Wooden housing in the pillar-beam construction system
Journal of Engineering Research, 2023
Building in wood with rationalized components is an alternative to meet the demands of the buildings sector, especially regarding the use of environmentally friendly materials and low energy wood biomass for final uses of civil construction. In addition, wooden construction systems have advantages such as short construction time and low solid waste production. These aspects and the opportunity to encourage the use of wood as a building system favor studies and research on these systems in the academic sphere and in the training of professionals committed to sustainable development, quality, and performance of wooden buildings. This work seeks to show the column-beam timber construction system and an application. Literature and deepening in taxonomic studies on the construction system in wood and the material-uses, advantages, disadvantagessupported the development of a rationalized design process for a dwelling in wood structure of the column-beam type and wood fence with tongue and groove horizontal panels. The built house resulted from a process that associated constructability, multiple performances, and safety.
Evaluating the Ecological Architecture: using the Wooden Material
A+ArchDesign , 2017
In consideration of many concepts such as “sustainable, ecological, green, climate and environment-friendly, high performance, intelligent, passive, carbon-neutral buildings” the objective of the applications, becoming evident today, is to produce structures, making us respect and take care of the “nature” with reference to the risk of failure of future generations to survive. The objective of this study is to draw attention to the utility of wood, a renewable material, in this respect in sustainable, organic and ecological architectures, which have gained more importance nowadays, based on the increasing interest in natural life and use of natural materials in the world in recent years. In this regard, technical specifications of wooden materials are mentioned, wooden-material based several structures are analyzed and samples are provided thereof.

Method for the architectural design of wood houses in Portugal
Informes de la Construcción, 2020
The goal of this study is to propose a method for the architectural design of wood houses in Portugal. Construction and manufacturing companies were interviewed to understand the wood house market. A case study was developed by simulating four variations of a project, including different wood construction systems (wood frame, post and beam, logs, and cross-laminated timber). Based on the identified problems, a design method was defined by using decision support tables, lists of procedures and optimization strategies. A multi-criteria decision support process was proposed to assist in the assessment and selection of the “best” solution among the potential options. During the program phase, the use of a catalogue of architectural typologies with construction and formal systems promotes the process’ optimization. In the sketch design phase, the adoption of an assessment process, specific design procedures and pre-set strategies (durability, construction integrity, economy) aims to assure construction quality.
Proposal of a Methodology for the Architectural Design of Timber Houses
This paper presents the principles of a method for the architectural design of timber houses based on the experience gained by timber companies. This proposal has as its major goal the challenging of the scenario of countries like Portugal where a shift in the design and construction methods integrating wood as a material could result in a much more sustainable habitat. A set of interviews was carried out with Portuguese companies in the sector of timber houses. They were questioned about their customers, design methods, the architect’s role and the choice of structural systems. Based on the interviews it was possible to characterize the market and identify the main procedures about design. The most relevant ones were the importance of the architectural type definition, the support of a catalog, the relationship between formal and structural types and the architect’s lack of knowledge about timber. The collected information pointed to an architectural design method to be used by Portuguese architects who, until now have often played a secondary role when a timber house was designed partly because the timber companies dominate the whole process. Some of these companies offer catalogues of design solutions that support customer’s choices. The architects generally reject this type of method because of its supposed uncreative and impersonal results. The method here presented through some basic principles aims at collecting some positive lessons from the catalogue method, defining a process based on the recognition of Formal types and Construction types. This is the framework of a tool intended to help the Portuguese architects to deal with the range of the options available (solutions, companies, structural systems) and a support to help in deciding which construction system to choose.
Sustainable Construction—Technological Aspects of Ecological Wooden Buildings
Energies
Wooden construction constitutes a specific branch of the building industry that focuses on high-quality materials, a developed sense of aesthetics connected with comfort and functionality, and concern for ecology and durability. This type of construction has a positive effect on human quality of life. This article focuses on modular frame construction and technological aspects of wooden houses built according to Canadian or Scandinavian technologies. Taking weather conditions of Scandinavian countries into consideration, timber is a popular building material, which, when preserving certain parameters such as density of rings, may provide durability of a modular wooden building even up to 200–300 years. This article is a review and presents the possibility of producing frame buildings in Europe (Poland) in accordance with the applicable standards, including a heat transfer coefficient U = 2 [W/(m²·K]. In Poland, wooden frame buildings can be traced back to the 14th century. Wooden fr...
Wooden Residential Buildings – A Sustainable Approach
Bulletin of the Transilvania University of Braşov: Series II: Forestry • Wood Industry • Agricultural Food Engineering, 2016
Both round and handle produced (sawn or rough-hewn), timber constitutes one of the oldest building raw materials. Wood can be engineered to produce structural beams and boards. Today, wooden housing is the most valuable and viable alternative to replace masonry. In turn, it is a modern model, whereas it presents good attributes of raw materials rationalization, water-free processing, work site cleaning, and rapid production. The strong industrialization of timber housing with prefabrication of parts should be the centre of attention in the future, consonantly with housing shortage in many countries, particularly in developing and underdeveloped ones. This paper aims to present a state of the art about timber housing topic and its aspects.

The Development of a Tall Wood Building
Climate change and demographical increase in developing countries are inducing us to reconsider the way we build the buildings. Concrete and steel have already reshaped our cities for 2 centuries but problems related to the non-sustainable aspects of steel and concrete are now appearing in their productive system, characteristics, creation process and energy demands. It is necessary to find new solutions, especially regarding high-rise buildings which will be one of the main typologies of construction in a more and more urban future scenario. The only structural material that can tackle the future demand of building is wood as Mass Timber Products. There are already several successful examples of how this material could answer architectural challenges. As architects, we have the power to choose how the building is built and realized. On our profession stands a great chance to increase the realization of sustainable buildings. Since the beginning of mankind, wood structure was one of the most common types and this trend was decreased only in the last 2 centuries thanks to the rise of steel and concrete structures. The 21st century can be instead the century of the renaissance of wood an the motifs are really a lot. Sustainable, renewable, zero impact and other qualities certified that it must be considered as possible solution. The context of the competition Wien Heiligendstadt Wohnen und Arbeiten is a pretext to show how an international competition can adopt Mass Timber as technological solution compared with a concrete solution. Showing the plus points and demerits of wood as a structural material is the main aim of this Master Thesis. Additionally, this Master Thesis aims to demonstrate the feasibility of an on field context rather than a theoretical solution, while also displaying the current status of wood technology.
Classification of Wooden Housing Building Systems
BioResources, 2016
Wooden housing is one of the most sustainable building alternatives. In many European and North American countries, wooden houses provide the most common, economical, and practical solution for construction. The timber buildings present adequate levels of durability, acoustics, and thermal comforts. Despite their popularity, wood houses do not have a standardized classification to define and organize their main aspects. In literature dealing with timber construction, most authors emphasize structural systems for large spans (bridges, hangars, roofs, etc.). The presence of some classifications of timber construction results in unclear issues, and few studies have covered and regarded wooden buildings as residential construction typologies. Accordingly, this paper proposes a classification that connects the aspects and details of wooden housing materials in relation to the industrialization level and chronological origin. We expect this classification to assist in a better understanding of distinct wooden housing techniques commercially produced worldwide, diffusing their concepts and possibilities as forestry-timber products.
