Ultra quiet, energy efficient hybrid heating solution beats out competition for luxury condominiums – supports LEED® certification Issues Outcome Tishman Speyer, a major real estate developer, specified highly efficient and ultra low-noise water source heat pump (WSHP) units for its Lumina luxury condominium property. Located near the Embarcadero waterfront and offering views of San Francisco Bay, when completed, Lumina will accommodate 656 units spanning two mid-rise buildings and two high-rise towers. In a laboratory sound test that simulated the floor plans, the WSHPs beat another manufacturer’s offering in a similar configuration. “The units performed well to acoustical testing partly due to Daikin Applied’s advanced control system which allowed for variable CFM airflow outputs,” says Fred Parker, Daikin Applied representative with Norman S. Wright Mechanical in San Jose. Because each building makes generous use of windows, in order to meet California’s Building Energy Efficiency Standards (specifically Title 24 energy compliance), and for expected LEED® certification, remaining design elements required high energy efficiency. The first WSHPS, among a total of 761, will be delivered to the job site in November 2014 for the first mid-rise tower, scheduled to open in 2015. The remaining buildings will take occupancy in 2016. Once all Lumina buildings are in service, the innovation of the cabinet WSHPs are expected to contribute to LEED Silver Certification for new construction. Daikin Applied developed a new SmartSource WSHP model featuring supplemental hydronic hot water coils placed on the top of each unit. “The hybrid units are energy efficient in the cooling mode but extra efficient in the heating mode,” says Steve Poe, P.E., engineer of record for the project with Critchfield Mechanical, Inc. (CMI) in San Jose. “The WSHPs not only meet the developer’s requirements for energy efficiency and low noise but are ideally suited to the San Francisco climate which requires heating almost every night and often during seasonal cool days.” Adds Craig Fischbach, WSHP sales manager with Daikin Applied: “In this location, it will be less expensive to heat the residences with the hydronic hot water coil, versus the heat pump function using the compressor.” In addition to low utility bills, Lumina residents will have the option to control their system using a Wi-Fi enabled thermostat. ©2014 Daikin Applied • www.DaikinApplied.com • CS-1029 Image courtesy Tishman Speyer Solution Once installed, the hydronic hot-water coils do not require use of an electrical compressor to supply heat, providing for extremely quiet tenant operation.
