Appendix B: Sample tracking spreadsheets

The tracking spreadsheet in Table B1, developed by Arup, enables teams to track the elimination of specific chemicals of concern from specific product categories over the course of a project. Within each product category, the available options are tracked and evaluated against several criteria: • chemical contents • volume of product used on the project • locations where products are installed • qualitative level of occupant exposure Users are able to weigh these considerations differently from project to project, or within different spaces in the project, to reflect project-specific values and priorities. Criteria can be added, removed, or weighted differently as project values vary. • This tool was developed for a mixed-use housing project at a major university, which used the following weightings: • occupant exposure (qualitatively evaluated) • percentage of construction cost • prevalence of the product or material in the building

Flexible weightings The tracking tool links products to the spaces in which they are used and to qualitative estimates of their prevalence within the building, their percentage of the project cost, and the potential that occupants are exposed to them. Weighting factors can be applied to each of these aspects to align with the project goals.

Comparing alternatives The tool can track and compare different product options for the same product category.

In addition to tracking this information and evaluating criteria within product categories, the tool provides graphical outputs, which provide easily interpreted feedback to the project team. The final output includes charts that show total reduction of specific hazardous chemicals compared to an assumption that all products commonly containing the substances have them. Various graphs display output organized by chemical, space type, and for the project overall, and separated by interior and exterior exposures. The tracking spreadsheet produces a series of graphs like the one below in Figure B2, which collectively compare the prevalence of chemicals of concern in different spaces.

Percentage tracking The tool recognizes that total elimination of chemicals of concern is not possible on all projects. It tracks the percentage of products used wtihin a space that still contain chemicals of concern.

Space-specific tracking Acknowledging that some spaces in projects might have different priorities than others, the tool allows users to track chemicals of concern on a space-by-space basis.
