Dynamic Application


Hotel Ella

Under new ownership, the historic building known as Mansion at Judges’ Hill recently transformed into Hotel Ella. The building, located near the University of Texas campus in Austin, went through a multi-million dollar renovation into a boutique hotel that is named after the building’s original owner, Ella Wooten. DXS was named basis of design for the project, retrofitting the common areas with 10 tons of Daikin heat recovery. The ductless units that Daikin offers integrated nicely with the existing architecture of the historic building. As a bonus, the increased energy efficiency and use of VRF qualified the owner for Austin Energy rebates.
