Excellence in communication and coordination is required between stakeholders and automated interdisciplinary change management to meet needs and expectations in the construction industry. Building Information Modeling (BIM) offers numerous benefits, including reducing construction time, cost, and risk while improving project quality, communication, and coordination. However, there are still significant barriers to BIM implementation. Since Iran is in the early stages of BIM implementation, a roadmap for adopting BIM in Iran's construction industry is designed for the first time to exploit BIM benefits in this paper. Face-to-face interviews were conducted with professionals to structure the roadmap. In addition, online interviews were carried out with 16 experts. Furthermore, a Delphi-based approach was employed to reach consensus. The roadmap consists of six main pillars with 53 activities designed to create a matured BIM plan based on local culture and needs. And the roadmap begins with assigning a strong leadership to lead the process. The industry is expected to be motivated to adopt BIM as it learns the benefits associated with BIM. Then, it continues with developing related best practices, rules and regulations. In the third stage, the roadmap encourages the industry to provide the required education and training. In the next pillar, the roadmap follows the establishment and development by defining a contractual platform. In the fifth pillar, the quality of BIM and its results will be measured and compared with expectations and pre-defined goals. Eventually, the government will provide a continuous BIM implementation. The study is expected to facilitate BIM implementation in the Iran construction industry which will improve the quality of Project Management Body of Knowledge (PMBOK) practices. It will help to culminate tangible and intangible project deliverable by reducing time, cost, risks and improving overall quality. Therefore, all stakeholders satisfy the final outcome beside resolving conflicts and interferences.","PeriodicalId":472764,"journal":{"name":"Jounarl of Building Design and Environment","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135058314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"A Statistical Analysis of the Energy Performance Characteristics for the Residential Building Stock in Jordan","authors":"Reham Alasmar&Yair Schwartz&Esfandiar Burman","doi":"10.37155/2811-0730-0201-8","DOIUrl":"https://doi.org/10.37155/2811-0730-0201-8","url":null,"abstract":"The residential sector is responsible for the consumption of 46% of the building’s total primary energy consumption in Jordan. The Jordanian housing stock will need to be significantly improved to meet the government’s commitment to reduce national emissions by 2050. This research aims to examine the available statistical data on residential buildings, to help better understand the current state of housing stock in Jordan and pave the way to generate a national housing stock model, as well as to identify opportunities in improving the energy efficiency of these buildings. The study synthesised data from the Department of Statistics housing survey and the Jordan Green Building Council survey to investigate the Jordanian national housing stock. The aggregated data was examined using a descriptive statistical analysis method. The data was then merged to provide aggregated datasets with detailed building characteristics. The study successfully characterized residential buildings archetypes and identified a range of typical thermal performance-related building characteristics (e.g., envelope properties, HVAC systems, lighting systems, etc.). The findings of the statistical analysis can be useful for policymakers in Jordan to gain insights into the current state of the housing stock, identify trends and patterns, and make informed decisions and initiatives such as the improvement of regulatory building code requirements for energy efficiency.","PeriodicalId":472764,"journal":{"name":"Jounarl of Building Design and Environment","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135600122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
