22. CHALLENGES & OPPORTUNITIES – ENERGY CONSERVATION Principal Agent Problem Majority of campus departments are not responsible for utility costs Limited metering creates a cost barrier for tracking and reporting energy use Budget Most departments are faced with cuts of 3% to 10% for the near future Ongoing utility deficit Project - Based Funding Funding based on individual projects limits development of long term resources for ongoing energy conservation programs such as integrated approaches with an occupant component Credit for Energy Efficient Practices Allow departments to count reductions in their energy use as part of their budget cuts CO 2 Reduction Program Funding Create a project-independent funding source with the annual amount based on the campus emissions total multiplied by the current market cost of high-standard carbon offsets
