This book was released on 1997 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cette étude apporte une contribution à la validation et au développement d'un modèle de simulation thermo-aéraulique de bâtiment multizone en climatisation passive et active. L'ensemble des supports utilisés pour mener à bien ce travail de validation est décrit dans le premier chapitre. Après une brève description du code de calcul, nous présentons les deux supports expérimentaux qui ont servi pour nos campagnes de mesure, ainsi que l'ensemble de la chaîne d'acquisition. Le premier support est une maison en site réel, le deuxième est une cellule expérimentale équipée d'un climatiseur individuel et localisée à l'Université de la Réunion. Les expérimentations se sont toutes déroulées en environnement naturel et en climat tropical humide. Nous abordons ensuite dans un deuxième chapitre la méthodologie de validation que nous avons mise en place et qui s'inscrit dans une démarche d'uniformisation au niveau des équipes de recherche internationales. La méthode reposant sur l'utilisation d'outils d'analyse de signaux pour mettre en évidence une erreur de modélisation, est appliquée pour la validation des deux modèles d'enveloppe préalablement cités en environnement naturel. Le troisième chapitre s'attache à l'étude du couplage système/enveloppe, au développement et à l'intégration de modèles adaptés au code de calcul existant Codyrun. Plusieurs modèles de systèmes de traitement d'air sont proposés à différents niveaux de finesse, et pour des pas de temps différents. Une comparaison des modèles avec l'expérience apporte les premiers éléments de réponse quant à l'utilisation et à la précision de modèles horaires pour la modélisation des systèmes. La finalité d'un outil de conception et de recherche tel que le nôtre est d'aider le concepteur à réaliser un bâtiment le plus performant possible. Le chapitre quatre présente l'application du logiciel sur l'amélioration des performances thermiques des logements dans les départements d'outremer dans le cadre d'un label thermique Ecodom. Des simulations portant sur des logements types ont ainsi permis de mettre en place un certain nombre de prescriptions portant à la fois sur les composants architecturaux (toiture, parois opaques, baies vitrées) et sur la ventilation naturelle.

Download or read book Contribution à la validation globale d'un logiciel de simulation thermo-aéraulique du bâtiment written by Thierry Alex Mara and published by . This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Les logiciels de simulation du comportement thermique jouent un rôle capital dans l'amélioration des performances énergétiques des bâtiments. Se pose cependant le problème du crédit à apporter aux résultats de simulations de ces logiciels, autrement dit, de l'aptitude de ces derniers et des modèles intégrés à représenter la réalité. Dans ces travaux, nous appliquons une méthodologie basée sur la vérification du logiciel et sur la validation expérimentale de modèles. Pour mener à bien la première phase, nous appliquons une procédure qui a fait ses preuves : la procédure de comparaison inter-logiciels BESTEST. La validation expérimentale nécessite d'une part, la recherche des sollicitations mal prises en compte par le modèle et d'autre part, l'identification des paramètres les plus influents de ce derniers. Nous proposons, pour la première étude, l'utilisation d'un outil d'analyse temps-fréquence : la transformée de Fourier à court-terme. En ce qui concerne la seconde, une méthode d'analyse de sensibilité paramétrique de modèles, basée sur les outils d'analyse spectrale, a été développée. Cette technique constituant le coeur de ces travaux, un chapitre entier est dédié à l'analyse de sensibilité.

Book Synopsis Net-Positive Design and Sustainable Urban Development by : Janis Birkeland
Download or read book Net-Positive Design and Sustainable Urban Development written by Janis Birkeland and published by . This book was released on 2020-02-21 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: 'Sustainable' urban planning, policy and design professes to solve sustainability problems, but often depletes and degrades ever more resources and ecosystems and concentrates wealth and concretize social disparities. Positive Development theory holds that development could create more net ecological and social gains than no construction at all. It explains how existing conceptual, physical and institutional structures are inherently biased against the preservation and expansion of social and natural life-support systems, and proposes explicit reforms to planning, design and decision making that would enable development to increase future options and social and natural life-support systems - in absolute terms. Net-Positive Design and Sustainable Urban Development is aimed at students, academics, professionals and sustainability advocates who wonder why existing approaches have been ineffective. It explains how to reform the anti-ecological biases in our current frameworks of environmental governance, planning, decision making and design - and suggests how to make these changes. Cities can increase both the 'public estate' (reduce social stratification, inequity and other causes of conflict, increase environmental quality, wellbeing and access to basic needs, etc.); and the 'ecological base' (sequester more carbon and produce more energy than used during construction and operation, increase ecological space to support ecological carrying capacity, ecosystem functions and services, restore the bioregions and wilderness, etc.). No small task, this new book provides academic theory and professional tools for saving the planet, including a free computer app for net-positive design.
Book Synopsis Office Buildings by : Pranab Kumar Nag
Download or read book Office Buildings written by Pranab Kumar Nag and published by Springer. This book was released on 2018-12-31 with total page 533 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together concepts from the building, environmental, behavioural and health sciences to provide an interdisciplinary understanding of office and workplace design. Today, with changes in the world of work and the relentless surge in technology, offices have emerged as the repositories of organizational symbolism, denoted by the spatial design of offices, physical settings and the built environment (architecture, urban locale). Drawing on Euclidian geometry that quantifies space as the distance between two or more points, a body of knowledge on office buildings, the concept of office and office space, and the interrelationships of spatial and behavioural attributes in office design are elucidated. Building and office work-related illnesses, namely sick building syndrome and ailments arising from the indoor environment, and the menace of musculoskeletal disorders are the alarming manifestations that critically affect employee satisfaction, morale and work outcomes. With a focus on office ergonomics, the book brings the discussion on the fundamentals of work design, with emphasis on computer workstation users. Strategic guidance of lighting systems and visual performance in workplaces are directed for better application of ergonomics and improvement in office indoor environment. It discusses the profiles of bioclimatic, indoor air quality, ventilation intervention, lighting and acoustic characteristics in office buildings. Emphasis has been given to the energy performance of buildings, and contemporary perspectives of building sustainability, such as green office building assessment schemes, and national and international building-related standards and codes. Intended for students and professionals from ergonomics, architecture, interior design, as well as construction engineers, health care professionals, and office planners, the book brings a unified overview of the health, safety and environment issues associated with the design of office buildings.

Book Synopsis Daylight Glare in Offices by : Jan Wienold
Download or read book Daylight Glare in Offices written by Jan Wienold and published by . This book was released on 2010 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: The influence of discomfort glare is often underestimated in daylighting design and in the use of buildings. Many façade solutions are intended to increase the amount of daylight penetrating the room and creating a glare free environment at the same time. But as soon as a planning process comes to the point to quantify the glare freeness of a solution, the question of suitable glare measure arises. To analyze the reliability of existing glare rating methods, user assessments under real daylight conditions in office like test rooms are designed and carried out at two sites using different Venetian blinds and a foil system. For the evaluation of high dynamic digital images, a new tool "evalglare" is developed. The existing glare rating models show moderate or poor correlations with the user's perception of glare. The window luminance as single glare descriptor exhibits no correlation at all. On the basis of the user assessments a new daylight glare rating - the daylight glare probability DGP - is developed and validated. The DGP describes the probability that a person is disturbed by daylight glare. The DGP is also used as a basic glare descriptor for new climate based glare evaluation methods, which enables an assessment of daylight glare for a full year data set within a design process. For the evaluation, a glare rating classification based on simulations and frequency distributions is proposed.
