Our relationship with The Episcopal School of Dallas began in 2008, and we are now working on our fourth project for The School. Once completed, the $36.5M Lower School project will boast the following customized spaces: •Grade-level homerooms connected by a shared collaboration space called a neighborhood •A “Discovery Commons” on each floor includes a library, media, and spaces for studying, collaborating, researching, etc. •Two science labs along with creative spaces that feed the students’ creativity •Library resources throughout the building •A community staircase that allows for gatherings, small group work, impromptu performances, etc. The MEP design and installation comply with all applicable codes and the Dallas Green Building guidelines. Solar water heating will be used, and rainwater will be harvested to irrigate plantings for the science classroom. We evaluated the pros and cons of using a chilled water system, VRF system, or DX Rooftop unit system for the building. It was decided to proceed with a VRF system for the entire building due to its energy efficiency and ability to support multiple zones. The VRF system is quiet and can be easily integrated into most building decorum or hidden altogether - indoors or outdoors. A complete DDC building automation system was designed and installed as part of this project and connected back to the central campus control system. A new 277/480-volt electrical system was designed for this new building, and half the building was built as a tornado shelter, per requirements of ICC-500. An emergency generator was also provided for life safety requirements on this project.
