The updates are really only a big deal if you live in climate zones 4 or 5, like 65% (or so) of America does. But don't worry, climate change is making it smarter than ever to exceed the code minimum.

There are new words and numbers in the energy code, like "tested for tightness," R-60, and 20+5

Energy recovery ventilators (ERV) replace kitchen and bath exhaust air with clean and tempered supply air

Everything there is to know (well, almost) about blower door testing with a few engineer-y jokes along the way.

Ceiling-mounted units practically disappear while delivering energy-efficient heating and cooling

Extreme heat and humidity can drive moisture deep into framing cavities which can cause mold, rot, and structural damage

Like kitchen bath remodels, it involves plumbing, ventilation, electrical upgrades, waterproofing, and building inspectors

These mighty-mites can provide heating, cooling, and air-mixing for a well-insulated house, but they look so darned—European. It is hard for many Americans to warm up to them.

The Model Remodel Show followed the progress of the 2017 Model Remodel project by Professional Remodeler magazine.

Match the pipe to the pressure

Dew point differs from relative humidity in that it measures exactly how much vapor is present. With relative humidity, it's all relative.

This chart explains how moisture behaves in the air as temperatures rise and fall—rainstorms, flooding, and glaciers in wall cavities are distinct possibilities.

Roof framing, window options, and a mechanical advantage add up to lower bills and a higher quality home
