Merwyn Patrick helped Sprint to identify potential energy saving opportunities in the HVAC systems used in the Sprint Network Sites, also known as Switches. These sites have implemented energy efficient systems like hot aisle/cold aisle systems and variable speed drives, but Sprint was looking for a more holistic approach for site cooling.
Patrick worked with Sprint’s Network Planning Manager, John Holmes, and Network Engineer, Rob Schroeder, to complete an energy audit, research the HVAC systems used in the Switches and develop various implementation recommendations such as free air cooling, humidification for free cooling, water economizers and chiller maintenance checkups for energy saving.
Although the proposals made by Patrick are yet to be implemented, free air cooling, if applied, can alone save up to $1.5 million and 10,000 metric tons of carbon annually. Additionally, chiller maintenance efficiency and increased deployment of cooling towers can generate savings up to $1 million.
