An Eco-friendly home or a green home is a house that is built and designed using environmentally friendly techniques, materials, and appliances. An Eco-friendly home doesn’t just mean a home where your roof is covered in solar panels — it can be anything from energy-efficient lighting to low-flow water fixtures, using soy paint from installing large windows to optimize natural light. A smart and true Eco-friendly home is a home containing features that are environmentally cautious within its design, construction, operation, and maintenance.
