Extensive governmental and industry efforts have been devoted to developing innovative housebuilding systems. However, it appears a challenge for housebuilding firms to move beyond their demonstration status and get their housing system adopted at a large scale and over a longer period. This is problematic since worsening developments concerning the environmental impact, poor production efficiency and a lack of client orientation of traditional building practices remains unsolved. This article describes a multiple case study on the continued adoption of innovative industrial housing systems. The multiple case study centres around a housing system which is generally considered as a rare example of an industrial housing system that has succeeded in the last 30 years in maintaining a leading position in the Dutch housing sector. This article analyses the reasons for this continued adoption in contrast to three industrial housing systems which had to abandon the market. The case study findings show that at least five mechanisms play a determining role in the eventual continued adoption: the regional presence of the builder; the builders’ operational excellence; a natural fit with existing technology standards; a competitive added value, and; the ability of the house-builder to keep pace with changing market requirements. An important lesson from this study is that, for continued adoption, one needs to stay alert and adapt the housing system to changing market requirements.

Global warming and changing climatic conditions, as well as over-consumption of energy resources have led to the discussion of sustainable and energy-efficient approaches. The buildings have one of the most significant roles in over-energy consumption causing various global effects. Therefore, the importance of developing energy-efficient and energy-retrofit strategies in buildings has been increasing day by day. This study aims to introduce a sustainable lighting system design approach for new and refurbished buildings in terms of visual comfort and energy performance in accordance with the current standards. “TS EN 12464-1:2013 Light and lighting- Lighting of workplaces- Part 1: Indoor workplaces”, which describes basic requirements for visual comfort and “TS EN 15193-1:2017 Energy Performance in Buildings - Energy requirements for lighting-Part 1: Specifications”, which introduces a renewed and updated methodology to estimate lighting energy performance in buildings are used as the metrics for the approach offering to design sustainable lighting system. Office space for two people is selected as a sample in order to apply the developed approach. Obtaining results demonstrate that the lighting-retrofit design strategies have a great positive impact on visual comfort conditions and energy consumption in the office buildings, where energy use for lighting accounts for a huge proportion of the total energy consumption as well as providing visual comfort conditions is very important

Especially after the 1980s, computer-aided design programs paved the way for the implementation of unusual forms and building structures in the construction industry. This situation has increased the necessity of process management and the development of existing systems in the field of construction project management has become a necessity. As a result of these developments, the concept of integrated project management (IPD), which aims to increase the coordination, cooperation, and communication among the team members of different disciplines, has emerged. In addition to the coordinated work of the design team; project stakeholders such as customers, contractors, and subcontractors are also directly involved in the process. In such large-scale projects, the concept of the Great Chamber, an integrated project management system, emerged as a collaboration platform in project management. As a result of the search for process management, the Big Room concept, which aims to increase the coordination, cooperation and communication among the team members of different disciplines, is a physical space organization that uses technology but has central human and human relations. Big Room is a design and coordination office located on the construction sites. In this office, all stakeholders are involved early on and are directly involved in the management and control of a project. Team members work together to improve team performance, interact and accelerate decision-making and reduce project costs for better communication. In this study, it is aimed to introduce, search and determine the advantages of Big Room concept which is used in many big projects in the world by searching literature.

Being one of the primary contributors to global GHG emissions, the construction industry has been the focus of many recent studies. The process of manufacturing and transporting of building materials, and installing and constructing of buildings consumes great energy and emits a large quantity of greenhouse gas. The concern for GHG emissions in building construction in Bangladesh is not satisfactory. This study identifies the sources of GHG emissions during building construction phase and estimates the GHG emissions from those sources for a case building in Bangladesh, following the process-based methodology. The results for the case building show that about 98.38% of total emissions are due to the manufacture and transportation of building materials, 1.31% is due to energy consumption during the construction period and only 0.31% are due to waste disposals, while concrete and brick-works are the most contributing materials to the GHG emissions, about 35.22% and 48.67% respectively. This study also proposes a set of strategies, for example, using recycled building materials, especially recycled steel, as well as, transporting building materials by sea, re-using wooden waste materials and using hardwood plywood in place of non-load bearing brick walls that can help to reduce GHG emissions.

Construction and demolition waste (CDW) is one of the major environmental problems, and thus, should be considered as a significant component of sustainable built environment. In theory, there are three main options to overcome the CDW generation problem such as reducing, reusing, and recycling. However, in practice, it is a general behavior to implement the first two options to deal with CDW in many developing countries such as Turkey. The main reason behind this may be the high initial investment cost and compelling regulations concerning CDW recycling plants. Hence, sorting at source and reusing activities for CDW emerge as two beneficial alternatives for the Turkish construction industry. Based on these aforementioned arguments, the objective of the current study was to identify and examine the specific perspective of construction firms about sorting at source and reusing activities in the Turkish construction industry. Toward this aim, a questionnaire survey was applied to construction professionals in Turkey. According to the findings, for Turkish construction firms, having a CDW management plan is not common, using landfills to dispose the waste generated is popular, accessing to CDW recycling plants is very limited, sorting at source practices are rare, and sorting CDW in separate containers is not preferred. However, construction professionals have positive approach on sorting at source, reusing, and recycling of the CDW and excavation soil, and the selective demolition method before recycling. In addition, the financial and physical support of local authorities seem to be important for dissemination of CDW management applications in Turkey.
