▼ Clothing comfort is defined by the tactile sensations felt by a subject through the mechanical interactions between the body and the garment. This research investigated the mechanical properties of 100% woven cotton fabric that significantly contribute to the perceived in-wear comfort of garments treated by various laundering methods. Treatments included washing methods using detergents and softeners, as wells as after treatments with selected starch applications. The treated fabric samples were initially assessed via development and execution of a hand panel consisting of 26 females. Mechanical properties of the samples were measured using the Kawabata Evaluation System. A comparison of hand ratings and KES properties of each treatment showed a significant difference between treatments. Subjects were not able to perceive a difference between two of the treatments and after testing of other treatment methods a sample set was selected for a wear test. Four of the nine bipolar descriptors correlated well with overall hand ratings including harsh/soft, rough/smooth, sandy/slippery, and rigid/flexible. The hand panel results were employed to design a full garment wear test. The same fabric was used for manufacturing button down blouse garments of varying sizes to fit the human subject panel of 29 females. In this experiment, subjects performed four activities of controlled dynamic movements and rated the garment after each activity. The activities included: donning where subjects simply changed into garments; arm crosses where subjects switched the position of two small weights on a counter top by crossing their arms; toe touches to arm raises in one continuous movement; and bowling where subjects played a bowling game on a Nintendo Wii systems that required subjects to make bowling motions with one arm. Correlation models were then developed for the dynamic garment wear test and Kawabata measurements. The type of dynamic movement performed had a significant effect on comfort ratings. A final model was constructed correlating mechanical properties to descriptors which were correlated to overall comfort. The descriptors significant to predicting overall comfort were scratchy and stiff which were included in the model with the activity type. The mechanical properties geometric roughness, coefficient of friction, and mean deviation of coefficient of friction were correlated to the descriptor scratchy and the mechanical property shear stiffness was correlated to the descriptor stiff. Locations of sensation were identified during each activity and will be used in further wear testing to measure dynamic properties.

▼ This study evaluates the use of international thermal comfort standards currently being used in the south terminal of the King Abdulaziz International Airport (KAIA). The airport is located in Jeddah, in the Kingdom of Saudi Arabia (KSA). The study was prompted by the hypothesis that the hot climate experienced in KSA, the acclimatization of those in the region, coupled with the widespread wearing of traditional clothing, justifies a unique model of thermal comfort. The south terminal of KAIA currently uses set points of 20-24 °C (ASHRAE-based comfort model). Most international thermal comfort standards are based on experiments that were conducted in moderate climates. These studies have two particular shortcomings in the context of those living in hot climates: they fail to consider that people in other climatic regions could have different thermal expectations and preferences, and many disregard the role of outdoor temperature on thermal comfort. The international standards prescribe temperature set points that are often too low for people who live in extremely hot and humid climates. Keeping the temperature at the international set point requires excessive amounts of energy and is wasteful and expensive. Public policy demands that the thermal control strategies in public buildings be evaluated to ensure that they are operating efficiently. Airports are of particular concern because they have HVAC systems that consume a disproportionate amount of energy relative to their size. This study, based on passenger surveys and energy simulation, considers the effectiveness of developing a model of thermal comfort as an alternative control strategy for the KAIA terminal and assesses its energy impact. In order to determine new temperature set points that might better serve the needs of the passengers and maximize energy efficiency in KAIA, this study: a) Conducted detailed surveys of passengers in the airport terminal; b) Obtained measurements of both physical and personal variables; c) Recorded behavior patterns of passengers; d) Collected all relevant data on the conditions inside and out of the terminal; e) Considered the impact that traditional garments may have on thermal comfort; f) Used the data from the surveys to create a new model of thermal comfort; g) Used computer simulation programs to test and compare a developed thermal comfort model with the set point currently used in the building. The results of the survey demonstrate the unsuitability of the ASHRAE-based comfort model (set temperatures of 20-24 °C) currently used in the airport. The data from the survey is used to derive new models of thermal comfort using regression analysis. Computer simulation demonstrated that the new set comfort temperatures obtained from created models could significantly increase the operational efficiency of the terminal. Implementing these models would also reduce the operating cost of the KAIA, lower the CO2 emissions and improve the comfort of passengers. More particularly, the results of the research demonstrate the…

