  1. Passive Solar Heating David Konopka

  2. What is passive solar heating? • Strategic home design for heat regulation • Not mechanical or electric • Placement • Insulation/materials • Channeling solar energy with mirrors and lenses • Widely applicable • Reduces pollution and energy costs • Energy produced near consumer • Useful in developing nations

  3. History • Essential before electric heating • Ancient Greece and China • Ancient Greek ‘sauna’ Modern • Solar cooker • Solar furnace • Greenhouse

  4. Home Design • Insulation- thermal mass • Windows and glaze • Sunroom/Solarium • Vents/convection/Solar Chimney • Heat-reflective ‘Cool Roof’ • Shade (ex. trees) • Home orientation • Location-based • Only effective if professionally done

  5. Solar Cooker • Focuses sunlight into a small area OR • Absorbs sunlight to heat up • Cooks food • Boils (sterilizes) water • Improved health • Reduces pollution and deforestation • Free operation when sunny

  6. Solar Forge • Reflects/concentrates heat • Good for small processes in sunny areas • First ‘modern’ solar forge in France 1949 (sunny 300 days a year) • May require input of energy to align mirrors

  7. Advantages and Disadvantages Pros • Saves money (usually free once implemented) • No fuel input • Reduces deforestation and CO2emissions • Compliments other heat sources • Improves health • Good for heating and cooling • Useful in developing nations Cons • Reliant on weather • No electric output • Often slower than conventional methods (solar forge) • Usually not sufficient to heat a home • Inefficient unless professionally done • Not useful for transportation
