▼ Twist-Pair Towed Camera (abbr. TP-TowCam), which means when we use this vehicle in the ocean, the more depth we yearn to explore, the more darkness we have. Therefore, we demand the deep-sea lights to augment the illuminance of hydrography. There is one problem we need to face, inasmuch as the light in the ocean was absorbed and scattered by the seaâs depth. It makes a point that the TP-TowCam fails to take a photo in the depths of the ocean. However, consider that TP-TowCam influence the security of operation and the horizon of vision. We hope we can increase bulbs in the vehicle to extend the seafloor, yet we do not clear that the number of lamps we add is able to let vehicle, the distance between the vehicle and seabed is approximate 3 to 4 meters, raise the height of taking photographs. In order to discuss this issue, first of all, we are resolving the elemental character of optics. Second, utilizing decline of transmitting light this theory, considering what is the different illuminance value in various elevations below the ocean. Lastly, using the vehicle can receive the threshold of minimum (the minimum value is 0.2 lux) finding the maximum of altitude on the seafloor. The simulated results indicate that the number of the TP-TowCamâs light can ensure meet our target in lightly turbid ocean waters. On the other hand, in highly turbid ocean waters, we have no ability to assure the vehicle is work or not. The key point of the vehicle is involved in Para-boat and cable, but the vehicle has to manage its height. Thus, we need to control the cable and speed of ship to restrain the vehicle from specific altitude. Hence, this study is through the simulated process of cable in the static state to discuss the effect of tow height in diverse acceleration. To sum up, the ship in different accelerate influence of the vehicle in the size of fluid friction. Besides, the speeds of ship also affect the vehicle to tow in different altitude.

▼ This thesis concentrates on lighting preferencesin living rooms concerning Nordic lightqualities in winter. Living rooms are spaceswhere we relax, communicate, eat, gather andread. Lighting in living rooms gives hints aboutour perception and character.Nordic countries, there is something uniquethan others; use of light and daylight sensiblyand wisely. In the Nordic countries, where thelight and darkness change dramatically betweenthe seasons, the transitions have a specialsignificance. Higher the latitude, twilight hoursare getting longer, and it creates a homogeneoustransition between daylight and night.The thesis consists of literature research andsurvey. Literature research concerning the topicbriefly explains different aspects of the color oflight, its effects on performance, basic lightingsolutions and Nordic daylight qualities in winter.Furthermore, the culture of window lightingand use of daylight as a background are studiedand added to the survey in order to understandthe relation between indoor and outdoor lightqualities from the participants’ perspective.The survey with twenty-one questions andseventy-two participants tries to evaluatehow Nordic light affects people’s preferences.Evaluation and results followed by thediscussion of desired color temperature, lightinglevel, comfortability under Nordic daylight inwinter. Additionally, paintings from differentseasons help me to understand awareness oflocal daylight and attention of participants.Results show us that the attention people giveto the desired light intensity and colors aremore related to the people’s interests than totheir background, profession and length ofstay in Stockholm. It would be interesting toinvestigate this topic with more people who livein Stockholm more than five years.The concentration of the thesis is understandinghow local daylight conditions can affect people’slighting preferences in their living room.Results will help us to implement the knowledgeand collected information into the lightingdesign process in living rooms in Nordic countries.

Artificial lights in our buildings have always been designed to be static for one purpose only; illumination. With the increasing interest in Visible Light Communication (VLC) and a crowded radio-frequency spectrum, static lights in our offices and rooms might not be ideal anymore. VLC can add extra services like high quality communication and localization. These services benefit from optimal circumstances as we can find in the hot spot below the lights. Outside the hot spot, the intensity of the lightbeam starts to drop rapidly. This research is dedicated to the aspect that the static lights are lacking which is mobility. Instead of having static lights we create a light source that is able to move along with persons in a room. In this work, which consists of the design and evaluation of our system, we create a mobile platform which includes enhancement of an existing gondola system, the design of a small mobile LED-transmitter and a smartphone as receiving device. We designed a system for the light to follow a user. The smartphone can locate the light and it calculates the location offset through image processing. New coordinates for the light are send to the gondola system to move the light and keep the transmitter and receiver in sync. The system was tested by installing it in the Embedded Systems laboratory of the TU Delft and evaluated in terms of illumination, communication and energy efficiency compared to a static light network. We can conclude that a mobile light can add extra services to VLC by ensuring a constant high illuminance and signal-to-noise ratio by using individual focused hot spots that follow the user in real-time, with an average position error of 1.74 cm, which the static light network can not do causing a performance degradation. The mobile light is in most cases also more energy efficient than a full hot spot static light network coverage. Besides that, we obtain a 3.91 centimeter precision indoor localization as an extra result.

