CO2e Reduction Strategies
● Commercial Energy – Benchmarking
● Transportation – Bus Rapid Transit
● Residential Energy – Solar Electricity Generation
![Page 11: MADISON COMMUNITY OPERATIONS CARBON INVENTORY 2012 Adam Anderson Tyler Brandt Iseul Choi](https://reader035.vdocuments.us/reader035/viewer/2022062422/568138e0550346895da09305/html5/thumbnails/11.jpg)
Commercial Building Energy Benchmarking
Requirement that owners of buildings with more than a specified amount of square footage must publicly report information regarding building energy consumption.
● Energy Star Portfolio Manager● 35,000 Buildings tracked from 2008 - 2011● 2.4% Annual reduction ● 7% total reduction over study period
● Study of California IOUs Program● 0.13 kWhs/square foot ● 0.002 therms/square foot

Residential: Solar Energy
● The City of Madison has been promoting solar technology at the local level since 2007
● MadiSUN program
![Page 16: MADISON COMMUNITY OPERATIONS CARBON INVENTORY 2012 Adam Anderson Tyler Brandt Iseul Choi](https://reader035.vdocuments.us/reader035/viewer/2022062422/568138e0550346895da09305/html5/thumbnails/16.jpg)
Forecasting Logistics
● Target 1 Megawatt by 2020 (Start year 2015)
● Average cost for installation $5.00/W
● $620,000 annual spending required for constructions through 2020
● Focusing on solar energy in residential sector (Using 2012 Residential price for electricity $.1188/kWh)
● Expecting 200 kW installed capacity will be annually deployed through 2020
