GAME-THEORETIC DESIGN FOR ENERGY-EFFICIENT BEHAVIORS IN RESIDENTIAL COMMUNITIES

Vanessa Kwarteng (16632588) 25 July 2023 (has links)
<p>    </p> <p>Technological advances and gaming have assisted users in becoming energy-efficient or raising awareness about energy efficiency. However, these games typically take place in schools and workplaces. Low-income households, which spend a larger percentage of income on utilities compared to average income households, exhibit greater sensitivity to energy disturbances. Despite this, there has been limited research on applying these technologies in low-income households. </p> <p><br></p> <p>The dissertation addresses the research gap concerning motivating low-income households to adopt new technologies focused on implementing energy-efficient HVAC behaviors. To achieve this objective, a gamification approach is employed, integrating a competitive social game into a cloud-based application named MySmartE. This application offers personalized eco-feedback and enables voice commands using Amazon Alexa. The game is deployed in two multi-residential low-income household communities located in Indiana. The collected data from field studies is analyzed to explore various aspects, including community interactions during the gaming seasons, technology adoption, and factors influencing participation in the social game. The findings reveal a positive correlation between increased gaming interac- tions and the adoption of MySmartE technology within these communities, underscoring the potential of gamification and technology to effectively engage low-income households in adopting energy-efficient practices. </p>

<b>USE OF ENERGY MONITORING TO EVALUATE INDOOR ENVIRONMENTAL QUALITY IN RESIDENTIAL BUILDINGS</b>

Hongbo Lu (18419346) 22 April 2024 (has links)
<p dir="ltr">As the urbanization trend prevails worldwide, more people are moving to major metropolitan areas, causing housing resources to be in urgent demand. Tiny homes, designed to offer a minimalist lifestyle while also addressing growing housing needs, have become increasingly popular among home seekers. Since the COVID-19 outbreak, individuals primarily spend their time indoors, and with more people adopting work-from-home lifestyles, ensuring a high-quality, sterile, and comfortable indoor environment becomes crucial for indoor occupants. Many studies have highlighted that the activities of occupants significantly influence indoor environmental quality (IEQ) and energy consumption in buildings and applying disinfectants will generate increasing amount of volatile organic compounds (VOCs) which occupants could inhale, causing adverse health effects. Within this thesis, two studies are introduced and discussed. The first study, namely “zEDGE Living Experiments,” conducts a comprehensive evaluation of IEQ satisfaction and energy usage in the Purdue zEDGE Tiny House through real-time measurement and survey analysis. Twenty full-scale experiments were conducted during the winter season. The study first evaluates participants’ perception of IEQ factors, with thermal comfort and indoor air quality (IAQ) emerging as top priorities. It then examined energy adaptive behavior to understand maintenance of comfortable indoor conditions, noting primary adaptive strategies including heating, ventilation, and artificial lighting. The study then measured IEQ and energy consumption, evaluating occupants’ IEQ satisfaction levels. The average energy use was recorded at 10.3 kWh, with occupants generally satisfied with IEQ in the zEDGE Tiny House. Analysis indicated that heating and cooking were significant energy consumers, potentially exposing occupants to high indoor air pollutant levels in such compact living spaces. The second campaign, namely “Performance Evaluation of PID and PTR-TOF-MS,” compares the VOC detection abilities of photoionization detectors (PID) and a state-of-the-art proton-transfer-reaction time-of-flight mass spectrometer (PTR-TOF-MS). 54 controlled emission experiments were carried out among 18 different disinfectant products with main ingredients based on alcohol, lactic acid, peracetic acid/acetic acid, and botanical products. The results from time-series and correlation analyses indicate that the PID and PTR-TOF-MS were able to detect VOC signals from emission experiments. While the performances of the PID and PTR-TOF-MS were similar under experiments with alcohol-based products, the PID performed less well with products based on lactic acid and botanical products, and unsatisfactory for peracetic acid/acetic acid-based products.</p>

Discours, intertextualite et altérité dans "Pourquoi as-tu laissé le cheval à sa solitude ?" de Mahmoud Darwich / Discourse, intertextuality and otherness in "Why did you leave the horse alone" of Mahmoud Darwich

Amayra, Mahmoud 03 July 2019 (has links)
Cette étude porte sur l’analyse du discours identitaire du recueil Pourquoi as-tu laissé le cheval à sa solitude ? de Mahmoud Darwich à savoir la nature de la relation que le Moi (celui de Mahmoud Darwich) entretient avec le Moi de l’Autre. Autrement dit, le recueil en question ressemble à un dialogue où le même et l’autre se plongent dans un discours à titre argumentatif. La réponse à la question de la relation entre les deux parties du dialogue est abordée, premièrement, d’un point de vue thématique/théorique : la présentation de la figure emblématique du Moi darwichien perçu en tant qu’un, ayant une identité personnelle, culturelle, sociale et nationale, différente de celle dont dispose l’autre un (celui de l’Autre). Deuxièmement, d’un point de vue pratique, le type de relation entre les deux côtés a été montré à travers l’analyse du corpus du recueil se composant de six groupes. / This study focuses on the analysis of identity discourse of Darwich’s collection : Why did you leave the horse alone? in order to know the nature of relationship that the me of Darwich maintains with the me of the Other. In other words, our collection looks like a “dialogue” where the me of Darwich and the me of the Other plunge into an argumentative discourse. To answer our question about the relationship between the two parts of dialogue, we have firstly chosen a theoretical approach: the presentation of the emblematic figure of Darwich perceived as one, having a personal, cultural, social and national identity, different from the identity of the other one. Secondly, through a practical point of view, the type of relationship between the two sides has been shown through the analysis of the corpus consisting of six groups.

