Book an ERIWhat is an ERI?
An Extended Resources Inventory is an audit during the in-use phase of a building to verify value and guarantee correct maintenance and disassembly. It meets BREEAM In-Use RSC03 requirements and includes assessment of current financial value plus guidance on maintaining value during deconstruction. The inventory covers resources belonging to the asset owner, not tenant-owned fittings and furnishings.
Maintain value during disassembly
The ERI provides guidance on preserving the value of significant resources during disassembly and demolition. It includes strategies to minimise damage and practical guidance for resource retention. A full deconstruction plan is not required — the focus is on actionable guidance that protects asset value.
Maximise financial returns
The inventory identifies opportunities to maximise financial returns or minimise costs through reuse and recycling. It outlines potential markets and uses for materials, and considers evolving trends and technologies that may affect future value.