▼ Outdoor thermal comfort is key to creating vibrant outdoor urban spaces. The built form is able to modify solar radiation and wind. However, there is currently no way of considering the effect of the built form on thermal comfort when designing a new development based on the environmental factors – wind, solar radiation, and ambient temperature. Current practice for designing outdoor thermal comfort is based on simple design guidelines, and knowledge of local wind and sun patterns. A Process for Predicting Outdoor Thermal Comfort has been developed. This predicts thermal comfort based on solar radiation, wind, and ambient temperature using The Wellington Comfort Index. The process is able to predict comfort at a single point within a proposed urban development using specialised computer programs. Through predicting how the combination of solar radiation, wind, and ambient temperature will affect comfort, improvements can be made to comfort during the design phase. The aim of this thesis project is to develop the Process for Predicting Outdoor Thermal Comfort into a Comfort Tool for use at the preliminary design stage of a development. The intended users of the tool are professionals working in urban planning and architecture, such as designers and consultants who have experience with three-dimensional modelling and simulation programs. A case study research approach was used to test The Comfort Tool’s ability to inform design changes through communicating thermal comfort across a proposed development. A range of case studies were selected with different built forms. This was to test if The Comfort Tool can predict comfort in case studies with different levels of solar radiation and wind at pedestrian level due to the variations in the built forms. This research confirmed that a tool can be developed for predicting comfort across a proposed development, which can also test proposed design changes for their success during the design phase. However, further investigation is needed to determine whether The Wellington Comfort Index can be used in other cities. Advisors/Committee Members: Dunn, Michael.

▼ Animal welfare is very important these days. Consumers are more aware of what they eat and demand for transparency of production of animal production. Farmers also want their animals to live a good life. It is well known that poor health and poor housing cause stress to cows and stress will lower the milk production. So the current idea is that good cow comfort will result in better milk production. In this study, the cow comfort of 36 farms was scored using the Cow Comfort Scoring System and the total score and all chapters and items of this system were compared with milk production parameters. The parameters used are the Fat Corrected Milk production (FCM), milk fat percentage and milk protein percentage. The total score of the system did not correlate at the 0.05 level with the FCM (P = 0.096 and R = 0.295). But since the data used for the biggest chapter of the scoring system, animal health and feeding, was not very reliable, the score for this chapter was excluded and the trend became more clear and the correlation larger; the P of FCM goes to 0.073. The correlation between the total scoring and the milk fat percentage also became larger this way; the P went from 0.568 to 0.162. Comparison of the FCM with the cow comfort chapter and items showed several significances. FCM was significant with the chapter water (P = 0.012; R = 0.431), the item number of water places (P = 0.015; R = 0.420) and the item contamination of the feeding (P = 0.008; R = 0.456). There also was a correlation between FCM and the item claws (P = 0.001; R = 0.536). Furthermore, there was a negative correlation between FCM and the items period of light (P = 0.026; R = -0.388) and period of darkness (P = 0.006; R = -0.470). The milk fat percentage was negatively correlated to the chapter light (P = 0.013; R = -0.427) and the item sufficient light (P = 0.045; R = -0.346) and the milk protein percentage was negatively correlated to item claws (P = 0.023; R = -0.454). The hypothesis of this study was that the milk production parameters would be correlated to the total score of the Cow Comfort Scoring System and possibly also to the different chapters and items of the system. But only a few significant correlations were observed and some of the correlations are not clear yet. This is because during this study, only 36 farms could be scored. To draw proper conclusions, a larger number of farms is necessary. Advisors/Committee Members: Eerdenburg, F.J.C.M. van.

Since the early 2000s, I have created a number of complex intercultural, large-‐scale and site-‐specific works that have often addressed the racial and political tensions experienced by communities disadvantaged and marginalised by their low socio-‐ economic status. These works have employed a range of theatre-‐making strategies often described as avant-‐garde or experimental, but more recently understood in terms of the ‘Postdramatic’, a term coined by German theatre scholar, Hans-‐Thies Lehmann (2006). The research paper seeks to elucidate the ideas of comfort and discomfort that are the focus of the performance/lecture, The Comfort Zone, and which are discussed not only in terms of my MCA-‐R project but also three of my earlier works, understood as fundamental to my development as an artist and which have led directly to the development and presentation of The Comfort Zone. It does so through a discussion of ‘the poetics of failure’ as articulated by UK-‐based academic, Sara Jane Bailes (2010) and the ethics of spectatorship as discussed by Australian theatre scholar, Helena Grehan. The three earlier works are: Sleeplessness produced and presented by Performance Space, Sydney in 2003; Gathering Ground: History, ceremony, protest, commissioned and produced by PACT Theatre and Redfern Community Centre, Sydney in 2006; and The Riot Act produced and presented by Campbelltown Arts Centre and Blacktown Arts Centre, Sydney in (2009). This paper also discusses how my research on comfort has been used as a catalyst for the transformation of my practice, through an analysis of the processes of creating and presenting more recent works including: The Comfort Zone (2011), The Hunting Party (2012) and FUN PARK (2014).

