Abstract
Purpose
Interior workspace environments use exclusively artificial light, resulting in a loss of biological connection and natural light quality, as well as greater energy consumption. The purpose of the study is to identify a suitable system that can provide natural light to such interior spaces throughout the day while supplementing it with artificial light when necessary. The fundamental aim is to provide insights into the most effective solutions for energy-efficient lighting design in the UAE's environment, with the potential to lower energy consumption related to interior lighting.
Design/methodology/approach
The study adopted an empirical approach to gather and analyze primary data based on field measurements to understand and assess existing lighting conditions, as well as DIALux lighting simulation software to test the efficacy of the proposed HLS in terms of natural light delivery, illumination quality and energy consumption. A branch of a local bank in the United Arab Emirates, situated inside one of the shopping malls where there is no natural light penetration, has been chosen as a case study.
Findings
The findings of comparing the base case to four probable scenarios that used HLS revealed that the third scenario, which uses 100% pure sunshine and 35% artificial LED light during daylight operations and 100% LED light during night duty, is considered to be optimal in terms of illumination quality and energy efficiency.
Originality/value
The study demonstrated the potential of innovative lighting to improve the visual working environment in interior spaces with limited access to direct natural lighting, especially in arid regions, where sunlight is plentiful throughout the year. The study contributes new insights into the establishment of lighting-related recommendations and standards for the UAE context. This may include advice for sustainable construction practices, lighting guidelines or incentives to encourage the use of hybrid lighting technology in commercial and institutional buildings.

Abstract
Purpose
Night lighting reflects the prosperous development of economic and the increasingly rich and colorful cultural life. Currently, various technical standards, protocols and management specifications have been developed to build a safe, comfortable and economical lighting environment. However, prevailing evaluation systems focus on objective indexes of illumination and have ignored environmental characteristics and subjective feelings and lacked consideration of regional culture, economic benefit, management and maintenance. In this context, a lighting evaluation system combining subjective and objective is proposed for the first time in this study to explore approaches to guide the development of a healthy and comfortable urban night-time environment.
Design/methodology/approach
Existing research and relevant lighting standards are analyzed and an evaluation model with a logical hierarchy is constructed by combining with the evaluation theory that is set based on people and the environment. The index weights were scientifically determined on the basis of the analytic hierarchy process (AHP) and fuzzy comprehensive evaluation method. The rationality and validity of the proposed evaluation system is verified in accordance with field projects and case studies.
Findings
Taking into account traditional and cultural factors, the evaluation model established has an acceptable accuracy. Evaluation based on subjective-objective combination can provide a scientific basis for the management and optimization of night lighting.
Originality/value
The proposed evaluation system can serve as a guiding reference for other areas of cultural identity and esthetic perspective.

Abstract
Purpose
The study aims to explore factors that influence students’ academic performance in the context of physical ergonomics and assess the mediating effect of motivation between lighting, noise, temperature, chair design and students’ performance from the student’s perspective.
Design/methodology/approach
The research was categorised as a correlational study and employed non-contrived and cross-sectional methods to achieve its objectives. The target population was university students aged 18 years old and above enrolled in Malaysia’s higher education institutions. Due to the inaccessibility of the sample frame, convenience sampling, a type of non-probability sampling, was utilised. Data collection was conducted through an online survey primarily distributed among student groups.
Findings
The study’s findings reveal that only two exogenous variables, lighting and noise, directly influence students' performance. Additionally, motivation is a potent and significant factor in shaping students' performance. Motivation is also identified as a mediator in the complex relationship between lighting, noise, temperature and student performance. Surprisingly, although temperature does not directly influence student performance, it indirectly influences performance through motivation.
Originality/value
This study is an original exploration into the intricate factors shaping students' academic performance within the domain of physical ergonomics from a student perspective. The research uniquely investigates the mediating impact of motivation on the relationships between lighting, noise, temperature, seating arrangements and academic outcomes. The findings will contribute novel insights to the existing body of knowledge, offering a distinct perspective on the complex dynamics that influence student learning experiences and performance in educational settings.

