Mapeamento da biótopos: instrumento para o fomento da qualidade ambiental / Biotopes mapping: instrument for promotion of ambient quality

Marcos Antônio de Melo 10 December 2009 (has links)
O mapeamento de biótopos pode ser considerado como uma ação prática do planejamento da paisagem. O método surgiu para conduzir a análise e o entendimento das características estruturais e funcionais da paisagem, demonstrando identidades ecológicas entre porções territoriais mediante o estudo/diagnóstico dos componentes biofísicos, antrópicos e das inter-relações existentes. Além do estabelecimento de indicativos, qualitativos e quantitativos que denotem e mensurem parâmetros de qualidade ambiental. Destarte, a realização deste mapeamento visa o estabelecimento de bases para o planejamento territorial, tendo a mensuração da qualidade ambiental como elemento primordial para sua efetivação, justificando assim, a aplicabilidade da referida metodologia, inspirada em experiências européias, onde tais mapeamentos são realizados em escalas de detalhe. O referencial teórico adotado parte de uma abordagem geossistêmica, onde a paisagem pode ser representada por um conjunto de biótopos, denotando a integração de variáveis naturais e antrópicas, configuradas em unidades homogêneas. Os procedimentos teóricos e operacionais atendem a variadas etapas, constituídas em trabalhos de levantamentos de campo, sistematização de dados, caracterização e mapeamentos. Os resultados obtidos, segundo preceitos teóricos, metodológicos e procedimentos propostos, foram organizados em forma de dados alfanuméricos e espaciais, inseridos em banco de dados com interfaces com SIGs. Assim, foram geradas cartas temáticas em escalas de detalhe (1:10000) cartografando e correlacionando as informações produzidas, traduzidas em parâmetros de qualidade ambiental, com destaque para a cobertura vegetal. / Mapping biotopes can be considering an action of the Landscape Planning in order to guide the analysis and understanding of the structural and functional characteristics of the landscape. As a method, Biotope Mapping demonstrates ecological identities among territorial parts through studies/diagnoses of biophysics and humans components, and their relationships. Moreover it measures and establishes quality and quantitative indexes which demonstrated parameters of Environmental Quality. This paper intended apply the Biotope Mapping methodology in order to establish bases to a territorial planning, considering the Environmental Quality as a primordial element to effective it as well and to justify the methodology application was inspired in Europeans experiences that Biotope Mapping is made in scale of details. The bibliographic references came from a geosystemic approach and intended to make up natural and human variables in homogeny units. The adopted theorical and operational procedures were organized in steps which were preliminary and field works, data systematization, characterization and mappings. According all of theorical and methodological precepts and practical procedures proposals, the obtained results were organized in alphanumerical and spatial information. They were inputted in a database with GISs interface, and in a scale of details (1:10000) the thematic charts were created in order to cartographing this created information, measure and Environmental Quality indexes, with eminence for cover vegetable.

Cenário ambiental da Bacia Hidrográfica do Arroio Grande a partir das diatomáceas epíliticas e fatores abióticos / Environmental setting of arroio grande hydrographical basin from epilithic diatoms and abiotic factors

