g)   general rules in setting out alternative calculation routes according to the calculation scope and requirements;
h)   rules for the combination of different partitioning;
i)   performance indicators;
j)   methodology for measured energy performance assessment.

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 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.
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.

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 European Standard specifies a flame atomic absorption spectrometric method for the determination of titanium in steels and cast irons. The method is applicable to non-alloyed and alloyed steels and cast irons with titanium contents of 0,01 % to 1,0 % (m/m).
