Total building efficiency and limited equipment space were the two primary challenges on this Austin project. This building was designed while working with the engineer on another project, RiverSouth. During the RiverSouth project, we proved that Daikin AWV air cooled screw chillers were efficient enough to both satisfy Austin’s above-and-beyond efficiency requirements and be part of a building with a LEED Gold certification. That made the choice to use Daikin AWV chillers on this project an easy one. We still had to contend with Austin’s efficiency requirements and had no problem complying with them.
Fitting equipment in the allocated space after the architect’s hands over a preliminary design to an engineer is often a challenge. This project was no exception. The space designated for chillers on the roof was very tight and took a lot of coordination to meet performance and service clearances.
The mechanical rooms as originally designed were so small the engineer had to push back and ask for more space. Even then the air handling units had to be as compact as possible. This was achieved using Daikin’s EC fan arrays, allowing for the shortest unit length achievable.
Next time you’re at the Domain in Austin, look for the tallest building around and you’ll see proof of Daikin and HTS having delivered real success.