Silva, Juliana Ferreira da 26 February 2014 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Activities carried on around aquatic systems are reflected in the water quality of these environments as well as in their biotic communities. Epilithic diatomsare known effective bioindicators.This study aimed to assess the environmental situation of the Arroio Grande Hydrographical Basin, RS, Brazil, situated in agricultural land and away from urban occupation. Monthly samplings of water and epilithic diatoms were carried out from October 2012 to March 2013 in thirteen sampling points. Permanent slides for the analysis of diatom communities were mounted andat least 600 valves per slide were counted to estimate the relative abundance. Taxa were identified to species level. Dissolved oxygen, conductivity, turbidity and water temperature were measured on site while pH, biochemical oxygen demand, alkalinity, hardness, nitrate, nitrite, phosphate and pesticides were analysed in the laboratory. 110 taxa belonging to 22 families and 39 genera were identified.The most representative families were Sellaphoraceae (20) followed by Naviculaceae (15) and Cymbellaceae (12). The sampling sites with higher species richness were the points on the west side of the basin. The richest genera were GomphonemaEhrenberg, Sellaphora Mereschkowskyand Navicula Bory. Diatom relative abundance and abiotic variables results were analysed by multivariate ordination and Anosim. The greatest variation was found among sampling months and a spatial gradient has not been identified.Althought water quality in the area was found to be good, the diatom community has responded to the various agricultural activities carried out along the sampling period. / As atividades exercidas no entorno de ambientes aquáticos são refletidas na qualidade da água desses ambientes assim como nas comunidades que os habitam. As diatomáceas epiliticas desempenham satisfatoriamente esse papel bioindicador. Diante disso, o presente trabalho teve como objetivo avaliar a situação ambiental da Bacia Hidrográfica do Arroio Grande, RS, Brasil, uma bacia de área predominentemente agrícola. Amostragens mensais de água e diatomáceas epilíticas foram realizadas de outubro de 2012 a março de 2013 em treze pontos amostrais. Foram confeccionadas lâminas permanentes para a análise das comunidades de diatomáceas, com contagem de no mínimo 600 valvas por lâmina para estimativa da abundância relativa e identificação das espécies presentes. Oxigênio dissolvido, condutividade elétrica, turbidez e temperatura da água foram medidos no local enquanto o pH, demanda química de oxigênio, alcalinidade, dureza, nitrato, nitrito, fosfato e agroquímicos em laboratório. Foram identificados 110 táxons pertencentes a 22 famílias e 39 gêneros e 77 táxons abundantes.As famílias mais representativas foram Sellaphoraceae (20) seguida porNaviculaceae (15) e Cymbellaceae (12). Os pontos amostrais com maior riqueza específica foram os pontos situados do lado oeste da bacia. Os gêneros mais ricos em espécies foram Gomphonema Ehrenberg, Sellaphora Mereschkowskye Navicula Bory.As análises de ordenamento e a ANOSIM revelaram uma estruturação ambiental principalmente por mês de coleta, sendo que um gradiente espacial não foi identificado. A situação ambiental da Bacia Hidrográfica do Arroio Grande a partir dos fatores abióticos e bióticos não se mostrou degradada pelas atividades exercidas ao seu entorno, porém mesmo em curto prazo pode-se observar uma resposta das comunidades as atividades exercidas.

Producing and consuming artisan food: a way of preserving our biological heritage? : A phenomenographic study on how biological heritage is understood, described and communicated in the context of artisan food production and consumption

Girard, Chloé January 2017 (has links)
In Sweden, the environmental quality goal 13 for A Varied Agricultural Landscape, that combines environment, food production and rurality and aims at keeping the agricultural landscape open, was considered as not achieved in 2016. One of the reasons for this non-achievementis the agricultural intensification and specialisation and in turn the decrease in number of pastures during the 20th century, threating thus habitats, diversity and values resulting from a continuous, traditional use of the land commonly called ‘biological heritage’. This study focuses on the traditional and sustainable animal husbandry using pastures, contributing to both the preservation of biological heritage and the production of high-quality food. It relies upon the assumption that the link between artisan food production and biological heritage is not well understood nor highlighted by the different actors taking part into the process of producing, selling, buying and consuming artisan food products in the rural areas of mid-northern Scandinavia, and therefore the study attempts to contribute with knowledge about how biological heritage is understood, described and communicated within this context. For such purposes the study takes a phenomenographic approach with biological heritage, pastures and artisan food products as the conceptions to be tested, and consists of semi-structured interviews of three agencies and surveys of artisan food producers and consumers. It adopts an environmental communication theoretical framework where a model is suggested for investigating actors’ learning process of biological heritage, from agencies to producers to consumers. The results reveal three phenomenographic categories showing that agencies and producers understand biological heritage in terms of (1) cared habitat and cared species, (2) historical and cultural know-how and (3) animals and their tasteful diet, and it is showed that the necessity of a continuous, traditional human use was less put forward than the cultural dimension of biological heritage. Also producers communicate about biological heritage to consumers through both their products and their actions. Furthermore the results show that consumers’ understandings of biological heritage are similar to the agencies’ and producers’ phenomenographic categories and that they could make a link between artisan food production and biological heritage, but only to some extent. Finally, in order to create an economic value for such products, a sense of place for pastures is argued to be a basis for people’s willingness to take care of and safeguard pastures. This study can be the starting point for further research, especially for investigating how producers actually interact with consumers about biological heritage when selling their products.

