The Athena Institute and other entities are working on producing performance benchmarks for use in whole-building LCA . An absolutely key part of this work is to define a standardized method for naming/classifying building products. Our initiative is set to assign products MasterFormat and UniFormat titles to arrive at a building-level “bill of materials”. A sample set of bill of materials will then be queried from a database and evaluated using LCA methods to arrive at a performance benchmark (e.g., kg CO2 per m2 GFA). Ideally, different benchmarking programs would use the same product naming convention for ease of data sharing.
OmniClass Table 23 (“Products”) is helpful but we need to incorporate other identifiers such as thickness (e.g., 1/2" vs. 5/8" gypsum board), strength class (e.g., 300 vs. 400 MPa rebar), and unit of measure (m2 vs. m3 vs. tons). I found one method, the “Open BIMObject Standard” from Australia (http://www.iibh.org/pdf/icis/OBOS(The%20Open%20BIM%20Object%20standard)_V1.0_2018.pdf). Is there a more internationally recognized/used standard than this?
If someone has produced a product list according to a standardized method that would be extremely useful to see. Any other comments are very much welcome, this is a tricky topic and it would be great if we could converge on some sort of consensus.
