There are many reasons for owning or purchasing a green home…
The technologies and practices required to build a green home to certain criteria may result in lower costs to operate the home. Energy-efficient appliances, lighting systems, and HVAC equipment result in lower energy consumption compared to other models. Using less water through water-conserving faucets, showers, toilets, and irrigation systems may also result in less water consumption. Properly sized HVAC systems mean that less energy is needed to condition spaces. Employing technologies such as photovoltaic panels for solar electricity and water heating, and geothermal heat exchangers could reduce dependence on public utilities, too.
Effective storm water management and landscaping could mean less time maintaining outside spaces. Also, green building practices lead to the use of some longer-performing materials and careful construction assemblies. Drained foundations, water spouts on gutters, and flashing around windows and doors might reduce the opportunity for system failure within the home due to moisture intrusion.
INDOOR ENVIRONMENTAL QUALITY
Indoor air quality is one of the guiding principles of the ICC 700-2008 National Green Building Standard and the NAHB Model Green Home Building Guidelines. Homes that allow for proper air exchange through ventilation, and low-emitting products like low- or no-VOC paints reduce off-gassing. Further, green building practices look at reducing the opportunity for moisture intrusion. The efficient HVAC systems, windows, and floor plans also mean that heating and cooling is better distributed throughout the home.
Increased energy and water efficiency in construction could lead to decreased energy and water consumption in a home throughout its lifespan. Further, some renewable, recycled, and other efficient building products used in green home construction may reduce the impact on natural resources. Also, green homes often include resource and waste reduction and recycling amenities.
