Multiple sustainability standards and rating systems have been developed to draw attention to constructing sustainable buildings. The Pearl Rating System (PRS) is a mandate for all new construction projects in Abu Dhabi. Hence, it is important to understand the main components, advantages, and limitations of the PRS. The feasibility and the practical relevance of the PRS are still being studied. This paper addresses this gap and critically evaluates the PRS against some of the well-established rating systems like LEED and BREEAM. The analysis suggests that the PRS considers the cultural aspect of sustainability, in addition to the environmental, societal, and economic aspects. It was also found that most rating systems, including the PRS, have a very superficial inclusion of life cycle assessment (LCA). The paper finally concludes with other observations and outlook for a more robust implementation of the PRS.

Two Phases

This paper presents a discussion with data on factors related to the in-place density measurement of asphalt pavements. A review of the literature traces changes to asphalt density measurement technologies over the past 60 years. Two phases of investigation then are presented in which in-place density was evaluated for an ongoing study of environmental effects at a test section in Columbus, Mississippi. A series of laboratory and field activities was performed in Phase 1. In Phase 2, studies were made of laboratory drying practices of specimens that were cored after an extended period of field aging. The key conclusion from these efforts was that ASTM D7227 might not remove sufficient moisture from some specimens to achieve accurate density measurement when pavements have been exposed to moisture for extended periods of time. This paper presents a case with an average error in air void measurement of 0.9% (measured 9.1% when 10% was correct) for specimens that were cored, dried according to ASTM D7227, and then measured for mass in air 1 day later. This finding is of most concern to rehabilitation and research work in areas in which aggregates have high potential for absorption but is of no concern to new construction projects. Furthermore, the work presented here validated the use of ASTM D7227 in circumstances in which mixtures were exposed to moisture for short periods of time. The work also suggested three options to take to accurately measure in-place density for performance testing of aged pavements that contain high-absorption aggregates (i.e., dry in oven, develop correlation equations, or dry for several weeks).

Sustainability Principles

INTRODUCTION Sustainability principles have become an integral part of the design and construction process for many new construction projects. The selection of the project delivery method (PDM) is extremely important in the effective execution of the project, and plays a critical role in establishing communication and coordination between the key entities: owner, architect, and contractor. The goal of this paper is to hopefully serve as a starting point for further discussion to improve on the AEC industry's current integration of sustainability principles in PDMs. The first step consists of an assessment of current project delivery systems from a sustainable design perspective. This is followed by a determination of the current limitations, and examination of the various disruptions in the industry. Various literature sources are analyzed to form a framework to discuss improvements and optimization strategies beyond the current system. Thereafter, proposed solutions are introduced at both stakeholders, as well as PDM scales. In this paper, the focus for the conducted analysis and proposed methodologies is predicated on new construction projects instead of retrofits due to the resources available. However, the principles can similarly be applied to retrofit scenarios as well, depending on the specific requirements of the individual project at play.

Purpose The increasing urbanization of the built environment has bolstered the need to promote green Building Information Modeling (BIM) initiative in new construction projects and the rehabilitation of old premises. This study aims to explore and examine the key benefits of the implementation of BIM and sustainability practices in the built environment. Design/methodology/approach The study gathered the worldwide perceptions of 220 survey participants from 21 countries which were analyzed using descriptive and inferential analytical methods. The identified individual benefits of green BIM were further categorized into their underlying clusters using factor analysis. Findings The key benefits are related to enhancing project efficiency and productivity, ensuring real-time sustainable design and multi-design alternatives, facilitating the selection of sustainable materials and components, together with reducing material wastage and project’s environmental impact, among others. The study analyzed and compared the perceptions of the diverse groups of the respondents as well. Practical implications Effective blueprints and insightful recommendations for enhancing the various stakeholders’ capacities to implement green BIM in their construction projects were put forward to achieve the aim of sustainable smart urbanization. Originality/value The study identified salient benefits of the adoption of BIM and sustainability practices. The proper integration of these concepts and the execution of the recommended useful strategies by construction stakeholders, policymakers and local authorities will enable the built environment to reap the gains of its implementation.

Purpose This paper aims to analyze how nearby property prices are affected by new construction projects in Stockholm. If there is an impact on property prices, the authors endeavor to investigate whether the effects vary among different areas within the municipality, for different groups of inhabitants and for different types of housing (i.e. public versus private housing). Design/methodology/approach The authors use a difference-in-difference specification in a hedonic model, and the sample consists of more than 90,000 observations over the period 2005-2013. Findings The results are robust and indicate that house prices in nearby areas increase following the completion of infill development. The results also indicate that infill development has a positive spillover effect on nearby dwelling prices only in areas with lower incomes, more public housing units and more inhabitants born abroad. Originality/value It provides an analysis on how nearby property prices are affected by new construction projects by creating a restricted control area, so as to make the treatment group and the control group more homogeneous. Thus, it mitigates any potential problems with spatial dependency, which can cause biased standard errors.

