Generation from PV

PurposePurposePurposePurposeTo create an effective tool that can be used to monitor energy and carbon reductions at Ithaca College

Acquire data and devise a method that could be used to assist with the effort to meet the President’s carbon neutrality goals

Test the tool, by using it to retroactively address the effectiveness of the energy efficiency measures implemented in 3 buildings on campus: CNS, the Campus Center, and the Hill Center

MERPMERP• Master Energy Reduction Plan

Tool to be used to plan out and gauge the effectiveness of our carbon reduction plan

Display real data on money invested, financial savings, and overall carbon reduction

FEATURES:

Payback periods on energy measures

Carbon reduction goals

Timeline for implementation

Room for future expansion, allowing for new technologies etc.

So far: our main carbon reductions have been due to: Energy Efficiency

So far: our main carbon reductions have been due to: Energy Efficiency

An increase in the efficiency of energy use for a building

Goal: to bring down the total energy use

Examples of efficiency measures:

Increasing insulation

Installing Compact Fluorescent lighting

Changing the way the HVAC systems work

Efficiency MeasuresEfficiency MeasuresEfficiency MeasuresEfficiency MeasuresIn 2004, Ithaca College contracted Clough-Harbor to recommend efficiency measures that could be done on campus

In addition to Clough-Harbor measures, Ithaca College did a few measures on its own

Campus Re-lamp

Temperature Set Points

Switch from electric to natural gas heat in gardens

Campus-wide electricity use 2004: 36.2 Million kWh/year

Campus-wide electricity use 2007: 29 Million kWh/year

The result was a massive 22% decrease in overall electricity use

Savings per year: $865,000

Fast Energy FactsFast Energy Facts

1000 kWh electricity used in the average American home each month

The average American home uses about 60 therms of natural gas each month

CNS uses an average of 215,000 kWh and 16,000 therms each month

Conclusions IConclusions I

• We have created an effective tool that can be used to monitor energy and carbon reductions at Ithaca College

• We have acquired data and devised a method that can be used to assist with the effort to meet the President’s carbon neutrality goals

• We have shown how to use the tool to examine the performance and recent carbon reductions at 3 buildings
