NEXT 40 YEARS - CLIMATE NEUTRALITY

2008 Greenhouse Gas Inventory

HOW NC STATE COMPARES

Impact of Near Term Strategies 20% GHG reduction in 2015

5/17/2015 Energy Key Performance Indicator: BTUs/GSF

2015 Goal = 30% reduction of energy use compared to 2003 ENERGY CONSERVATION 2015 Goal

PYRAMID OF CONSERVATION THE POWER OF ONE Diagram: Minnesota Power: If behavior change can account for 5% of electricity reduction, how much $ will NC State save?

Why solar? Student demand Research opportunities Public perception Clean, renewable energy Climate Action Plan

Why not solar? High relative cost for carbon reduction Efficiency first Perception: New technology Perception: Onerous process

The Solar Path Use this procedure when a viable project is identified Contains many of the forms needed Very similar across state funded organizations

Intern Project: Site Suitability Survey Description of the project

10 criteria Impediments Orientation Pitch Visibility Shade Rooftop Access Roof Install Date Roof Type Roof Area BTUs/ GSF

Impediments Any object on the roof that impedes placement of a solar array either through Physical presence Casting of a shadow

High Impediments - Dabney 50%< Roof Impeded

Low Impediments - Witherspoon 25%> Roof Impeded

Orientation Determined along the long axis of the building Ideal Orientation is E-W

Carmichael gymnasium N

Visibility Determined by Walk-By Site Assessment Low = >25% of roof visible Medium = 25% - 75% of roof visible High = > 75% of roof visible

Low Visibility - Dabney

High visibility - Jw isenhour tennis center

Shading Extent to which objects cast a shadow on rooftops Low: >25% Shaded Medium: 25% - 75% Shaded High: <75% Shaded

High shading - Turner House

Low Shading - Centennial sub station

Rooftop Access Availability of perimeter space for crane use Low: If materials can’t be stored on roof or no reasonable crane access Medium: 1-2 sides available High: 3+ sides available

Low - lEazar hall Materials can’t be stored on roof and no reasonable crane access points

High - mckimmon center 3 crane access points

Roof Install date& Type Date of most recent roof install Type of roof currently installed

Epdm EPDM rubber stands for Ethylene Propylene Diene Monomer (M-class)

Coal Tar Pitch

Roof Area Measured in ft^2

conclusion This project was almost completely student led There are several existing systems on NCSU’s campus Rooftops evaluated based on 10 criteria