The City

Historians have extensively explored the topic of architecture in Mexico City in the 20th century. From the relationships between politics, public patrons, new construction technologies, and new idioms of modernism, the impressive story of architecture in this megalopolis continues to astound and captivate people’s imaginations. Architecture was a channel that politicians used to address housing, education, and health care needs in a rapidly growing city. Yet scholars have not been especially concerned with private construction projects and their influence on the process of shaping and being shaped by the visual representation of Mexico City. Private building projects reveal an alternative reality of the city—one not envisioned by politicians and public institutions. Private construction projects in the historic city center are particularly interesting due to their location. These buildings are built on ancient clay lakebeds and volcanic soil on which the Aztecs first built the city. Not only are these buildings located in the heart of the city, the buildings in the rest of the historic district are also sinking. Any building in a historic district that has withstood the test of time should be an object of interest to scholars. The Torre Latinoamericana is perhaps the only building in the historic district and the entire city that ceases to sink, and instead floats! Located on the corner of Madero and San Juan de Letrán, the building sits at the heart of history, culture, and ancient Aztec clay lakebeds. The Torre Latinoamericana was built between 1948 and 1956 and is one of the most important visual symbols of resilience and modernity in Mexico City today.

Purpose Construction projects have huge impacts on the social sustainability of the neighbouring community. The purpose of this paper is to identify and understand the key factors of a construction project that contribute to the social sustainability of a neighbourhood. Design/methodology/approach Questionnaire surveys relating to two case studies of regeneration projects in Saudi Arabia were carried out to ascertain and analyse the perceptions of residents of the neighbourhood communities in which the projects were built. Findings The results derived from factor analysis suggested five significant underlying social factors: health and physical comfort, accessibility, integration, economy and participation. These are defined as the core social functions necessary for enhancing social sustainability in the neighbourhood community as a result of new construction. Originality/value Ideally, a construction project will create spaces where people can interact socially, develop a sense of community and grow and prosper. This study reveals how the neighbours of the project felt about it and what sort of input they wanted to have in the design, construction and operation of the facility. For developers emphasising sustainability, this is the essential data.

Housing renovation, in contrast to new construction projects, has to take good care of the tenants who are already living in the building. What are the theoretical and practical implications concerning the transformation from a technology-and-engineering-focused renovation approach to a more user-oriented one? What are the mechanisms of strategy change? Based on our case we argue that the mechanisms of strategy change are based on the interplay between external disturbance and internal renewal. External disturbance is the trigger of strategy change, but it does not, in itself, necessarily lead to strategy change, and particularly not for an innovative new strategy. The internal new competence is the source of changing from an old strategy to an innovative new strategy. The real estate industry needs to undergo a transformation from the rationalistic technology- and engineering-focused renovation model (TEF model) to a more inclusive approach. We suggest a user-oriented model (UO model) where user involvement is seen as integrated in the whole process of renovation.

LEED-NC is a green building rating system for new construction developed by USGBC. Since it’s born in1998, LEED-NC has become the most famous green building rating system and made a big success in market expanding. Many other countries, including China, not only use experience of LEED-NC for reference to their own green building rating criterions construction, but also participate in the LEED-NC certification directly. But, as a green building rating system, one of it’s primary objective is to make clear what is the biggest problem in sustainable process. Since 1970’s oil crisis, resource shortage has become a common problem hindering the social and economic development of all countries and districts. Any green building rating system can’t avoid this reality. Using method of “example points+baseline point”, this article makes points statistics of “Energy & Atmosphere” category and it’s inner credits relevant to building energy saving. Finally, we verify LEED-NC’s performance in energy saving is not so good as people’s expectation. When using experience of LEED-NC for reference to our own green building rating criterion construction, we must be very cautiously. And when participating in LEED-NC certification directly, we must keep a conscious mind.

The Impact

Significance However, the COVID-19-related lockdown was a heavy blow, especially in the Buenos Aires Metropolitan Area (AMBA). Despite government support measures, the assistance has not offset the fall in sales, while those in the informal sector do not qualify for support. As a result, many retailers will not reopen and bankruptcies will rise. Impacts The number of retailers that close permanently will rise if relaxation measures are postponed, especially in the AMBA. The impact of the pandemic on shopping centres’ earnings will discourage new construction projects in the medium term. Retail recovery will depend on government’s ability to stabilise the economy following the successful foreign debt swap.
