Unpainted Wooden
How much more heat will an unpainted wooden house absorb than one painted white?
I have learned from this site (thanks U all) that black absorbs more heat than white colored objects and why. Now I would like to know of the 3, a white painted, black painted or plain wood house, where the plain wood house would fall in the heat absorption area
Plain wood will fall between white paint and black paint. It will actually be a lot closer to white paint in heat absorption. The difference between any of these is in the range of 100s of BTUH. In the total heat load of a house this is very small. AC is usually measured in tons and one ton of AC is 12,000 BTUH. A typical house uses 2 to 3 tons of AC so the difference of even several hundred BTUH out of 36,000 BTUH is only about 1 percent. If you are looking for real cooling advantages you need to look at things like window types, building insulation, and shading the building with trees. The savings from these items can be much more significant.
