Standard
EN 15978 — Assessment of environmental performance of buildings
Clause 7–9 / Annex A. Defines the building-level calculation: the modular structure A1–A5, B1–B7, C1–C4 and D, the reference study period, the functional equivalent, and the rule that results from different assessments are only comparable when boundary, period and equivalent match.
The diagram below shows every direct connection this node has in the graph. Each line is one edge; expand a neighbour group below to read exactly why that connection exists and which standard or dataset it comes from.
This node has no recorded edges.
No neighbours to list.
How edges in this graph are derivedWI-GRAPH v1.0.0
Species → agent edges come from the WI-SL resistance profile (0–100 ordinal scale derived from EN 350 durability class, extractive chemistry and movement). ≥70 is read as "resists well", 45–69 as "moderately resists", below 45 as "is vulnerable to".
Climate → agent edges fire when a climate's driver value (UV, humidity, salt or freeze-thaw load) is 60 or above, read directly from the climate dataset.
Treatment → agent / standard edges come from the paraphrased standards corpus used across the site (EN 927-1, EN 351-1, EN 350 clause 4, EN 13501-1).
Species → standard edges reuse the exact source list already published for each Global WoodIntel Score sub-score.
