None of these solutions are anywhere near as easy as simply installing an A/C unit. Which is why A/C is so popular. People would love to cool (and heat) their homes in more environmentally friendly ways, provided those ways are as convenient and as cheap as A/C. Which they're not. If anything, insulation (on its own) worsens the problem, because once the heat gets in, it's effectively trapped for days. If it's not combined with shading, or some other way to reflect heat away from the windows, a hot house becomes a hothouse real fast... I wish there were an easy way to couple all heat producing and heat dissipating devices in my home. Too much heat in my bedroom? Move it into the hot water tank. Too cold in the living room? Use the waste heat from the oven to heat the room.
