Net-Zero Defined
A net-zero home produces as much energy as it consumes over the course of a year. This requires two components:
- Extreme efficiency: Minimizing energy demand through insulation, air sealing, and efficient systems
- On-site generation: Solar panels (typically) that produce enough electricity to offset consumption
The "net" part is important: the home may draw power from the grid at night and export excess during the day. Over a year, these balance to zero (or better).
Net-Zero Ready Defined
A net-zero ready home has all the efficiency features of a net-zero home but doesn't include the solar panels. It's built to be so efficient that adding a modestly-sized solar system later would achieve net-zero status.
DOE Zero Energy Ready: Austin Touchstone Builders is a certified DOE Zero Energy Ready Home partner. This federal program verifies that homes meet rigorous efficiency standards through third-party testing.
Which Should You Choose?
Choose Net-Zero Ready if:
- You want to spread out costs over time
- Solar incentives might be better in a few years
- Your site has shading issues to address first
- You want the efficiency benefits now without solar commitment
Choose Net-Zero if:
- You want to maximize current federal tax credits (30%)
- You want energy independence from day one
- You're concerned about future utility rate increases
- Grid independence is important to you
The Cost Difference
The efficiency features are the same for both. The difference is the solar system, typically $20,000-$40,000 before tax credits. After the 30% federal credit, that drops to $14,000-$28,000.
Whether you install solar now or later, starting with a highly efficient home ensures you'll need a smaller, less expensive system.
