DES 308 Lighting Design Instructor: Julie Peterson Due: Friday, September 16, 2016 Reading Notes Red = overview with Julie WEEK 2 The Effects of Lighting on Consumers’ Emotions and Behavioral Intentions in a Retail Environment: A Cross-Cultural Comparison (#3) - Lighting affects emotional responses that influence consumers shopping behavior o Approach, avoid, time in store, purchases, and patronage - Pleasantness of in-store atmospherics was a significant predictor of consumers desire to approach or remain in the store and or to spend money o Lighting is one of major contributing factors for store atmospherics 3 major goals of retail environment 1. To attract the customer 2. To allow for evaluation of the merchandise 3. To facilitate completion of the sale o Color rendition and color appearance of light are important factors (Lighting design in retail store environments) Color rendition, cost, and lamp life are important factors when selecting a retail store lighting system RESULTS - Americans found the overall lighting in a room more affective then Koreans o As a whole they both found that color temp of 5000 K as more effective than color temp of 3000 K GROUP ARTICLE REVIEW #1 Design Issues – lighting effect the production of factory workers Demographics- 119 participant average age of 35 mainly women (Who ever on the shift schedule was a participant in this excitement) Testing area- factory, no daylight – they covered the windows, turned off every third light, measured in the summer from May to June and in winter January to March Findings– they didn’t feel that the lighting changes effected them but would like to have adjustable lighting, 1200 lux caused the fastest production (winter) and 800 lux the slowest. Application- controls and finding more horizontal lighting rather than vertical?? #2 jess The Impact of Light and Color on Psychological Mood: a study of indoor work environments • The aim of the study was to determine whether indoor lighting and color would have any systematic impact on the mood of people working indoors. • The study was carried out in real work environments at different seasons in countries with different latitudes. • Countries situated far north of the equator had a significant variation in psychological mood over the year that did not occur in countries closer to the equator. • The use of good color design contributes to a more positive mood. • The relationship between mood and the distance to the nearest window is bimodal. • Differences in the indoor lighting environment (levels, spectral distribution , temporal patterns, etc.) do seem to affect people in various ways. • Visual performance and decision making skills are affected by the visual environment and compete for mental processing capacity. • The mood shift for women was strongly negative for bight illumination conditions. • Depending on the latitude, season, weather conditions, and distance to windows, the workers might respond differently to indoor lighting. • The study was carried out over a period of time to get the best results and get a wider range of results as well. • 2% of all participants experienced the lighting conditions at their workplace as much too dark. • 15% considered a little too dark • 74% considered it just right • 9% considered it too bright • Large seasonal differences played a role too between countries and participants. • Apart from minor differences, male and females responded in a similar way and so did the younger and older personnel. • Mood swings may be partly related to the amount of daylight through windows. • May also reflect more basic seasonal variations of sub-SAD. • Arousal declined more than the other emotional qualities when the days were at their shortest. • The psychological mood was at its lowest when the lighting was experiences as much too dark. • The color of the workplace stands out as rather important. • Emotional status was higher throughout the year for those who had the most colorful work environment. (the brighter the color the better the mood) • and get a wider range of results as well. • 2% of all participants experienced the lighting conditions at their workplace as much too dark. • 15% considered a little too dark • 74% considered it just right • 9% considered it too bright • Large seasonal differences played a role too between countries and participants. • Apart from minor differences, male and females responded in a similar way and so did the younger and older personnel. • Mood swings may be partly related to the amount of daylight through windows. • May also reflect more basic seasonal variations of sub-SAD. • Arousal declined more than the other emotional qualities when the days were at their shortest. • The psychological mood was at its lowest when the lighting was experiences as much too dark. • The color of the workplace stands out as rather important. • Emotional status was higher throughout the year for those who had the most colorful work environment. (the brighter the color the better the mood) • Human emotions are influenced by a number of factors and only part of them might be related to the conditions in a workplace. • The impact of light and color is large enough to warrant increased attention. 9/16/16 1) What are the design issues? (overall goal, premise/argument) • To study whether indoor lighting and color would have an impact on workers moods. 