The stanford delivery process where are we
The Stanford Delivery Process:Where Are We?

  • Feasibility Phase Completed

  • Waiting for Board of Trustees Approval to begin Schematic Design

  • Design options have been proposed, but no decisions have been determined





Goal model evolution
Goal Model Evolution

2. Insert additional goals to form comprehensive list for energy technologies

1. Extract goals from existing list that relate to energy technologies

  • - Comparable Student Cost

- Innovative Leadership on Campus

- Realistic New Technologies

- Electricity Quality and Reliability

3. Organize goals to create balanced model

  • Remove some goals

  • Add/Combine some goals:

- Ease of Operation and Maintenance

- Incorporates Ongoing Research

- Model for Sustainable Living

Biogas digestor
Biogas Digestor

  • Reactor tank

  • Produces methane gas from anaerobic digestion

  • Odor issues?

  • Ongoing research by Gil Masters and Craig Criddle


Microturbine
Microturbine

  • Combined Heat and Power (CHP)

  • Save 40 - 50% of energy compared to conventional power plant

  • Ongoing research by Gil Masters and Craig Criddle


Fuel cell
Fuel Cell

  • Combined Heat and Power (CHP)

  • Save 40 - 50% of energy compared to conventional power plant

  • Ongoing research by Gil Masters and Craig Criddle


Stirling engine
Stirling Engine

  • Combined Heat and Power (CHP)

  • Capture and use waste heat from small power plants located at the end use

  • Save 40 - 50% of energy compared to conventional power plant

  • Ongoing research by Gil Masters and Craig Criddle


Photovoltaic cells
Photovoltaic Cells

  • Use sunlight to generate electricity

  • Renewable resource

  • Low operation and maintenance involved

  • Ongoing research by David Sheu


Electric vehicles
Electric Vehicles

  • Store extra electricity in plug-in hybrid vehicle, use as emergency generator

  • Electricity equivalent ≈ $1/gallon

  • By charging during off-peak hours, 70% of light-vehicle miles could run on today’s electricity grid

  • Ongoing research by Paul Kreiner


Energy efficiency smart grid smart building
Energy Efficiency: Smart Grid & Smart Building

  • Monitor electricity rates

  • Adjust building electricity usage dynamically

  • Minimize electricity costs


Geothermal heat pump
Geothermal Heat Pump

  • Pumps heat to or from the ground into building

  • Uses less electricity than typical furnace

  • Can also be reversed for air conditioning


Solar water heater
Solar Water Heater

  • Passive: Integral Collector Storage (ICS)

  • Potentially no pump, no controller, no sensors, but depends heavily on climate and time-of-use

  • Ongoing research by Jonas Ketterle


Greywater heat recovery
Greywater Heat Recovery

  • Ongoin research by Paul Kreiner

  • Take heat from used shower water and turn into energy


Radiant slab heating
Radiant Slab Heating

  • Run tubing inside floor to move heat through building

  • Heat rises up from floor to the air

  • Feet always warm

  • Currently used in some Stanford graduate student housing