▼ This research concentrates on creating wellbeing by performance; behaviour and technical performance of materials and products in office buildings. This research is focused on the case study conducted at; the headquarter of a bank in the Netherlands, whereby the building users are criticizing the indoor comfort. Moreover, the building materials are end-of-life and the building is using a large amount of energy. The following research question is answered: ‘How can the indoor comfort be improved in a circular way, by creating an optimal floorplan including the interior and technical aspects for, the case study, one pilot floor of the headquarter of a bank in the Netherlands, while taking the energy consumption into account?’ Within this study different research methodologies are applied. The first research method is literature study and reference projects to gather knowledge about the indoor comfort with the following possible stressors; indoor air quality, thermal comfort, light and visual quality and acoustic comfort and circularity within the building environment. This information is derived from the Dutch regulations, certification rating systems, the case study and articles with the same theme. The literature study and reference projects are analysed to draw up criteria which the measurements and the design of the floorplan must meet. The second research method is material analyses to identify the materials and products which are used in the interior of the case study and how they can be improved to contribute to the indoor comfort, circularity and energy efficiency. The third research method is analysing the existing survey conducted in 2019 by the company Leesman. Analysing this survey can profile the building users and rate the satisfaction level of their workplace, activities, and facilities. The last research method is analysing the performed measurements. To study the current situation of the case study by testing the indoor comfort stressors on the criteria prepared with literature study and reference projects. These measurements are performed with 24 GreenMe cubes which records the indoor comfort values every ten minutes for three weeks, which resulted in 3024 measurement points within ten categories of the indoor comfort stressors. The research results are translated into a circular and indoor comfort framework and floorplan design including the interior and technical aspects. The analyses results show that it is desired to renovate the headquarter of the bank in the Netherlands. This conclusion is based on the following results of this study, first of all most of the materials and products are not demountable. Therefore it cannot be cleaned well and it pollutes the air. Moreover, it is not fully circular when only the materials are obtained sustainable, but cannot be reused or remanufactured after its first lifecycle, when they are not demountable or additives are added. Secondly, the building users are not satisfied with the indoor comfort within the headquarter of the bank.

▼ This PhD thesis looks at the issue of heating historic churches. These structures pose particular challenges: they consist of large high volumes, they are composed of materials that are vulnerable to changes in indoor microclimate, they usually possess fabric of low energy efficiency, it is often very difficult to insert new systems without damaging the historic fabric, and they are only very intermittently occupied. Churches are thus particularly difficult to heat satisfactorily; most early churches were entirely unheated. Later, local heating, such as stoves, were introduced to respond to congregations’ demand for comfort. Newer churches then started being built with heating systems from the start. Although these were rarely satisfactory, modern solutions have generally either attempted to provide low-level continuous background heating or concentrated on heating the congregation or a combination of the two. This thesis starts by looking at existing systems for heating churches and the current literature used to establish so-called best practice. It then sets out to investigate whether these solutions are actually working. It starts by establishing the ideal environmental conditions for conservation of the fabric. It uses existing literature on the conservation of museum artefacts, looking at each material found in churches in turn to map the various requirements and see if a set of conditions can be found that will ensure preservation of all the materials involved. Next, the thesis uses monitoring to establish what conditions actually exist in historic churches. Four churches in Cambridge were chosen to conduct an on-site survey. The four case studies adopt different modern heating solutions and each was carefully monitored throughout the year to establish what the exact conditions were. At the same time the thesis recorded thermal comfort and energy performance. There has been no study that brings together information on proper environmental conditions for protection of all the various categories of materials, perceived thermal comfort and energy performance in church buildings so this thesis sets out to provide one. The thesis shows that most modern heating strategies for historic churches fail to satisfy all three strands of environmentally sustainable performance indicators for church buildings, i.e. energy performance, thermal comfort, and the preservation of the historic fabric. It ends by tentatively suggesting how these challenges might be approached. The final section of the thesis details the limitations of the study and the various areas that require further study. Overall the study seeks to provide a useful survey of the existing literature on the subject and raise some important questions about the current strategies being employed for heating historic churches. Although the study is restricted to examples in a relatively small geographical area, the conclusions could be applied generally to other Northern European examples and the implications apply not only to other churches but also similar…

