The emergence of corporations dabbling in sustainable development has caused a shift from the conventional way of managing office building to a more systematic approach involving high technology. Various discussions espouse the positive impact of sustainable office buildings on business. However, previous studies only discussed the elements involved, but most of these discussions did not specify which element that significantly contributed to business objectives. Thus, this research attempts to discover the relationship between corporate real estate sustainable management (CRESM) and corporate sustainability (CS) objectives to determine the most significant element of CRESM influencing overall CS objectives. A questionnaire survey was carried out involving 117 combinations of corporate real estate managers who are directly involved in managing sustainable offices in Malaysia. Data was then analyzed using IBM SPSS Smart PLS. Results indicate six elements of CRESM significantly affect CS objectives that hope to assist corporate real estate managers to well manage their sustainable office buildings as well as contributing to achieve their business objectives.
