Abstract

This paper examines the factors affecting the implementation of green buildings for the local construction industry. Questionnaire surveys and structural interviews were conducted to investigate the economical and social factors in the implementation of green buildings. From the survey results, the industry strongly believes that green building implementation is environment-friendly and can improve social values to the consumers. However, material costs, construction and transportation for green materials and green building features are more expensive than those for the conventional buildings. Four major factors affecting the existing limited implementation of green buildings were also discussed. Recommendations to improve the implementation of green buildings were also explored. This study can bring insights locally and around the world on how green buildings can be implemented to achieve environment-friendly, long-term cost saving and being recognized by the society and the consumers to reduce difficulties and burden encountered in the implementation.

Highlights

  • Environmental protection is an important issue around the world

  • The reliability of the survey results is very high with the reliability in economic factor, social factor and overall of 0.934, 0.865 and 0.907 respectively

Summary

Introduction

Environmental protection is an important issue around the world. Comparing with other industries, the building sector generates a large amount of pollutants, including noise, air, solid waste, and water (Morledge and Jackson, 2001; Ball, 2002). The impacts of buildings on the surrounding environment over their entire life cycle process have been recognized as serious problems for the construction industry (Polster et al, 1996). Responsibilities for ensuring consistent construction activities and products with environmental policies need to be clearly defined, and effective environmental practices through waste reduction need to be promoted (Hong Kong Government - Environmental Protection Department, 2011). In Hong Kong and most of the other countries around the world, the building sector is one of the major contributors to environmental problems. Forty percent of waste reaching landfills was shown to be generated from the construction industry each year in Hong Kong (Hong Kong Government - Environmental Protection Department, 2011). The industry has been used to adopting non-environment-friendly practices such as the use of bamboo for scaffoldings, and non-inert materials for construction activities that would end up to landfills
