2014 Pathways to Sustainability - AECOM

AECOM was commissioned by Singapore’s Urban Redevelopment Authority (URA) for a sustainable development framework, planning and urban design for Marina Bay, the island’s new business and financial district, as well as the adjacent Greater Southern Waterfront.


Sustainable Redevelopment in the Pacific Rim: Taking a Cost-Effective, Multi-Systems Approach

Deanna Weber
Vice President

One of the most cost-effective ways to maximize sustainable performance in redevelopment sites is to integrate a whole systems approach to sustainability. Incorporating a detailed understanding of sustainability issues into the master planning process is fundamental to future project successes. Equally, a comprehensive framework of targets and monitoring indicators is essential for evaluating master plan designs and guiding future decisions. AECOM’s method for assessing and integrating sustainability in community development is developed through the Sustainable

Systems Integration ModelTM (SSIMTM); an integrated, multi-systems planning and economic evaluation tool developed by AECOM for multi-use projects. The results include a collaborative approach that integrates 1) best sustainability practices, 2) research-driven market parameters, 3) cost/benefit-driven implementation strategies, and 4) a dynamic urban design and place-making framework.

Integrated, whole-systems modeling has been applied by AECOM to a number of high-profile planning projects in the Pacific Rim including downtown Singapore’s Marina Bay, Oahu’s Kalaeloa Redevelopment, and relocation plans for the U.S. Marine Corps from Okinawa to Guam. The common thread in all of the redevelopment sites is leveraging multiple systems to achieve higher levels of sustainable performance in the most cost-effective manner possible. For example, on the Guam project, SSIMTM was used to compare sustainable systems and enabled decision makers to select a sustainability program that met all federal mandates for an increase in cost of less than two percent. This program allows the Marines to find the sweet spot in minimizing upfront costs and maximize savings in long term operating costs for energy, water, waste and transport.

In addition, the Marina Bay, Singapore site is designed to be a unique business and financial hub in a ‘city-in-a-garden’ setting. It will also be complemented by a full range of residential, shopping, dining, cultural, and entertainment facilities as part of a live-work-play environment. The increase in greenery has a major impact on the urban heat island effect and minimizes total building energy use.

Finally, on the Island of Oahu in Kalaeloa, a cost benefit tool was developed for the redevelopment site to phase timing of infrastructure in concert with land use types to minimize upfront development costs.
