Active beams from Price were the ideal solution for this project. Water is several times more efficient than air at transporting thermal energy,
and by selecting a hydronic solution such as beams, the engineer was able to increase the energy efficiency of the system by reducing the size of
the air handler and ductwork required to service the space. This was a more efficient alternative to the all-air system that had been implemented
several years earlier.
The use of smaller piping in active beam systems also addressed the challenge of extremely low floor-to-floor heights and restricted plenum space
by eliminating the need for large ductwork.
Humidity was not an issue in the space, as this was easily controlled through the primary air handler, ensuring that only air with the desired
moisture level would be delivered to the space. Moisture sensors were also incorporated into the Price Active Beams.
Mechanical systems in a compounding pharmacy typically need to meet the requirements of USP 797 and ISO 14644. As the pharmacy at Memorial Hospital
used glove boxes to complete the compounding process, HEPA filtration was not a requirement. However, a room within the pharmacy was set aside for
future compounding use, therefore it was designed with HEPA filtered fan powered terminals to meet industry regulations.
The active beam system has been running for over a year and is described as “shockingly comfortable” by the team, who is considering utilizing active
beams in other areas of the hospital that are planned for renovation.
