NEXT’s PV Windows Show Significant Energy Efficiency Promise

NEXT Energy Technologies Inc. led a multi-year photovoltaic (PV) window project as part of the Wells Fargo Innovation Incubator (IN2). Results show NEXT’s technology could lower the solar heat gain coefficient (SHGC) from an otherwise equal window to below .20.

IN2 is a renewable technology initiative focused on scalable solutions to reduce the energy impact of commercial buildings. Wells Fargo Foundation and the U.S. Department of Energy’s National Renewable Energy Laboratory co-manage the program.

NEXT’s PV technology uses proprietary organic semiconducting materials that are earth-abundant and low-cost. This material is coated uniformly onto the glass as an ink, enabling the surface to harvest the sun’s light and convert it into electricity rather than heat.

Crystal Windows Completes Solar Installation

Crystal Window & Door Systems installed a solar electricity generation rooftop system at its headquarters and main production facility in Queens, N.Y. The nearly 1-megawatt system includes more than 2,300 solar panels and could generate nearly one million kW-h annually. This would offset about 35% of the manufacturer’s overall electricity needs.

Crystal worked with Amergy Solar on a 25-year Power Purchase Agreement. Amergy Solar is a New York-New Jersey regional provider of solar energy generation systems for commercial and residential properties.

A custom racking and bedding system was designed and fabricated for the company’s solar panels, with a 10-degree slope and a non-roof-penetrating connection system. The system uses 2,320 solar panels, associated racks and 18 electrical power inverters.

Louisiana Passes Energy Efficiency Codes

A new Louisiana law will help improve energy efficiency codes throughout the state.

Louisiana Gov. John Bel Edwards signed the new law in June. It transfers the responsibility of commercial energy code enforcement from the state government to third-party providers and local municipal/parish governments.

The Louisiana legislature also unanimously approved statewide adoption of the 2021 International Energy Conservation Code (IECC) and the 2021 International Residential Code (IRC) Chapter 11 Energy Efficiency.

Its adoption follows the U.S. Department of Energy’s introduction of a grant program that assists with updating energy codes. The Energy Code Implementation Program was established in the Infrastructure Investment and Jobs Act and provides $225 million over five years.
