The Green Building Index (GBI) is Malaysia’s recognized green rating system to promote sustainability in the built environment and raise awareness about environmental issues and responsibility to future generations. The tool provides an opportunity for project developers and owners to improve green design and construction. The GBI assessment for townships assesses infrastructure projects’ sustainability at the scale of communities or small neighbourhoods. The evaluation process consists of a Planning Assessment, a Final Planning Assessment, resulting in a pre-certification, and a Completion & Verification Assessment, resulting in a final certification. To maintain the certification, reassessments are required every three years.

Envision is a flexible system of criteria and performance objectives to aid decision makers and help project teams identify sustainable approaches during planning, design and construction of infrastructure projects that will continue throughout the project’s operations and maintenance and end-of-life phases. The Envision system consists of different components: (1) The Envision Pre-Assessment Checklist can be applied early-phase and used to prepare later sustainability assessments; (2) the Envision Online Scoresheet provides for a detailed online self-assessment; (3) the Envision Verification provides for an independent third-party project review process; (4) the Envision Awards offer recognition for qualifying verified projects.

CEEQUAL Projects assists in delivering improved sustainability performance and strategy of infrastructure projects. Projects are assessed across a range of management, environmental and social criteria, using the CEEQUAL Online Assessment Tool. The individual version for Term Contracts has been specifically created for the sustainability assessment of civil engineering and public realm works that are undertaken through contracts over several years, offering two question sets, one for maintenance works and one for new works. Assessments are conducted by CEEQUAL-trained assessors and verified by CEEQUAL-appointed external verifiers (in case of Term Contracts in the first and penultimate years including yearly surveillance visits).
