Operators (owners/facility managers) of high-rise buildings are continuously faced with the challenge of finding innovative means of controlling and managing the facilities of high-rise buildings. This is due to consistent change in the nature and functions of building systems. Meanwhile, the use of computerized systems affords building operators the tools and methods that will enhance facility management activities. This study examined the importance of automation to the facility management of high-rise buildings in developing countries, using the case of Nigeria. The study adopted a survey research approach, administering a structured questionnaire to 53 facility managers of identified commercial high-rise buildings in Ikoyi, Lagos Island, and Victoria Island in Nigeria. It also applied regression analysis in determining the significance of automation on facility management activities. The findings of the study revealed that security services are the most automated facility management activity. Results also showed that automation had a positive effect on facility management practice, with R square of 0.66. The study concluded that although automation is seldom used in carrying out facility management activities, it has a positive impact on facility management services, with 66% significance level on facility management activities. It then recommended that steps should be taken by all stakeholders to develop the practice of facility management and research, as well as facility management education.