▼ Work-related musculoskeletal disorders (WMSD), affecting tendons, bones, ligaments or vertebral discs, are very common today. Actually, companies opt for open spaces, these are spaces where there are no walls, doors, or workspaces for each employee, they simply bring them all together in the same area, with continuous desks and next to each other. This study is focused on an open office and aimed to identify and evaluate the main risk factors for musculoskeletal problems and visual stress. First, the place was visited to have a more specific idea of this, then a questionnaire based on the Nordic questionnaire was applied to 20 workers, to which other questions related to demographic data, lighting, visual stress, among others were added. In order to develop an ergonomic assessment, the Rapid Office Strain Assessment (ROSA) was applied, which is a method commonly used to evaluate jobs in offices. In addition, the lighting data were recorded in 35 desks/workplaces, according normative requirements. From the Nordic questionnaire, the body regions more affected by musculoskeletal pain/discomfort during the last 12 months were the feet (70% of the 20 workers), lumbar (65%), neck (55%) and knees (50%). Considering the ROSA assessment, the final value was 5 points, which indicates that exists a risk for high discomfort and possible occurrence of musculoskeletal disorders. Therefore, these results pointed out the need for further research and modifications to the workplaces. Relatively to the lighting, the illuminance values obtained are lower than the values recommended by the European Standard – ISO 8995: 2002, justifying the visual complaints reported by some of the workers. Summarily, this open space needs intervention at the level of lighting, since adequate lighting of the workplace contributes to the safety, well-being and comfort of the employees. At the same time, ergonomic measures (such as occupational gym and physical reorganization of the workplaces) were needed to decrease the musculoskeletal risk. In this domain, the ROSA method is a useful and easy method to assess WMSD risk in offices. Advisors/Committee Members: Colim, Ana S (advisor).

▼ Most shading device systems installed in windows or glass walls are used only for protection from overheating and glare, neglecting other possible functions, such as increasing the daylight level in the space or collecting solar energy. The blinds are usually made of opaque or translucent materials, and if they are partially open/closed or completely closed, a direct view to the outside is blocked. A balance between a sufficient amount of daylight and protection from overheating of the space in summer is not often achieved due to inappropriate control of the blinds’ tilt angle. There is also a need for specific guidance for the selection and design of shading device systems in the windows. This research develops a general decision-making framework (DMF) that can be used by architects and manufacturers of shading devices. The general DMF is a guide for the user in analyzing shading device performance in the process of selection/design of the shading device. This research also develops a specific DMF to better understand and validate the general DMF. The specific DMF, based on illuminance and luminance, is used for an analysis of daylighting performance of shading devices to select the best possible existing system or new system among several alternatives. Architects or manufacturers of shading devices, as the users of the DMF, analyze various systems of blinds applied on a particular building and at a given location. The users of the DMF can apply either an experimental procedure or computer simulation that provides information about illuminance and luminance levels in the space. Based on the analysis of the results of the experiments or simulations, the user of the DMF decides which blinds to select. The specific DMF proposes a methodology for both the analysis of the daylighting performance and for the process for making a decision based on the results of the analysis. A case study is conducted in order to validate the DMF. Three types of shading devices are tested: an existing system, a patented system, and a new system, proposed by this research. The shading devices are installed in an office space located in Roanoke, Virginia. The software Autodesk VIZ 4 is used to simulate daylighting performance. The output information, such as illuminance and luminance levels in the space, is used as a basis for making the decision about which type of blinds to apply. A new system of shading device, which has a triangular cross section and is made of clear plastic with a silver coating on one side, shows better performance than the existing shading device and the patented shading device, given the research limitations. By using the specific decision-making framework, a shading device manufacturer/designer is able to understand the shading device daylighting performance from his design-imposed criteria. Selection of the shading device, given the designer's daylighting objectives, is better achieved. Existing shading devices are also able to be analyzed from a building designer's perspective. This analysis is based on the… Advisors/Committee Members: Beliveau, Yvan J. (committeechair), Suchicital, Carlos T. A. (committee member), Thabet, Walid (committee member), Jones, James R.

