Value Delivered
ECM provided cooling equipment renovation services at buildings across North America and India for a Fortune 500 property management company. We developed a seven-step process for protecting the existing equipment against future corrosion and restoring it to near its original efficiency, with an expected payback of less than three years.
We developed a creative, customized solution capable of rolling out across a global building portfolio with equipment varying in age and condition. Our team worked hard to minimize impact on building occupants so that the client could maintain regular day-to-day operations.
In multiple states, as well as Canada and India, the client renovated over 27,000 tons of cooling equipment. The projects are projected to generate energy savings of well over $1.5 million.
Client Objectives
