A contract with an architect, designer, or developer in which they are paid a bit more than they conventionally would have been, but part of their fee is paid over time from the savings their solution creates in terms of either performance or efficiency. Conversely, designers and developers are often paid a percentage of the costs of the materials they specify, an incentive to be less efficient.