The Effects of Classroom Environmental Quality on the Early Literacy Outcomes of a Regionally Heterogeneous Population of Latino Children

Marin, Maria M 25 March 2010 (has links)
The purpose of this study was to examine the relation between classroom environmental quality and early literacy outcomes amongst a sample of Latino children from various Latin-American countries. Participants included 116 preschoolers that attended various childcare centers in Southeast Florida. Participant’s literacy knowledge was assessed using the Test of Preschool Early Literacy. Classrooms were assessed on environmental quality using the Early Childhood Environmental Rating Scale-Revised. A regression analysis revealed that classroom environmental quality did not account for Latino children’s early literacy outcomes. However, a multiple regression analysis was significant (R2= .15, F(5, 115) = 3.86, p< .05) indicating that quality has a varying impact on children’s early literacy skills based on children’s region of origin. Findings suggest that high classroom environmental quality does not necessarily mean better literacy development for Latino children. Additionally, Latino children should not be viewed as a homogeneous group, particularly in relation to their development of literacy skills in English.

Fatores como ventilação, temperatura, iluminação, forma e volume devem ser trabalhados de maneira a propiciar ambientes adequados que promovam uma qualidade de vida desejável. Devido à percepção ambiental ser derivada do processamento do estímulo sensorial, é premissa desta tese de doutorado que o ritmo biológico e o estado psicológico dos usuários são diretamente influenciados pelas variáveis espaciais. Assim, a hipótese da pesquisa é que os ambientes hospitalares, controlados exclusivamente por sistemas artificiais de iluminação e controle de temperatura e associados ao intenso ritmo de trabalho, alteram o ritmo biológico dos médicos residentes ampliando a ocorrência de doenças psicológicas e potencializando as chances de erro de diagnóstico. O objetivo é identificar como o ambiente hospitalar em condições artificiais, especialmente de iluminação e temperatura, afetam a qualidade de vida e a percepção dos médicos residentes por meio da análise de variáveis fisiológicas e psicológicas. Para tanto, foram feitas avaliações sobre as variáveis do ambiente: i. quantitativa aferindo a temperatura, iluminação, umidade relativa, velocidade do ar e aspectos físicos; e ii. qualitativa com questionários de percepção visual, térmica, acústica e de uso do espaço. Os aspectos psicofisiológicos dos médicos residentes foram avaliados segundo: i. variável emocional com instrumentais validados no Brasil para delimitação da ansiedade, depressão, estresse e transtorno psiquiátrico no ambiente de trabalho, além do sono e sua qualidade e ii. variável hormonal mediante coleta salivar e uso do Teste ELISA para dosagem de cortisol e melatonina. A pesquisa é caracterizada como exploratória e transversal prospectiva devido às variáveis de desfecho observadas e segue o delineamento da pesquisa experimental. O estudo foi realizado em condições reais de uso no Setor da Imaginologia do Hospital de Clínicas da UNICAMP/Campinas. Dentre os resultados obtidos foram constatadas, dentre outros, respostas psicofisiológicas diferenciadas de acordo com as condições ambientais e o nível de residência médica; também se verificou que estas mesmas condições não alcançaram valores capazes de interferir integralmente na saúde psicofisiológica dos médicos residentes independente do nível. Esta pesquisa além de contribuir com a extensão do estado-da-arte, acrescentou informações à coleção de dados sobre a influência do ambiente sob condições artificiais de seus sistemas ambientais na percepção e saúde psicofisiológica de uma parcela da população hospitalar, auxiliando no desenvolvimento de melhorias na qualidade do ambiente daquela tipologia arquitetônica / Abstract: The quality of the built environment involves spatial characteristics that affect the perception and the behaviour of its users. Factors such as ventilation, temperature, lighting, shape and volume must be worked out in order to provide appropriate environments that promote a good quality of life. Because environmental perception is derived from the processing of sensory stimulus, the premise of this doctorate thesis is that the biological rhythm and the psychological state of users are directly influenced by spatial variables. Thus, the hypothesis of the research is that the hospital environment, controlled exclusively by artificial lighting and climate control, and associated to the intense pace of work, alter the biological rhythm of resident physicians increasing the occurrence of psychological diseases and increasing the chances of them making diagnostic errors. The goal is to identify how the hospital environment under artificial conditions, especially lighting and temperature, affect the quality of life and the perception of medical residents through the analysis of physiological and psychological variables. Therefore, the evaluated environmental variables were; i. quantitative gauging of the temperature, lighting, relative humidity, air velocity and physical aspects; ii. qualitative questionnaires regarding visual perception, thermal, acoustic and use of space. Psycho-physiological aspects of resident physicians were evaluated according to; i. emotional variables with validated instruments in Brazil for the demarcation of anxiety, depression, stress and psychiatric disorder in the workplace, in addition to sleep and its quality; ii. hormonal variables by saliva collection and the use of ELISA test for cortisol and melatonin dosage. The research is characterized as exploratory and prospective due to the observed outcome variables and follows the design of experimental research. The study was conducted in real conditions in the Radiology Department of the Hospital at UNICAMP/Campinas. Among the results found with resident doctors were different psycho-physiological responses according to the environmental conditions; also that these same conditions did not reach values able to fully interfere in the psycho-physiological health of physicians whatever the year of residency. This research contributes to the advance of the state of the art, adding information to the data already collected on the influence of artificial environmental conditions on the perception and psycho-physiological health of a proportion of the hospital population, contributing to the development of the quality of the environment through architectural design / Doutorado / Arquitetura, Tecnologia e Cidade / Doutora em Arquitetura, Tecnologia e Cidade

