The Impact

Green buildings refer to buildings that decrease adverse environmental effects and maintain natural resources. They can diminish energy consumption, greenhouse gas emissions, the usage of non-renewable materials, water consumption, and waste generation while improving occupants’ health and well-being. As such, several rating tools and benchmarks have been developed worldwide to assess green building performance (GBP), including the Building Research Establishment Environmental Assessment Method (BREEAM) in the United Kingdom, German Sustainable Building Council (DGNB), Leadership in Energy and Environmental Design (LEED) in the United States and Canada, Comprehensive Assessment System for Built Environment Efficiency (CASBEE) in Japan, Green Star in Australia, Green Mark in Singapore, and Green Building Index in Malaysia. Energy management (EM) during building operation could also improve GBP. One of the best approaches to evaluating the impact of EM on GBP is by using structural equation modelling (SEM). SEM is a commanding statistical method to model testing. One of the most used SEM variance-based approaches is partial least squares (PLS), which can be implemented in the SmartPLS application. PLS-SEM uses path coefficients to determine the strength and significance of the hypothesised relationships between the latent constructs.

Envelope Material

The increasing need for eco-friendly green building and creative passive design technology in response to climatic change and global warming issues will continue. However, the need to preserve and sustain the natural environment is also crucial. A building envelope plays a pivotal role in areas where the greatest heat and energy loss often occur. Investment for the passive design aspect of building envelopes is essential to address CO 2 emission. This research aims to explore the suitability of using integral-monolithic structural insulation fibre-reinforced lightweight aggregate concrete (LWAC) without additional insulation as a building envelope material in a high-rise residential building in the different climatic zones of the world. Polypropylene and steel fibres in different dosages were used in a structural grade expanded clay lightweight aggregate concrete. Physical and thermal properties of fibre reinforced structural LWAC, normal weight concrete (NWC) and bricks were measured in the lab. The Autodesk@Revit-GBS simulation program was implemented to simulate the energy consumption of a 29-storey residential building with shear wall structural system using the proposed fibre-reinforced LWAC materials. Results showed that energy savings between 3.2% and 14.8% were incurred in buildings using the fibre-reinforced LWAC across various climatic regions as compared with traditional NWC and sand-cement brick and clay brick walls. In conclusion, fibre-reinforced LWAC in hot-humid tropical and temperate Mediterranean climates meet the certified Green Building Index (GBI) requirements of less than 150 kW∙h∙m−2. However, in extreme climatic conditions of sub-arctic and hot semi-arid desert climates, a thicker wall or additional insulation is required to meet the certified green building requirements. Hence, the energy-saving measure is influenced largely by the use of fibre-reinforced LWAC as a building envelope material rather than because of building orientation.

Waste Management Practices

Hong Kong is a densely populated city with high-rise developments, and as in other metropolitan cities, the amount of waste generated from construction projects in the city is increasing annually. The capacity of existing landfills is expected to be saturated by the 2020s. Construction waste management has been implemented for years but the performance is still not satisfactory. The aim of this research paper is to explore and formulate strategies and measures for effective construction waste management and reduction in highly urbanized cities such as Hong Kong. A desktop study on construction waste management practices was carried out for a preliminary understanding of the current situation in Hong Kong. Semistructured interviews and focus group meetings were further conducted to shed light on how to improve construction waste reduction and management in Hong Kong. The main contributions of this research study are the potential short-term, medium-term, and long-term strategies, which are related to the design stage, tender stage, construction stage, and government support. The five major strategies recommended are financial benefits to stakeholders, public policies in facilitating waste sorting, government supports for the green building industry, development of a mature recycling market, and education and research in construction waste minimization and management.

Method Approach

Purpose An understanding about the criteria determining the successful application of green features, and the barriers to implementation is essential in order to promote and enhance green building development. The purpose of this paper is twofold: first, the criteria determining the success of GBFs; and second, the barriers to implementing GBFs in Hong Kong. Design/methodology/approach A multi-method approach comprising a comprehensive questionnaire survey and a semi-structured group discussion with construction professionals, along with three case studies was adopted to address these two issues. Findings Findings suggest that although environmental performance is the most significant criterion, the living quality of occupants and the costs of green features play a crucial role in determining the success of their application. However, the environmental aspects of buildings are not sufficient for rating or determining the greenness level of a building. As for barriers, the green cost implications; the structural unsuitability of the current stock of old buildings; and the lack of financial incentives were found to be crucial barriers preventing the application of green features in the Hong Kong building sector. Originality/value GBFs have received extensive attentions by the academia and industry. This paper used a mix method approach by exploring success criteria and barriers to implementing green features in the building sector in Hong Kong. As green building development is still a contemporary subject of discussion, this study would be beneficial to decision makers as it identifies the criteria determining the success of green building adoption and barriers to implementation of such features. Hence, relevant stakeholders will have better understanding of the factors affecting the adoption of GBFs.

Suitable System

Construction is one of industries that have negative impacts on the environment. Relevant organizations both in Thailand and other countries have been trying to minimize these impacts. Developing green building assessment systems is one of efforts in reducing environmental impacts and using natural resources efficiently. Currently, there are many green building assessment systems with different objectives and assessment scopes in some details. This could cause some confusion in selecting the suitable system for the project in accordance with its environmental, social and economical contexts. This study was aimed to compare and provide overview and components of these systems. The comparison results can be used as a guideline for further development of green building assessment systems. It is found that most major green building assessment systems still concern only environmental issues while newly developed systems have included social and economic issues in their criteria. Furthermore, the system which is developed in one environment could not be used with full capabilities in another. This will lead to more research in developing the assessment system that is more comprehensive and adaptable enough to be used effectively in various environment.

Promoting green building has become an important policy goal in Taiwan. This paper explores the possibilities of transforming a regular duplex housing unit into a green building. Through an examination of residents’ demand of a selected housing community in Tainan, Taiwan, the demand of green building facilities and services by actual users was identified. This was followed by a design approach which applies several selected green building technologies based on the demand of residents and local environmental characteristics. The result shows that multi-dimensional goals of transforming existing housing into a green building can be obtained through a well-planned design approach which better understands the demand of residents.
