Southwest ISD Legacy High School

This $60 million project includes a new 430,000 square foot high school for 3,000 students in Southwest ISD. Legacy High School was part of a master plan to provide for the potential needs of the growing district by allowing for future additions in both the capacity of the floor plan, as well as the MEP systems. A unique open corridor, which spans the length of the school, creates an open concept floor plan with adjoining work spaces designed so students can easily work in groups large or small. MEP Engineering, Inc. was hired by project architect, Pfluger & Associates Architects, and provided the following:

  • Combination of rooftop DX units with gas heat and chilled water outside air pretreatment units with enthalpy heat wheels and supplemental DX cooling.
  • All classrooms were supplied with minimum 15 CFM of outside air per student to comply with the latest ASHRAE recommendations for indoor air quality.
  • Plumbing systems contained electronic sensors on water closets, urinals and lavatories to conserve water and ensure sanitation.
  • Electrical systems included classroom, LED common area lighting, athletic field lighting (football stadium, baseball, softball and tennis), power distribution, cable tray systems for all data and communication systems and fire alarm systems.
  • Unique HVAC systems included athletic dehumidification units/100% outside air systems, welding exhaust systems, shop compressed air systems and laboratory fume hood exhaust systems.

Working in conjuncture with the design team, MEP created a design that resulted $5 million in savings though value engineering. Legacy High School opened to students in the fall of 2017.