A partir deste contexto, justifica-se a necessidade de se estudar os problemas ambientais nestas áreas, através de uma análise da qualidade ambiental. Análises como estas podem identificar o desequilíbrio entre a sociedade e os recursos naturais, através da caracterização das pressões geradas por fluxos econômicos e humanos. Identifica-se que em Juiz de Fora/MG há algumas áreas em estado de desequilíbrio. A área de estudo da presente pesquisa, a Bacia do Córrego Matirumbide, localizada na zona leste da cidade, caracteriza-se pela presença de expressivo adensamento urbano em áreas de encosta e pouca presença de cobertura vegetal arbórea, além de ser uma área reconhecida por problemas voltados à ocupação inadequada e os recorrentes casos de escorregamentos, principalmente em períodos de maiores níveis de precipitação. Assim, através de visitas a campo, além da utilização de dados secundários, elaborou-se uma série de planos de informação em ambiente SIG que puderam representar os atributos negativos característicos desta bacia: a baixa densidade de cobertura vegetal arbórea, a falta de espaços livres de edificações, a alta densidade populacional, a baixa densidade de renda, e o alto risco a ocorrência de escorregamentos. Estes planos de informação foram sobrepostos de acordo com a metodologia de análise de Qualidade Ambiental proposta por Nucci (1998), pautado na Ecologia da Paisagem e no Planejamento da Paisagem, para que se pudesse chegar ao objetivo central. A inserção do atributo negativo representado pelo risco a ocorrência de escorregamentos, até então, não tinha sido utilizado em pesquisas sobre Qualidade Ambiental. Desta forma, buscou-se a sua análise pela manipulação da modelagem matemática, através do modelo probabilístico SINMAP, no qual viabilizou a representação e criação deste plano de informação para a pesquisa. Identificou-se que a bacia do Córrego Matirumbide é expressivamente urbanizada, com baixa densidade de cobertura vegetal arbórea, além de poucos espaços livres de edificações. Caracterizou-se também a alta densidade populacional relacionada à baixa densidade de renda, encontradas principalmente nas áreas com maiores valores de instabilidade a ocorrência de escorregamentos, indicando estas áreas com alto risco a ocorrência destes eventos. As regiões urbanas onde mostraram pior Qualidade Ambiental foram as regiões Nossa Senhora Aparecida e Santa Rita, com a presença de até cinco atributos negativos; já as regiões urbanas que mostraram melhor Qualidade Ambiental foram as regiões Bairu e Vale dos Bandeirantes. Concluiu-se que, para a área de estudo, a relação negativa entre a densidade populacional e a densidade de renda juntamente à ocupação inadequada em áreas de encosta (identificadas com alta instabilidade), foi a que apresentou uma condição mais desfavorável à qualidade do ambiente. / Nowadays in urbanized areas, it is possible to see that the perspective provided by the low quality of the environment is a reflection of a historical situation of unsustainability of cities at all levels of social participation. From this context, justifies the need to study environmental problems in these areas, through an analysis of environmental quality. Analyses such as these can identify the imbalance between society and natural resources, through the characterization of pressures generated by economic and human flows. We find that in Juiz de Fora / MG there are some areas in a state of imbalance. The study area of this research, Watershed of Matirumbide Stream, located on the east side of the city is characterized by the presence of significant urban density in areas of low slope and presence of woody vegetation cover, as well as being an area recognized by problems focused on inadequate occupation and recurrent cases of landslides, especially in periods of higher rainfall. Thus, through field visits, besides the use of secondary data, we prepared a series of coverages in a GIS environment that might represent the characteristic negative attributes of this basin: the low density of woody vegetation cover, lack of open spaces of buildings, high population density, low density of income and high risk to the occurrence of landslides. These coverages were overlaid according to analysis Environmental Quality methodology proposed by Nucci (1998), based on Landscape Ecology and Landscape Planning, so that it could reach the main goal. The insertion of the negative attribute represented by the occurrence of landslide risk, until then, had not been used in research on Environmental Quality. Thus, we sought its analysis by manipulation of mathematical modeling, through the probabilistic model SINMAP, which enabled the creation of this representation and information for the research plan. It was found that the Watershed of Matirumbide Stream is significantly urbanized, with low density of woody vegetation cover, plus a few free spaces of buildings. Also characterized the high population density related to the low density of income, mainly found in areas with higher instability occurrence of landslides, indicating these areas at high risk to the occurrence of these events. Urban regions which showed worse Environmental Quality were the regions Nossa Senhora Aparecida and Santa Rita, attended by up to five negative attributes; urban areas have shown that were the best Environmental Quality were Bairu and Vale dos Bandeirantes regions. It was concluded that the negative relationship between population density and density along with inadequate income occupancy in hillside areas (identified with high instability), showed the most adverse condition the quality of the environment.

