Choosing to build a net zero energy home can have a huge effect on not just reducing your environmental footprint, but on the cost of your home over its entire lifespan. You may have to invest more money into building a net zero energy home, but that the savings you’ll experience over the home’s life will be well worth it.
Once you factor in utility incentives or tax credits, your net zero energy home will only cost between 5 and 10 percent more to build than a normal home. The leftover difference will be recouped over the next 5 to 10 years in energy savings.
One of the key aspects to designing a net zero energy house is to build the most efficient building envelop that you can afford. The building envelope is the thermal barrier between the inside of your home and the outside of your home. The more effective it is, the less heat will leak out during the winter and the less cool air will escape during the summer.
