INTRODUCTION Construction has a strong impact on the environment. [1] Thus, construction industry develops green

technology in construction of green building to minimize the impacts on the environment. Green technology refers to the technology that is considered environmentally friendly based on its production process, Will (2020). Meanwhile, green building focuses on increasing the efficiency of resources use in term of energy, water, and materials while reducing building impact on human health as well as environment during the building lifecycle Kartini (2020). The case study, which Sarawak, Malaysia, is in the midst in developing phase. Thus, in this phase, encouraging construction by green building technology will helps Malaysia which is one of the rapidest growing construction industries in the world achieve sustainable development. Major problems in Malaysia is construction practitioners has lack of knowledge or information regarding green building technology. This case study is limited to Kuching and Sibu areas only. In this case study, several buildings that implement green technology in Sarawak will be discussed. These buildings are Sarawak Energy Berhad (SEB) Tower, and University College of Technology Sarawak (UCTS). These buildings are certified Silver and Platinum GBI rating. The study regarding on these green buildings is done in order to satisfy the need of the study conducted which is in order to encourage construction’s practitioners to adapt green building technology in construction industry for sustainable development at developing cities in Malaysia. Green Building Index (GBI) evaluate the environmental design and performance of Malaysian buildings based on the following criteria which are energy efficiency, indoor environment quality, sustainable site planning and management, materials and resources, water efficiency and, innovation. [5] The purpose of the study is to encourage construction practitioners to adapt green building technology in construction industry. This study suggests several research objectives to be attained which are to promote the construction by green building technology in the country. Moreover, to raise awareness of the life cycle impacts of the built environment and its components amongst developers, contractors and as well as the public.

Both green buildings also implement water efficiency criteria which is by rainwater harvesting, water recycling and water – savings fittings. Moreover, both green buildings conduct a proper construction water management with storage, collection and recyclables and construction formworks and waste which allows both buildings gain marks in GBI rating, [7]. 3.2

CONCLUSION In conclusion, encouraging construction practitioners to adapt green building technology is by providing

better information on cost and benefits of green building technology. Sustainable construction incorporates elements of economic efficiency, environmental performance and social responsibility which contributes to architectural quality, technical innovation and transferability are included, Marcela (2015). To encourage all parties to get involves, the state government can provide the proper guidelines for green building for Sarawak construction's industry regarding this matter.