Abstract Today, digital imaging is widely used in dentistry. In medical radiography, the importance of displays and room illuminance has been shown in many studies, whereas the effect of these factors in the diagnosis of dental radiography is not clear and remains controversial. There is limited knowledge among dentists as to how observer performance is affected by the type of display, level of ambient light or grayscale calibration. The aim of this thesis was to compare observer performance in the detection of both anatomical structures and pathology in panoramic and bitewing radiographs using consumer grade display with γ 2.2- and DICOM-calibration, a tablet (3rd generation Apple iPad® and a 6 MegaPixel (MP) display under different lighting conditions. Furthermore, the thesis aimed at providing recommendations for type of display and acceptable illuminance levels in the room for interpretation of dental radiographs. Thirty panoramic and bitewing radiographs were randomly evaluated on four displays under bright (510 lx) and dim (16 lx) ambient lighting by two observers. Both anatomical structures and pathology were evaluated because they provided both low- and high-contrast structure. Consensus was considered as reference. Intra- and inter-observer agreement was determined. The proportion of equivalent ratings and weighted kappa were used to assess the reliability. The level of significance was set to P<0.05. DICOM calibration may improve observer performance in the detection of pathology in panoramic radiographs regardless of the room illuminance level. DICOM calibration improves the detection of enamel and dentinal caries in bitewing radiographs, particularly in bright lighting conditions. On the other hand, in dental practice the room illuminance level is often higher, and it is thus recommended that the overall lighting level should be decreased. Furthermore, a DICOM-calibrated consumer grade display can be used instead of a medical display in dental practice without compromising the diagnostic quality and it saves costs. Tablet displays are recommended to use with care in dental radiography.

Tiivistelmä Hammaslääketieteessä käytetään nykyään pääasiassa digitaalista kuvantamista. Lääketieteellisessä radiologiassa näyttöjen ja käyttöympäristön valaistuksen merkitys kuvien katseluun on osoitettu lukuisissa tutkimuksissa, kun taas hammaslääketieteellisten tutkimusten tulokset näiden tekijöiden vaikutuksista röntgenkuvien tulkintaan eivät ole yksiselitteisiä ja niissä on ristiriitaisuutta. Hammaslääkäreiden tiedot näyttöjen, kalibroinnin ja ympäröivän valaistuksen vaikutuksesta röntgenkuvan tulkintaan ovat puutteellisia. Tämän väitöskirjan tarkoituksena oli vertailla näyttöjen suorituskykyä panoraama- ja purusiivekekuvien tulkinnassa eri valaistusolosuhteissa. Tutkimuksessa vertailtiin γ 2.2- ja DICOM-kalibroitua perusnäyttöä, tablettia (kolmannen polven Apple iPad®) sekä 6 MegaPikselin (MP) lääketieteelliseen käyttöön tarkoitettua näyttöä.

The main objective of this research was to evaluate the internal conditions of the environment in two commercial broiler houses equipped with two different cooling systems: wet cellulose pads associated with nebulization (SRPN) and wet black screen pads associated with nebulization (SRSN). In the broiler houses, located in ItaberaÃ-GO country, the broiler production and human working environment was evaluated using variables related to thermal, acoustic and luminous environment and variables related to physiological responses and productive development of the poultries. Based on thermal confort indexes, it was concluded that broilers were under stress conditions during the hottest hours of the day (10 a.m. to 6 p.m.) in both broiler houses evaluated. Moderate stress condition was verified for the workers continuously explored to the broiler house internal environment. The sound pressure and illuminance levels were below the threshold recommended for humans according to Brazilian and internationals legislations.