In 2013, national agreements have been made to stimulate a healthy and sustainable growth of the Dutch society and economy. These agreements include that, on average, all buildings need a label A by 2030. However, the calculated energy savings for all energy labels do not correspond with the actual energy savings, which is partly due to user behavior. The occupants, not buildings, are the primary energy consumers because they behave proactively and to perform energy related tasks in order to seek comfortable personal conditions. The general aim of this research is to advance the knowledge base on ways of saving energy and increase indoor air quality by addressing user behavior characteristic with an automated building product. This study could offer alternative options for energy saving methods and thereby contribute to the current efforts in sustainable design research. By providing knowledge on thermal loss due to user behavior, occupants can implement such strategies to create more comfort while reducing their energy consumption. This concept focuses on reducing the thermal loss due to the increase of the air change rate resulting from window operation. The additional energy consumption due to window operation during heating season can be significant, but is difficult to quantify. Ventilation and window opening characteristics become more important due to renovation trends favoring air tight buildings. These high performing and air tight buildings can lead to an indoor accumulation of air pollutants and high humidity’s, which can cause multiple health symptoms. A combination of calculations, simulations and prototype testing is used to determine a way of automating window operations in an ideal way. The final prototype is installed in the PDlab where it was used for testing its cooling and air cleaning potentials.

In our modern cities, the large majority of the activities take place indoors and training is no exception. Thermal comfort at high metabolic rates inside buildings is to be maintained as much as possible without sacrificing energy saving. Indoor thermal comfort level is the result of a combination of various parameters and air movement is one of them together with air temperature, air humidity and radiant temperature. Making use of localized airflows can compensate for the necessity of cooling a room. Most research, though, has been focused on people with low metabolic rate, meaning that more research on improving thermal comfort of people training is required. The aim of this study is to test how airflows with different characteristics and more specifically air velocity, turbulence intensity and power spectral density can improve thermal comfort of people training indoors. Training subjects were asked to evaluate themselves a number of different airflows. More specifically, human subjects were asked to exercise indoors using a cycling machine. At certain moments during this procedure airflows were introduced and subjects were asked to fill in a questionnaire concerning their thermal condition. This procedure was repeated for each of the airflows. This way, the impact of the three parameters mentioned above on the thermal condition of a subject training indoors could be evaluated. Before the experimental procedure described, the airflows to be experienced by the subjects had to be determined. Consequently, information about the pattern of the airflows created by various set-ups was gathered by recording and further analyzing the velocity value by time in different locations inside the airflows. Throughout this analysis, the most appropriate airflows for the experiments with human subjects were chosen. As reflected in the answers of the participants the introduction of the airflows had, in overall, a positive impact. Furthermore, the increase of the velocity and the turbulence intensity and the existence of power in frequencies higher than 0.1 Hz resulted in an increased cooling capacity. The increase in turbulence intensity and the existence of power in higher frequencies resulted, additionally, in a less pleasant for the subjects airflow. Based on the results, the optimum between the airflows could be selected as well.

▼ Heden ten dage zijn er onoverzichtelijk veel verschillende klimaatinstallaties. Deze installaties geven vaak problemen in verschillende fasen van het bouwproces, zo ook in de ontwerpfase. In dit werk is een selectie van meest voorkomende installaties in de woningbouw integraal onderzocht in haar omgeving om de thermische en energetische prestaties vast te stellen. Om deze installaties te kunnen onderzoeken is er voor gekozen om zelf een computermodel op te zetten op basis van de Eindige Elementen Methode, waarin zowel het bouwfysische als het installatietechnische onderdeel zijn gemodelleerd. Het model is iteratief in overleg met bouwfysische en installatietechnische adviseurs tot stand gekomen. Het model is gevalideerd met behulp van VABI, door handmatige nacalculaties, en door vergelijkingen met andere reeds voor handen zijnde referenties. Uit het computermodel blijkt dat de thermostaat van grote invloed is op het gewenste binnenklimaat. Veel thermostaten meten enkel de luchttemperatuur en regelen de installaties dus niet op basis van de operatieve temperatuur. Hierdoor slaan luchtverwarmingsinstallaties te snel af, terwijl vloer- en wandverwarming te laat afslaat. Bij een regeling op basis van de operatieve temperatuur is de opwarming bij vloerverwarming nog steeds traag ten opzichte van radiatoren, terwijl (lokaal opgewekte) wand- en luchtverwarming 15 tot 30% sneller verwarmt. Dit komt doordat de laatste twee de warmte direct afgeven aan het vertrek, terwijl de ‘zware’ installaties eerst een watervoerend pakket en andere massa moeten verwarmen. ‘Zware’ installaties kennen dan ook nog steeds meer overshoot en energiegebruik als gevolg daarvan. Luchtverwarming gebruikt meer energie, omdat deze een ventilator gebruikt. Elektrische wandverwarming kent vergelijkbare energetische prestaties als radiatoren. Een warmtepomp (WP) verbruikt de minste primaire energie, maar kent zo een laag vermogen dat ze continue aan moet staan voor een goede verwarming. Tevens hebben ventilatie-installaties als warmteterugwinning (WTW) en vraagsturing (VS) invloed op de opwarming en het energieverbruik. VS zorgt ervoor dat er voor dat er bij afwezigheid maar 10% warmte verloren gaat t.o.v. 30% bij WTW en warmt dus sneller op. WTW kent echter minder energieverbruik, omdat deze ook bij aanwezigheid functioneert en dan ook tot 70% van de warmte terugwint. Onderzoek naar gebruikerspatronen heeft opgeleverd dat het continue laten aanstaan van de verwarming in een goed geïsoleerd gebouw 10 tot 15 % meer energie kost. Het kost slechts 1% wanneer ook WTW wordt toegepast. Tenslotte blijkt voor de zomer van belang dat er warmere zomers bestaan dan waar de normen nu rekening mee houden en die dus regelmatig overschreden worden. Verder blijkt het vermogen van koeling ontzettend van belang, omdat temperatuuroverschrijding vaak met grote warmtelasten gepaard gaat. Men moet tevoren preventief koelen om aan de normen te voldoen. Als het koelvermogen dan ook nog gering is, zoals bij een WP het geval is, is het moment dat de WP aanvangt met koelen vaak al… Advisors/Committee Members: Van den Dobbelsteen, A.A.J.F.

