  1. 1. Passive Solar: Using Heat From The Sun Solar Sun Flames 2 Passive Solar by P. Anna Paddon 09-16-2012Passive SolarSunshine In Our Everyday Lives Powerpoint Templateshttp://www.originenergy.com.au/2027/Passive-solar Page 1
  2. 2. First Page : Passive Solar Sunshine In Our Everyday Lives We use sunshine everyday. Here are some common ways that sunlight is used for light and heat: • windows to let in light and warmth to rooms • drying clothes in the sun • sun dried food such as tomatoes, sultanas and apricots. Homes can be designed to make the best use of the sun for warmth in winter while keeping the heat out in summer. This is called passive solar heating.

  3. 3. Second Page : Passive Solar Sunshine In Our Everyday Lives ● Typical features of passive solar design are: • Eaves (where the roof overhangs to provide shade) to keep summer sun out but let winter sun in • North facing windows to maximize solar gain in the winter • Insulation (especially in roofing) to reduce heat loss in winter and heat gain in summer. Extra information: The Australian Greenhouse Office has an interesting fact sheet about passive solar house design. Powerpoint Templateshttp://www.originenergy.com.au/2027/Passive-solar Page 3

  5. 5. Fourth Page : Passive Solar Sunshine In Our Everyday Lives PASSIVE SOLAR INVESTIGATIONS: ● ··Investigation 1: Warm in the sun ··Investigation 2: How much sunshine is in your neighbourhood? Learn about: Thermal solar, Photovoltaic cells Solar Sun Flames 1 Thermal Solar P. Anna Paddon 09-16-2012 ppt. Powerpoint Templateshttp://www.originenergy.com.au/2027/Passive-solar Page 5
  6. 6. Fifth Page : Passive Solar Sunshine In Our Everyday Lives Investigation • ··Investigation 1: Warm in the sun In Class Task : Record the temperature difference between sunny and shady areas, inside and outside. 1. W hat you need- Thermometer• Piece of dark cardboard (just a bit bigger than your thermometer)• Pad and pencil to record temperature• Watch or clock – and 25 minutes Discuss findings. Step 1- Record the outside temperature in the shade. Choose a shady outdoor area. Give the thermometer enough time to adjust and then record the temperature on the record sheet. Step 2- Record the outside temperature in direct sunlight. Choose a sunny area outside. 2. Give the thermometer time to adjust and record the temperature on your record sheet. Make a note ofany clouds. Create Step 3 - Record the inside temperature in direct sunlight. Choose a sunny area inside close to a north facing window. Give the thermometer time to adjust and record the temperature on your record sheet. a list of everybody’s Step 4- Record the inside temperature away from direct sunlight. Choose a sunny area results. inside close to a north facing window. Give the thermometer time to adjust and record the temperature on your record sheet. Discuss Step 5 • Make observations of variables that might change the temperature, i.e., clouds, rain, wind. • Present your results in a table (use the example below). why the findings are the Warmest spot same or different. Coolest spot Difference in temperature Powerpoint TemplatesPassive Solar Investigations: Solar Energy www.originenergy.com.au/education Page 6http://www.originenergy.com.au/2027/Passive-solar
  7. 7. Sixth Page : Passive Solar ··Investigation 2: Sunshine In Our Everyday LivesHow much sunshine is in your neighbourhood? Investigation Investigation 2 How much sunshine is in your In Class neighbourhood? Task: Find out how the hours of sunshine change over a year. The amount of daylight (and sunshine) is different every day. Winter days are shorter and Discuss findings. summer days are longer. This is important for solar power. Please answer the following questions 1. When is the longest day of the year in the southern hemisphere? Create 2. About how many hours of daylight does the longest day (approximately) have where you live? 3. When is the shortest day of the year in the southern hemisphere? 4. About how many hours of daylight (approximately) is this? a list of everybody’s The longest and shortest days are called the summer and winter solstice. It’s also results. the day when the sun is highest or lowest in the sky. Please answer the following questions Discuss 1. In winter, is the sun higher or lower in the sky? 2. What difference does this make to ‘passive solar’ heating? 3. Does daylight saving make any difference to the length of daylight? [Extra link]: Sunshine MAPS why the findings are the The Bureau of Meteorology records the number of hours of sunshine all across Australia. They use same or different. these measurements to make climate maps that show the hours of sunshine. http://www.bom.gov.au/cgi-bin/climate/cgi_bin_scripts/sunshine-hrs.cgi Use the maps to find the sunshine hours per day for where you live, and then answer the following.
