# Business Models, Contracts, and Performance

Product-as-a-service, façade leases, deconstruction contracts, performance-based agreements, and the warranty/liability and asset-ownership consequences.

- [Light-as-a-Service](light-service.md) — contract for delivered lumens while the provider retains fixture ownership and recovery duties.
- [Façade-as-a-Service](facade-service.md) — contract for envelope performance while ownership, maintenance, and recovery obligations stay with the provider.
- [Deconstruction Contract](deconstruction-contract.md) — pay for careful dismantling, documented recovery, quality grading, and resale or reuse routing instead of only fast clearance.
- [Manufacturer Take-Back Scheme for Building Products](manufacturer-take-back.md) — bind the original supplier to take its product back at strip-out for reuse, remanufacture, or closed-loop recycling instead of waste.
