— establishing procedures and templates for the conversion from calculated energy performance for heating or cooling into a classification (rating):
— if appropriate, establishing procedures and templates for the conversion from the day-lighting performance of the fenestration system (characterized by a daylight potential) into a classification (rating).
6.1.3 Part 2: Calculation of the energy performance of a specific fenestratlon system
The user applying this International Standard shall calculate the energy performance of a specific fenestration system in accordance with the steps outlined here. The energy rating can be carried out either in a specific orientation or as a weighted average of a number of orientations.
The calculation procedure consists of four steps. Each step involves the gathering of a specific set of input data, followed by specific “pre-processing calculations.
Figure 1 gives a detailed schematic overview of the calculation steps and the data that are needed as input:
the main sources of the data are also given. The detailed procedures are given in 6.2 to 6.5. Only the general principles are provided here.
Step 1: ClImate. Input data: Select appropriate nationally or regionally representative climate data, such as external temperature and the intensity of solar radiation incident on the fenestration system with given orientation and tilt.
Step 2: Building. Input data: Select appropriate data on one (or a set of) nationally specified reference building(s) and reference occupancy, including reference services (heating, cooling and ventilation) and their control.
Step 3: Fenestration system. Input data: Obtain the fenestration system properties: thermal transmittance, solar transmittance, heat transfer due to air leakage, and daylight potential.
Step 4: Calculation procedure. From the building-related data (step 2), together with the fenestration system data (step 3) and the climate data (step 1), the gain and loss utilization factors for heating and cooling respectively are calculated for monthly and seasonal methods. For the hourly method, the energy balance of the reference building is calculated each time a fenestration product is being evaluated.
Finally, with all input data available and all pre-processing” calculations done, the energy performance of the fenestration system can be calculated for the heating mode, F H,w’ arid for the cooling mode, F C.w’ separately. This procedure is given in Clause 5.
It may be decided at a national level to present one annual energy performance value, combining the value for heating with the value for cooling.
NOTE The energy performance value can be used as a basis for classification, using a continuous or discrete scale and benchmarks, e.g. in a way similar to EN 15217 for the energy pefomiance classification for buildings.ISO 18292-2011 pdf free download.
