DM Engineers PLLC was retained to upgrade the site’s Natatorium HVAC systems by implementing the new temperature and humidity control technology developed by Efficient Air Systems Inc. The primary focus was to control temperature and humidity while decreasing the high levels of tri-chloramine build-up in the room.
The proposed system implemented new technology that provides more room air changes while maintaining an energy-efficient system through a closed-loop heat pipe and without a need to use mechanical cooling.
Scope of work included the selection of the new dedicated outdoor air system, retrofit to the existing ductwork configuration, natural gas connection for the unit-mounted furnace, fire alarm device relocations, powerpoint of connection coordination, structural reinforcement design, ventilation index verification and coordination for in house Direct Digital Control (DDC).
DM Engineers worked side-by-side with the mechanical and electrical contractor to coordinate the phasing plan and rigging logistics for the site. Additionally, DM Engineers spearheaded the process with NYC DOB Office of Technical Certification and Research (OTCR) technical certification in order to attain approval on the newly proposed equipment.
