Sustainable INFRASTAR

General Overview

Infrastructure asset development has huge impact on social, environment and economy. Therefore, it is critical for any infrastructure project to balance economic, social an environment sustainability factors in its development. The need for a more standardized method or tool to appraise the sustainability of such development is becoming more essential.

What is Sustainable INFRASTAR

Sustainable INFRASTAR stands for Sustainable Infrastructure Rating Tool where it applies an objective & evidence-based rating system that assess each of the identified key conditions, including:

  1. Land use planning and management
  2. Resource Management
  3. Energy and Water Management
  4. Biodiversity and other ecosystem services
  5. Social and cultural protection
  6. Stakeholder coordination

Main objectives from Sustainable INFRASTAR

  • To create a continuous awareness on the importance of sustainability throughout the pre-commissioning stages of infrastructure projects
  • To prioritise significant environmental and social attributes for sustainable infrastructure as early as the conceptual stage
  • To convey an improved performance related to environmental and social through project design and construction
  • To recognise and reward efforts made by projects towards achieving an exceptional level of sustainable infrastructure
  • To ensure the implementation of environmental and social best practices are in accordance to the standards adopted locally and globally
  • To measure the level of sustainability of infrastructure projects

The Malaysian Construction Industry Development Board (CIDB) has developed a sustainable infrastructure rating tool for Malaysia with an ultimate purpose to assess the extent of sustainability measures adopted by infrastructure projects in Malaysia primarily at both design and construction stages. Sustainable INFRASTAR acts as a design and measurement tool to ensure consideration and sustainable elements are incorporated early in the development of project.

Assessment takes place at two project stages; namely design and construction:

Classification for Infrastar


A certified assessment that achieves 40% and above credit percentage will be awarded with a-star rating. The classifications of assessment points with their respective ratings are as follows:
