Zero Energy Walls

Stop building Victorian houses, use two by twelve inch walls in the 21 st century.

Introduction

Anyone building new construction, please consider making all exterior walls a minimum of two by twelve (2" x 12"). With a 2 x 12 wall you can achieve at least R40, this will reduce most heating and cooling energy needs for the house. You can even add inches to your walls for a retrofit to achieve this if you ever need to replace siding. Let's declare the end of the 2 x 4 for external walls. A rough estimate is that it will cost between 5% and 7% extra. I've recently finished a building and some things that change are: window sills and door openings become deeper. So instead of expensive and time consuming molding, I just turned the sheetrock into the opening and the window sits toward the outside of the building. This also allows one to just do simple tidy-up molding around the window. The sill is larger and becomes a nice feature for books or plants. See the video for more detail.

Understanding the Market

This is where you can describe what already exists, what is needed, etc. You may want to include inline references. [1]

To make bullets use the asterisk:

• Like this

You may need deeper level headings. Just keep adding equal signs to get that.

Costs

You may describe your costs here.

row 1, cell 1 row 1, cell 2 row 1, cell 3
row 2, cell 1 row 2, cell 2 row 2, cell 3
