A few years back, CBS Early News did a segment with Bill Nye the Science Guy about how white rooftops could combat global warming — the idea being that darker rooftops retain heat and cause people to use more of their air conditioning.

A Modern-Shed customer recently brought this to our attention, and it got us thinking about all the ways a Modern-Shed could be made to be energy-efficient.

Our general manager, Tim, shares his own experience about how he heats and cools his own Modern-Shed:

I have a direct south and west exposure which brings in tons of natural light. Along with the upper clearstory transom glass, I also have a 6-foot sliding glass door and an awning window.

The Ply Gem window and door have excellent energy values and my shed has walls with R-21 insulation, a roof with rigid foam R-38 and a floor system with R-21. I use a small radiant heater in the winter to keep my office toasty warm. Set on the first of three levels at 68 or 69 degrees is all it needs due to the excellent insulation.

In the summer, I have a stand-alone AC unit that vents through the awning window very easily and I have curtains to block out the late afternoon sun, but then I can’t see out. I remembered from years ago when I sold sunrooms that glass is better shaded from the exterior before the sun/heat gets to the glass. So, I put an exterior roll up shade on the large window.

If you can stop or filter the sun’s heat before it gets to the insulated glass, the LowE/Argon glass doesn’t have to work so hard and is much more efficient. I ordered a roll down shade screen from Amazon, and with it, I really don’t even need the air conditioning, which I prefer, and can then use the lower awning portion the window to cool in the morning and evening hours.
