FAQ Schema

Frequently Asked Questions About Energy Storage & BESS

Find answers to common questions about energy storage cabinets, outdoor cabinets, battery systems, and BESS solutions.

What are the mandatory minimums for duct insulation?

The mandatory minimums for duct insulation are discussed in Section 4.4.1.1. There is a prescriptive requirement for ducted systems that have cooling and a CFI ventilation system to have the fan efficacy verified. This can be opted out using the performance approach.

Does a duct system need to be airtight?

CMC E502.4.2 requires that all joints, seams, and penetrations of duct systems must be made airtight by means of mastics, gasketing, or other means. For duct systems located entirely in conditioned space, the ducts do not require insulation.

How much duct leakage should a duct system have?

For single-family dwellings and townhouses where the air-handling unit is installed and ducts are connected directly to the air handler, the total leakage of the duct system must be 5 percent or less of the nominal system air handler airflow.

How do I install air ducts?

Here's how to install air ducts effectively: Identify the airflow path: Determine the direction of airflow within the container. Hot air generated by the batteries should be directed away from the battery modules and expelled outside the container. Install ventilation fans: Place ventilation fans strategically to ensure sufficient airflow.
