Analyse comparative de systèmes de construction industrialisés et leur applicabilité à une habitation multifamiliale verticale pour la classe moyenne à Recife (Brésil).

Depuis le début du XXe siècle, les architectes et ingénieurs anticipaient et idéalisaient l'industrialisation des bâtiments afin que les pièces des édifices puissent être conçues dans une usine de montage pour procéder ensuite à leur assemblage sur les chantiers. À l'heure actuelle, grâce à des chercheurs dédiés, cette industrialisation s’est concrétisée et de nombreux systèmes de construction industrialisés existent dans le monde entier, adaptés à des environnements particuliers. Dans ce contexte, cette étude a pour but d'analyser comparativement plusieurs systèmes à l’aide de certains critères d’évaluation, et de sélectionner, deux systèmes préfabriqués les mieux adaptés aux habitations multifamiliales verticales destinées à une population de classe moyenne aisée de la ville de Recife, au Brésil. La méthodologie s’inspire de l'approche systémique, utilisée par White (1970) et Richard (2002), les deux se caractérisant par une démarche évaluative. Ainsi avons-nous choisi comme étant les plus appropriés, parce que répondant bien au cadre général de Recife, le système préusiné en panneaux DESCON ainsi que celui de poutres et colonnes, commercialisé par les entreprises T&A et PDI, les deux en béton.

Design of maintenance structures for rural electrification with solar home systems. The case of the Moroccan program.

n decentralised rural electrification through solar home systems, private companies and promoting institutions are faced with the problem of deploying maintenance structures to operate and guarantee the service of the solar systems for long periods (ten years or more). The problems linked to decentralisation, such as the dispersion of dwellings, difficult access and maintenance needs, makes it an arduous task. This paper proposes an innovative design tool created ad hoc for photovoltaic rural electrification based on a real photovoltaic rural electrification program in Morocco as a special case study. The tool is developed from a mathematical model comprising a set of decision variables (location, transport, etc.) that must meet certain constraints and whose optimisation criterion is the minimum cost of the operation and maintenance activity assuming an established quality of service. The main output of the model is the overall cost of the maintenance structure. The best location for the local maintenance headquarters and warehouses in a given region is established, as are the number of maintenance technicians and vehicles required.

South Carolina Housing Trust Fund Emergency Repair Manual

The emergency repair activity under the South Carolina Housing Trust Fund program is designed to assist very low‐income homeowners in making needed and necessary repairs to their owner‐occupied homes to eliminate life, health and safety issues to the occupant. This document explains emergency repair activity guidelines, eligibility requirements for properties, rehabilitation construction guidelines and payments.

INDOOR MOLD After a Severe Weather Event

Many South Carolina residents are concerned about indoor mold after severe weather events. DHEC has compiled this informational handout with recommendations to guide decisions regarding mold in homes and workplaces.

Levantamento de Danos dos Azulejos da Capela de Nossa Senhora do Rosário do Mosteiro de São Bento de Cástris

The Chapel of Nossa Senhora do Rosário is located in the cloister of the São Bento de Cástris monastery and shows off a blue and white tile panel with 6 tiles of height, representing the scenes of the Life of the Virgin in five panels: Adoration of the Shepherds, Presentation of the Virgin in the Temple, Annunciation, Visitation and The Marriage of the Virgin. The authorship of this work is unknown and its date has not yet found consensus. The tiles are in poor condition and have been the target of repeated vandalism or attempted theft over time. During the Residência Cisterciense (Cistercian Residence), held in São Bento de Cástris in September 2013, it has been made a survey of the tile panel’s observable damages including graphic and photographic record of its condition.

Método LNEC para avaliação e classificação da qualidade acústica de edifícios habitacionais: ferramenta de estimação de custos médios de transição entre classes acústicas

O conforto acústico na habitação é essencial para permitir um repouso tranquilo e regenerativo. Este conforto é obtido principalmente pela redução do ruído e aumento do isolamento sonoro dos elementos de compartimentação. Para a qualificação deste conforto é necessário efetuar uma análise global do edifício, onde são considerados os fatores internos e externos à habitação, ou seja, considerando a acústica da envolvente (Vizinhança), do edifício (Edifício) e da fração (Habitação). Para este efeito foi produzido o “Método LNEC para avaliação e classificação da qualidade acústica de edifícios habitacionais”, o qual permite fazer uma avaliação global do conforto acústico na habitação. Este método inovador em Portugal origina uma Classe Acústica LNEC que permite representar com razoável fiabilidade o conforto acústico realmente sentido e a qualidade acústica da habitação. Este método pode ser aplicado a edifícios novos e a edifícios a reabilitar. De modo a permitir uma estimação dos custos médios necessários para transitar entre determinadas classes (e alcançar respetivo conforto acústico) é necessário possuir uma ferramenta de cálculo apropriada. Deste modo apresenta-se nesta comunicação uma ferramenta para estimar os custos de transição entre classes acústicas. Esta metodologia permite fazer escolhas mais fundamentadas nos processos de obtenção de determinado conforto acústico. Abstract The acoustic comfort in dwellings is essential to a peaceful and regenerative sleep. The achievement of this comfort is primarily obtained by reducing noise and increasing sound insulation of separating elements. To classify this comfort is necessary to conduct a comprehensive analysis of the habitation. This global analysis assesses the internal and external factors of the habitation, evaluating the acoustics of the environment (Vicinity), of the building (Building) and of the dwelling place (Lodging). Recently in Portugal was developed the “LNEC method for evaluation and acoustic quality classification of residential buildings” that allows an overall evaluation of the acoustic comfort in dwellings, resulting also in a “LNEC Acoustic Class” that portrays the real acoustic comfort sensed. Since this method can be applied to evaluate the acoustic comfort of new and of restored buildings, it is necessary a tool that gives an estimation of the needed investment to upgrade to a specific “LNEC Acoustic Class” (and achieve the respective acoustic comfort). In this communication is presented a tool that allows the estimation of that upgrade costs.
