Sustain Winona (a consortium of seven public private organizations committed to implementing sustainable environmental practices) had a goal of becoming an exemplar of Community Based Energy Development for the Nation.  They hired McKinstry to assist them in this endeavor.  McKinstry began by performing a carbon footprint for each of the seven members to establish a baseline.  After a baseline was established for each of the members, McKinstry identified several Facility Improvement Measures (FIM’s) that would help reduce each member’s carbon footprint through energy conservation and renewable energy opportunities. 

These measures included exterior and interior lighting upgrades; a comprehensive plumbing survey to ascertain which fixtures would benefit from water efficiency upgrades; retro-commissioning audits of various facilities; HVAC improvements; installation of vending misers; a renewable energy project which included capture and treatment of methane gas currently being flared, and the installation of a microturbine for the production of carbon neutral electricity and heat for the process boilers; replacing traffic signal bulbs with LED’s; the implementation of an energy awareness and education program for the public; the installation of LED parking lot fixtures; and control system modifications.

McKinstry utilized the Sustainability Energy Management Profiler (SEMP), to analyze FIM’s for implementation taking into account those which would provide the best synergy to provide the greatest return on investment for Sustain Winona members.  McKinstry has already completed a Phase 1 project with the City (Central Garage HVAC and library lighting project) and is currently working on a Phase 2 project with the City and a Phase 1 project with Winona County.  They are also in the process of developing projects with several other Sustain Winona members.
