Advocates of sustainable energy had made several attempts to educate the professionals and ordinary people towards the energy development, efficiency, consumption and conservations for future energy sustainability. The aim of this study, is the exploration of Architect perception on energy –efficient design decisions for Ghanaian building industry. The study employed quantitative survey approach. Questionnaire was the main data collection tool. The questionnaires were distributed to a randomly selected sample of one hundred and thirty-five (135) registered architects out of the total population of 162 with Architects Registration Council of Ghana. The data was analysed using descriptive and inferential statistics such as factor analysis, and Pearson product moment correlation coefficient. The study revealed that the energy efficient design decisions made by the Architect on building envelope/orientation and site condition are passive solar technique, provision of natural ventilation, day lighting technique, and temperature of the building site and site shading strategy decision respectively. The findings of the study shows that, energy efficient design decisions performance is to reduced energy consumption, less energy cost and improves the comfort of occupants. The study recommend government to enforce the EED framework designs as an appropriate strategy to improve the energy performance of public buildings.