▼ The scope of “Evaluation of alternative approach for suspension corner damping by the use of hydraulic top mounts” is the analysis of the benefit given by the implementation of a hydraulic mount as the top mount for a vehicle suspension system. The whole project is based on numerical simulations performed by means of MATLAB®/Simulink®. Therefore, the modelling of the selected hydraulic top mount by means of a system of springs, dampers and masses was the starting point of the project. Afterwards, the aforementioned hydraulic top mount model was inserted into a quarter car model and its performance was compared to that of an equivalent quarter car model employing a rubber top mount, instead. Therefore, the quarter car model with the rubber top mount represented the reference model to assess the performance of the new hydraulic top mount. In particular, both linear and nonlinear quarter car models were developed, the former were used to check the robustness of the model itself and the latter were used to carry out all the comparisons with the reference models. Different chirp signals were used as input for all the linear models, while random road and single asperity signals were employed as inputs for the nonlinear models. Furthermore, in order to explore the potential improvements that could be achieved by implementing the hydraulic top mount, a second arrangement for the relative position of the hydraulic top mount and the shock absorbed in the quarter car model was modelled and, then, tested. A slight better performance was recorded in the case of models containing the hydraulic top mount. Finally, for a better understanding of the characteristics of the hydraulic top mount, a Design of Experiments (DOE) that takes into account the parameters of the mount hydraulic components was carried out; DOE methodology allowed one to identify the most influential factors in the quarter car model performance. Additionally, the analysis of DOE results was employed as a starting point to perform a first optimization of the hydraulic top mount. The simulation carried out employing the optimized top mount showed a relevant improvement with respect to the base hydraulic top mount and, a fortiori, with respect to the rubber top mount case. Moreover, it was shown that the second arrangement for the hydraulic top mount in the quarter car model could give even better performance than the model with the standard arrangement.

