“…Para Heralova (2017) o CCV é um método de análise econômica voltada para todos os custos relacionados à construção, operação e manutenção de um projeto de construção durante um período de tempo definido. Potkany, Vetrakova e Babiakova (2015) afirmam que os custos de cada fase do ciclo de vida dos edifícios são influenciados por diversos fatores, tais como: propósito, espaço, construção e solução de materiais do projeto.…”

“…Fonte: adaptado de (KOVACIC;ZOLLER, 2015) De forma geral, os custos do ciclo de vida consistem em custos de investimento inicial (geralmente custos de construção) e os custos subsequentes (pagamentos comuns, tais como energia, serviços, limpeza e manutenção, custos de renovação ou substituição) e custos de demolição (HERALOVA, 2017). Kovacic e Zooller (2015) relatam que os interesses de custos do ciclo de vida divergem em grande parte para as diferentes partes interessadas.…”

“…Implementing green goals at the construction phase could improve environmental performance [29], and is considered to be a key feature of the next generation of green performance evaluation models [30]. Furthermore, it is well-known that appropriate planning for green building can be done at a low cost in the early stages of construction with enormous savings later [31].…”

Green Performance Evaluation System for Energy-Efficiency-Based Planning for Construction Site Layout

The location of temporary facilities in a construction project and the entire site layout plan directly affect project objectives such as time, labor cost, and material transportation and handling. The layout of construction sites also affects entrainment factors such as energy consumption, carbon footprints, and overall construction operation productivity. While site layout planning has been intensively investigated from a project objectives perspective, there have been very few studies of energy-efficiency-based planning, or of the sustainability performance of site layouts. This study developed a green performance evaluation system aimed at improving the sustainability of construction site layouts. The identified factors include six sustainable evaluation categories covering energy conservation and environmental protection, people-oriented principles, construction efficiency, intensity of economic growth, intensity of space use, and the overall control of process. An analytic hierarchy process (AHP) was adopted to determine the weight of each attribute and a fuzzy comprehensive evaluation method was established to carry out the evaluation. The 23 attributes adopted in this paper were identified in the literature; however, the major contribution of this paper is the development of a green performance evaluation system. This system integrates both qualitative and quantitative attributes and provides an overall evaluation of the environmental effectiveness of a construction site layout. The proposed evaluation system was validated with a commercial building project. The average utilization ratio of the case study site was calculated as 94%, and lessons learned are discussed in this paper. The case study analysis identified available site spaces around the building and examined how the arrangement of resources and facilities ensures effective connection between construction activities. The findings showed that the facility’s layout plays a crucial role in energy consumption and green performance. The proposed system will support construction project managers to create high-performance construction site layouts in more scientific and systematic ways.

“…It has become one of the most important tools for strategic planning nowadays. Moreover, feasibility analysis considers as an effective methodology for the strategic management of projects in various investment and economic activities, which lead to the investment decision-making over the project' whole life with the least possible degree of uncertainty (risk) [3]. The feasibility analysis has been generated from the economic theory core to support investment decision-making under a certain degree of risk and/or uncertainty and stemmed from the existence of many internal and external variables concerning with the future that might affect decisions [4][5].…”

The views at the construction field emboss that construction parties are looking for a higher benefit during implementing aspects of any project. The feasibility study is one of the serious and significant matters in construction sectors as well as in other engineering fields as it has a high impact on investment decision-making. To gain rigorous decisions from decision-makers or contractual parties (client, consultant, and contractor), there is a need for valuable feasibility studies in any construction project. This paper aims to study the influence of some identified factors on feasibility studies as well as the extents of priorities of various feasibility studies. In this paper, the critical factors that have an impact on sequences of initial feasibility studies during the lifecycle of a construction project were identified as well as the associated studies (legal, environment, marketing, technical, managerial, schedule, financial and economic). In this study, 12 factors were identified, analyzed, and thoroughly discussed to have recommendations of their impact on initial feasibility in construction projects in Iraq via a questionnaire survey and a series of expert interviews conducted in Iraq. The Analytical Hierarchy Process (AHP) as a multi-criteria decision support system was adopted to examine the weight of each factor. In addition, an analysis by the Relative Importance Index (RII) was carried out to rank eight types of feasibility studies in terms of their perceived importance. The results of AHP indicated that the local shortage of database about the feasibility study was the most critical factor. Indeed, RII's result showed that all kinds of feasibility for construction projects in Iraq are not adopted by the client. In fact, the economic feasibility study was the most popular than others.
