Eureka High School knew there just had to be a better way to condition the Industrial Arts wing of the school. The old system and its air distribution system were failing and just did not have the flexibility of zoning that the multi-use facility needed.
They shared this problem with Arthur Floyd of Glenn Construction who represents the construction management for the school, and he contacted Air Masters, who had done successful projects at the school for him before.
The old system was very dysfunctional and inefficient, with many complaints of rooms that were either too warm or too cold. Air Masters designed a 30-ton Trane VAV roof-top unit with seven independent zones with fan terminal units and electric heat to meet these needs.
This approach allows the capability of simultaneous heating and cooling needs of this wing. All new supply and return air ductwork, diffusers, and grilles were installed as part of this project. The system was connected to the existing Direct Digital Controls (DDC) network.
A new make-up air system for the metal and wood shop was also installed. The new make-up air system is now interlocked with the existing shop hoods to help bring the school up to present codes. The new rooftop air conditioner brings in fresh ventilation air for the classrooms and provides “free” winter cooling to meet the demands of the rooms that need year-round cooling and to meet today’s standards.
Saint Louis County takes a hard look at schools that upgrade their systems to be sure they meet he new International Mechanical Code.
It takes a lot of coordination between everyone involved to make everything go smoothly. All the work had to be done during the school vacation so it would be ready for the start of the new school year. Like projects done before, it was on time and within budget.
The Industrial Arts wing now has a “state-of-the-art” mechanical system that allows greater flexibility of zone control for optimum performance and lower energy costs.
