Engineered to the
Code Book.
A working summary of the building, electrical, environmental, and industry standards the NSV reference design is engineered to meet.
Underground Construction
International Building Code
The vault enclosure is designed and stamped to IBC requirements for occupancy class, fire-resistance ratings, and structural load (live, dead, and seismic) for the local jurisdiction.
Seismic & Wind Loads
Designed to ASCE 7 site-specific seismic and wind-load criteria. Below-grade placement provides inherent seismic advantage compared to above-grade equipment yards.
Permit-Ready Drawings
Stamped structural, MEP, and civil drawings are submitted to the local Authority Having Jurisdiction during standard development permitting — no special process required.
Power, Interconnect, and Backup
National Electrical Code
All vault electrical systems comply with the current NEC adopted in the deployment jurisdiction, including conductor sizing, grounding, overcurrent protection, and arc-flash labeling.
Grid Interconnect
BESS interconnect with the utility grid follows IEEE 1547 for distributed energy resources — including anti-islanding protection, voltage/frequency response, and required disconnect coordination with the utility.
Battery Energy Storage
The Battery Energy Storage System uses UL 9540-certified equipment with thermal runaway protection and is sited per NFPA 855 separation and ventilation requirements.
Thermal Loop, Fluid, and Life Safety
International Mechanical Code
The thermal distribution loop, hydronic snow-melt manifolds, and absorption chiller integration are designed and inspected to the current IMC and any local amendments.
Information Technology Equipment
The vault is designed to NFPA 75 standards for the protection of information technology equipment, including separation, fire detection, and suppression strategy appropriate for an immersion-cooled environment.
Non-Flammable, Non-Toxic
The two-phase immersion fluid is a non-flammable, non-toxic, non-conductive engineered fluid with decades of use in industrial applications. SDS sheets are provided to the local fire marshal during permitting.
Sustainability Certifications
Energy & Atmosphere Credits
By recovering nearly 100% of compute thermal output to displace gas-fired building heat, NSV directly contributes to LEED Energy & Atmosphere credits without renewable energy certificates or carbon offsets.
Building Certification
The thermal-reuse load profile improves the building's whole-building energy intensity, supporting ENERGY STAR certification for multifamily and commercial assets.
Scope 1 & 2 Reductions
Boiler displacement directly reduces Scope 1 (combustion) emissions; closed-loop thermal reuse reduces Scope 2 (purchased electricity) for heating loads. Both are documentable for ESG reporting.
Underwriter-Friendly by Design
Hydronic Snow Melt Reduces Claims
Automated, sensor-driven snow melt eliminates the largest source of premises liability claims in cold-climate properties. Underwriters typically recognize this as a measurable risk reduction.
No Combustion On-Site
Eliminating the gas boiler removes a significant property and liability exposure. No combustion equipment, no fuel storage, no associated permit and inspection burden.
Reduced External Attack Surface
On-premise AI and tenant-isolated workloads dramatically reduce the cyber attack surface compared to cloud-dependent smart-building systems.
