Sustainable Campus Improvement Program Design using Energy Efficiency and Conservation
Faghihi, V.; Hessami, A. and Ford, D.
Reducing energy consumption is critical to improving the sustainability of built infrastructures. Both increased efficiency and conservation by users can contribute. This work investigates feedback in the design of energy improvement programs that exploit efficiency and conservation by developing a system dynamics model. The model formalizes the paid-from-savings approach and is validated using a sustainability program at a major university. Model simulations investigate the impacts of five program designs on two forms of performance measure (energy savings and monetary savings) and capital requirements. Results reveal the importance of both the timing and relative strength of two critical reinforcing feedback loops. Results recommend the consideration of the integrated use of conservation and efficiency under capital constraints. This result suggests a generic pair of linked reinforcing loops and their staged activation as an advanced solution to the dynamic challenges of sustainable improvement program design.
