PROBLEM
As one of the only global planning, engineering, and construction management firms that’s also an accredited ESCO, AECOM is sought after to develop and execute comprehensive energy-efficiency projects worldwide. When they recently began a project for Sutter Health hospital in San Francisco, the ESCO realized the building’s patchworked window film was hampering critical heat-gain measurements. Energy measurement is a highly specialized industry, but AECOM knew one of the few companies with the hightech tools to accurately and effectively perform glazingrelated energy modeling: NGS Films and Graphics. “We have meters that go directly on the glass to measure the solar heat-gain coefficient, visible light transmittance, infrared transmission – all the variables you need to know,” explained James Beale, Managing Partner at NGS. “These tools accurately show existing performance, so you understand how much room you have to improve.”
