As noted, miserably cold in these parts. Over the weekend, we turn down the heat in the office since we're not there, don't want to waste. Not down to zero, but low. Monday, it took hours to come up to "room temperature." Tuesday, even though we'd left the heat on overnight, it was still cold. Partly it was just so cold outside, partly every time someone opens the outer door, cold air spills in (there is an entry area, but not perfect), and partly the heat in the common areas of the building (my office is in a 7-story condo building) was out, so we had cold walls on all 4 side of my office, and our heating couldn't keep up. By noon, with the day having warmed up a bit, and the sun coming down, it was a bit better. I left the curtains open in the exam rooms (unless someone was actually undressing) to get more sunlight (and therefore heat) into the rooms. Even at home, despite the house being well-insulated and having a good heating plant, the rooms still didn't come up to proper temperature (although much better than the office). I turned up the heating in the basement, which helped. The basement has separate baseboard heaters; we usually keep the temperature lower there than the main floor (again, why waste), but with its being that cold, turning up the heat in the basement warmed up the floor of the ground floor to normal temperature. Today I brought a space heater into the office so Evil Secretary (who faces the entry doors) could keep her feet toastie, but it is warmer today.