▼ The extremities (hands and feet) are morphologically and physiologically well suited for the dissipation of heat (Taylor et al. 2014). However, unlike the hands, the thermolytic potential of the feet is often diminished when wearing footwear. Shoes act as a barrier to heat and vapour transfer between the skin and the environment. Thus when the wearer's dry and evaporative heat loss pathways are limited, heat and moisture may build within the air layers between the skin and the footwear (Havenith et al. 1990a; Sullivan and Mekjavic 1992; Bouskill et al. 2002). The combination of high temperatures and moisture accumulation contributes to perceptions of discomfort (Arezes et al. 2013; Irzmańska et al. 2013; West et al. 2019b), blister formation (Sulzberger et al. 1966) and encourages the growth of microorganisms which can lead to odour development and foot conditions such as tinea pedis i.e. athletes foot (Auger et al. 1993). Due to the complexities of assessing the thermal interactions within the foot-sock-shoe system, relatively little is understood as to how we subjectively evaluate this aspect of footwear comfort. Therefore, the aim of this research was to investigate the physiological and perceptual responses of the foot, the interactions within the foot-sock-shoe system and the impact on comfort. For this purpose, a multi-factorial, mixed methods approach was used to investigate regional variations in thermal sensation to warmth (Chapter 3), foot sweat production and distribution (Chapter 4), temporal and spatial characteristics of shoe microclimate (Chapter 5) and the role of the sock (Chapter 6 and 7) on perceptual responses relating to foot discomfort. The use of a thermal foot manikin as a tool for footwear evaluation and development was also examined (Chapter 8). Several findings emerged: 1) The feet play an important role in the modulation of whole body thermal sensation. 2) Foot sweat production is reduced when wearing shoes. Highest sweat rates occur at the medial ankle and dorsal regions; lowest sweat rates at the toes. 3) Shoe microclimate is significantly affected by shoe permeability. Although changes to shoe microclimate are perceivable by the wearer, thermal comfort must be considered as a function of both temperature and moisture accumulation within the shoe. 4) Although wearing/not wearing a sock does not elicit differences in thermo-physiological responses, the sock does play a role in minimising wear discomfort. 5) Tactile and mechanical inputs are important for the perception of skin wetness and discomfort within footwear. 6) The subjective evaluation of footwear does not achieve the same level of sensitivity or discriminative power observed with thermal manikin tests. Overall, this research provides a detailed insight into the physiological and perceptual responses of the feet and for the first time, provides insight into the interactions within the foot-sock-shoe system. Together, the findings from this research provide guidance for the development of thermally comfortable footwear.

▼ This thesis studies thermal comfort in heating, ventilation and air-conditioning (HVAC) scenarios with computational fluid dynamics (CFD) models at domain and occupant levels. Domain level comfort modelling, where the details of the occupant are not modelled, is investigated utilising Fanger’s Predicted Mean Vote (PMV) and Predicted Percentage of Dissatisfied (PPD) comfort models. Occupant level comfort modelling, where the occupant geometry and skin temperature are required, is explored using two different models. The first model termed the thermal manikin model couples the University of California Berkeley (UCB) psychological model to a new physiological model which neglects the thermal regulation of the human body, and consists of a central core at constant temperature surrounded by a layer with thickness and corresponding thermal properties to allow the skin temperature to vary over the modelled human body. The second model based on Gagge’s two-node model, which includes thermal regulation, yet assumes the skin temperature of the occupant to be spatially uniform. The models are validated with the experimental results from the Technical University of Denmark, which provides the data of the air flow, and the Indoor Environmental Quality (IEQ) laboratory at the University of Sydney, which offered the actual votes of human subjects for a range of environmental conditions. To conclude, the prediction of the skin temperature and its spatial variation is the most important parameter to predict occupant comfort correctly. The occupant level comfort modelling approach employing the thermal manikin is found to be the superior method to evaluate thermal comfort as it can still be accurate when the environment is complex. However, the computational cost and model setup time is high. Further work employing multi-node thermal manikin models would be a fruitful area of research if the accuracy of occupant comfort prediction in complex thermal environments is of interest.

▼ Dry eye is a highly prevalent disease causing symptoms of discomfort that are severe and disabling for many sufferers. One of the leading causes of the evaporative form of this complaint is believed to be Meibomian Gland Dysfunction (MGD). Although clinical manifestations of MGD are easily observed, the association between the morphology and function of the meibomian gland and the symptoms experienced by those affected, remains controversial. Better understanding of this relationship may help to predict those at risk and will contribute to development of effective treatments and preventative strategies.This thesis describes a series of studies designed to investigate the relationship between subjective ocular symptomatology and both meibomian gland morphology and function.Grading scales commonly used to assess meibomian gland morphology and lid wiper epitheliopathy were validated and found to offer only moderate sensitivity to detect changes. Objective assessment systems incorporating image analysis software were developed which permitted highly repeatable and accurate assessment of meibomian gland morphology and lid wiper epitheliopathy.The Korb meibomian gland evaluator and the meibomian gland forceps were identified as the optimal meibum expression methods.Tears and meibum were collected and analysed using nano-electrospray, mass spectrometry. These techniques were able to identify and quantify the major classes of component lipids. The lipid profiles derived showed good repeatability, both within and between days. A comparison between tears and meibum showed them to have similar lipid profiles, apart from phospholipids, which occurred roughly four orders of magnitude more abundantly in tears. This confirmed that meibum is not the major source of phospholipids in tears.No clear relationship between meibomian gland morphology and symptoms of discomfort was found, with the possible exception that meibomian gland coverage of the upper lid is reduced in those with more severe symptoms.For meibomian gland function, weak to moderate associations between ocular symptomatology and the position of Marx’s line and the frequency of eye rubbing were observed. Meibum quality and the relative proportion of (O-acyl)-omega-hydroxy fatty acid (OAHFA) in tears were found to potentially discriminate those with the most severe symptoms from the rest of the sample.

