LCA was carried out to determine the environmental
impacts of the production and construction stages of an
average prefabricated timber house produced in Germany
as well as its particular building elements (1 m² inner/outer
wall, 1 m² roof element, 1 m² ceiling element).

Proper construction of components and wood finishing significanty improve the durability of wooden facades

Design details of wood products in claddings are discussed

The main objective of this contribution is to analyze selected variants of constructions in terms of environmental and
economic sustainability characteristics, as part of a broader assessment of permanent sustainability, by applying the life-cycle assessment (LCA) and life-cycle cost (LCC) methodologies within specified assessment boundaries.

These notes on Modular Coordination in the Buildable Design Appraisal System are produced as part of BCA's Buildability Series. Its objective is to introduce designers to the concept of modular coordination and its benefits. At the same time, it gives some practical advice on the application of modular coordination using actual projects as examples. The recommended modules in these notes take into consideration the need for flexibility in design and the sub-module has been introduced for this purpose. As modular coordination becomes more widely practised in the local industry, these notes may be revised and the recommendations will be reviewed to achieve a higher level of modular coordination that will benefit the building industry.

The need for findinglong-terms solutions that warrant continuing human existenceand well-being is far more compelling than that of findinga proper terminology to describe the human need. In thisrespect, the debate on the terms “green,” “sustainable,” or“ecological” architecture is not terribly important.

Careful selection of environmentally sustainable building
materials is the easiest way for architects to begin incorporating
sustainable design principles in buildings. Traditionally,
price has been the foremost consideration when comparing
similar materials or materials designated for the same function.
However, the “off-the-shelf” price of a building component
represents only the manufacturing and transportation costs,
not social or environmental costs.

With an increasing societal need for temporary buildings, while construction industry faces resource and time efficiency challenges, factory assembly of modular buildings can be a solution. This case study at a start-up company uses experiences from assembly system design and eco-design literature to propose green lean design principles to be used in the design and development of building modules and their assembly stations. The eco-design strategy wheel is used as a basis and adapted for the assessment of green and lean building manufacturing

The goals of sustainability are to meet people's basic needs and improve their quality of life while simultaneously ensuring that the natural systems, resources, and diversity upon which they depend are maintained and enhanced, both today and for future generations. Construction activities over a facility's life cycle are also connected with the broader problems and issues affecting the environment, including global warming, climate change, pollution and the depletion of valuable resources. Built facilities significantly impact human health, comfort, and productivity. Modular building is becoming increasingly popular in many countries due to its many benefits, including greater construction efficiency and productivity. This study investigated how modular building can support sustainability goals in the built environment via a deep case study of ‘The Stack’, a recently completed modular rental housing block in New York City. The building's architect and manufacturer were interviewed for the case study and the design, manufacturing and construction process analysed to examine how modular processes can contribute to achieving the goals of sustainability. The ultimate goal of this study is to improve the processes involved in modular construction to help all stakeholders to achieve the goals of sustainability.

A new structural typology of a hybrid purlin, made of type C cold steel and rectangular laminated wood (SWP), is presented in this paper. As a result, improvements on the most commonly used steel purlins are achieved, by substituting some of the steel sections for wooden sections. Although the wooden section is weaker and has a lower elastic modulus than the steel, the overall dimensions of the SWP are no larger than the type C steel purlin. In comparison with the steel ones, SWP purlins achieve a far better performance in terms of sustainability and are of lower weight, so less material will be needed for the main structure of the building. The behavior of each material in its position and the improvements in terms of sustainability and lower weight are analyzed as a function of span length, slope, and design load. To do so, the influence of both tensile stress and deformation design criteria in each section and the influence of those criteria on the choice of material and the lengths of each section are all examined. Finally, a design guide for the SWPs is presented that applies the proposed technical specifications.
