Twin Oaks Branch Library

Encotech provided the Mechanical, Electrical and Plumbing design work for this new single-story 10,000 s.f. City of Austin Branch Library. The Twin Oaks Branch Library’s design is a response to its location in an established and eclectic South Austin neighborhood. The facility includes a large main reading area, young adult and children’s reading rooms, staff offices and support spaces, as well as an outdoor amphitheater.

A variety of sustainable design measures were employed for this building, including a photovoltaic system, rainwater collection system, and a daylight responsive lighting control system. Design also included full concealment of the ductwork in a building with mostly exposed structure, a thermal chimney at the vestibule entrance, and strict ventilation and humidity control standards per Austin Public Library requirements. Encotech’s Plumbing design incorporated plumbing fixtures with dual-feature low consumption flush valves, water closet, occupancy faucet for a lavatory and direct vent gas water heater.

The electrical power distribution system utilized separate common power and technology power systems, served by a new pad mounted utility transformer, with contributions from a solar power system. Also included were connections for a mobile emergency power system for the server room.

Encotech’s Mechanical design included a HVAC system using 100% outdoor side air units with hot gas reheat and multi-stage gas heat. The system also utilizes a residential style, high efficiency (16 SEER), variable speed, 2 stage cooling DX split system. The system also features a condensate drain to rain water collection system. The controls feature a full Direct Control System by Trane Tracker systems. All control systems can be remotely accessed through dial-up or internet access.
