The Construction of a High Performance Home: Week 8

The Construction of a High Performance Home: Week 8 1

I stopped by the high performance home site today and listened to the subcontractors in the attic above me murmuring about how it was such a pain to get anything done with the membrane already installed on the ceiling below. I chuckled. As high performance home builders, paying attention to energy details is important to us, and…

The Construction of a High Performance Home: Week 7

Hey now! Despite the blizzard of the century, perhaps even the history of the universe, great progress was made on the project last week. The windows were delivered to the site the day after the storm, before we even had a chance to dig out and were all in their final resting place by noon…

The Construction of a High Performance Home: Week 6 4

With the roof framing completed and the waterproof membrane in place, the focus has turned to finishing the interior framing so the electricians and plumbers can move in and begin their work. Once that’s completed, the crew will move back outside and complete a few minor framing items, like the two car garage.   Now…

The Construction of a High Performance Home: Week 4 10

The Construction of a High Performance Home: Week 3 14

Weather is a fickle thing. One minute it’s snowing, and the next minute it’s snowing again. Then, just like that, it starts snowing again. This week, we received over eighteen inches of snow, which buried our hopes and production expectations for the week. Nevertheless, when I left the site Friday afternoon, the concrete was being…

The Construction of a High Performance Home: Week 2 16

Winter has returned with a vengeance, which only adds to my already growing disdain for it. February is the worst. Next month, March will be the worst. Construction during the winter can be like running an uphill marathon. Twice. Everything takes longer than it should, and the coffee gets cold way too quickly. Cold coffee…
