Consilience: The Blog consists of a place where sustainable development professionals (defined for our purposes as architects, engineers, land-use planners, landscape architects, appraisers, accountants, attorneys, and include those in leadership CSR capacities) and their educators make real-world contributions to the built environment. A best-practice example of consilience within this community is the use of Integrated Project Delivery, a collaborative interdisciplinary process using such tools as Building Information Modeling during the project’s life-cycle from conception, to construction, operation, and concluding with re-use or redevelopment.
