Fortune 100 Executive and Renewable Energy Innovator Joins SolarWindow

Columbia, MD – August 9, 2017 – SolarWindow Technologies, Inc. (OTCQB: WNDW), developer of electricity-generating windows for tall towers and skyscrapers, is pleased to announce the Advisory Board appointment of Mr. David Gralnik, an accomplished senior executive with worldwide renewable energy experience at multiple Fortune 100 companies, including Edison Energy, LLC (Edison), Jones Lang LaSalle (JLL), Honeywell, PG&E and Johnson Controls.

Mr. David Gralnik, Advisor SolarWindow Technologies, Inc.

Mr. Gralnik joins a growing SolarWindow team which has expertise in: joint-ventures and licensing; large scale energy-products manufacturing; project finance; glass and energy products sales and marketing. He brings 30 years’ experience in 14 countries, negotiating the purchase and sale of conventional and renewable energy systems for large commercial buildings such as shopping centers, institutional clients, ex-military bases, and skyscrapers.

Consuming almost 40% of all the electricity generated in the U.S., these commercial buildings are ideal customers for the company’s electricity-generating windows, which could reduce electricity demand by 30%-50% in tall towers and have a one-year financial payback, according to independently-validated engineering modeling.

“As we’ll highlight in our upcoming September 7th production update, the specific expertise of Mr. Gralnik will help us market our electricity-generating windows to the estimated 5 million commercial buildings in the U.S. and eventually to the tens of millions of commercial buildings around the world,” stated Mr. John Conklin, President and CEO of SolarWindow Technologies, Inc.

From initiating and closing a first-of-it-kind $300 million biogas contract with one of the nation’s largest utilities (while at Honeywell International), to advising on energy microgrid installations for retired military bases and renewable energy strategies for major technology companies (while at Edison and JLL), Mr. Gralnik is a highly regarded and respected renewable energy executive with over 30 years of experience.

As Senior Vice President, Global Director of Renewable Energy Services at JLL, he founded and expanded their renewable energy advisory services practice to 12 countries and won the da Vinci Award for Innovation. JLL is an international leader in providing advisory and real estate services that include the purchase, sale, and management of commercial real estate and iconic skyscrapers, with over 70,000 employees and a 250-year strong history in 80 countries.

Mr. Gralnik holds a B.A. in business administration from California State University at Northridge, is Six Sigma certified, and has been quoted in numerous articles and presented at the World Energy Engineering Conference, among others.

SolarWindow Technologies, Inc. creates transparent electricity-generating liquid coatings. When applied to glass or plastics, these coatings convert passive windows and other materials into electricity generators under natural, artificial, low, shaded, and even reflected light conditions.

Our liquid coating technology has been presented to members of the U.S. Congress and received recognition in numerous industry publications. Our SolarWindow™ technology may generate 50-times the power of a conventional rooftop solar system and may achieve a one-year payback when installed on all four sides of a 50-story building, according to independently-validated power and financial modeling.

Power and Financial Model Disclaimer

The company's Proprietary Power Production & Financial Model (Power & Financial Model) uses photovoltaic (PV) modeling calculations, which are consistent with renewable energy practitioner standards for assessing, evaluating and estimating renewable energy for a PV project. The Power & Financial Model estimator takes into consideration building geographic location, solar radiation for flat-plate collectors (SolarWindow™ irradiance is derated to account for 360 degrees building orientation and vertical installation), climate zone energy use and generalized skyscraper building characteristics when estimating PV power and energy production, and carbon dioxide equivalents. Actual power, energy production and carbon dioxide equivalents modeled may vary based upon building-to-building situational characteristics and varying installation methodologies.