Hållbara offentliga uterum : En studie om multifunktionsmoduler för Helsingborg drivna av Öresundskraft. / Sustainable common space : A study of multifunctional modules for Helsingborg powered by Öresundskraft

John, Julia January 2018 (has links)
Studien utfördes på uppdrag av Öresundskraft och handlar om nya offentliga biogasdrivna multifunktionsmoduler som kommer att placeras i Helsingborgs nya stadsdelar i H+ området. Arbetet utfördes delvis i Helsingborg där en enkät fördelades inom stadsdelarna som omfattar H+ området.  Syftet med studien har varit att utforska hur multifunktionsmodulerna borde utformas för att kunna främja de 16 svenska miljökvalitetsmålen, för att vara attraktiva och hållbara och för att kunna främja energibeteendet hos användare. Resultaten visar att det finns olika tolkningar kring vad som gör en offentlig plats attraktiv och hållbar. Slutsatsen är att utformningen av de nya offentliga uterummen borde kunna främja måluppföljningen av de svenska miljökvalitetsmålen, om designen stödjer de. Dock behöver multifunktionsmodulerna stödjas av resterande utformning av H+ området och H+ områdets miljöprofil, för att kunna bidra till det. / The study was conducted on behalf of Öresundskraft and is about new public biogas-driven multifunctional modules that will be located in Helsingborg's new districts in the H + area. The study was carried out in Helsingborg, where a survey was distributed within the areas that comprise the H + area. The purpose of the study has been to explore how the multifunctional modules should be designed to promote the 16 Swedish environmental quality objectives, to be attractive and sustainable, and to promote the energy behavior of users. The results show that there are different interpretations of what makes a public place attractive and sustainable. The conclusion is that the design of the new public space should be able to promote the goal to follow-up the Swedish environmental quality objectives, if the design supports them. However, the multifunction modules need to be supported by the remaining design of the H + area and the H + area's environmental profile, in order to contribute to it.

