Since a full-fledged study of the properties of experimental samples of mercury lamps is impossible without a reliable method of photometric measurements, and for ozone lamps such a technique, taking into account the features of the object of study, has not yet been proposed, its development and testing is the main task of this work. Based on the analysis of existing techniques, a technique for measuring the fluxes of the 185 and 254 nm lines of a low-pressure mercury lamp is proposed, taking into account the change in the nature of the spatial distribution of radiation during operation, without directly measuring the RIC. The method proposed by the author for measuring the fluxes of ozonizing and bactericidal radiation can be used as the basis for the development of an automated system for measuring parameters and monitoring the quality of gas-discharge UV radiation sources.","PeriodicalId":363368,"journal":{"name":"Proceedings of the Conference CIE 2021","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130273686","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Integrating daylight with electrical lighting can serve as a means to lessen electricity costs for buildings. Geographic location and weather conditions facilitate most of the areas of Nepal to receive on average 12 hours of daylight and have huge energy-saving potential. However, the integration of daylight has not been admitted in the building code of Nepal. Moreover, contemporary architectural design lacks employment of techniques illustrated by illumination engineering to integrate daylight. This study analyses the plausibility and benefits of integrating daylight with electric light for a typical commercial building of Nepal employing the DIALux model and simulation. Simulation integrating energy-efficient electric light and daylight was done to observe illumination levels and light power density. For daylight performance, year-round conditions were observed for three different sky types. Modification of building architecture to integrate daylighting components was also studied. In the later part of the study, analysis was done to observe energy-saving potential and financial benefits. Results designated the plausibility of blending daylight with electrical lighting in the building for all-sky conditions. Extensive energy thrift was observed and was higher with added daylight components. Recommendations of the study to blend light sources and incorporation of daylight components are attainable with current technology and trend in Nepal with accompanying benefits of energy-saving, reduced operation, and reduced maintenance cost.","PeriodicalId":363368,"journal":{"name":"Proceedings of the Conference CIE 2021","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130713563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These sites are recognised globally and are of immense importance to the local and worldwide audience. The majority were constructed during the 15th to 18th century and were designed to incorporate oil or fat-based wick lamps for lighting. The intervention of modern electric lighting in these structures should be carried out without conceding cultural values, visual perception, and traditional outlook. However, in most sites, there are no lighting or unscientific lighting interventions which are inappropriate, unsurpassed, exaggerated, and unpleasant. The light source spectrum is an essential factor in enhancing the natural appearance, increasing luminance, reducing degradation of artefacts by photochemical action, and reducing power consumption. The study aims to characterise the white light spectrum for its appropriateness to enhance the optical parameters by observing the spectral reflectance of the building materials of these sites. The experiment uses RGB tunes LED light source to obtain white light of different SPD and CCT. Building materials from Bhaktapur Durbar Square and Tripureshwor Mahadev temple and light SPD with CCT in the range of 1735 to 7669 K were used for the study. The study thus makes recommendations for an appropriate spectrum of light sources for Nepal’s heritage sites and monuments based on the experimental findings.","PeriodicalId":363368,"journal":{"name":"Proceedings of the Conference CIE 2021","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132305940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite evidence demonstrating the critical role of the hospital’s luminous environment in responding to occupants’ requirements and needs, and the importance of engaging with the patient experience to improve the quality of patient care, to date, no studies have articulated approaches to study conflicting occupants’ needs for lighting in context. This paper presents a semi-systematic literature review of disciplinary approaches to investigate quality lighting conditions in hospitals and subjective impressions of occupants. Research articles from the clinical, built environment, and lighting fields were selected and evaluated. The review outlined appropriate physical (i.e., photometric) and self-report (e.g., preferences) approaches for data collection in context and potential articulations between them. Mixed data collection and data analysis techniques are deemed essential to articulate lighting design strategies engaging with the requirements of hospital occupants on a 24-hour basis.","PeriodicalId":363368,"journal":{"name":"Proceedings of the Conference CIE 2021","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124336763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