Abstract
Purpose
This study aims to answer the question of how incumbent firms cultivate dynamic capabilities through knowledge management so that they can efficiently adapt to the changing external environment.
Design/methodology/approach
This study adopts a case study approach and collects data through interviews and secondary public information on the lighting industry and two lighting firms in Lin'an, China. It qualitatively examines the challenges and strategic recommendations for incumbent firms in the context of discontinuous technological change from a knowledge management perspective.
Findings
Incumbent firms often face a variety of challenges when responding to discontinuous technological change. These challenges include identifying opportunities, overcoming path dependence and dealing with employee resistance to change. To overcome these difficulties, three strategies have been proposed to enhance the dynamic capabilities of incumbent firms through knowledge management: cross-border search helps firms improve their knowledge acquisition capabilities and better understand their environment to identify opportunities; building strategic leadership overcomes path dependence and improves knowledge integration capabilities; organizational learning deepens employees’ understanding of change and enhances organizational knowledge application capabilities.
Research limitations/implications
Previous research attributes a firm's ability to cope with discontinuous technological change solely to its general resources, which weakens the importance of knowledge management in this context. This study emphasizes the importance of knowledge as a crucial strategic resource in developing the essential dynamic capabilities for incumbent firms to cope with discontinuous technological change.
Practical implications
This study provides an in-depth analysis of incumbent firms' coping strategies in the new context of discontinuous technological change and further promotes cross-disciplinary research.
Originality/value
This study provides an in-depth analysis of coping strategies in the new context of discontinuous technological change, furthermore theoretically advancing the interdisciplinary research of firm transformation and knowledge management. Meanwhile, it is crucial to identify the preconditions for cultivating dynamic capabilities, especially from a knowledge-based view, which enhances the depth of knowledge management research.

Abstract
Purpose
Design is an important construct in the retail environment literature. Yet, the measures used for design have not followed appropriate scale development procedures. The purpose of this study is to provide a conceptual definition and then develop a scale for retail environment design (RED).
Design/methodology/approach
Interviews with both consumers and marketing researchers are used to generate a potential list of items. Using four different studies, these items are refined, and the RED scale is offered.
Findings
This study develops and validates the four-dimensional RED scale to measure the design of retail environments. The dimensions are functional, aesthetic, lighting and signage.
Research limitations/implications
The newly developed RED scale will allow retailing researchers to measure lighting and signage qualities as part of retail design, measure design of retail environments more accurately and allow different studies to be compared.
Practical implications
The newly developed RED scale will allow retailers to better understand customers’ perceptions of the four dimensions of design. Retailers spend significant time and money designing and redesigning retail environments. The RED scale will enable managers to ensure these significant investments create competitive advantages and an appropriate return on investment.
Originality/value
A scale to measure retail environment design is developed. The scale includes two dimensions (lighting and signage) that are not typically investigated.

Abstract
Purpose
The most challenging aspect of hospital design is the creation of an environment that heals rather than the one acting as a barrier to healing. Much has not been done in the aspect of ascertaining the level of impact “indoor environmental quality (IEQ)” has on building occupants in healthcare facilities. Therefore, this study aims to investigate the impact of IEQ on patients' health and well-being.
Design/methodology/approach
The study investigates the hypothesis that four IEQ parameters (thermal quality, acoustic quality, lighting quality and indoor air quality [IAQ]) influence patients' overall satisfaction with the performance of hospital wards. Questionnaire responses were sought from the patients as the main occupants of hospital ward buildings. A proposed weighted structural model for IEQ establishing the relationship between IEQ parameters, patients' overall satisfaction and patients' health outcome was analyzed using structural equation modeling (SEM).
Findings
The most influential IEQ parameters on patients' overall satisfaction with IEQ in hospital wards are thermal quality, IAQ and lighting quality. The findings from this study revealed that the parameters of influence on patients' overall satisfaction and health outcomes vary with hospital ward orientation and design configuration.
Originality/value
This study has explored the need for the integration of all factors of IEQ at the building design stage towards providing a hospital environmental setting that reflects occupants' requirements and expectations and also promotes patient healing processes. This should be the focus of architects and healthcare managers and providers.

