Process information

Key Data Set Information
Location	IE
Geographical representativeness description	The main market for the Mannok Aircrete blocks is housing and commercial buildings. The blocks are supplied to the markets in Northern Ireland, Great Britain and the Republic of Ireland.
Reference year	2024
Name	Aircrete block High Ten
Use advice for data set	This LCA covers the Product (A1, A2 and A3), Transport to site (A4), Construction Process (A5), Use (B1 to B7), End of Life (C1 to C4) and Benefits/loads beyond the system boundary (D) Stages, as indicated above. This is termed: "Cradle to grave, and module D". Specific details of the Product Stage (A1 to A3) are illustrated in the flow diagram below.
Technical purpose of product or process	The Aircrete blocks are high performance thermal blocks which are precision manufactured using autoclaved aerated concrete (AAC). They are lightweight and provide superior thermal performance. They are used in housing and commercial/industrial construction applications, for construction of external walls, rising foundation walls, internal partition walls, and party walls. The Aircrete thermal blocks are manufactured in accordance with I.S. EN 771-4:2011+A1:2016, Specification for masonry units - Part 4: Autoclaved aerated concrete masonry units. Further technical details on the blocks can be found at: https://mannokbuild.com/aircrete-thermal-blocks/what-are-aircrete-thermal-blocks/
General comment on data set	Data quality: The data Quality Levels, according to Table E.1 of EN 15804 +A2, Annex E, are: Geographical representativeness: Very good: the production location of the blocks lies within the region for which the relevant Ecoinvent (version 3.8) environmental records have been selected. Time representativeness: Very good: the data relating to the manufacturing of the blocks, and the data relating to the background processes for environmental impacts are recent (<2 years). The LCA dataset for the cement is from 2021 and is of the specific cement used in production. Technical representativeness: Very good: the processes and energies used in the process have been modelled exactly as described by Mannok Aircrete blocks and are based directly on the production data supplied by Mannok for the Aircrete block production. Allocation: The measurement of environmental impacts in this EPD uses the LCIA methodologies recommended for PEF 3.1. In this EPD, the waste processes are allocated in the relevant module. In the case of the use of secondary materials or energy recovered from secondary fuels, the system boundary between the system under study and the previous system (providing the secondary materials) is set where outputs of the previous system, e.g. materials, products, building elements or energy, reach the end-of-waste state. The modularity and the polluter payer principles have been followed. Allocation of energies such as diesel, propane and electricity types and amounts to the various manufacturing processes has been provided by the manufacturer, along with production waste and direct emissions; allocation of impacts to the products is based on the product composition mass. Cut-off criteria: All relevant inputs and outputs - like emissions, energy and materials - have been taken into account in this LCA, and in accordance with EN15804+A2:2019. The study covers at least 95% of the materials and energy per module and at least 99% of the total use of materials and energy of each unit process. Long term emissions have been excluded from the study.

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.
