This is Mike's low thermal mass sunspace in Colorado. Its a great example of the same sunspace serving many purposes -- its used for all of these things:
- Provides lots of heat to the house.
- Its a popular place for the family to gather, kids to play, or just to have a cup of coffee and look at the view.
- Is a great place to dry clothes, firewood, and food.
It also looks great, and adds value to the house.
I don't know of any solar project that pays off on so many fronts.
Thanks very much to Mike for providing the description, measuring the performance, and suffering my endless questions!
In addition to the pdf description of the design and build of the sunspace, Mike has provided a spreadsheet that shows how the heat that the sunspace provides to the house is measured and calculated, and also allows you to change the various parameters to see how it effects the heat produced.

A sampling of pictures:
While the space heating of the house is the sunspaces major contribution to energy saving, just consider that having a good, year round place to dry clothes saves an additional 1200 KWH of electricity and 2000 lbs of CO2 emissions a year -- about the same as a 1000 watt PV array would produce. Mike is working on a way to add solar preheating of domestic water to the sunspace -- potentially another several thousand KWH per year energy saving.
Its just amazing how versatile these sunspaces can be.
Mike has added a sunroom loft play area and a climbing
Sort of a treehouse in the sunspace.
No end to the things a sunspace can be used for!
