This paper investigated and compared how the energy consumption of a conventional and Smart Lighting System (SLS) in a simulated residential setting is affected by different households’ arrangements and occupancy pattern. An agent-based simulation model of a one-bedroom apartment in Sweden was chosen for comparison with different scenarios. The result shows that the number of residents within an apartment does not necessarily lead to higher energy consumption. Further findings indicate that, even though it has standby energy consumption, SLS is more energy efficient compared to the conventional lighting system. Additionally, energy consumption during weekends was considerably higher than during weekdays.

The idea of smart lighting has emerged over the years in commercial and industrial environments, with a focus on energy saving. With the advancement in technology, smart lighting can now offer opportunities in addition to energy saving to users in home environments for the provision of a comfortable atmosphere and the maintenance of user well-being. Currently, research in the smart lighting field is predominantly dedicated to energy saving in non-residential environments; meanwhile, the residential environments have not been explored. Therefore, a literature review was conducted to provide an overview of smart lighting systems’ effect on energy and well-being in the residential environment. Current research is mostly limited to designing and developing a smart lighting system in a controlled environment, with a limited evaluation of well-being and comfort. The review shows that residential smart lighting application possibilities and opportunities are not widely and thoroughly explored.
