EXPLORING USERS' PERCEPTION ON THE STATE OF APPLICATION OF INTELLIGENT BUILDING SYSTEM [IBSS] AND NON-INTELLIGENT BUILDING SYSTEM [NIBS] COMPONENTS

Purpose: The concept of automation has brought innovation in the construction and maintenance of buildings, leading to the evolution of the Intelligent building concept. The aim of research work is to investigate the components of intelligent and non-intelligent systems with a view to improving their functionality. Design/Methodology/Approach: The sample included respondents from intelligent and non-intelligent building occupiers, including buildings with intelligent components and non-intelligent buildings, drawn from the population frame of 10 buildings. A sample size of eighty (80) comprising intelligent and non-intelligent building users of the ten buildings was used. The results are presented in tables and figures. Statistical tools were used to process the variables, including the Relative Importance Index, Simple percentages, Spearman's Rank, the Mann-Whitney U test, the Student T-Test, and the Chi-square test. The study also explores relevant hypotheses to further confirm the discovery. Findings: The study discovered that application of intelligent component accessories in home has gradually gained ground in Nigeria, with application of features which includes the following: Automatic Fire Alarm Control E-System and Controls; Intelligent Perimeter Security Controls System; Air movement Purification System, General Access Monitoring System; Intelligent water purification and distribution; Intelligent HVAC System; Intelligent Perimeter Lighting control Systems; Occupants Energy Management system; Automated Parking Access and control system. Research Limitation: Data sampling was limited to Abuja and Lagos, which are centres of buildings with intelligent components, compared to other locations in the country. Practical Implication: The study recommends adopting concurrent innovation management styles, establishing strategic operational management, and timely management of the internal and external accessory environment to prolong component durability. Social Implication: The high cost of intelligent buildings makes them an exclusive preserve for the wealthy, while digital literacy among users is another challenge. A significant amount of wealth distribution is required for effective automation in Buildings. Originality/Value: The study identified new components that can be easily integrated into buildings to achieve building intelligence. It includes the following: Air movement Purification System, Intelligent water purification and distribution and Occupants Energy Management system.
