The Sovereign is a 45 storey mixed-use tower, located on the northeast corner of Willingdon and Kingsway, making it Burnaby’s tallest tower. The project features 100,000 square feet of commercial space including retail and restaurants, 169 rooms of the “Elements” hotel, and 202 market condominiums. The Sovereign is located near shopping centers including Metropolis at Metrotown, and close proximity to public transportation SkyTrain stations. This project has several unique features to the mechanical systems. The lower retail/commercial floors and hotel floors (levels 1-18) have vertical water source heat pumps for room conditioning. The upper condominium floors (levels 20-45), use four pipe fan coils. The 19th floor is an interstitial floor which houses the heat recovery and cooling plant mechanical systems.
