Greening of any curriculum through the infusion of green skills is needed in the construction sector. This study identified important green skill areas in relation to building energy efficiency that are suitable for inclusion in the Building Construction Programme (BCP) at universities for the attainment of environmental sustainability. A questionnaire was used with 308 respondents. Data analyses were carried out using Descriptive Statistics, Exploratory Factor Analysis (EFA), and Confirmatory Factor Analysis (CFA). The supremacy of the identified energy efficiency skills over the non-energy efficiency skills is confirmed as its integration into BCP helps in realising environmental sustainability. Findings include the important areas to be included into the building construction programme curriculum. Findings can be used by the government for the adoption and practical implementation of these findings.
