Project Files: VRF Works for LifeWorksCompany: Direct Expansion Solutions (DXS)

Customer: LifeWorks (Austin, Texas)

Installation: A six-unit, 96-ton Daikin Variable-Refrigerant Volume (VRV) heat recovery system; a 6-ton Daikin VRV heat pump; Daikin Intelligent Touch Controller (iTouch) with start and stop control for ancillary equipment; and 42 indoor fan coil units.

Completion: Early 2012

Objective: To provide energy-efficient HVAC solutions that reduce the client’s energy costs while providing flexible cooling/heating options to a multi-tenant/multiuse facility.

Work Completed: The facility for LifeWorks, which houses the Austin, Texas, nonprofit organization as well as two other organizations, often operates late into the evenings and on weekends, so it is crucial that the building be equipped with an HVAC system that could adjust to the changing needs in various areas of the building. Energy savings were a high priority in keeping operating costs down. Variable-refrigerant flow (VRF) technology was selected for its multiple benefits, including energy efficiency and the ability to control the flow of refrigerant throughout the building, which allowed users to customize the temperature in different zones of the building to fit their needs. The ductless installation also prevents heat loss/gain for additional savings. The installation of the VRF equipment is projected to result in a 30 percent savings for the organization.

Quote: “Organizations dedicated to serving those in need have to identify all possible ways to reduce operational costs. We were pleased to provide LifeWorks with specialized HVAC solutions that maximize efficiency, minimize energy costs, and help the organization reach its sustainable goals set forth by the Austin Green Build program.” — Keith McLaughlin, principal, DXS