Qualidade ambiental nos espaços livres de áreas verticalizadas da cidade de São Paulo\". / Environmental quality in free spaces of verticalized areas of the city of São Paulo

Moreno, Manuel Francisco Navarro 27 March 2001 (has links)
Este trabalho versa sobre a verticalização em São Paulo e seus impactos sobre a qualidade ambiental dos espaços livres. Parte-se do pressuposto de que a não compreensão, por parte do corpo técnico e da população em geral, dos problemas resultantes da verticalização (tais como: sombreamentos, canalização de ventos, alteração da umidade do ar, maior aquecimento e agravamento da poluição) piora a qualidade ambiental dos espaços livres. No corpo do trabalho são introduzidos os procedimentos básicos para o aprimoramento da qualidade ambiental, que devem ser conhecidos e aplicados normalmente no projeto dos espaços livres. Os espaços livres públicos, como as vias, praças e parques, assim como os espaços privados, que são os espaços livres existentes nos lotes, em torno das edificações; têm perdido sua habitabilidade em conseqüência da verticalização e do adensamento urbano, mesmo com a aplicação da atual legislação de uso e ocupação do solo. Implantada em 1972, ela gera espaços livres mais generosos do que anteriormente, com a obrigatoriedade de novos recuos e menores taxas de ocupação. Esta legislação ao determinar espaços livres um pouco maiores, cria condições para que os incorporadores agreguem, aos seus empreendimentos, equipamentos para o lazer, mesmo que essas áreas sejam ambientalmente inadequadas. A qualidade ambiental resultante é analisada sob o aspecto perceptivo-sensorial, considerando-se a influência que o Meio Urbano Verticalizado (malha viária, espaços livres, quadras, lotes e edificações) tem sobre as variáveis ambientais do Meio Natural (radiação solar, ar, água, solo, vegetação e fauna). As variáveis ambientais são analisadas em cinco regiões com bairros densamente verticalizados: a) Centro: Higienópolis; b) Norte: Freguesia do Ó; c) Sul: Moema; d) Leste: Vila Gomes Cardim; e) Oeste: Perdizes. Como resultado, são apresentadas recomendações, implementáveis no processo de projeto, para melhorar a qualidade ambiental nos espaços livres urbanos de áreas verticalizadas. / This thesis turns on the verticalization in São Paulo and its impacts on the environmental quality of free spaces. It breaks of the presupposition that the nonunderstanding, on the part of the technical body and of the population in general, of the resulting problems of the verticalization (such as shadows, canalization of winds, alteration of the humidity of the air, larger heating and worsening of the pollution) worsens the environmental quality of free spaces. In the body of the work the basic procedures are introduced to increase the environmental quality that should be known and usually applied in the project of such spaces. The public free spaces, as roads, squares and parks; as well as the private spaces, that are the existent free spaces in the lots, around the constructions; they have been losing its inhabitability in consequence of the verticalization and the increase of the urban areas, even with the application of the current legislation on use and occupation of the soil. Implanted in 1972, it generates more generous free spaces than previously, with the obligation of new recoils and smaller occupation rates. This legislation when establishing free spaces a little larger, it creates conditions so that the incorporators joins, to its enterprises, equipments for leisure, even if those areas are functionally inadequate for such, even if they never receive sun light or that make funnel-shaped and accelerate the winds. The resulting environmental quality is analyzed under the perceptive-sensorial aspect, considering the influence that the Verticalized Urban Way (its street ensemble, free spaces, blocks, lots and constructions) has on the environmental variables of the Natural Way (solar radiation, air, water, soil, vegetation and fauna). The analysis are applied to five areas with neighborhoods densely verticalized: a) Center: Higienópolis; b) North: Freguesia do Ó; c) South: Moema; d) East: Vila Gomes Cardim; e) West: Perdizes. As result, recommendations presented, to be used in the project process, to improve the environmental quality in the urban free spaces of verticalized areas.

<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>
