The objective of this paper is to apply the life cycle assessment methodology to assess the environmental impacts of light steel framed buildings fabricated from cold formed steel (CFS) sections. The assessment covers all phases over the life span of the building from material production, construction, use, and the end of building life, in addition to loads and benefits from reuse/recycling after building disposal. The life cycle inventory and environmental impact indicators are estimated using the Athena Impact Estimator for Buildings. The input data related to the building materials used are extracted from a building information model of the building while the operating energy in the use phase is calculated using an energy simulation software. The Athena Impact Estimator calculates the following mid-point environmental measures: global warming potential (GWP), acidification potential, human health potential, ozone depletion potential, smog potential, eutrophication potential, primary and non-renewable energy (PE) consumption, and fossil fuel consumption. The LCA assessment was applied to a case study of a university building. Results of the case study related to GWP and PE were as follows. The building foundations were responsible for 29% of the embodied GWP and 20% of the embodied PE, while the CFS skeleton was responsible for 30% of the embodied GWP and 49% of the embodied PE. The production stage was responsible for 90% of the embodied GWP and embodied PE. When benefits associated with recycling/reuse were included in the analysis according to Module D of EN 15978, the embodied GWP was reduced by 15.4% while the embodied PE was reduced by 6.22%. Compared with conventional construction systems, the CFS framing systems had much lower embodied GWP and PE.

The Relationship

<p>The main objective of the research is to better understand the concept of human scale and the role that it has to play in the design of our urban environments. The need for a clearer, less ambiguous understanding of human scale is identified as a result of its poor definition and numerous manifestations across a multitude of literature. Human scale is an important part of design that flourished particularly in the middle ages, but has largely been neglected in the industrial and technological ages. Its remergence comes with the return of consideration for the comfort of people. Yet we cannot successfully apply a concept we do not wholly understand. Human scale is therefore redefined as a collective concept that embodies the multitude of existing definitions and treats them as aspects of a larger theory. As a broader but more comprehensive definition it better facilitates the identification and exploration of relationships with what are currently treated as separate urban design objectives, such as enclosure, in an endeavour to better understand the influence of human scale. The design case study proposes a design that tests the relationship between enclosure and human scale. A large site is chosen to display how human scale operates at urban, as well as architectural and detailed levels. Through aspiring to achieve a thorough human scale design, without any exclusive emphasis on enclosure, the process and the outcome still reveal that the theoretical relationship identified in the research (that aspects of human scale foster the formation of enclosure) is unavoidable in design practice. Enclosure simply results as a consequence of thorough human scale design. The research suggests that many urban design objectives may fall under human scale's sphere of influence meaning it is not a singular concept, but an ethic of design that has many desireable consequences. While the idealistic nature of the design may be unrealistic to achieve at present, it highlights the incompatibilities with contemporary approaches and succeeds in generating discussion.</p>

Building Information Modeling (BIM) and sustainable buildings are two future cornerstones of the Architectural, Engineering and Construction (AEC) industry. In Singapore’s context, the Green Mark (GM) scoring system is prevalently used to assess the sustainability index of green buildings. BIM provides the semantic and geometry information of buildings, which is proliferated as the technological and process backbone for the green building assessment. This research, through vast literature reviews, identified that the current procedure of achieving a Green Mark score is tedious and cumbersome, which hampers productivity, especially in the calculation of building envelope thermal performance. Furthermore, the project stakeholders work in silos, in a non-collaborative, manual and 2D-based environment for generating relevant documentation to achieve the requisite green mark score. To this end, a cloud-based BIM platform was developed, with the aim of encouraging project stakeholders to collaboratively generate the project’s green mark score digitally in accordance with the regulatory requirements. Through this research, the authors have validated the Envelope Thermal Transfer Value (ETTV) calculation, which is one of the prerequisite criteria to achieve a Green Mark score, through a case study using the developed cloud-based BIM platform. The results indicated that using the proposed platform enhances the productivity and accuracy as far as ETTV calculation is concerned. This study provides a basis for future research in implementing the proposed platform for other criteria under the Green Mark Scheme.

AbstractIn Industrial Design, new design visualisation tools are emerging offering significant benefits to the designers. However, studies show alongside some benefits, new tools can also inhibit designers' creativity or cause time inefficiency if used in the wrong context. Thus, understanding which tools to use and when during the design process is increasingly necessary to ensure the best use of resources in design practice. Existing research on understanding the performance of design tools and the resulting frameworks for comparing tools are either specific to certain tools or highly generalised making evaluation across different design tools challenging. As such, this paper reports the creation of a more comprehensive framework of design tool characteristics to facilitate a better understanding of design tools and their uses. Demonstration of application of the framework is also given in the form of a case study on the use of Digital Sketching and its comparable tools with four practising designers. In conclusion, we show how the Design Tool Characteristics (DTCs) framework is an effective way to understand design tools, with further implications for design tool development.

Programming and scripting can be used to activate a 3D parametric model to create a more intelligent and flexible building information model. There has been a trend in the building industry towards the use of visual scripting that allow users to create customized, flexible, and powerful programs without having to first learn how to write traditional code. Using visual scripting, users graphically interact with program elements instead of typing lines of text-based code. Nodes are created and virtually wired together; they can be numbers, sliders for adjusting values, operators and functions, list manipulation tools, graphic creators, and other types. Text based coding programs such as Python can also be used for the creation of custom nodes when greater flexibility is desired. Examples from professional firms include scripts that help automate work in the office to increase efficiency and accuracy (e.g. create escape routes, renumber rooms by levels, create documentation), assist in form generation (e.g. parametric design of metal panels, rebar generation, coordination between Revit and Rhino), analyze BIM files (e.g. terminal airflow, visual loads and capacity), and provide analysis results (e.g. daylighting, thermal comfort, window optimization). One can learn the basic steps of learning a visual programming language through the use of Dynamo within Autodesk Revit. The example used is for a façade component that changes based on the sun's altitude.

<p>Within joint venture De Groene Boog, BESIX will design and construct a 2.2 km long tunnel in the North of Rotterdam for a new highway connection. Its design process entails the structural design of many similar tunnel sections and thousands of foundation and sheet piles, as well as the production of a detailed 3D Building Information Model and numerous technical drawings. To effectively perform these tasks and efficiently cope with design changes, an automation strategy has been developed that benefits from the tunnel’s repetitive geometry. The digital models are set up parametrically, while software innovations allow to dynamically transfer data between and combine the strengths of multiple software packages. Through standardization we aim to automate structural calculations and drawing production.</p><p>This paper will present the proposed automation strategy for the ongoing design process of the tunnel and will evaluate its benefit during the detailed design phase compared to traditional methods. The present project forms the first application of parametric design and automation of such magnitude being developed in-house at the BESIX Engineering Department. It reflects our ambition to use these techniques for tackling the ever increasing challenges within the construction industry and simultaneously boosting productivity and the quality of the final product.</p>
