Technical purpose of product or process Supply and extract air unit with switchover option for secondary air operation, including cross flow heat recovery unit and heat exchanger for installation under the ceiling. Ready-to-operate decentralised ventilation unit that provides good comfort levels and is used for the ventilation of internal spaces such as classrooms, conference rooms and day nurseries. For more information see: https://www.trox.de/en/ceiling-units/x-cube-schoolair-d%C2%A0%C2%A0-5bc4e1e85687c356. Ventilation units for installation on the façade in the ceiling area. Please note: The ceiling ventilation unit variant described is equipped with an integrated individual room control for independent classroom operation. The supplied controllers contain the parameters of the standard control for self-sustaining operation according to our control description. Ventilation unit for schools – ceiling installation – master unit TROX X-CUBE/SCHOOLAIR-D ventilation unit for ceiling installation, for supply and extract air function, and switchover option to secondary air mode (depending on room air quality), heat recovery and heating function for installation in the ceiling area. This EPD includes the environmental data of the product series Schoolair-D. The following represents a specific dataset of the most sold variant in the declared sales year (SAD-HV-0-2-1-BB-W/3363x410x1030/P1-C3-MA-T-0-0-Z-A-HV-R-0.4).

General comment on data set Data quality: Specific data for the product composition are provided by the manufacturer. The data represent the production of the declared product and were collected for EPD development in the year of study. Background data is based on EPDs according to EN 15804 and different LCA databases. The data quality of the raw materials in A1 is presented in the table below. Allocation: The allocation is made in accordance with the provisions of EN 15804. Energy, water and waste production in-house is allocated equally among all products through mass allocation. Effects of primary production of recycled materials is allocated to the main product in which the material was used. The recycling process and transportation of the material is allocated to this analysis. Cut-off criteria: All major raw materials and all the essential energy is included. The production processes for raw materials and energy flows with very small amounts (less than 1%) are not included. These cut-off criteria do not apply for hazardous materials and substances.

1This impact category deals mainly with the eventual impact of low dose ionizing radiation on human health of the nuclear fuel cycle. It does not consider effects due to possible nuclear accidents, occupational exposure nor due to radioactive waste disposal in underground facilities. Potential ionizing radiation from the soil, from radon and from some construction materials is also not measured by this indicator.
2The results of this environmental impact indicator shall be used with care as the uncertainties on these results are high or as there is limited experiences with the indicator.
