Joined by Gal Judah, Area Sales Manager at Georg Fischer, the conversation dives into the evolving role of LSS in zoos, aquariums, and aquatic facilities—where lighting, air quality, controls, and integrated infrastructure are just as critical as water.

Gal shares his unique path into the LSS world through the skilled trades, offering insight into how electrical systems, advanced lighting technologies, piping solutions, and automation all intersect to support animal health, welfare, and operational reliability. The episode highlights how collaboration between operators, engineers, vendors, and designers is reshaping how facilities are built, upgraded, and maintained.

Listeners will gain perspective on:

• How lighting and air systems directly impact aquatic and terrestrial habitats

• The growing technical skill set required of today's LSS professionals

• Why integrated system design is essential for long-term sustainability

• The role of manufacturers and vendors in advancing LSS innovation

Whether you work in aquatic life support, zoo and aquarium operations, engineering, or facility management, this episode offers valuable insights into where the industry is headed and how rethinking LSS can lead to healthier animals and smarter facilities.
