OP-16: Life Cycle Cost Analysis
Environmental Sustainability Director
Office of the Executive Vice President
Does the the institution employ Life Cycle Cost Analysis (LCCA) as a matter of policy and practice when evaluating energy and water-using products and systems?:
Does the institution employ LCCA as a matter of policy and practice across the operations of the entire institution (i.e. all divisions)?:
A brief description of the LCCA policy(ies) and practice(s):
Consultants, vendors, and contractors responsible for projects at Duke must adhere to all applicable building codes and the Duke University Construction Standards. As such all consultants, service providers, vendors and contractors are to follow all applicable building codes and Duke University Design Guidelines. Part of the standards includes Duke's LEED Plus policy, a guideline for architecture, engineering, and construction teams working for Duke, addressing energy and water efficiency goals for building projects. This policy reinforces the 2007 Duke Climate Action Plan.
Extract from policy:
A/E/C Teams must demonstrate a 30% improvement over energy efficiency baseline of ASHRAE 90.1-2007, Appendix G, through the development of an accurate Whole Building Energy Simulation Model. The choice of software is left to the modeler; however, DOE 2.x- or EnergyPlus-based systems are recommended.
The accuracy of the model is critical to prediction and budgeting for the life cycle cost of our buildings. Additionally, an accurate WBES will aid in maximizing available LEED credits, and the selected credits are meant to ensure accuracy of the model. To encourage the effort and to ease communication, the modeler should use the attached forms for identifying modeling input and output values for Duke review.
A/E/C teams should produce early model iterations at the Design Development Phase for review with Duke Facilities Management staff (see attached for requested format). Teams must submit a finalized model and Life Cycle Cost Analysis to FMD as part of the Construction Document package. The WBES model results are considered integral to the 100% CD submission, and are required for FMD to sign off on construction approval.
During the construction phase of the project, all submittals are required to include an energy and water impact statement, identifying if the proposed equipment will change building energy consumption, and if so, by what value.

Duke also has adopted an extensive Green Purchasing Policy with additional sustainability guidelines for the campus.
