RWB Wins 2020 ASHRAE Dallas Technology Award for Braswell High School Design

Braswell High School in Aubrey, TX - Exterior

Project Moves on to Regional Competition

This week, the Dallas Chapter of ASHRAE recognized RWB Consulting Engineers for exceptional HVAC design. Denton ISD’s Ray Braswell High School earned the chapter’s Technology Award for New Educational Facilities.

The ASHRAE Technology Awards recognize outstanding achievement in mechanical system design and operation. While other programs such as LEED recognize buildings for minimizing energy usage, the Technology Award celebrates designs with a holistic approach.

Winners of the technology award demonstrate competency and success in applying effective strategies for:

  • Energy management
  • Indoor air quality
  • Thermal comfort
  • Operational cost effectiveness
  • Innovation
  • Operation and maintenance
  • Environmental impact

RWB Consulting Engineers is well-known for their experience in successful K-12 MEP design, with Braswell High School being particularly exemplary.

Leaders of the Dallas Chapter presented the award on Wednesday, February 12th. As seen on the photo below, several members of the RWB leadership team were on-hand to accept the award.

In Little Elm, Texas, this new facility for over 2,600 students in 9-12th grade opened in August 2016.

The HVAC design for Braswell High School features a geothermal system with over 1,100 wells serving 239 heat pumps. With so many wells, our team broke the geothermal system up into smaller well fields that serve different areas of the building. Ground source heat pumps were piped in parallel for redundancy. And three-way valves installed at the extremity of each lunch ensure proper water flow and temperature during operation.

Our team used an innovative humidity control system in high-latent areas like the auditorium, gymnasium, and cafeteria. Using a unique hot gas reheat system, the air in these spaces can be dehumidified without having to reject any heat to the associated well field. In addition, energy recovery ventilators (ERVs) were used in tandem with carbon dioxide sensors to provide the precise amount of fresh air to spaces. Both design strategies contribute to improved occupant comfort and reduced energy consumption.

This isn’t the first time that the design team for Braswell High School has been recognized. In 2017, the Texas Association of School Administrators and Texas Association of School Board’s Exhibit of School Architecture awarded architecture firm VLK with the Design and Value award.



The Dallas Chapter of ASHRAE accepts nominations each year for their Technology Award competition. They can recognize multiple MEP engineering firms in 19 different categories as shown in the bulleted list below below.

As the winner of the Chapter award, this project will move to the Regional competition. RWB faces competition from other ASHRAE Chapters in Texas, Oklahoma, Arkansas, and Mexico. The regional judging committee will announce the winner of the region competition during the Chapter Regional Conference in April 2020.