O objetivo principal desta pesquisa foi a avaliaÃÃo das condiÃÃes do ambiente interno em dois galpÃes comerciais de frangos de corte equipados com dois sistemas de resfriamento diferentes: placas porosas umedecida de celulose associado Ã nebulizaÃÃo (SRPN) e placas umedecida de sombrite associada a nebulizaÃÃo (SRSN). Nos galpÃes, situados no municÃpio de ItaberaÃ - GO foi avaliado o ambiente de produÃÃo de frangos de corte e de trabalho humano por meio das variÃveis relacionadas ao ambiente tÃrmico, acÃstico e luminoso e, Ãs respostas fisiolÃgicas e ao desempenho produtivo das aves. Conclui-se que para as condiÃÃes tÃrmicas ambientais apresentadas, com base nos Ãndices de conforto tÃrmico, os frangos de corte estiveram em condiÃÃes de estresse por calor nos dois galpÃes avaliados, nas horas mais quente do dia (10h00min Ãs 18h00min) e em relaÃÃo aos trabalhadores avÃcolas, ambos os galpÃes apresentaram valores mÃdios considerados moderados para exposiÃÃo continua ao ambiente interno. Os nÃveis de pressÃo sonora e iluminÃncia estiveram abaixo dos limites mÃnimos recomendados para seres humanos de acordo com a legislaÃÃo brasileira e aquelas adotadas internacionalmente.

▼ In this thesis, the author developed a retroreflective sheeting selection technique for traffic signs. Previous research was used to determine the luminance needed by drivers (demand luminance). The author used roadways scenarios to determine the amount of luminance the retroreflective sheeting on a sign would produce (supply luminance). A spreadsheet was developed to determine the performance of different retroreflective sheeting types by comparing the demand and supply luminance for specific roadway scenarios. Using the results of previous studies, three demand luminance levels were created: replacement, adequate, and desirable. The replacement level represents the level of luminance when a sign needs to be replaced and is 2.5 cd/m2. The adequate level is the recommended amount of luminance when installing new traffic signs and is 10 cd/m2. The desirable level is the approximate level when additional luminance has diminishing returns and is 30 cd/m2. Supply luminance on a specific traffic sign was determined by evaluating roadway geometries, sign placement, retroreflective sheeting type and vehicle data. The author reviewed roadway geometries in Texas to estimate typical number of lanes, shoulder widths and horizontal curvature in the US. Sign placement from the MUTCD determined the typical lateral placements, sign heights, and sign twists. Vehicle data included vehicle dimensions and headlamp type. Both the supply and demand luminance were determined for a specific viewing distance for a given scenario. The viewing distance is the distance a driver needs to read or recognize a sign to respond properly. In addition, the type of sign, alphanumeric or symbol, determined how this distance was calculated. The author developed four sign groups to calculate the distance required to read and respond to a traffic sign, including 1) Stop required, 2) Reduction in speed required, 3) Read the message provided, and 4) Change of lane required. For symbol signs, the minimum required visibility distance (MRVD) was determined for the sign group and for text signs, the viewing distance at a legibility index (LI) of 30 ft/in was found. At these distances, the author calculated the supply luminance and then compared it to the demand luminance levels to determine the performance level. The author developed the Retroreflective Sheeting Selection Spreadsheet (RSSS) to allow others to use the methodology presented in this thesis. RSSS allows users to input the roadway data, vehicle data, and sign data. RSSS takes this information and looks up the supply luminance for the scenario. RSSS then compares the supply luminance to the demand luminance levels and outputs the retroreflective sheeting performance level for the scenario. Advisors/Committee Members: Hawkins, Harvey G.

▼ In lighting design, several different variables are measured, such as illuminance. Measuring these values requires different types of measuring instruments, either static measuring instruments or portable measuring instruments. Depending on the make, the same type of measurement can be measured in different ways. A static measuring instrument is usually measured one time at a specific location, while a portable measuring instrument can, for example, measure every minute or every ten minutes for an extended period. With constant research and technological development, the measurement of lighting variables has become more relevant. It is problematic to conduct experiments with a lack of consistent and accurate methods when measuring light. It is important to have the right conditions for a measurement in order for the results to be of good quality. The purpose of this study is to investigate differences between different static and portable measuring instruments used to describe the exposed illuminance and the physical activity. This is done through a pilot study. The pilot study was conducted using an experimental quantitative method with two participants during one day in four different measurement occasions with six different measuring instruments, the measuring instruments being measured in vertical, horizontal and flexible positions. The analysis showed that the results largely depended on whether a static or portable measuring instrument was used. The results also showed that depending on what position the measuring instruments measure from, the results vary. Based on the results, the conclusion is that the closer to eye level one can get, the more relevant the results are. For further research, all the measuring instruments used in the study should be calibrated prior to implementation. For example, it is important to examine the sensitivity of the measuring instruments when measuring indoors and outdoors. More participants, more measurements and more contexts would have been preferable for further research.

