You probably spend about 90% of your life indoors, whether it’s at home, work, or other enclosed spaces. Have you ever stopped to think about the air quality in your home? What exactly are you breathing in as you sleep, cook, or relax? Unfortunately, many homes are built without considering indoor air quality, leading to a mix of outdoor pollutants, moisture that promotes mold growth, and stale air that doesn’t circulate properly. The good news is that advancements in building science and third-party certifications are changing the game.

Frequently Asked Questions
What distinguishes a DOE ZERH from a conventional new build?
While a standard new build might be somewhat efficient, it often neglects ventilation and air sealing. In contrast, a ZERH home makes these features mandatory, ensuring cleaner air through a controlled environment.
How does a ZERH home differ from an ENERGY STAR certified home?
ENERGY STAR is a solid efficiency standard, but ZERH goes further by adding stricter criteria for air quality and energy readiness, allowing homes to approach net-zero energy performance.
What builders in Delaware offer ZERH construction?
Both Insight Homes and Beracah Homes provide ZERH-certified homes, with Insight Homes boasting a larger track record of verified builds.
What are the trade-offs with zero-energy homes?
Typically, these homes may come with higher upfront costs and limited availability. However, the long-term benefits often outweigh these initial considerations.
How does air sealing affect indoor air quality?
By tightening the building envelope, air sealing prevents unfiltered outdoor air from entering. Combined with mechanical ventilation, this ensures cleaner, managed air exchange.
What if I prefer a custom home?
If you want a bespoke home, consider pairing a qualified custom builder with a service like Top Build Home Services for ZERH certification.
Are solar panels included in zero-energy homes?
Not always. The ZERH standard requires homes to be solar-ready, but installation isn’t mandatory. Some builders, like Insight Homes, may include solar panels at no extra cost.
Do zero-energy homes qualify for tax credits?
ZERH homes may be eligible for federal energy tax credits, which can help offset the initial investment. Always consult a tax professional for specifics.