▼ This thesis investigates adopting the courtyard pattern in Iraq to provide a thermally efficient architectural solution that contributes towards solving the housing challenges in the country. As a result of more than three decades of wars and instability, the country suffers from having a large housing shortage and a major production shortfall. This shortage is estimated at around 1.0 million housing units, which is equivalent to one-quarter of the total housing stock in the country. The current housing production is around 30000 housing units per annum only, which, therefore, does not alleviate the housing needs in the country. The country has developed a new national housing policy and adopted the mass construction of multi-family buildings as an architectural solution towards solving the large quantitative problems. This research aimed to investigate the potential thermal efficiency of courtyards with considering this housing context. To achieve this aim, this research started by investigating the housing context in Iraq. It, then, focussed on the use of courtyards in modern multi-family residential buildings in Iraq, and explored the level of thermal comfort that courtyards can offer to Iraqi residents. The study developed a novel Courtyard Thermal Usability Index (CTUI) to quantify the ability of courtyards to offer a thermally comfortable environment to occupants. CTUI is the fraction of thermally comfortable hours in a courtyard to the total occupation hours during a specific period. To underpin the quantification, the research conducted a thermal comfort survey in Iraq and carried out a series of simulation experiments. The aim of the survey was to determine the thermal comfort limits of Iraqis to be used in judging the thermal efficiency of courtyards. The aim of the simulation was to explore the thermal conditions of courtyards in Iraq. Two simulation tools, Envi-met and IES-VE, were used to determine the thermal conditions across a search space of 360 different courtyard variants. The simulation experiments were conducted for Baghdad and six other Iraqi cities of different climatic conditions. The tested courtyards represent a wide range of possible courtyard geometric configurations, which enabled the research to provide a good overview of possible thermal conditions of courtyards in Iraq. The survey results indicate that the minimum and maximum thermally comfortable globe temperatures for Iraqis in winter and summer are, respectively 14 °C and 35 °C. Within this comfort range and during the daily occupation hours, which are from 8:00 to 22:00, the annual CTUI of courtyards, in Baghdad, ranges between 0.16 and 0.38. Expressed in a different way, courtyards can offer 875 - 2078 comfortable hours out of 5470 occupation hours per annum. The rest are not comfortable hours, mostly due to overheating. In comparison to current typical urban settings, courtyards offer higher levels of thermal comfort. The most effective geometric property on courtyards’ thermal conditions and the level of thermal comfort in…

▼ Climate change has become a major concern for research and policy in recent decades, and housing has been an important area to tackle as globally this sector accounts for roughly a quarter of energy demand, and its resulting carbon emissions (Staffell et al., 2015). Behaviour change campaigns constitute a significant strand within government responses to reduce carbon emissions. However, on the grounds that environmental impact has little to do with individual’s intentions, there is growing interest in the ordinary, rather than the extraordinary (e.g. pro-environmental values), and the socio-material transformation of collective conventions (Shove, 2010). Research emerging from this ‘practice turn’ is often underpinned by evidence of changing expectations of comfort that undermine improvements in energy efficiency (Hitchings and Lee, 2008; Walker et al., 2016). Notably, research indicates that it is increasingly common for indoor environments to be maintained within a narrow range of temperatures through mechanical heating and cooling, which has significant implications for energy (Shove, 2003). While these practice-informed studies have successfully offered new avenues for intervention in sustainable consumption, home comfort has been rather narrowly investigated and has often been equated with thermal comfort. Yet expectations of home comfort and household management decisions are much more complex and multifaceted than the desire to be sufficiently warm or cool. A focus on thermal comfort has arguably trivialised other meanings of home comfort that might also be significant to understanding patterns of domestic energy demand. The aim of this thesis therefore was to develop a concept of home comfort to inform understandings, debates and policy related to domestic energy demand, and this thesis presents data from whole-household interviews, house tours, ideal drawings and home energy adviser interviews to address this aim. A key finding of this thesis was that home comfort is a sense of relaxation and wellbeing, which results from companionship and having some sense of control in the home. Broadening out understandings of occupant satisfaction to account for some of this complexity draws attention to householder’s perception of the space per person ‘needed’ to facilitate comfortably sharing the home with others. Engaging with the trend towards increasing space per person is important because it has the potential to reduce energy demand for space heating without falling back into emphasising technical intervention or questioning the standardisation of thermal comfort. Furthermore, householder’s actions to reduce domestic energy demand were found to be tightly, if implicitly, linked to expectations of home comfort and processes of homemaking. It is important to remember that changes to the home are not simply the result of financial rationalisation or attempts to improve thermal comfort. There is certainly scope for the concept of home comfort to inform understanding of domestic energy demand and to highlight… Advisors/Committee Members: Reid, Louise Anne (advisor), Hunter, Colin (advisor), Findlay, Allan M (advisor).

