Refer to Part 4 Section D30 for performance requirements of the building elements included in the HVAC system.

SYSTEM DESCRIPTION

The factory integrated Battery Energy Storage System (BESS) must be provided with DX split system to provide cooling to attain the following objectives: 24/7 continuous sustainment of critical infrastructure environmental condition, indoor air quality, acceptable noise levels, energy efficiency, reliable operation, and ease of maintenance. Design and install in accordance with UFC 3-401-01 MECHANICAL ENGINEERING, UFC 3-410-04 Industrial Ventilation, UFC 3-410-01 Heating, Ventilating, and Air Conditioning Systems, UFC 3-520-05 Stationary and Mission Batteries and all Mechanical Engineering and related UFCs. These UFCs incorporate provisions of the International Code Council's International Mechanical Code (IMC) and ASHRAE design guidance with supplemental requirements.

A dedicated and independent cooling system shall be provided for each pre-factory battery storage container. This system must be separate from the building’s HVAC system and designed specifically to maintain a consistent ambient temperature of 65°F (18°C), or as per the manufacturer’s specified temperature requirements for optimal performance and longevity of the battery storage system. The cooling system should be capable of efficiently regulating the temperature within the specified range, taking into consideration the heat generated by the batteries during charging and discharging cycles.

Additionally, the system must include necessary monitoring and control mechanisms to ensure stable operating conditions, prevent overheating, and comply with safety and performance standards for the battery storage system. Provide a proper ventilation system to avoid the buildup of heat and gases generated by the batteries, Additionally, provide a Hydrogen and Gas Detection System to continuously monitor and detect the presence of hazardous gases, including hydrogen, within the battery energy storage system. This system is critical for ensuring the safety of the installation, as it helps identify potential risks such as gas leaks or the buildup of flammable gases. Early detection allows for prompt mitigation actions, reducing the risk of fire, explosion, or system failure, thereby safeguarding both personnel and equipment.

Provide BESS scalable, factory integrated and certify with all safety features, ready to “Plug-and-Play”. Provide factory installed interior wiring and connections for Equipment, Auxiliary Equipment, AC and DC Distribution, Lighting and Branch Wiring, HVAC, Fire Alarm, Communications, etc. including accessories and devices as necessary and required for a complete usable system.

Provide BESS Facility Related Control Systems (FRCS) capable of remote monitoring and control.

The BESS FRCS equipment will be house in a separate equipment booth. Provide interior wiring and connections for Equipment, Lighting and Branch Wiring, HVAC, Communications, etc. including accessories and devices as necessary and required for a complete usable system.

GENERAL SYSTEM REQUIREMENTS