Improving predictions of operational energy performance through better estimates of small power consumption

Kossmann de Menezes, Anna Carolina January 2013 (has links)
This Engineering Doctorate aims to understand the factors that generate variability in small power consumption in commercial office buildings in order to generate more representative, building specific estimates of energy consumption. Current energy modelling practices in England are heavily focussed on simplified calculations for compliance with Building Regulations, which exclude numerous sources of energy use such as small power. When considered, estimates of small power consumption are often based on historic benchmarks, which fail to capture the significant variability of this end-use, as well as the dynamic nature of office environments. Six interrelated studies are presented in this thesis resulting in three contributions to existing theory and practice. The first contribution consists of new monitored data of energy consumption and power demand profiles for individual small power equipment in use in contemporary office buildings. These were used to inform a critical review of existing benchmarks widely used by designers in the UK. In addition, monthly and annual small power consumption data for different tenants occupying similar buildings demonstrated variations of up to 73%. The second contribution consists of a cross-disciplinary investigation into the factors influencing small power consumption. A study based on the Theory of Planned Behaviour demonstrated that perceived behavioural control may account for 17% of the variation in electricity use by different tenants. A subsequent monitoring study at the equipment level identified that user attitudes and actions may have a greater impact on variations in energy consumption than job requirements or computer specification alone. The third contribution consists of two predictive models for estimating small power demand and energy consumption in office buildings. Outputs from both models were validated and demonstrated a good correlation between predictions and monitored data. This research also led to the development and publication of industry guidance on how to stimate operational energy use at the design stage.

Arquitetura possível: os espaços comuns na habitação de interesse social em São Paulo / Possible architecture: common spaces in social housing in São Paulo

Navazinas, Vladimir 09 May 2007 (has links)
Esta dissertação trata a questão dos espaços comuns em alguns empreendimentos de habitação de interesse social em São Paulo. Resgata historicamente as diversas manifestações, nas cidades, de espaços comuns próprios de construções residenciais e de conjuntos habitacionais. Com estudos de caso específicos, recupera quatro experiências dos primeiros programas de construção de moradias por mutirão e autogestão realizados em São Paulo, entre os anos 1989 e 2004, em razão de suas peculiaridades e qualidades que os tornaram bons modelos de projetos de arquitetura habitacional de interesse social. Procura, a partir da análise das condicionantes dos projetos de arquitetura e urbanismo, avaliar como os espaços comuns são geridos, como foram apropriados pelos moradores, e em que medida tal apropriação se relaciona ou não com os usos pensados e propostos (ou não) nos projetos originais. / This dissertation covers the matter of communal areas in some public-funded housing projects in São Paulo. It recalls the historical and varied advent, throughout cities, of such communal areas that are usual to residential and housing project construction. Using studies of specific cases, this research analyzes four experiences from the first public occupant-run housing project construction programs carried out in São Paulo, between 1989 and 2004. They were selected because of the peculiarities and features that made them such good models for public-funded architectural housing projects. The aim is to assess, by analyzing the conditioning factors of the architectural and urbanization projects, how the communal areas were put together, how they were utilized by the occupants, and how such utilization is related, or not, to the possibilities previously planned or proposed in the original projects.

Determinants of Usage of Age-Appropriate Child Safety Seats in Connecticut

Violano, Giuseppina Mendillo 01 January 2015 (has links)
In the United States, motor vehicle crashes are one of the leading causes of unintentional injury death and disability for children ages 1'15 years. Despite local, state, and federal legislative and educational efforts, children continue to be restrained improperly and thus face harm. Identifying behaviors and barriers that place child occupants at risk is crucial for implementing focused, injury-prevention programs and policies. The purpose of this study was to evaluate the effectiveness of Connecticut's child passenger safety law that was strengthened in 2005. This study involved a multifactorial approach to predicting child seat use, guided by Roger's diffusion of innovations as the theoretical framework. The analysis determined if there was a difference in the prevalence of car seat use before as compared to after law implementation and identified variables that best predicted the use of car seats and premature transition to a seat belt. Using Connecticut's Crash Data Repository, a logistic regression analysis indicated that car seat use was 1.3 times more likely post law (OR 0.75; 95% CI: 0.65-0.86) and that in particular, children ages 4, 5, and 6 (combined) were most positively affected by the law (OR 0.67; 95% CI 0.54-0.82). Driver sex, crash time of day, child age, and child seating position were all determined to be significant predictors of whether or not a child was in a child safety seat. Additionally, these variables were also determined to be predictors of early transition to use of a lap/shoulder belt (versus child seat). The social change implication of this study is that identifying predictors of car seat use and early transition helps to formulate and implement injury prevention measures that could in turn help to decrease medical costs, save lives, and prevent injuries.
