Proposed circular value KPIs extracted from selected initiatives

Circular principles/ Value proposition	Circular value KPI
Circular principles/ Value proposition	Code	Description	Impact*	Unit
Narrowing the loop
Reducing used material or virgin resources in a product
	N1	Material per product	↓ Negative	kg/product
	N2	Virgin/non-bio-based resources per material (used material in a product)	↓ Negative	% of total material mass
Reducing fit-out products in an office unit
	N3	Product per function	↓ Negative	Number of products/function
	N4	Product per office unit	↓ Negative	Number of products/office unit
Reducing office units or office building
	N5	Office units per function	↓ Negative	Number of units/function
	N6	Office units per user	↓ Negative	Number of units/person
Slowing the loop
Increasing estimated life span of products
	S1	Durability: The life span of fit-out products through fit-out product's quality	↑ Positive	Years
	S2	Reuse/retain rate in the building: Number of cycles that a product is retained/reused in the same building	↑ Positive	cycles/product
	S3	reuse/retain rate in fit-out cycles: Retained/reused product in a refit- defit cycle per total fit-out products	↑ Positive	% of reused items/total fit-out items
	S4	Refit-defit cycles in buildings life span	↓ Negative	cycles/building life
Closing the loop
Increasing the recovery potential in an office building/unit
	C1	Recovery rate: reused or recycled material per removed material) in a strip out/demolition project	↑ Positive	% (recovered mass/total removed mass)
Increasing the potential of product's circulation at EoU or EoL
	C2	Product parts recyclability: Recyclable elements/parts of a product per all parts	↑ Positive	% (by count or mass)
	C3	Product parts reusability: Reusable elements/parts^* of a product per all parts	↑ Positive	% (by count or mass)

Note(s): *: ↑ Positive (higher better) ↓ Negative (lower better)

Ni: KPIs affecting the pre-use stage by Narrowing the loop Si: KPIs affecting the use stage by Slowing the loop

Ci: KPIs affecting the post-use stage by Closing the loop * Reusable parts of a product for remanufacturing, and repurposing
