Motivators can be defined as specific catalysts that drive people to act in a certain way. These motivators are important for promoting green buildings and have a clear impact on decision-makers to adopt and implement the green building concept in architectural practice. This paper presents a comprehensive literature review to identify the important motivators for the adoption of green buildings among the stakeholders of the construction industry, the categorization and efficiency of green building motivators, and also the strategies for green building motivators.By reviewing 32 relevant studies conducted in different countries from 2008 to 2017, a total of 26 factors were identified as the main motivators to promote green buildings. These green building motivators were categorized into environmental, economic, and social motivators. With regard to efficiency, it was found that all green building motivators, whether environmental, economic or social are important for promoting green buildings and to determine a priority among these categories was not possible. The strategies for the adoption of green building motivators were also found. It is notable that the government has the greatest role to motivate stakeholders to adopt and implement the green building concept.The literature review of this study has a wide scope, covering most of the countries in the world, including developed and developing countries from the West to East. Hence, unlike most studies on the main issue of this paper that focus on a specific country or region, this in-depth research led to the development of a list of motivators for green buildings, derived from an extensive range of nations, which vary from environmental, economic, and social ISSN 2164-7682 2018 http://emsd.macrothink.org 138 aspects. This paper is expected to provide valuable information for decision-makers in the construction industry, namely, governmental authorities, design teams, and owners of projects regarding what motivate people to help further promote green buildings. The findings may also be useful for researchers to pursue further analyses on similar topics. Environmental Management and Sustainable Development

Aim of this study is to identify the important motivators of green design adoption in building projects of Libya. Green buildings are unpopular in Libya and are still in their early stages. This might be because of various reasons. Hence, this study focused on identifying major motivators of green design adoption. A total of 24 motivators identified from the literature review were investigated through questionnaire survey. Statistical analysis was carried for analysing 74 collected questionnaires sets with SPSS software Package. It is found that the 24 motivators considered in this study play an important role in pushing the adoption of green design in Libyan building projects. The results provide evidence that top five ranked motivators for green building adoption as ranked by the experts, include; control of climate change, providing improved comfort, health, and well-being of occupants, providing lower annual energy cost, increasing indoor air quality; and increasing indoor air quality; respectively. This study adopted a quantitative approach for collecting data. The targeted respondents were only within the capital Tripoli. As to the climatic change, global warming and lack of resources, the ‘green’ design issue has trended into a measurement in the construction industry. In Libya, rapid growth of developments has contributed significantly in greenhouse gases omission to environment. This has motivated the practitioners to adopt green design concept in building projects. This study has highlighted the key motivators of green design adoption in building industry of Libya which will enable the practitioner for moving forward to take advantage of those motivators for encourage the implement of green buildings. Finally, this study has suggested that international building standards and assessment tools should be adapted as guide to produce the laws and guidebook for green buildings practices in Libya.
