Company
Established in 1918, Denver Water in Colorado, USA is the state’s largest and oldest water utility company. It provides water to over 1.5 million people in the city of Denver and its surrounding suburbs.
Challenge
Embarking on the redevelopment of its operations complex, Denver Water took the opportunity to develop a site that better served its community. Improved efficiencies, functionality as well as more secure operations were key criteria, but Denver Water also wanted to ensure that sustainability was a key factor too.
The water utility’s operations had been located on the site since 1881.The buildings in the complex were outdated, inefficient, and inadequate to support future demands of providing water service the community. The overall goal was to build a state-of-the art modern facility that improved the efficiency and functionality of all operations.
Solution
As the business wanted to be carbon friendly, they specified the installation of an Aermec NRL2250 heat pump which provides 1,116 MBH to heat the inlet city water and is then piped to four Aermec NRK0700 heat pumps.
Aermec’s NRK units were optimised to operate at greater efficiencies at low temperatures (down to -4°F) and use a gas injection compressor that enables the heat pump to produce hotter water than a standard heat pump (up to 149°F).
Result
The units boost the hot water from the heat pump, which produces great efficiency and higher temperature water, helping to meet the company’s sustainability and efficiency goals.
Denver Water’s complex was designed to incorporate LEED certification (Leadership in Energy and Environmental Design) and is the world’s most widely used green building rating system (equivalent to the UK’s BREEAM rating) and presents educational demonstrations of net zero energy and leading-edge concepts.
The facility will feature educational components about water and its efficient use. A large part of this can be attributed to Aermec’s heat pumps.
