Callaway House

  • Project Location: Austin, TX
  • Owner/Client: American Campus Communities
  • Project Description:

A new off-campus freshman residence opened just one block from The University of Texas in August of 2013. The Callaway House comes in at 17 stories, 585,000 square feet and features 219 fully-furnished units. This premier facility features a secure building entrance, 24 hour courtesy desk, recreational lounge, on-site dining, private dining, study rooms, reserved garage parking with controlled access, fitness center, rooftop pool, and a premium efficiency Daikin VRV/VRF HVAC system provided by DXS.

The goal of the project was to incorporate a quiet system for the student housing while also providing enough energy efficiency to save the facility money. As basis of design, DXS was able to meet all these goals due to the VRF system’s high efficiency and flexibility and the proven success of VRF on other high rise projects.

Installed were 20 Daikin heat recovery units and four heat pump units, totaling 345 tons of heat recovery and 36 tons of heat pump. These units were installed on floors 7-17 in all the living spaces and study rooms. Plus, 252 ducted fan coil units were installed throughout the facility and an Intelligent Touch Manager for remote access for the maintenance manager to monitor the operation of the equipment.

Multi-Family Key Considerations

In Europe and Asia, where cities are densely populated and high-rise apartment buildings are the norm, VRF air conditioning systems represent 50 percent of the multi-family market. As development space in North American urban areas becomes more valuable and as consumers here become more energy efficiency-minded, VRF technology is now the preferred choice of many multi-family building developers.

VRF systems offer architects and engineers with a competitive alternative to chilled water and split systems. DXS partners with developers who are attracted to VRF’s energy efficiency, ease of maintenance and its long life. And we work with engineers to customize our products, such as designing a system that provides both high-efficiency heat and air conditioning.

Key Considerations

  • Energy efficient; lower utility rates are passed through to tenants and owners
  • Opportunity to reduce overall building construction cost
  • A 20+-year lifespan on mechanical system compared to 10 to 15 years for traditional systems
  • Ability to handle temperature control for hundreds of small spaces
  • Heats and cools buildings varying in height from single story to high-rise more effectively than conventional AC systems
  • DXS onsite at five key junctures: onsite training prior to installation, quality control checks during installation, during start-up, 30 days after commissioning for building owner verification, and ongoing training for staff
  • Fast, dependable service and maintenance support after installation
  • Complete inventory of parts and equipment locally stocked