2) What the steps they took? (research methods) (how many participants were involved? How were they selected? Demographic? Testing area?) • 468 female • 520 males • Ages 18 to 65 • Carried out in real work environments, schools, and industrial buildings • 4 different countries: Saudi Arabia, UK, Sweden, Argentina • Carried it out during winter and summer over two years • Lower number of hours in the winter vs. higher number of hours in sum mer 3) Key findings? • Whether male or female or younger or older, they all responded in similar ways • The mood was at its lowest when the lighting was “much too dark” • Women had a more negative response to bright light when males weren’t that affected or not affected at all. • Emotional moral was better when the work environment had brighter colors • When the days were the shortest, sadness and tiredness increased. 4) Practical applications? • Putting blinds on windows as an option for workers stations • Light dimming options • Better transitions between places containing bright lighting • Implement skylights #3 Design Issues – consumer’sreaction to the atmosphere of a retail store caused by lighting - Color temperature, and color rendering Research Methods– 98, 49 AmericanCaucasian ( 22 Males 27 females) Koreans 49 ( 25 Males and 24 Females) Age group 19-35, Those with lighting experience were excluded, From a student body and staff from multiple universities in south west U.S.. Koreans couldn’t be living in US longer than 3 years. Screened for color vision deficiencies and color vision test and for the presence f tinted or colored contact lenses - Two experimental cubical – Divided into 2 so 4 testing areas. Had windows with light blocking and filtering shades - 9am to 4pm late spring testing time 200Lux all time Key finding of study- Koreans preferred the cooling color temps and Americans preferred Warm Practical application for you –knowing who you’re designing (demographics) for and what they prefer in lighting #4 ANNA • Lighting has a big effect on self-appearance, and retail sales • Lighting can increase human interaction with a product • Frontal and overhear lighting are important for a flattering image • Spaciousness, privacy, visual clarity, preference andrelaxation levels all affect the way a person relates to a space • Good dressing room lighting should accentuate personal appearance, and facial molding • Peripheral Lighting with high contrast effects the feeling of privacy, and bright lighting makes a room feel spacious • Experiment o Gathered participants o The field experiment was conducted at a local area boutique store that carries upscale men and women’s clothing. However, the majority of the store is dedicated to women’s apparel. The store is located three blocks from a large university campus in the southeastern United States. The store is about 822 square feet (18 10 by 43 8), with a height of 14 1. The dressing rooms are located in the back of the store. Out of three dressing rooms, the front two dressing rooms were used for this field experiment because they are identical in size, shape, and surface finish (see Figure 1). The walls and ceiling are flat white painted drywall, and the floor is finished with light gray concrete paint. At the floor plane, they are approximately 4 1 by 7 4 with 7 8 high ceilings. Each room contains a chair, a hook, and a wallmounted mirror slanted backward by five degrees with a straight side and one angled side to match the slant of the wall (see Figure 2) o Two lighting directions were assessed in both dressing rooms: overhead (see Figure 3) and frontal (see Figure 4). Each experimental dressing room has overhead lighting from track-mounted incandescent lamps (two PAR20) mounted on the ceiling. Frontal lighting was achieved using 4 fluorescent sidelights (GE Lighting F32T8/SPX30/ECO) mounted in Lithonia standard strip light fixtures located at each side of the mirror. The lighting in this dressing room study met IESNA recommendations for a minimum 80 CRI and 3000K light source (Rea, 2000). The light sources were unshielded to minimize the effect of preference for a certain light fixture type. Because both sources were visible, bias was limited against preference for visible or hidden light sources. Figure 2. Dressing room section. The IESNA recommends 323 lux (30 FC) for overhead lighting in dressing rooms and 54 lux (5 FC) for frontal lighting (Rea, 2000). Lighting levels were kept even in this study to compare the differences resulting from lighting direction alone. The lighting levels were about 350 lux (35 FC) as measured on the floor 18 from the center of the mirror. o Arousal and Pleasure: no real difference o Self-evaluation on facial and body appearance: not much of a difference, but they noted less facial shadows on the frontal lighting o Dressing room evaluation: not much ofa difference, but the frontal lit room felt more roomy to them o In general, the frontal lighting was well received, except some said it was too bright • They discovered that arousal and pleasure and emotional state are more important in the retail area, and in the dressing room, people are more focused on how the clothes are working. • There is no statistical difference in lighting direction affects in dressing rooms • Design Issues: Studying Dressing room lighting to see if it affects how people feel about the clothes they are trying on • Research Methods: 60 females 18 to 35 filled out a survey in a dressing room, randomly selected, assigned a dressing room • Findings: Frontal Lighting ended up being the better option • Application: Can be applied to bathroom lighting, or in any area where people are paying attention to how they look Photo Biology– area of study - Section of science that deals with lighting and any living organism o How light and living organisms are studied - Like light therapy 100 lux = 10 foot candles
