Every year, BuildingGreen names the ten best green building products that, as the publication states, “transform the design and construction industry” by helping to solve environmental problems, from reducing greenhouse gas emissions to finding durable and safe materials.
Honeywell’s Solstice Liquid Blowing Agent — Based on hydrofluoroolefin technology, it replaces a high global warming potential blowing agent, HFC-245fa, found in spray polyurethane foam. Solstice has a 100-year GWP of 1, which means it is equal to carbon dioxide in terms of global warming potential. The product is used by Whirlpool in appliance lines, as well as for Lapolla’s Foam-Lok 2000 4G SPF wall insulation, and Henry-West Development Group’s 3012-EB-3 SPF roof insulation.
Whirlpool HybridCare Ventless Clothes Dryer — The ventless heat-pump dryer improves efficiency by using a refrigeration loop that condenses moisture from the drum and returns excess heat energy. HybridCare saves on HVAC energy, providing 40% energy savings over a standard dryer.
Sloan Hybrid Urinal — The urinal uses a water-free cartridge and automatic rinser to keep it clean and odor-free. The unit’s Velocity cartridge pumps liquid through it and out the drainpipe, lessening buildup, while a water solution called Jetrinse is flushed every 72 hours to keep solids from forming in the housing and drain line.
Gunlocke Savor Guest Chair with Ecovative MycoBoard Backing — This guest chair is made from an engineered-wood alternative made from mushroom mycelium, a root, and is as strong and stable as a standard plywood- or particleboard-backed chair.
Duo-Gard Bike Racks and Shelters — The racks can be incorporated into a building to help it achieve LEED status. The shelters’ roofs are made of standing-seam metal or polycarbonate, and walls are made of polycarbonate, safety glass, perforated metal, or steel or aluminum mesh. Photovoltaic panels and LED lighting can also be included.
NuLED Power over Ethernet (PoE) Low-Voltage LED Lighting — The system uses DC power from a standard PoE network, and it can monitor and control LED power consumption and color temperature, all with less energy loss than AC systems.
Personal Comfort Systems Hyperchair — When HVAC systems can’t accommodate everyone’s preferred indoor temperature, this office chair provides personal heating and cooling powered by a lithium ion phosphate battery and controlled by a panel on chair’s arm.
Unity Homes High-Performance Panelized Homes — The high-performance panelized home system uses computer numeric control equipment to help create panelized wall systems and small prefab room modules to minimize thermal bridging. Unity Homes use energy-saving insulation and FSC-certified wood with low-VOC finishes.
Sanden Heat Pump Water Heater with CO2 Refrigerant — This heat-pump water heater uses CO2 as a refrigerant and creates water temperatures high enough for hydronic heating. It can deliver around 16,000 Btu/hr and can produce 149°F water.
Tesla Powerwall and Powerpack Onsite Energy Storage — The rechargeable lithium-ion battery system incorporates liquid thermal management, battery management, and a DC–DC converter. It has a 10 kWh unit optimized for weekly or backup use and a 7 kWh unit for daily use.
