The Institute for Sustainable Infrastructure continues to develop and refine the Envision rating system.  Part of the refinement includes the development of the development of a business case evaluator tool.  ISI is seeking feedback on an Envision economic companion tool for stormwater.

 

Economic factors are an essential component of sustainable infrastructure, along with environmental and social considerations. The business case for sustainable infrastructure goes beyond a return on investment: it also includes infrastructure effectiveness, costs, reliability, and livability. These factors contribute to how communities perceive these infrastructure projects which in turn has a real dollar value associated with it.

 

This Envision Economic tool, called the Business Case Evaluator, is being developed by Impact Infrastructure, LLC, which is a Charter Member of ISI. The Business Case Evaluator (BCE) provides a value-based and risk-adjusted analysis of stormwater infrastructure projects and maps these to the Envision credits. Once it is finalized based on public input, the BCE will be offered at no cost through the ISI website.

 

There are several economic tools that are being developed in parallel in different agencies, companies, and research organizations that fill the unique needs of different infrastructure sectors and geographic locations. ISI encourages the development of these tools and will continue to provide an opportunity for public feedback to strengthen the metrics and tools that will be made publically available.

 

The Business Case Evaluator for Stormwater Management, user manual and documentation can be found at sustainableinfrastructure.org/tools/stormwater/index.cfm.

The Institute for Sustainable Infrastructure (ISI) has recognized the City of Karachi, Pakistan for its use of the Envision™ Rating System to plan a new suburb of 200,000 people. The suburb, which is currently under construction, uses Envision as a template for weaving together several different kinds of infrastructure into a single community sustainability profile.

In formally recognizing the project, DHA City Karachi (DCK), in a ceremony in Washington, D.C., ISI President and CEO William Bertera noted that this is the first known application of the Envision tool to a whole city, and that the result speaks highly of Pakistan’s commitment to sustainability.

 

Leading the workshop, which described the project in detail, were lead consultants Inam Ahmed Osmani, Chairman of Osmani & Company, Arif Osmani, Project Team Leader and Brig. (Retired) Muhammad Rafique, the Project Director representing the DHA City of Karachi. Professor Spiro Pollalis of Harvard University and a key resource for the project, shared his experience with sustainable cities generally, with specific reference to the Karachi project. Also present were dignitaries from the Pakistan Embassy and Karachi community leaders.

The project itself has been designed from the ground up. The design of the community, which is intended to be the first of several, takes advantage of the latest technologies for heating, cooling, managing wastes, transportation, water and energy use, each of which was modeled before construction began.
