BACKGROUND NCSU Facts: Since 2002-2003 Fiscal Year Reduced 10% in energy consumption Increased 21% in total utility costs

Slide 4

BACKGROUND 2009 Added over 1.6 million GSF to campus Increased 6% in total GSF 2009-2010 Fiscal Year Consumed 2,250,610 million BTU of energy Consumed 475,400 CCF of water Total Energy and Water Cost: $32 million

Slide 5

SUSTAINABILITY Foundation for Advancing Sustainability: A Strategic Plan for NC State University 1.Achieve 30% reduction in building energy consumption by 2015 . 5.Ensure cost effective & reliable energy supply

Slide 6

SUSTAINABILITY Solar Thermal System

Slide 7

SUSTAINABILITY Solar Projects on campus: Carter-Finley Solar Photovoltaic (PV) Completed 2008 75 kW Solar Collectors Carolina Solar, Owner Carmichael Solar Thermal Completed 2011 142 total Solar Thermal Collectors $11,500 savings per year

Slide 8

SUSTAINABILITY 31.4% of energy related to water heating Lodging in dorms Over $1.2 million/year on water heating

Slide 9

SUSTAINABILITY Current Solar Projects not enough Expansion of Solar Projects to Residence Halls Increase energy savings & reduce utility costs Method of Green Education for students 20 Residence Halls housing 6,592 students Minimal tree cover Durable, Sustainable, Economical

Slide 10

SUSTAINABILITY Current Applications University of San Francisco Installation of 72 solar thermal panels Heats 13,000 gallons of water for 3 dorms UNC Chapel Hill Morrison Hall 176 solar thermal panels Dropped energy usage by 36% in one year

Slide 11

IMPLEMENTATION General Statute 143-64.12(a) NC Legislature passed August 2011 Mandates UNC system schools 100% of savings ECMs returned to utility budget 75% of savings dedicated to fund future ECMs

Slide 12

SOLUTION Solar Thermal Panels Dorms with optimal sun exposure Sullivan Residence Hall Roof Size: 16200 ft 2 Lee Residence Hall Roof Size: 36000 ft 2 Collection of water data & sun exposure 21 August 2013 10 May 2014

Slide 13

SOLUTION Fairly simple installation Bracket-mounted panels on roof Panels linked to main control system Control system linked with tank Determines when to use solar energy

Slide 14

SOLUTION Future topics of Discussion: Based upon empirical & actual data: Volume of water heated due to sun exposure Current vs. required water holding tank capacity Peak hours of water usage Comparison of different solar panel brands Effectiveness Ease of installation Cost
