#1 What are Net-Zero Energy Homes?
Answer: Net-Zero energy homes are houses that have been specifically designed and built to produce just as much energy as they consume, if not more. Through a combination of energy saving appliances, tight insulation and renewable energy sources like solar panels and geothermal systems, a Net-Zero home effectively eliminates your energy costs and environmental impact on the world, hence the name. Choosing a Net-Zero energy home is perfect for both environmentally and cost-conscious homeowners.
Builder Tip: Before you start making plans to build a Net-Zero energy home, take an inventory of exactly how much energy you use in a typical month. This will give you a better idea as to how efficient your home needs to be and how it should be designed.
