Figure 1.
Structural equation model diagram shows relationships between policy-related factors and energy efficiency in retrofitting. Three main constructs appear on the left being enabling policies, specification of raw materials, and guidance to stakeholders involved in energy efficiency of buildings. Enabling policies connects to use of solar energy in E R, climate change policy is essential in E R, energy policy is essential in E R, and E R is cost-saving, with numerical values shown along each connection. The specification of raw materials connects to biofuel policy is essential in E R, the national energy policy 2020 is essential in E R, and recycled material is used in E R, each with associated numerical values. Guidance to stakeholders involved in energy efficiency of buildings, connects to contractors are a barrier to E R and designers are a barrier to E R, with numerical values shown on the connecting arrows. Curved arrows between the three main constructs show relationships among enabling policies, specification of raw materials, and guidance to stakeholders, each labelled with numerical values. Small circular markers appear beside outcome statements, each labelled with e numbers and numerical values, indicating measurement components within the model.Structural equation model to highlight key policies influencing energy efficiency in Zimbabwe’s retrofitting buildings
