Green Proving Ground Selects Innovative Technologies that Improve Building Health and Resilience

WASHINGTON — The U.S. General Services Administration’s (GSA) Green Proving Ground (GPG) program, in collaboration with the U.S. Department of Energy (DOE), has selected five innovative building technologies for evaluation in GSA facilities. The American-made technologies were chosen in response to GSA’s most recent Request for Information (RFI) seeking resource-efficient technologies that improve commercial building health and resilience.  The results are intended to help validate the technical and operational characteristics of the technologies and their potential for future deployment.

Automated Air Sealing, Aeroseal (Miamisburg, OH) – Air leakage is a significant driver of energy use within buildings, in some instances being the largest driver of heating and cooling loads. This technology seals the building envelope by pressurizing it and then distributing an atomized non-toxic water-based sealant that is automatically drawn to leaks. System software records progress in real-time, allowing users to control the desired level of envelope air-tightness.

Nanofiber Air Filters, eSpin (Chattanooga, TN) Increasing filter performance in heating, ventilation and air conditioning (HVAC) air-handling units is recommended by the Centers for Disease Control and Prevention as a way of improving workplace safety in response to airborne pathogens such as COVID-19. These high-capacity HVAC filters use nanofiber media to improve filtration effectiveness, while simultaneously improving energy efficiency by lowering airflow restriction.

HVAC Pretreatment Dehumidification, Academy Energy Group (Newburgh, IN) / Altaire (Ellisville, MO) – Precise humidity control in buildings reduces airborne pathogens and improves indoor air quality. This retrofit technology controls the building’s humidity level by treating outside air before it enters the HVAC system. Decoupling humidity control from heating and cooling enables improved indoor air quality management, while reducing energy consumption.

Coreless Axial Flux Motor, Infinitum Electric (Round Rock, TX) – Electric motors consume about half of the world’s electricity. This new efficient motor design replaces the copper wire and laminated iron core found in conventional motors with a printed circuit board stator, making the motor smaller, lighter and more efficient. The coreless motor is combined with a programmable variable-frequency drive and a controller that provides real-time monitoring and cloud-based connectivity. 

Snap-on Window Insulation Panels, WexEnergy (Rochester, NY) Windows, especially single-pane windows, are the weakest energy-efficiency link in the building envelope. They account for approximately 39 percent of the energy used annually to heat commercial buildings in the U.S. and 28 percent of the energy used to cool them. Snap-on window insulation panels improve the thermal performance of windows, while maintaining window transparency and operability.
