Project GOTChA chart

This quad chart gives a snapshot of the planned activities for the term, at a high level. This information is presented here in the form of a GOTChA chart.

Goals

  • Build an integrated team (SCI-Arc + Caltech) that can win the 2011 Solar Decathlon
  • Complete the design development phase of the Solar Decathlon competition and submit design documents on time
  • Evaluate and explore options for providing some technology sizzle in our design

Technical Challenges

  • Bring 20-30 new Caltech students from diverse backgrounds and skill levels up to speed quickly
  • Integration of SCI-Arc and Caltech activities (people, goals, schedule, deliverables)
  • Some existing baseline designs are not very complete; need more work and re-validation
  • Some subsystems have no baseline design

Objectives

  • Assign students to subsystems and teams, with linkages between teams with overlapping functionality or interfaces
  • For subsystems with existing baseline designs:
    • Revalidate the baseline design computations and verify that baseline can achieve maximum points for relevant competition(s)
    • Communicate and agree on specifications and choices with IPT and SCI-Arc teams
    • Perform model-based analysis of system performance in a form that can be used for trade-off studies
    • Document the baseline design in a manner that is compatible with design development phase deliverable
    • Evaluate technology options that can be incorporated into our design and perform cost analysis for each
  • For subsystems without existing baseline designs:
    • Analyze options design with performance, cost, electrical load, thermal load estimates
    • Establish a baseline design that can achieve maximum points for relevant competition(s), in agreement with IPT and SCI-Arc teams
    • Document the baseline design in a manner that is compatible with design development phase deliverable
  • Develop and maintain system-level cost and energy budgets and use these to verify ability to maximize points on engineering-driven competitions
    • Provide a design capable of full capability (max points) with net-zero energy consumption for 95th percentile day
    • Provide a design capable of 90% max points on worst case day (over last 20 years)

Approach

  • Stick to summer 2010 system architecture decisions; avoid re-inventing the wheel
  • Hold off on alterations to the baseline until we have a fully analyzed, documented and costed baseline
  • Schedule planning event with Caltech + SCI-Arc to help people meet each other and align goals, milestones and schedule
  • Make use of the project wiki as a mechanism to document and enhance team communication
  • Identify individual students who will be responsible for insuring good cross-project integration between appropriate groups
  • Develop analytical or computational models demonstrating that specifications can be met
  • Milestones
    • 13 Oct: each subsystem team knows what SD rules apply to their subsystem + understand existing baseline design
    • 27 Oct: revalidated/preliminary baseline design computations for each subsystem (depending on initial state); shared decision making between SCI-Arc and Caltech
    • 10 Nov: rigorously analyzed and documented baseline designs complete for all subsystems
    • 23 Nov: design development documentation complete and delivered to DOE
    • 10 Dec: final reports for each student due, with complete subsystem documentation available on project wiki
