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.
