Our Goal
Moderation of indoor temperature, providing conservation of energy and consistent comfort.

Cannington Active/Passive Solar Home
Initial readings - Solar heat only
April 5 - 23, 2010

Winter
Capture the Sun’s Heat
Using the black metal roof of the house as the active collector and 78% of the windows on the south for passive collection.
Store the Heat
Using a high efficiency low wattage blower we move the heat to the 1,920 cu. ft. of concrete and gravel thermal storage under the house.
Retain the Heat
Using super insulation methods:
- R20 Under storage
- R40 Surrounding storage
- R52 Walls
- R74 Attic
Summer
Capture the Cool
Cool nights, warm days, the system turns on at night to move cold air to storage.
Retain the Cool
Super insulation and the moderating effect of the thermal mass keep the temperature constant through most summer days and nights.
Added Conventional Energy
Adding electrical heat/cool during long periods of heat or cold is done at off peak periods (50% less than peak) and will retain that temperature for long periods.
Shade
Roof overhangs block out the high summer sun and allow the winter sun to penetrate well into the home heating the thermal mass from the top.