▼ Os sistemas de iluminação que utilizamos nas nossas tarefas diárias são um fator importante para o desempenho visual. Estes sistemas devem ser adequados às necessidades visuais exigidas por este tipo de tarefa. O objetivo deste estudo foi analisar a influência de determinados parâmetros da iluminação, nomeadamente a iluminância, cor e temperatura de cor, nos parâmetros acomodativos oculares. Foram avaliados 26 sujeitos com idades compreendidas entre os 18 e os 35 anos, sem problemas acomodativos e com visão das cores normal. Primeiro, determinou-se o erro refrativo, os parâmetros acomodativos e de visão binocular de todos os participantes. De seguida, os parâmetros acomodativos foram determinados em diferentes condições de iluminação. Foi medida a amplitude de acomodação e flexibilidade acomodativa em diferentes níveis de iluminância (30lx, 150lx e 400lx), iluminação colorida (verde e vermelho) e em iluminações com diferentes temperaturas de cor correlacionada (2500 K e 4500 K) que procuravam mimetizar condições de luz do dia para temperaturas de cor correspondentes. Para a realização das medidas sob diferentes condições foi utilizada a lâmpada Ledigma (Ledigma Ltd, Vilnius, Lithuania). Na variação da iluminância, verificou-se um aumento estatisticamente significativo na amplitude de acomodação dos 30lx para os 150lx (p<0,001; t-student test). A amplitude de acomodação medida com a iluminância de 400lx também apresentou um aumento estatisticamente significativo (p<0,001; t-student test) quando comparado à obtida com iluminância de 30lx. Contudo a amplitude de acomodação medida com a iluminância de 150lx não apresentou diferenças estatisticamente significativas quando compara à obtida com a iluminância de 400lx (p>0,05). Em termos de flexibilidade acomodativa, esta apresentou um aumento estatisticamente significativo dos 30lx para os 400lx (p<0,001; t-student test). Relativamente à iluminação colorida, os valores de amplitude de acomodação apresentaram uma diminuição estatisticamente significativa com a iluminação vermelha, quando confrontados com os obtidos com a luz branca (p=0,016; t-student test). A amplitude de acomodação medida sob a iluminação vermelha, apresentou uma diminuição estatisticamente significativa quando comparada com a obtida com a cor verde (p<0,001; t-student test). No entanto, a amplitude de acomodação medida com a luz de cor verde não apresentou diferenças estatisticamente significativas quando comparada à obtida com a luz branca (p>0,05). Em termos de flexibilidade acomodativa, não foram encontrados valores estatisticamente significativos (p>0,05; t-student test) para as condições testadas. O mesmo aconteceu com a temperatura de cor, em que não foram encontrados valores estatisticamente significativos entre os 2500 K e os 4500 K (p>0,05; t-student test). Os resultados encontrados sugerem uma associação entre alguns parâmetros acomodativos e condições de iluminação específica. Iluminação imprópria ou com parâmetros desajustados podem causar uma variação nos… Advisors/Committee Members: Franco, Sandra (advisor), Linhares, João M. M (advisor).

▼ In contemporary architecture, architects are increasingly using exterior solar control screens such as perforated metal panels and louver systems to reduce solar heat gains for highly glazed facades. However, the specific geometry of these screens is often based on aesthetics and not on energy performance or indoor environmental quality considerations. As a consequence, not all of geometries are capable of providing the level of solar and glare control required and are thus retrofit with additional façade layers that serve to limit the original daylighting and view objectives on which the façade was originally based. This is particularly true for 2‐dimensional systems, such as perforated metal screens. Because of this reason, the hypothesis of this research is that three‐dimensional systems can lead to better energy and IEQ performance outcomes compared with two‐dimensional geometry. For early phase design, overall performance of fenestration not only depends on parameters which include glare discomfort probability, useful daylight illuminance and solar radiation, but also refers to visual connection to the outdoors (view). Nevertheless, commonly existing researches did not examine view with other performance parameters simultaneously, but architects concern the outcome of view more than the effect of other parameters. Thus, the research examined the geometries in 2D and 3D dimension with four parameters including view, DGP, UDI and solar radiation. The perforated screen represented 2D base case and the louvers were 3D tested case. The measurements were simulated in Los Angeles and Seattle by Ladybug and Honeybee, and the louvers were from 0° to 75° in matte and specular materials. To develop the concept of design guide, the weighted score by linear transformation ranked the overall performance of those geometries, and the paired comparison was used for understanding potential sacrifices. As a result, when the opening was south‐facing, the louvers worked better than the perforated screen. In terms of design concept, for an architect, the best performance is the horizontal louver in Los Angele and Seattle except for considering both of view and glare in Seattle, and the exceptional louver is in 45 degrees. For an engineer, the best performance is the louver in 30 degrees in Los Angeles, but the louver in 45 degrees is better choice in Seattle. The potential sacrifice is glare issue based on the architecture choice, and part of illuminance maintenance might loss in terms of the engineering option. Based on the simulated measurement, the overall performance in three dimensions is better than it in two dimensions, and the results provide concept to develop the design guide in specific requirements to correspond with environmental conditions.

