Global Innovation Award Winners Are Green Trendsetters
Sustainability and green building remain in high demand in the residential construction industry. Eco-conscious home buyers looking to reduce their carbon footprints continue to seek out builders and product manufacturers who provide environmentally sound housing options and energy efficient goods.
NAHB’s annual Global Innovation Awards (GIA) honors the companies and builders leading the way in producing cutting-edge products, services, homes and communities that impact the industry on an international scale, including those that focus on green building and related products.
In 2023, the companies that took home the GIA Silver Award at the International Builders’ Show in Las Vegas covered a variety of environmentally friendly categories — from sustainable housing to air purification — and are recognized as forward-thinking champions of the industry:
Green Homes Australia’s Perth Show Home
Green Homes Australia’s unique and sustainable design scored them GIA’s Home of the Year Award. The green builder’s show home in Perth, Western Australia, has two levels and is fully electric. It has a 6 kilowatt (kW) solar panel system and a 4kW battery that stores excess solar power for later use. The home comes with a passive solar heating and cooling system, using sunlight to heat the space at night and during the winter months. In the spring and summer, the home stores cool night air to use throughout the day.
LG Inverter Heat Pump Water Heater
LG’s Inverter Heat Pump Water Heater is ENERGY STAR-certified and offers an eco-friendly alternative to traditional electric or gas water heaters. It uses inverter technology to heat water, which LG states can provide home owners with a cost savings of about 70% compared to a conventional electric heater.
Panasonic WhisperAir Repair Spot Air Purifier
Panasonic’s WhisperAir Repair Spot Air Purifier is a compact ceiling-mounted device that is part of its Healthy Home Solutions product line. It is designed to improve air ventilation using patented nanoeX technology, which purifies contaminated air using reactive molecules. This technology can help inhibit the spread of airborne pollutants such as mold and viruses, according to the manufacturer. This air purifier is also certified by the California Air Resources Board, because it complies with ozone emission limits.
