Goal: Implement compact, sustainable cities in Asia that are ecological, livable, and smart

Positioning: To serve as a key proponent for the development of compact, low carbon cities in Asia using a holistic and integrated urban management approach

Principle: Employ a multi-disciplinary, multi-sectoral approach to every stage of a city’s

development cycle

Tool: Sustainable System Integration Model (SSIM)

• Fully leverage AECOM’s professional experience in planning, design, economy, energy, transportation, ecology, environment,

water management, green construction and other fields

• Committed to the concept of sustainable development

• Participate in the entire life cycle of urban and land development, from planning to implementation, monitoring, management

and continuous optimization

What is the Sustainable Systems Integration MethodTM (SSIMTM)?

• SSIMTM is a decision support

method/tool for clients

• SSIMTM is an integrated, whole

systems approach to planning,

design and engineering

• Systems are optimized from a

cost/benefit perspective to

target the “biggest bang for your

buck”

• SSIMTM has been extensively

used on private sector, public

sector and federal applications
