“…Fouquet et al [62] defined two scenarios for a timber frame system, comparing incineration and landfill. Babaizadeh et al [31] also described different scenarios for building materials: 75% of wood is assumed to be used for landfill, the rest 25% is incinerated, and aluminum and PVC is assumed to be recycled. On the other hand, Monteiro & Freire [63], justify the end of life omissions by considering the limited importance of end-of-life stage impacts in South European single-family houses, demonstrated in Nemry et al [104] .…”

“…In order to analyze this aspect, a grid was organized to identify stages and modules described in EN15978 [13] -European reference in LCA of buildings. Nevertheless, several non-European cases [31][32][33][34] were included. Table 5 resumes the information modules covered by the LCA application.…”

Life Cycle Assessment (LCA) is globally recognized as one of the most complete methods for environmental assessment of buildings. Literature assumes that its applications in the building sector are prejudiced regarding complexity and difficulty. However, simplification is necessary, since it can facilitate LCA application in buildings. Moreover, growing interest on reducing environmental impact in the building sector, as well as the relevance of single-family houses on CO2 emissions have become key points on the wide spread of LCA.Therefore, this paper presents a research study about simplification in LCA recent studies applied to singlefamily houses. The review focuses on 20 cases that were analyzed according to ISO 14040, ISO 14044, EN 15978, and EN 15804 standards. The main objective was to identify the simplification strategies assumed in each paper, to clarify and to help to promote further developments on LCA. This paper examines system boundary definition, data sources, life cycle phases included, and environmental impact indicator calculated in case studies. Results show the variety of simplifications identified. They affect physical model definition, life cycle scenario definition and communication of results. In most cases, the functional unit was the complete building, the life cycle scenario definition included production, use and demolition phases, and the most considered environmental impact indicator was GWP. Finally, new challenges and recommendations were defined in order to establish common criteria to develop simplification strategies that allow results comparability in LCA of single-family houses.

“…Atzeri et al compared the performance of outdoor and indoor shading devices concerning the thermal and visual comfort of an openspace office located in Rome showing that although the use of shades always improves the thermal comfort, the energy demand could increase as an effect of particular configuration of the building [10]. Five common shading configurations in five climate zones defined by ASHRAE have been compared by Babaizadeh et al in order to provide guidance to decision about the design of shading systems in various types of facilities [11]. A very recent review on shading device types used different building types and different climatic regions has been proposed by Kirimtat et al underlining the importance of simulation modeling to address the problem [12].…”

A Pareto-based multi-objective optimization algorithm to design energy-efficient shading devices

h i g h l i g h t sWe present a multi-objective optimization algorithm for shading design. We combine Harmony search and Pareto-based procedures. Thermal and daylighting performances of external shading were considered. We applied the optimization process to a residential social housing in Madrid. t r a c tIn this paper we address the problem of designing new energy-efficient static daylight devices that will surround the external windows of a residential building in Madrid. Shading devices can in fact largely influence solar gains in a building and improve thermal and lighting comforts by selectively intercepting the solar radiation and by reducing the undesirable glare. A proper shading device can therefore significantly increase the thermal performance of a building by reducing its energy demand in different climate conditions. In order to identify the set of optimal shading devices that allow a low energy consumption of the dwelling while maintaining high levels of thermal and lighting comfort for the inhabitants we derive a multi-objective optimization methodology based on Harmony Search and Pareto front approaches. The results show that the multi-objective approach here proposed is an effective procedure in designing energy efficient shading devices when a large set of conflicting objectives characterizes the performance of the proposed solutions.
