Steam Trap SurveyCentral Distribution and Building Systems

• 934 Steam Traps Surveyed across Campus• 133 Failed Traps (14% of those surveyed)• Steam Traps Tagged and Logged into FME

Database• Failed Traps = >$200,000 yearly Energy Loss

5

• $200,000 Yearly Energy Loss• Estimated Total Cost of Survey and Repair: <$60,000• ROI in >4 Months from

Date of Repair• Goal is to Keep Campus-wide

Failure Rate to <3%

• Next Step is to Survey andEvaluate all Campus Steam Traps

U.S. EPA Energy StarNational Building Competition

• Energy Star National Building Competition, cont.– Energy Star Website: www.energystar.gov/buildingcompetition– Twitter Feed for the Competition– Competition thru October 2010– 14 Buildings in Competition,

including Morrison Residence

Hall from UNC-Chapel Hill– Student Participation to Create

Energy Videos for Website– Tucker will receive Energy Star certification.

Energy Policy Act (EPACT) of 2005Tax Deductions Assignable to Designers

• EPA-2005 provides an Assignable Tax Deduction that can be “sold” to Designer for additional scope items or reduction in fees

• Designer defined as “architect, engineer, contractor, environmental consultant or energy services provider”

• Tax Deduction based upon energy savings and affected square footage up to $1.80/sf– $0.60/sf each for Lighting Systems, HVAC Systems and Building

Envelope

• Proposed Legislation increases credit to $1.00/sf/system

Building Energy AuditsProgress Energy/MAE Programs

• Energy Management Staff has performed Energy Audits to evaluate energy use and applicability to Progress Energy’s Energy Efficiency for Business Program

• Audits Performed on:– Flex Lab Building– Method Road Greenhouses– Materials Storage Warehouse

• Energy Management applied a no-cost ECM applied to manage Metal Halide lamp use saves >$1,600 per year

• Initial Cost and ROI to be determined based upon energy savings and PEC Rebates

Energy Fellowship Grant ProposalState Energy Office / ARRA Funding

• NCSU Energy Management led team to submit a $500 k grant proposal to the SEO for 6 full-time two-year fellowships

• Team Members:– NCSU Energy Management– NCSU Sustainability Office– NCSU FREEDM Systems Center– NCSU Solar Center– Advanced Energy

• Fellows will work on Synergy Projects among Teams

12

Energy Efficiency Block Grant AwardUNC-GA/ State Energy Office/ ARRA Funds

• SEO and UNC-GA requested proposals from Constituent Universities for Energy Efficiency Projects– Threshold for savings is to reduce energy used by 15 million BTUs for

each $1,000 spent

• Facilities Division prioritized a list of four projects:– Campus-wide Lighting and Controls Retrofit– Retro Commissioning and Electrical Equipment at the Flex Lab

Building– Replace two 130 ton chillers at Research Building II

– NCSU has been awarded $778 k to complete the projects by Dec 2011.

Student Sustainability Attitude Survey - Findings and Results

85% of the student sample think that it is important for NC State to be a leader in sustainability and the environment.

86% of the student sample think that it is important for Americans to conserve personal use of energy.

Over 85% of the NC State student sample think that it is important to recycle the products they use.

76% of the student sample agree with the statement, “When I conserve energy, I contribute fewer greenhouse gases to the atmosphere.”

68% of the student sample think global climate change will be a major problem for future generations.
