FY 2016 GHG Inventory Report for East Carolina University
The objective of this report is to assess the Greenhouse Gas (GHG) Inventory for the Main and Health Science Campuses of East Carolina University (ECU). The report presents a fiscal year (FY) 2016 GHG emissions inventory from direct and indirect activities of ECU. This is ECU’s second GHG inventory document, which builds on and compares to a baseline “Energy and Greenhouse Gas Emissions Report” prepared by SmithGroupJJR and RMF Engineering (January 2013). Based on energy use data from the 2011 calendar year, this report estimated the GHG emissions associated with the existing Main and Health Science Campuses, predicted the energy use of the proposed development based on current campus building standards, and demonstrated how sustainable design strategies applied to all new development and improvements made on the existing building stock could significantly reduce the carbon footprint of ECU. Results of this study are summarized in Figures 1 and 2 on the next page. We anticipate that the report will serve as a guideline for any committee or group aiming to reduce the emissions of ECU in the future. Understanding current GHG emissions is a necessary step towards developing strategies to lower future GHG emissions. For this study, fiscal year 2016 was selected as the temporal boundary with the goal of comparing results to the calendar year 2011 GHG inventory. There have been numerous changes in campus infrastructure over the years, with a potential to change source distribution and total amount of GHG emissions. For example, at the West Academic facility, two old chillers were replaced with a single, more efficient chiller with heat recovery capability. Combined with the addition of a heat exchanger between the new chiller and the existing propane-fueled boilers, this project resulted in more than a 70% reduction in propane use at the only ECU facility using propane for heat. Since the previous inventory only accounted for Scopes 1 and 2 of emission sources, it is difficult to draw a comparison in terms of the overall distribution of GHG emissions. However, when comparing the gross area of total building space and the emissions from just the first two scopes, the previous inventory concluded that ECU produces roughly 14.4 kg CO2e per square foot and the current inventory found a reduction of 0.15 kg CO2e per square foot of building. Of course, this is partly owed to the fact that gross area of total building space increased by nearly 600,000 square feet, from 6,220,312 square feet in calendar year 2011 to 6,804,178 square feet in fiscal year 2016. The biggest greenhouse gas emitting source for ECU still remains to be Scope 2 purchased electricity, which accounts for about half of all of the university’s emissions. Scope 1 emissions sources including On-Campus Stationary, Direct Transportation, Refrigerants, and Agriculture combined for a little more than 23% of total GHG emissions. Attributing nearly one third of the total GHG emissions, Scope 3 sources include Commuting, Directly Financed Travel, Solid Waste, Wastewater, Paper, and Scope 2 T&D Losses. Taking all three scopes into account, this GHG Inventory finds that ECU produced a total of 141,263.4 MT CO2e. A detailed breakdown of the results for this study will follow.
