Calculating Energy Savings

On Friday, I presented a brown bag lunch presentation on Calculating Energy Savings to the OFS staff. The presentation started with a look at some spreadsheets I'd created to quickly calculate the savings from two easy energy retrofits... reduced pressure drop air filters and premium efficiency motors. The Excel file had pages started for calculating a number of other types of savings, but wasn't quite ready to share at this time. Next we went over part of the attached Power Point starting with how to calculate lighting fixture requirement using the Lumen Method (the agenda on the second page of the presentation was never changed to represent the actual presentation). We then went over the Fundamental Law of Illumination and how fixture distance affects illuminance. The presentation continued with an explanation of energy models and how they work. We then finished by looking at an eQUEST version 3.62 model for one of the undergraduate houses and quickly reviewing some of the inputs and summary reports. About 6 people attended.
