Green building is improving the way that homes and homebuilding sites use energy, water, and materials to reduce the impact on human health and the environment. Building a green home means making environmentally conscious and sustainable decisions throughout the building process. These decisions aim to minimize the environmental impact of the home while it is being built and over the many years it will be lived in.
Green homes incorporate resource efficiency into every step of the building process to minimize environmental impact. The design, construction, and operation of a home must focus on energy and water efficiency, resource efficient building design, eco-conscious materials, indoor environmental quality, and must take the home's overall impact on the environment into account.
