The world of Fit-Outs is filled with industry-specific jargon that can be tricky when conducting LCA studies. Within Australia and New Zealand, the following are the typical delivery options of Fit-Outs used by building owners/developers: Integrated Fitout, Warm Shell, Cold Shell. In this article, we demystify these terms to help you understand the Fit-out scope of a project and provided some guidance on how to model the impacts and benefits of Fit-Outs in eTool.
What are Integrated, Cold Shell and Warm Shell Fit-Outs?
According to GBCA, Cold Shell, Warm Shell and Integrated Fit-Outs are defined as follow:
- Cold Shell: Finishes and services are not installed. A tenancy with an unfinished interior, with no HVAC services beyond the riser (or core or rigid duct), and without lighting, plumbing, ceilings, floor finishes (or with a setdown to allow for future provision of floor finishes), interior partitions or walls.
- Warm Shell: Finishes and services are applied to common areas. Tenancies are delivered with ceilings, floor coverings and lighting systems; and ducts from air supply and return risers, electrical and hydraulic services are installed above the ceiling from the riser throughout the tenancy areas.
- Integrated Fitout: Where the tenancy design and construction is fully coordinated with the base building. This includes finishes, services and fitout to all areas, common and tenancy, with services fully installed at each floor.
End-Life-Impacts for Fit-Outs
According to EN 15978 scope, the end-of-life impacts of the existing or previous building should not be included in the new building’s LCA. However, for interior fit-outs the situation is more complicated and depends on the starting condition. Several potential scenarios and guidance on how to attack these are below:
