Reduce Energy Consumption

Sustainable construction addresses both rising housing demand and the need to reduce energy consumption, but is not yet widespread in Vietnam, although the number of Green Building Certified projects has increased significantly since 2015, especially those with LEED certification. Certification adds value to the project but also incurs additional costs and implementation challenges for general contractors (GCs) and other stakeholders. The growing popularity of LEED buildings requires GCs to understand their role in fulfilling the LEED requirements. We therefore conducted a thorough review of the previous research on LEED v4 guidelines and their local equivalents to determine what is expected of GCs working on LEED v4 BD + C projects in Vietnam. A survey of 72 experts, engineers, and architects working in the construction sector identified the LEED tasks where Vietnamese GCs lack experience and suggested solutions to address this shortfall were developed. In particular, Vietnamese GCs lacked experience in implementing their sustainable roles. These results provide a useful foundation for Vietnamese GCs seeking to expand the scope of their LEED work and identified necessary training. Our findings will also guide future research to help GCs in Vietnam adapt to LEED’s sustainability requirements and support sustainable construction in Vietnam.

In this study, in order to evaluate the possibility of achieving the Net Zero Energy Building (NZEB) goal, the history of sustainable construction, and available green-rating systems with specific focus on Leadership in Energy & Environmental Design (LEED) rating system were explained. LEED rating system was selected as the most prevalent rating system in the industry to evaluate and analyze its efficiencies/drawbacks specifically in regards to the energy efficiency. The goal of this study is to answer an important question of the reasons to focus on NZEB concept when LEED rating has come up with a detailed certification process, which is somehow beneficial in regards to energy reduction. NZEB concept is defined as an evolution of very energy-efficient approach and it requires that the buildings have zero energy balance on an annual basis. This paper explains this questions in detail and it consists of three parts: in the first part sustainable building rating system including LEED certification is explained. The second part explains the deficiencies of LEED rating system in regards to the energy performance of buildings and the last part explains the NZEB concept and the movement towards the NZEB target.

The U.S. Green Building Council’s (USGBC) Leadership in Energy and Environmental Design (LEED) certification program supports sustainable construction as part of the effort to address climate change and resource depletion. It is the world’s most popular green building certification system, with more than 146,400 projects. Satisfying the LEED requirements brings many benefits to a project’s design performance and adds community value, but it does incur additional costs and challenges. This study examined the choices made by those working on the 222 LEED New Construction version 4 (LEED-NC-V4) projects that were certified between September 2014 and March 2020 to determine how the LEED project teams selected appropriate LEED goals. The results reveal interesting insights into the way project LEED goals and the credits corresponding to the target certification level were chosen, as well as the links and trade-offs between the various credit options. Based on these findings, useful suggestions are made for ways to help LEED project teams achieve their target certification levels and encourage authorities to continue to improve their local green regulations. The analysis of actual certified projects’ data makes it possible to re-evaluate the effects of newly updated requests in LEED v4 in the light of the stated goals of the USGBC.

Building Information

Design of green buildings involves specific processes compared to conventional construction projects that require participation of several disciplines. Having particular activities, functions, and physical aspects, green buildings impose their own difficulties during design. Building Information Modelling systems (BIM) use different software for virtual simulation of characteristics of projects, which promotes early detection of potential problems even before production of the intended design details. Implementing BIM technology in design stage, not only helps to minimize design problems, but also to shorten the stage itself. With this effect of BIM combined with sustainable practices and energy efficient technologies, design stage alone can be considered as a sustainable application of construction activities. Therefore, principles and requirements of green building certification systems can easily be performed for projects with capabilities of BIM technologies and tools. In this study, redesign of Yildiz Technical University, Faculty of Civil Engineering Building based on LEED certification system using BIM tools is presented. The project is prepared as part of a capstone project by senior civil engineering students. Design stages are planned to promote sustainability and qualify the requirements of LEED v3 BD+C (Schools). The main objective is to introduce the students to two major trends in construction industry (green buildings and BIM applications) and to create awareness of sustainable construction, green building certification systems and emerging technologies.

Construction Market

The construction industry, with its long supply chain and long lifetime of projects, is blamed to be one of the main contributors to environmental concerns including accelerated resource consumption and harmful emissions. Industry stakeholders, including developers, designers, contractors and suppliers, are, therefore, continuing to explore different options to reduce this impact. Various approaches have been adopted in different countries with building rating systems like the Leadership in Energy & Environmental Design (LEED) certification program being the most common way reflecting stakeholders’ efforts to go green. Governments and concerned authorities at national and state levels are expected to foster the trend of sustainable construction by motivating these stakeholders and pursuing policies that would help the green momentum. However, decision makers at such governmental and state levels face a challenge of prioritizing the policies and regulations that should be imposed. The objective of this paper is to present the development of a framework of an Agent Based Model (ABM) that simulates the effect of different possible policies in the construction market using Life Cycle Analysis (LCA), which is to be used by decision makers to assess and prioritize different policies or combination of policies. The framework was developed using Anylogic software and a sample construction market from the state of Qatar was used as an example for implementing the proposed framework. Results of running the model on this sample market illustrate the effectiveness of using this ABM as a support tool for decision makers in the area of sustainable construction.
