NOTE The thermal transmittance of the whole fenestration system, including glazing, frame and solar shading device,. The quantities which are specific to this. In this International Standard, the energy performance values are calculated in kilowatt hours per square.
Energy performance of the fenestration system is expressed through energy performance indices, P , one. P is the fenestration heating energy performance index, expressed in kilowatt hours per square metre,. The energy need of the reference building caused by the fenestration system is considered to be independent.
NOTE For the hourly method, separating cooling and heating components is a complex task, which can involve. NOTE For the dynamic method, separating cooling and heating components is a complex task which can involve.
When calculating P using hourly methods, it is recommended that changes in U-values due to the exposure. It is not therefore. It is necessary to use the same building assumptions and boundary. Hourly calculation. For the evaluation of the energy performance for fenestration systems, all data used shall be for the same tilt.
The procedure presented in this International Standard includes two different parts, 6. The following actions shall be performed once only by the responsible bodies as part of the overall preparation. The user applying this International Standard shall calculate the energy performance of a specific fenestration. The energy rating can be carried out either in a specific. The calculation procedure consists of four steps.
Each step involves the gathering of a specific set of input. Figure 1 gives a detailed schematic overview of the calculation steps and the data that are needed as input;. The detailed procedures are given in 6. Only the general. Step 1: Climate. Input data: Select appropriate nationally or regionally representative climate data, such as.
Step 2: Building. Input data: Select appropriate data on one or a set of nationally specified reference. Step 3: Fenestration system.

For the hourly method, the energy balance of. It may be decided at a national level to present one annual energy performance value, combining the value for.
NOTE The energy performance value can be used as a basis for classification, using a continuous or discrete scale. The fenestration energy performance for heating is the annual sum of the monthly contributions or the. For the hourly method, the fenestration product energy performance for. The contributions from the fenestration to the energy needs for space heating are calculated on a monthly. The calculation includes: - different types of glazing, e. ISO specifies a detailed method, based on spectral data of the transmittance and reflectance of the constituent materials solar protection devices and the glazing , to determine the total solar energy transmittance, the total light transmittance and other relevant solar-optical data of the combination.
If spectral data are not available, the methodology can be adapted to use integrated data. ISO 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.
ISO 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 b The set of EPB assessment standards produces a great number of overall and partial EPB indicators as outputs, which can be used for different purposes.
ISO deals with the use as requirement of partial EPB indicators related to the fabric and related to the thermal balance of the building. Thermal balance aspects concern both the heating and cooling needs and the free floating temperatures, especially with respect to overheating or too cold indoor temperatures.
