Description

Research proposal for the evaluation of the generation capacity of solar systems on commercial rooftops. Use of GIS to map roofspace and develop a model for calculation of output per square meter and best practices for a commercial install.

Reduce the wasteful use of water by the power industry Shift the economics of power generation to sustainable local systems Lower the use of fossil fuels and generation of CO 2 Reduce future demand for more power plants Address Social and QOL issues Overarching Goals

Reduce the wasteful use of water by the power industry

Shift the economics of power generation to sustainable local systems

Lower the use of fossil fuels and generation of CO 2

Reduce future demand for more power plants

Address Social and QOL issues

Project Goal Develop an inventory of commercial roof tops applicable for solar systems Develop an estimate of generation potential using these roof tops Investigate applicable technologies Economic and generation Proof-of-concept (will it work) Determine (if possible ) if commercial roof top solar systems will actually achieve the Overarching Goals Lower water use or growth of use at generation facilities Reduce reliance on fossil fuels Etc.

Develop an inventory of commercial roof tops applicable for solar systems

Investigate applicable technologies

Economic and generation Proof-of-concept (will it work)

Determine (if possible ) if commercial roof top solar systems will actually achieve the Overarching Goals

Lower water use or growth of use at generation facilities

Reduce reliance on fossil fuels

Etc.

The Plan Inventory of applicable commercial roof space Map showing prime properties GIS & database if possible ‘ Best-Practices’ and/or ‘State of the Industry’ Installation Technology (current and future) Estimation of Generation Potential How many Kwh generated based on acceptance

Benefits to Austin Energy Less load demand during peak times Offset future demand for more generation/plants Lower need to purchase fossil fuels Lower water use (my primary goal) Value to End-user Cost savings ‘ Good-will’ TBD The Payoff (What we hope to show)

Benefits to Austin Energy

Less load demand during peak times

Offset future demand for more generation/plants

Lower need to purchase fossil fuels

Lower water use (my primary goal)

Value to End-user

Cost savings

‘ Good-will’

TBD

Value to Austin Lower power generation cost leading to lower consumer cost Lower local water budget (less pumping from aquifer and river) Austin can become a solar hub Solar industries locate to Austin Prestige Local investment Cleaner local environment QOL increases Jobs Local economy Lower air pollution Austin is currently at non-attainment

Value to Austin

Lower power generation cost leading to lower consumer cost

Lower local water budget (less pumping from aquifer and river)

Austin can become a solar hub

Solar industries locate to Austin

Prestige

Local investment

Cleaner local environment

QOL increases

Jobs

Local economy

Lower air pollution

Austin is currently at non-attainment

Resources and Requirements Quite a bit of phone and face time with sources Screen time determining assets Some quantitative analysis Quite a bit of qualitative analysis GIS and database – if possible Some field trips to see installations, meet vendors and/or clients
