Commitments to Conserve

NC Session Law 546 (SB 668) – 2007“The energy consumption …shall be reduced by twenty percent (20%) by 2010 and thirty percent (30%) by 2015…”

Climate Neutrality by mid century

Coal free by 2020

Current Focus:Energy Conservation Measures (ECM) projectLighting upgradesEducation and Awareness

Energy Conservation Measure (ECM) Project

Cornerstone is the UNC Energy Use PolicyTemperature StandardsOccupancy SchedulesPurchasing PolicyEfficient Construction PracticesCampus Community Involvement

Project started mid-July 2009

Initial projections:$4.8M avoided costs53,400 metric tons CO2 equivalent reduction5500 hrs labor and $150,000 implementation costs

Energy Conservation Measure (ECM) Project

Seven prescriptive measures

Occupancy Scheduling & temperature standards (2 ECMs)

Building system tuning and enhancements (4 ECMs)

Education and Awareness (1 ECM)

ECM Project Results to Date

$3,227,870 avoided utility costs

327,011 MMBtu Energy Savings

39,764 MTCDE savings

22,088,279 gallons of condenser water saved

$206,489 project cost9,351 hours to implement

Sustaining the Gain

Fix it DON’T forget it

Making conservation a core UNC valueContinued senior management

supportMake conservation relevant to all

Energy Management Tomorrow

Types of projects we plan to be involved in:

ECM program

Energy Savings Performance Contracting (ESPC)

Lab airflow optimization

Lighting upgrades

Education and Awareness

Energy Management TomorrowEducation and Awareness

a. Inform (Dashboard)i. Provide energy information for students, faculty, staff for

reinforcement of conservation related behaviorii. Provide information for engineers, analysts and technicians and for

software based statistical analysis.

b. Educate on how to affect consumptioni. Enhance existing programs (RESPC, Green Games, etc)ii. Provide training to Facilities Services HVAC, plumbers, and

electriciansiii. Provide training to building managers

c. Incentivize different behaviori. Implement reward program for measured energy savings by

individual or group