Abstract
Purpose
This study aims to characterize the experiences of health professionals participating in an exploratory randomized controlled trial designed to improve hearing and vision among older adults without dementia receiving the in-home health services provided by Norwegian municipalities.
Design/methodology/approach
Semistructured individual and paired interviews were conducted by nine health professionals from five municipalities to explore health professionals’ experiences with the intervention. The data were analyzed using content analysis.
Findings
Three main categories of experiences were identified: (1) participating in the intervention, (2) emerging new knowledge and (3) developing in-home health services. The mutual collaboration between health professionals and service recipients during the screening process led to a more-thorough understanding of the service recipients’ needs and resources, enabling personalized advice and guidance.
Research limitations/implications
In-home interventions have the potential to improve the quality of life of older adults with hearing and vision impairments. Given the promising outcomes of such interventions, future research should (1) investigate their effects on changes in behaviors and attitudes, (2) integrate technological advancements and (3) explore environmental modifications to further enhance the quality of life of older adults in various settings.
Practical implications
The health professionals in this study enjoyed assisting the service recipients in receiving in-home health services by screening their hearing, vision and indoor lighting conditions. The trial enabled the health professionals to provide personalized advice, and to motivate and guide the service recipients toward actions to remedy their impairments.
Social implications
The health professionals recommended hearing, vision and indoor lighting screening to be a routine municipal service because it would safeguard independence, prevent falling and maintain the quality of life of service recipients. However, additional resources are needed to implement these recommendations.
Originality/value
In-home interventions have the potential to improve the quality of life of older adults with hearing and vision impairments.

Abstract
Purpose
The amount of energy consumption of buildings has obtained international concern so the concept of zero energy building becomes a target for building designers. There are various definitions and evaluation methods for efficient buildings. However, detailed research about the critical parameters that have a major effect through the operational time to reduce the energy consumption is not emphasized as this paper represents. The main aim of this study is to identify the effect of applicable interventions on energy consumption parameters with their sensitivity to each other to reach zero energy building. Relatedly, the cost of energy reduction is also determined.
Design/methodology/approach
Energy consumption parameters were defined as area lightings, space heating, space cooling, ventilation fans, pumps, auxiliary equipment and related miscellaneous equipment. The effect of each applied intervention on energy consumption was classified as high, medium, low, very low, no effect and negative effect by utilizing a sensitivity analysis. The base case's energy model is created by utilizing energy performance software such as e-Quest. Accordingly, energy performance improvement scenarios are developed by applying interventions such as lamp replacements, sensors, heat pumps and photovoltaic panels’ integration. Furthermore, sensitivity analyses of each intervention were developed for consumed energy and its cost.
Findings
Results indicated the electric consumption is more effective than gas consumption on primary energy and energy cost. Solar systems decline primary energy by 78.53%, lighting systems by 13.47% and heat pump by 5.48% in this building; therefore, integrating mentioned strategies could rise the improvement rate to 100%, in other words, zero amount of energy is using from the grid that means saving $ 5,750.39 in one year.
Research limitations/implications
The study can be applied to similar buildings. It is worthwhile to investigate suggested methods in diverse buildings with different functions and climates in future works.
Practical implications
This study aims to investigate of energy consumption of an educational building in the Mediterranean climate to convert an existing building into a zero energy building by saving energy and renewable sources. Subsequent purposes are analyzing the effect of each strategy on energy consumption and cost.
Originality/value
The novelty of this study is filling gaps in sensitivity analysis of energy consumption parameters by not only identifying their effect on overall energy consumption but also identifying their effect on each other. Some interventions may have a positive effect on overall consumption while having a negative effect on each other. Identifying this critical effect in detail not only further improves the energy performance, but also may affect the decision-making of the interventions.