▼ Growing passenger dimensions and the demand for more comfort in the economy class cabin is a trend that is becoming more important during aircraft conceptual design. Based on recent investigations, it is known that current aircraft seat dimensions are not suitable and safe for a large part of the world population. Therefore, a change in aircraft conceptual design thinking, by taking human anthropometry into account, is required. This thesis investigates the opportunity to change the aircraft during conceptual design as well as the opportunity to change current aircraft in order to provide a higher level of passenger comfort and safety. To measure the latter, a comfort model is created, based on scientific research and human dimensions, allowing for the measurement of comfort related to seating configurations, seat characteristics, and cabin dimensions. By establishing the ideal seat dimensions, it is shown that conceptual aircraft designs for the worldwide 95 percentile passenger require wider, but shorter, fuselages. Using the Initiator as a conceptual design tool, four short-haul and four long-haul aircraft are modeled for a range of seat dimensions. Based on an inside-out aircraft design approach, it is shown that similar aircraft performance characteristics are obtained when designing for the worldwide 95 passenger percentile. Moreover, a similar level of direct operating costs, and hence profitability, is attained. However, designing for the worldwide 99 passenger percentile yields considerably higher fuel burn rates and operating costs. An average increase of 3.9 % among all modeled aircraft is seen for the harmonic fuel burn, leading to an increase of 4.2 % in direct operating costs. Considering existing aircraft, use is made of an outside-in aircraft design approach to assess a set of performance characteristics. Based on an average utilization of 37 % of the cargo space in commercial transport aircraft, a potential is shown for a different utilization of the aircraft lower deck, allowing the airline to provide more passenger comfort while retaining a similar level of profitability. Using the Airbus A340-300 as reference aircraft, it is shown that the placement of passengers in the lower hold is feasible from a regulatory, ergonomical, economical, and structural point of view. Based on a reference three-class layout with 267 passengers, it is shown that a lower deck seating compartment provides an increase of 14.6 % in the number of passengers when similar seat properties are used as on the main passenger deck. The installment of additional furnishing and required structural reinforcements results in a decrease of 12 % in maximum structural payload weight. Nevertheless, it is shown that the placement of passengers in the lower deck yields higher profitability rates for the airline when compared to the carriage of additional freight. Secondly, the placement of lavatories and galleys in the aircraft lower deck is investigated, allowing for a maximum increase of 13 % in passenger seats.

▼ Energy has been delivered to buildings and households to make sure rooms are comfortable for occupants. We currently think of this delivery in the isolation as it heats and cools individual spaces. The heating and cooling of buildings have consequently become more about hitting a setpoint instead of aligning the delivery of comfort to humans with the effective and readily available upstream sources. The thesis of this dissertation is finding the most effective pathway to supply comfort to people. The work begins with the examination of the fundamental assumptions of thermal comfort models using an exergetic approach to insert the occupants into the energy delivery chain. Second, the research examines how environmental parameters such as relative humidity and mean radiant temperatures are oversimplified in energy analyses. Finally, this is connected with the analysis of sourcing the supplied exergy accordingly was also investigated within the scope of this dissertation. The research is organised into three corresponding sections, each containing three projects. In the first section, a conceptual energy delivery framework was proposed, upon which the feasibility of using human body exergy model was investigated and a new analytical human body exergy model proposed. Varying certain inputs to the model, such as the relative humidity and the mean radiant temperature, can cause the results of the human body exergy model to vary significantly. Unlike relative humidity, mean radiant temperature is more challenging to measure and model. This radiant connection between the occupants and their surroundings is the focus of the second section. Beginning with a critique on the spatial limitations of conventional measurement techniques of mean radiant temperature, a comprehensive review of the complexity and challenges of modeling and measuring mean radiant temperature is presented. Its coupled relationship with air temperature was also investigated in a subsequent project. Finally, the third section begins by tracing back to the thermal sources such as geothermal for optimal temperatures. It then attempts to rearrange the energy delivery system by matching the supply and demand of energy concerning not only their amounts but usabilities - or exergy - to create a flow model from source to comfort.
