A green home is a type of house designed to be environmentally sustainable. Green homes focus on the efficient use of "energy, water, and building materials". [1] A green home may use sustainably sourced, environmentally friendly, and/or recycled building materials. This includes materials like reclaimed wood, recycled metal, and low VOC (volatile organic compound) paints. Additionally, green homes often prioritize energy efficiency by incorporating features, such as high-performance insulation, energy-efficient appliances, and smart home technologies that monitor and optimize energy usage. Water conservation is another important aspect, with green homes often featuring water-saving fixtures, rainwater harvesting systems, and grey water recycling systems to reduce water waste. It may include sustainable energy sources such as solar or geothermal, and be sited to take maximum advantage of natural features such as sunlight and tree cover to improve energy efficiency.

Elements

No government standards define what constitutes a green remodel, beyond non-profit certification. In general, a green home is a house that is built or remodeled in order to conserve "energy or water; improve indoor air quality; use sustainable, recycled or used materials; and produce less waste in the process." This may include buying more energy-efficient appliances or employing building materials that are more efficient in managing temperature. [2]

A green home often incorporates design elements that maximize natural lighting and ventilation, reducing the need for artificial lighting and HVAC systems. Additionally, sustainable landscaping practices, such as native plantings and rainwater harvesting systems, can further enhance the eco-friendliness of the property. Integration of renewable energy sources like solar panels can also contribute to the overall sustainability of the home, reducing reliance on non-renewable energy sources and decreasing greenhouse gas emissions. In essence, a green home strives to minimize its environmental impact throughout its lifecycle, from construction to daily operation and eventual disposal or repurposing of materials.

History

United States

In the United States, the green building movement began in the 1970s, after the price of oil began to increase sharply. In response, researchers began to look into more energy efficient systems. Nevertheless, individuals required persistence to navigate the bewildering array of incomplete and imperfect information that was the wilderness frontier of what is now known as green building. In 1999, Richard and Katherine Homan began building Dallas, Texas' first comprehensive green home. [3] It took until 2012 for the city to issue a proclamation for having the city’s first comprehensive green home.

Many organizations were founded in the 1990s to promote green buildings. Some organizations worked to improve consumer knowledge so that they could have more green homes. The International Code Council and the National Association of Home Builders began working in 2006 to create a "voluntary green home building standard". [4]

The Energy Policy Act was enacted in 2005, which allowed tax reductions for homeowners who could show the use of energy efficient changes to their homes, such as solar panels and other solar-powered devices. [5]

Certifications

Various types of certifications certify a home as a green home.

United States

LEED: The U.S. Green Building Council has a green certification titled Leadership in Energy and Environmental Design. [6] The factors that it considers include "the site location, use of energy and water, incorporation of healthier building and insulation materials, recycling, use of renewable energy, and protection of natural resources". [7] LEED offers a specific certification track for residential buildings, known as LEED for Homes. This program assesses the environmental performance of single-family homes, multifamily buildings, and mixed-use developments, considering factors such as location, water efficiency, materials selection, and indoor air quality. [8]

Model Green Home Building Guidelines: The US National Association of Home Builders independently created its Model Green Home Building Guidelines as a type of certification, along with programs for utilities. [9] [10]

ENERGY STAR: In the United States, the ENERGY STAR program, administered by the Environmental Protection Agency (EPA), certifies homes that meet stringent energy efficiency standards. ENERGY STAR-certified homes are designed to use less energy for heating, cooling, and water heating, resulting in lower utility bills and reduced greenhouse gas emissions. [11]

Passive House: The Passive House Institute and Passive House Institute US (PHIUS+) standards focus on designing and constructing ultra-low energy buildings that require very little energy for heating or cooling. Passive House certification requires rigorous adherence to specific energy performance criteria, including airtightness, high-quality insulation, and mechanical ventilation with heat recovery. [12]

International

Living Building Challenge: This certification program, administered by the International Living Future Institute, goes beyond traditional green building standards by emphasizing regenerative design principles. Buildings certified under the Living Building Challenge must meet strict criteria related to energy, water, materials, equity, and beauty, and must demonstrate net-positive impacts on the environment and community.[ citation needed ]

BREEAM (Building Research Establishment Environmental Assessment Method): Originating in the United Kingdom, BREEAM is a widely recognized green building certification system used internationally. It assesses the environmental performance of buildings based on criteria such as energy and water use, materials selection, waste management, and ecological impact.[ citation needed ]

Australia

Green Star: Green Star is an Australian sustainability rating system for buildings and communities, developed by the Green Building Council of Australia. It evaluates the environmental attributes of buildings across categories such as energy efficiency, indoor environmental quality, transport, and innovation.[ citation needed ]

India

IGBC-Certified Green Home The Indian Green Building Council (IGBC), part of the Confederation of Indian Industry was formed in the year 2001. The council offers a wide array of services that include developing new green building rating programmes, certification services and green building training programs.[ citation needed ]

Global examples

Earthship Biotecture (Taos, New Mexico, USA): Earthships are a unique type of sustainable home pioneered by architect Michael Reynolds. These homes are built using recycled materials such as tires, bottles, and cans, and they utilize passive solar heating, natural ventilation, and rainwater harvesting systems to achieve off-grid living. The thick walls made of rammed earth or tires provide excellent thermal mass, helping to regulate indoor temperatures year-round. Earthships often incorporate greenhouse spaces for food production, further enhancing their self-sufficiency and sustainability.

The Zero Carbon House (Birmingham, UK): The Zero Carbon House, also known as the 'Balsall Heath House,' is an innovative example of sustainable retrofitting. Originally a Victorian terraced house, it was transformed into a zero-carbon dwelling through extensive renovation and the integration of energy-efficient technologies. The house features high levels of insulation, triple-glazed windows, airtight construction, and rooftop solar panels for renewable energy generation. It also incorporates passive design principles to minimize energy demand while maximizing comfort for occupants. The Zero Carbon House serves as a model for reducing carbon emissions in existing urban housing stock.

"Sustainability," was defined as “development which implies meeting the needs of the present without compromising the ability of future generations to meet their own needs”as defined by the 1983 Brundtland Commission. As sustainability gains support and momentum worldwide, universities across the United States have expanded initiatives towards more sustainable campuses, commitments, academic offerings, and student engagement.

Zero-carbon housing is a term used to describe a house that does not emit greenhouse gasses, specifically carbon dioxide (CO2), into the atmosphere. Homes release greenhouse gases through burning fossil fuels in order to provide heat, or even while cooking on a gas stove. A zero carbon house can be achieved by either building or renovating a home to be very energy efficient and for its energy consumption to be from non-emitting sources, for example electricity.

Sustainable refurbishment describes working on existing buildings to improve their environmental performance using sustainable methods and materials. A refurbishment or retrofit is defined as: "any work to a building over and above maintenance to change its capacity, function or performance' in other words, any intervention to adjust, reuse, or upgrade a building to suit new conditions or requirements". Refurbishment can be done to a part of a building, an entire building, or a campus. Sustainable refurbishment takes this a step further to modify the existing building to perform better in terms of its environmental impact and its occupants' environment.

A green design concept is to facilitate sustainable use of the resources – energy, water and other materials – all through the complete life cycle of the building including its construction.
