This document discusses passive solar design and how it uses sunlight for heating homes. Passive solar design features include eaves to block summer sun but allow winter sun, north-facing windows to maximize winter sunlight, and insulation to reduce heat loss. Homes can be designed to take advantage of sunlight for warmth in winter while keeping heat out in summer through passive solar techniques. The document also describes classroom investigations for students to measure temperature differences between sunny and shady areas and to track sunlight hours over the course of a year.

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.

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.

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.

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).

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.
