Abstract

The study aims to suggest sampling structures to avoid sacrificial pseudoreplication in the evaluation of Leadership in Energy and Environmental Design (LEED)-certified projects. The sampling includes two structures that exclude sacrificial pseudoreplication and one structure that leads to sacrificial pseudoreplication: (i) The state is the sampling frame in which LEED projects are treated as primary sampling units; (ii) The US is the sampling frame, the state is the primary sampling unit in which LEED projects are treated as evaluation units; and (iii) The US is the sampling frame in which LEED projects are pooled from different states and treated as primary sampling units. The three sampling structures are applied to the evaluation of the Silver-to-Gold cross-certification performances of LEEDv3 for new construction and LEEDv3 for existing buildings. The same cross-certification strategy was revealed if either structure (i) or structure (ii) was applied, while it was poorly estimated and misinterpreted if structure (iii) was applied, i.e., sacrificial pseudoreplication had occurred.
