Assessing the Impact of Air Leakage on the Hygrothermal Performance of Wood-Frame Walls Under Historical and Future Climates

Air leakage is a crucial factor when assessing the hygrothermal performance of wood-frame walls since it can lead to moisture accumulation during the cold season. The seriousness of this prob-lem may change in a warmer climate in the future and hygrothermal simulations are widely used as a tool to predict this effect. However, since 2D models are required for detailed air leakage as-sessment and the high number of input variables leads to having to conduct thousands of simula-tions for a single type of building cladding, downsizing the simulation grid to the lowest number of cells is a crucial task to help ensure reduced computational time. Using a hygrothermal simulation tool, the steps needed to build the smallest 2D grid were explained; as well, convergence and ac-curacy of the results were evaluated and the functional relations between air leakage rate and air permeability of the insulation were clarified. Hygrothermal simulations were performed for wood-frame walls having brick veneer and stucco cladding for three Canadian cities: Whitehorse, Van-couver, and Ottawa. While the air leakage rate has a significant impact on the inner surface of OSB, wind driven rain is the key factor on the outer surface. The performance of stucco cladding is worse than brick in all cases and the future climate may reduce the risk of mould growth on the in-ner surface of OSB in all cities. The results also show that the simulation time can be reduced by 90%, with negligible loss of accuracy, when comparing fine to optimized meshes

OSB and Marine Plywood: Performance Comparison for use with Light Steel Frame Walls in Brazil

The use of light steel frame and wood frame in Brazil is still recent, hence there is little information about the durability of these technologies applied in Brazilian climate conditions. The wood-based boards are used as a part of the light steel or wood frame walls and are designed to contribute to the wall structural behavior (horizontal reinforcement and resistance to suspended loads). Once the information if such boards meet the DL (design life) set in the Brazilian code of residential building performance is still unknown, this paper analyses the technical characteristics of two woodbased boards - OSB and marine plywood - aiming to gather more information concerning durability under liquid water action. Thus, tests were carried out on samples of these two boards to evaluate their behavior against liquid water and after accelerated ageing test. In all cases, OSB showed to be more sensitive to early degradation than plywood

Assessment of Moisture Performance of National Building Code Canada Compliant Wall Assemblies under Climate Change

Due to climate change, higher temperatures and rainfalls are expected to happen in some areas of Canada, which might increase the climate loads on buildings and lead to premature degradation of moisture-sensitive materials in wall assemblies. To investigate potential durability issues in three cities across Canada (Ottawa, Vancouver and Calgary), code-compliant wood-frame walls with two types of claddings, stucco and brick, were simulated using Delphin 5.9. Two different climate data sets, historical and future when a global warming of 3.5ºC is expected to be reached were used. The hygrothermal performance in terms of mold growth risk was analysed with respect to cladding types, considering air leakage. All the three cities are similarly warmer in the future. However, wind-driven rain (WDR) is higher in Vancouver than in Ottawa and Calgary. With brick cladding the relative humidity is kept below the threshold for mould development only in Ottawa and Calgary. With stucco in future, while Ottawa shows greater mould indices than historical, Calgary shows opposite behavior. The results suggest that the risk of mould growth due to air leakage may decrease in the future

Grouting of ceramic tiles: influence of joints in stress relief.

Este trabalho apresenta uma revisão bibliográfica a respeito dos rejuntes para revestimento cerâmico. A nomenclatura internacional é explorada e os tipos de rejunte e seus empregos são enumerados. Para embasar o leitor sobre o reves-timento cerâmico, os principais conceitos a ele relacionados são exibidos de forma sucinta. Uma vez que o rejunte é um componente importante do revestimento ce-râmico, suas funções dentro desse subsistema são abordadas em detalhes. O as-pecto de alívio de tensões é amplamente comentado, uma vez que essa é uma função essencial do rejunte, particularmente no caso de fachadas. Ao final, são abordados os aspectos de preparo e aplicação dos rejuntes, particularmente os produtos cimentícios. O rejuntamento de locais específicos, como encontros com selantes e interfaces com aparelhos sanitários são detalha-dos com vistas à diminuição da ocorrência de manifestações patológicas futuras. No trabalho experimental, painéis em forma de laje revestidos com placas cerâmicas são submetidos à flexão até a ocorrência de desplacamento, objeti-vando detectar qual a influência da largura da junta e do tipo de argamassa ade-siva na ruptura do corpo-de-prova. Os resultados indicam que a largura das juntas de assentamento assumem importância apenas quando a argamassa adesiva apresenta alta resistência de aderência.This study presents a bibliographical revision regarding the ceramic tile grouts. Here, the international nomenclature is explored and the types of grouts as well as its employments are enumerated. To base the reader on the ceramic tile cladding, its main concepts are shown succinctly. Being the grout an important component of the ceramic tile cladding, its functions in this subsystem are broached in details. The aspect of stress relief is widely mentioned, for this is an essential function of grout, particularly in the case of facades. In the end, the aspects of the preparation and the application of grouts are broached, particularly the cementitious products. The grouting of specific places such as meetings of sealants and interfaces with sanitary devices is detailed viewing the decrease of the occurrence of future problems. In the experimental study, panels in flagstone form tiled with ceramic plates are submitted to flexion until the occurrence of rupture of these panels, aiming to detect the influence of the joint thickness and of the type of the adhesive mortar in the rupture of the sample. The results indicate that the nesting joint thickness only assumes importance when the adhesive mortar presents high resistance of adherence

What is that little voice inside my head? Inner speech phenomenology, its role in cognitive performance, and its relation to self-monitoring

International audienceThe little voice inside our head, or inner speech, is a common everyday experience. It plays a central role in human consciousness at the interplay of language and thought. An impressive host of research works has been carried out on inner speech these last fifty years. Here we first describe the phenomenology of inner speech by examining five issues: common behavioural and cerebral correlates with overt speech, different types of inner speech (wilful verbal thought generation and verbal mind wandering), presence of inner speech in reading and in writing, inner signing and voice-hallucinations in deaf people. Secondly, we review the role of inner speech in cognitive performance (i.e., enhancement vs. perturbation). Finally, we consider agency in inner speech and how our inner voice is known to be self-generated and not produced by someone else
