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
