This thesis project was aimed at designing an energy efficient, intelligent and humancentriclighting solution for one of the steel manufacturing units of Sardogan Industryand Trade. The proposed lighting design will be used in order to reinforce a sustainable,digital and productive work environment in this family-owned business. To set thetechnical fundamentals for the new lighting proposal, the effects of industrial lighting onproductivity, well being and energy efficiency were researched. For future comparison, aversatile site analysis was performed to assess the existing working and lightingconditions of the space. This research was supported by an investigation of smartlighting fixtures and informal interviews with managers and workers from differentworkgroups. After reviewing the data gathered through research and analysis sections,an Industrial Internet of Things(IIoT) electric lighting system, 16 new skylights openings,and an experimental lighting control strategy was proposed. In addition to the increasein overall quality of lighting, advancements in the fields of energy sustainability anddigitalization could be observed. Also with the integration of a new lighting solution, adecrease in absenteeism and accidents was expected as well as an increase inproductivity and morale.

Store lighting is a combination of art form and function that contributes to a retail store's sales and prosperity. The quantity, quality, and effect of the light reaching the merchandise are the determining factors in the success of the sale of merchandise. There are three basic merchandise lighting techniques used in retail stores. They include the low-end, mid-market, and high-end lighting techniques. However, retailers are developing merchandising techniques that do not have a clear cut lighting solution. A new merchandising technique for the audio/video retailer is the simulated home environment (SHE). It is a series of rooms and vignettes that present audio/video products in a home setting. Studies have shown that lighting has an affect on human behavior. In a retail store, three customer behaviors are linked to increased sales: customer communication with store personnel; customer interaction with displays and merchandise; and length of time in the store. The purpose of this study was to determine which of the lighting techniques was most effective in stimulating the customer behaviors linked to increased sales in an audio/video store's SHE. The study was conducted in an audio/video store's SHE equipped with a lighting system that could produce the three lighting techniques. Each day the SHE's lighting system was set up for one of the lighting techniques and customer behavior was unobtrusively observed and recorded. A convenience method of sampling was used in the study. The subjects were the customers shopping in the SHE. The study's experiment was done twice using two methods for selecting the observation days for the experiments. One method used the same day of the week in three successive weeks (SDW), the other used three different days within the same week (DDW). The sample size for the SDW method was 123, and 47 for the DDW method. To assess the effectiveness of the lighting techniques in stimulating customer behavior, two behavior rating scales were created. The Customer Communication Rating Scale and the Customer Display and Merchandise Interaction Rating Scale assigned values to observed customer behavior. The third customer behavior, length of time in the SHE, was measured in minutes. Data was analyzed using Chi Square tests for the Customer Communication Rating Scale and the Customer Display and Merchandise Interaction Rating Scale. An ANOVA was used to analyze the length of time in the SHE. The results indicated that both the mid-market and high-end lighting techniques were significantly better than the low-end lighting technique in stimulating customer display and merchandise interaction, and longer customer visits in the SHE. However, the results indicated that all three lighting techniques were equally effective at stimulating customer communication with store personnel. The study concluded that store lighting designs that include highlighting of displays and merchandise will stimulate customer display and merchandise interaction and longer customer visits. / Master of Science

The fitting room is an important part of a clothing store, it's often where the customer decides if they want to buy the garment or not. Therefore it is important that the customer can feel safe and comfortable when they are trying the clothing. A typical fitting room in Sweden today has only one bright spotlight that emits light either towards the face or from the ceiling above. This study explores possible lighting solutions that take into account the customer's experience in the fitting room. The study aim to increase understanding of the importance of a good light in fitting rooms, so that customers gets a nice experience and that clothes, body shape and facial features are shown in a natural way. The issue therefore included how lighting can affect the customer's perception of the clothing and how the perception of body shape, facial features and the clothes change in different lighting solutions. To answer these questions, observations were made in various clothing stores, followed by an experimental study divided into two parts. The first part was a practical part where trying different lighting directions were tested on a mannequin, which resulted in three selected lighting solutions. The second part was a full-scale study. 15 people evaluated a fitting room with three different lighting solutions. The result demonstrates the importance of natural shadows and contrasts on the face and body and that it is important to consider how light falls and avoid glare. This is done by well-placed or shielded fixtures and by using several different lighting directions. The lighting in fitting rooms should be adapted to the type of clothes and customer group. / Provrummet är en viktig del i en klädbutik, det är ofta där kunden beslutar om plagget ska köpas eller inte. Det är därför viktigt att kunden kan känna sig trygg och bekväm vid klädprovningen. Ett typiskt provrum i Sverige idag har endast en ljuspunkt som belyser kunden antingen rakt framifrån eller ovanifrån. I denna studie undersöks tänkbara belysningslösningar som tar hänsyn till kundens upplevelse i provrummet. Studiens syfte var att öka förståelsen för hur viktigt det är med en god belysning i provrum, för att kunden ska få en bra upplevelse och att kläderna, kroppens form och anletsdrag ska framhävas på ett naturligt sätt. Frågeställningen innefattade därför hur belysningen kan påverka kundens upplevelse av klädprovningen och hur upplevelsen av kroppens form, anletsdrag och kläderna förändras i olika belysningslösningar. För att besvara dessa frågor gjordes observationer i olika klädbutiker, därefter genomfördes en experimentell studie som delades in i två delar. Första delen var en praktiskt prövande del där olika ljusriktningar testades på en skyltdocka. Denna resulterade i tre belysningslösningar att gå vidare med. Andra delen var en fullskalestudie där ett provrum byggdes upp med de tre olika belysningslösningar som sedan 15 stycken personer fick studera med hjälp av ett frågeformulär. Resultatet visar på vikten av att belysningen skapar naturliga skuggor och kontraster på kropp och ansikte, och att det är viktigt att tänka på hur ljuset faller, samt att belysningen inte är bländande. Detta görs genom välplacerade eller avskärmade armaturer och med flera olika ljusriktningar. Studien visar att belysningen i provrum bör anpassas efter typ av kläder och kundgrupp.

A pesquisa faz um levantamento dos sistemas de iluminação urbana e de fachadas atualmente instalados ao longo dos calçadões do Centro histórico de São Paulo, também chamado de Triângulo, qualificando-os segundo suas influências no modo como o pedestre entende o entorno e reconhece seus elementos, assim como o seu potencial convidativo em relação à utilização do espaço. A partir destes dados e discutindo o potencial que a luz possui para redefinir as referências espaciais na paisagem da cidade e influenciar o modo como o observador entende a arquitetura, o trabalho apresenta um conjunto de estratégias relacionadas a um plano diretor de iluminação urbana para o Triângulo, capaz de promover a melhoria do espaço urbano no período noturno e auxiliar o resgate da memória paulistana, explorando o uso do local e valorizando seus monumentos arquitetônicos. / This paper analyses the urban lighting system in addition to façade and street lighting installed on the streets of the historic downtown São Paulo, area also known as Triangle. It also verifies the lighting elements, considering the environment as well as its inviting potential in relation to its use. Based on the aspects of how lighting can improve overall appearance of a city or region, how it can redefine references of its landscape and influence the way a pedestrian perceives his/her surroundings some strategies of an urban lighting master plan will be shown as a way to improve the public space of the Triangle at night and preserve its historical landmarks driving more people to the premises and emphasizing its heritage.
