Smart Lighting Application for Energy Saving and User Well-Being in the Residential EnvironmentBog'liq modellashtirish Photoshop rastrli grafik muharririda ishlash asoslari, 1 saida opaga2. Materials and Methods
A literature review was conducted using two scientific literature databases: Scopus
and Web of Science. Both databases are known for multidisciplinary peer-reviewed sci-
entific literature and cover subject areas within the field of social, physical, health, and
life science. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses
(PRISMA) statement [
33
,
34
] was used for finding, reporting, and evaluating records. A
PRISMA flow diagram was used to show the flow of information in the different stages of
the review process, indicating the number of identified records, included and excluded, as
well as the reasons for exclusion.
2.1. Eligibility Criteria
The eligibility criteria were based on the publication year (2001 onwards), subject
area, document type (limited to peer-reviewed journal articles and reviews), and language
(English). The publication year was set to studies published after 2001, as this was the
year in which information about the additional functionality of photoreceptors in humans,
largely responsible for light effects beyond vision, was published (e.g., [

–

]). Specific
subject areas were excluded, as they resulted in finding irrelevant papers (material, econ-
omy, agriculture, earth/planetary, arts, pharmacology, chemistry, chemical engineering,
bionic, immunology, business).
2.2. Search Strategy
The search process started by defining and categorising search terms, which were
divided into four categories (see Table
1
). The category ‘Lighting system’ was the main
interest of this study and included all terms related to smart lighting. The synonyms for the
term within this category were expanded numerous times during the search process. The
category ‘Context’ provided the focus on residential environments. The category focusing
on the outcomes of the studies, ‘Light effects’, was divided into ‘Light effect on energy’
and ‘Light effect on well-being’. The latter two categories resulted in two search strings: (1)
‘Lighting system’ and ‘Context’ and ‘Effects on energy’ (2) ‘Lighting system’ and ‘Context’
and ‘Effects on well-being’.
2.3. Study Selection
The search strings were applied within both databases, the results were merged, and
duplicates were removed. Subsequently, three reviewers (the authors of the paper) screened
the papers on title/keyword/abstract (TKA) individually by checking the relevance of the
studies regarding smart lighting in a residential context on either well-being and/or energy.
Papers were selected for a full paper review if two out of three reviewers assessed the
paper as relevant. During the TKA screening process, papers were included in case they
investigated the impact of a smart lighting system on energy and/or user well-being in a
residential environment. Consequently, papers were excluded when they were conducted
or proposed for a non-residential environment, were review papers, designed conceptual
frameworks without reporting energy or well-being related issues, used non-smart systems,
developed algorithms exclusively, focussed on user interaction with smart home appliances,

focussed on user behaviour exclusively, or were conducted with a very specific user group
(e.g., patients suffering from severe dementia). In case the results were technical papers
or if the full paper was not available, the article was not included in the full-paper review.
Additionally, the references of the found papers were screened to find more relevant
studies.
