Description

Teaches the skills and knowledge necessary for the design and analysis of renewable energy designs on a variety of scales; from individual appliances through single family homes to regional power plants.  On the ground measurements are coupled with computer spreadsheets and established values for analysis. Hydroelectric, wind, biomass, geothermal, biomass and solar (both thermal and electric) sources are studied.  Background content in thermodynamics and the design process inform design projects that minimize environmental impacts.  Projects this year include improvements to the existing barn PV system and other campus improvements. 


Renewable Energy System Analysis and Design Syllabus

Spring 2013

 

Instructor: Adrian Owens

Pre-requisites: NS205:Environmental Science

                       

Texts: The Renewable Energy Handbook: 2009, William H. Kemp

Supplemental Readings:

            The Solar Electric Independent Home Book, 1995, Fowler Solar Electric

            Designing Your own House Your Own Way, Sam Clark

            Energy Isn’t Easy


Goals: 

To teach skills and knowledge necessary for analysis and design of renewable energy systems on a variety of scales.  Focused on heat and electrical production more than transportation.

  • Thoroughly understanding electrical quantities and basic wiring.
  • Quantifying parameters for existing solar, hydro-electric, wind, biomass, and geothermal technology will be taught as well as relevant thermodynamic principles.
  • Exploring newer technology and storage systems
  • Following an iterative design process:
                Stating design parameters
                Drafting clear diagrams
                Calculations clearly shown
                Review by peer, instructor, client.
                Prototype testing
                Revised written proposal
  • Minimizing environmental impact

 

Format:

Design projects will be informed by direct instruction, readings, “library” research, field trips to local facilities, and hands-on installation.  Calculations using hand calculators and computer spreadsheets are a central pillar of the course.  This year group projects are refurbishing the PV/Wind Electric system at the Sterling Barn, lighting and thermal design of the Sterling Dining Hall, and a greenhouse heating system.

Individual design Projects will also be chosen by each student.
