“…Passive solar gain, ventilation, day-lighting and vision are the building's needs that are responded by window design. Reviewing the LCA studies of window system led this research to select the following parameters as the most effective indicators of window system on minimising buildings environmental impact through their whole life cycle: Window to Wall Ratio (WWR); Glazing type Frame type; Shading (Amaral et al, 2016;Cheung et al, 2002;Goia, 2016;Nedhal Al-Tamimi, 2012;Radhi & Sharples, 2013;Su & Zhang, 2010;Yang et al, 2015;Citherlet et al, 2000;Eskin & Türkmen, 2008;Lee et al, 2013;Switala-Elmhurst, 2014;Weir & Muneer, 1998;Asif et al, 2002;Salazar & Sowlati, 2008;Babaizadeh et al, 2015). Solid envelope design and effective parameters: The choice of solid envelope materials and assemblies are one of the main responsible for buildings energy demands for use, maintenance, initial and recurrent embodied energy and the energy used in demolition and disposal of materials.…”

Life Cycle Assessment (LCA), developed over 30 years ago, has been helpful in addressing a growing concern about the direct and indirect environmental impact of buildings over their lifetime. However, lack of reliable, available, comparable and consistent information on the life cycle environmental performance of buildings makes it very difficult for architects and engineers to apply this method in the early stages of building design when the most important decisions in relation to a building’s environmental impact are made. The LCA quantification method with need of employing complex tools and an enormous amount of data is unfeasible for small or individual building projects. This study discusses the possibility of the development of a tool that allows building designers to more easily apply the logic of LCA at the early design stage. Minimising data requirements and identifying the most effective parameters that promise to make the most difference, are the key points of simplification method. The conventional LCA framework and knowledge-based system are employed through the simplification process. Results of previous LCA studies in Australia are used as the specific knowledge that enable the system to generate outputs based on the user’s inputs.Keywords: Life Cycle Assessment (LCA), early design stage, most effective parameters, life cycle environmental performance

“…Scripting with LUA can access all of the Ecotect functions without typing commands, and therefore, they can be flexibly integrated with other programming languages such as Java™ in the automation process. Finally, many building environment studies, including daylight (Al-Sallal 2007; Kim and Seo 2012) as well as energy simulation (Sadafi et al 2011;Al-Tamimi and Fadzil 2012), have also proven the effectiveness of Ecotect as a simulation tool.…”

Although environmental performance-based methodologies are increasingly considered in the early design stages due to their potential for improving the final building performance, few studies have scrutinized the interoperation of floor-plan design and thermal zoning for the purpose of optimized building energy use and indoor comfort. The absence of effective tools, which aid designers incorporate an environmentally adapted thermal zoning into the space arrangement process, invokes the strong necessity for a new space layout design methodology based on optimal thermal zoning. Thus, this paper presents a highly practical decision support tool named EASL (Environmental Architecture Space Layout) optimizer to bridge the gap between thermal and spatial zoning within architectural workflows. In this software, performance evaluation using the whole building simulation tool (Ecotect) and zone-based layout creation techniques is integrated for the automated generation of an optimal geometry of space and envelope glazing, employing a simulated annealing algorithm. As a beta version, EASL uses typical office building space programmes and adopts four major performance criteria for evaluation such as annual energy use intensity, Predicted Mean Vote, daylight level, and room shading. Utilizing the tool provides two major strengths: (1) by introducing performance indicators to floor planning with an easy-to-use computerized interface during early design stages, architects can maximize the potential use of other sustainable strategies and technologies for later design decisions and (2) a time-efficient thermal zoning optimization process is achieved by exploring various scenarios that users are interested in testing. To this end, a case study was conducted of an office building located in South Korea using the developed simulation tool. The existing plan was tested to be rearranged and compared with the optimal layout obtained from EASL. The experimental findings demonstrate that this software can be implemented in practical operations, advancing early processes of design work, and be extended to embrace broader future applications to promote innovative environmental buildings.

In this paper, a common social housing archetype design was studied in order to improve the energy and cost performance. The focus is on evaluating the effects of some parameters of the design of the façade in particular: the size of the windows and the optical and thermo-physical properties of the components. The aim is to obtain cost optimal energy efficient scenarios in accordance with the Recast of Energy Performance of Buildings Directive (EPBD Recast) by determining efficient thicknesses of the insulation for the exterior walls and efficient window sizes and types of glazing for each orientation, simultaneously. The parameters of the façade are optimized in order to obtain the dominant values and ranges in terms of energy and cost. There are remarkable differences in the dominant options for the thickness of the insulations, as well as the type and size of windows: they depend on whether they have a north, south and east–west orientation. The decision makers should design each façade in dependence on its orientation to determine its optimal optical and thermo-physical properties in terms of its cost and its consumption of energy. A reduction by approximately 5% in the life cycle cost and 17% in the primary energy use was achieved through the optimization of the base case.
