Solar Gain

December 5th, 2006

Today’s high temperature was 37, with strong winds too. That may sound mild to readers in the mid-west, but it’s brrr cold for us. The wind rattled the vents in the kitchen and bathroom and I could feel a draft around them (I should stuff something in them until the ventilation fans are connected). And the heat won’t be installed until later this week.

Luckily, the sun came out mid-morning and the house warmed up quickly. The temperature inside got up to about 58 degrees, which was fine for working. That 20-degee heat gain is also a good sign for the (basic) passive solar features I designed into the house.

My east-facing patio doors pick up lots of morning sun, and my 4 big south-facing windows gain heat all day. My plan is to put tubes filled with water (like these) inside the south windows to gather the sun’s heat all day, then slowly release it into the house at night. The windows will get insulated covers to prevent the heat from just leaking back outside.
