1. THE NELSON INSTITUTE CARBON FOOTPRINT PROJECT 2006-07 AASHE Conference November 11, 2008 Damon Clark Summit Blue Consulting Jeannette LeBoyer Econergy International Consulting

2. Introduction Goals – Provide a preliminary metric of carbon dioxide equivalent expended by the Nelson Institute using the Clean Air Cool Planet Campus Carbon Calculator – Outline our methodology so it can be reproduced on a larger scale – Provide a qualitative analysis of current core faculty energy use – Detail the limitations of our analysis, so that groups can supplement this preliminary analysis in the future. Why is this project relevant?

4. Data Collection  Gathered information from the following sources:  Facility Plant Managers Electricity Use Steamed Heat  Nelson Institute Staff

5. Energy Use Sectors  Electricity – Total for Prorated Square Footage: 368,093 kWh  Steamed Heat- Cogen Facility, West Plant (Walnut St) and South Plant (Charter St)  Steam Heat: 11,099 MMBtus  Chilled Water: 3.49 MMBtus  Personnel Impacts  Transportation