▼ This study evaluated the usefulness of a psychophysical model as part of a new ANSI/HFES 100 standard for CRT flicker. A graph based flicker prediction method developed from Farrell, 1987 was evaluated. The Farrell model is based on phosphor persistence, screen luminance, display size, and viewing distance. The graph based method assumes a worse case scenario (i.e. a white display screen shown on a display with P4 phosphor). While the Farrell model requires photometric measurements to be taken using special equipment, the graph based method require a knowledge of the display size, viewing distance, screen luminance, and refresh rate. Ten participants viewed different display sizes from different eccentricities under different levels of illumination and luminance. In each condition the display's refresh rate was manipulated using the Method of Limits to determine the critical flicker frequency (CFF). An Analysis of Variance was used to detirmine significant effects on CFF. CFF increased with increasing luminance and display size. Adequate illumination significantly increased CFF. A viewing eccentricity of 30 degrees (measured horizontally from the center of the screen) produced the highest CFF values. Under the conditions of 30 degrees eccentricity and 250 to 500 lux illumination, observed 50% CFF threshold values exceeded the 90% CFF threshold values predicted by the graph based method. This study demonstates that when tested under the same conditions it was developed under, the Farrell method successfully predicts flicker perception; however, when tested under conditions representative of real world working conditions, the Farrell model fails to predict flicker perception. New parameters for the model are suggested.<INPUT TYPE="hidden" NAME="abstract" VALUE="This study evaluated the usefulness of a psychophysical model as part of a new ANSI/HFES 100 standard for CRT flicker.

A viewing eccentricity of 30 degrees (measured horizontally from the center of the screen) produced the highest CFF values. Under the conditions of 30 degrees eccentricity and 250… Advisors/Committee Members: Beaton, Robert J. (committeechair), Prestrude, Albert M. (committee member), Deighan, John (committee member).

▼ Although daylighting has been recognized as an important means of improving the energy efficiency of buildings, and despite the value that building occupants place on it, fundamental questions need attention: (1) The daylight factor, the performance indicator most commonly used in design and research, has several serious limitations. (2) Simplified methods of daylighting estimation, such as scale-model photometry and computer simulation, are used extensively in daylighting design and research, although very little has been done to evaluate the accuracy of these techniques. (3) Research results are often conveyed in forms which make them difficult for architects to use in practice. It is shown that a new indicator of daylighting performance, the VH ratio, is superior to the daylight factor. Specifically, it: (1) is less subject to misleading variations, (2) remains usable under clear and partly cloudy skies, (3) provides a measure of qualities such as glare and directionality of illumination, (4) is easier to determine under real skies, and (5) can be applied to combined daylighting-electric lighting systems. The VH ratio is defined as the ratio of the illuminances on a pair of vertical and horizontal planes passing through a single point in a space. Comparative evaluation of the VH ratio and the daylight factor was performed by making photometric measurements in full-scale spaces with five different window types. Measurements were made under overcast, clear, and partly cloudy skies. The accuracy of scale-model photometry and computer simulation was assessed by comparing estimates provided by these techniques with full-scale photometric measurements. It appears that the luminance distributions of real skies may deviate widely from standard sky luminance distributions, leading to discrepancies in computer-generated estimates. Other sources of error in scale-model photometry and computer simulation are discussed. It is also shown that typical open-plan furniture systems can reduce illumination from daylight by 30 percent, compared with reductions of 10 percent found in similar studies of spaces with electric lighting.
