N ENG NEERSR <br /> —JENW.IF <br /> ....... <br /> PROJECT 2024-0772—Clare's Place: Ventilation Revisions <br /> EXECUTIVE SUMMARY <br /> NEBB Statement <br /> This project has been balanced per plans and specifications using the National Environmental Balancing <br /> Bureau(NEBB) standards and procedures, and in accordance with the approved Test and Balance Strategy. <br /> All systems were balanced within specified tolerances. <br /> All air systems have been inspected and measured for fan operating data, operating amperage, voltage, <br /> rotation, RPM, and operating static pressure. <br /> Scope of Work <br /> The scope of work for this project includes the Testing, Adjusting, and Balance of three (3) Intake Fans and <br /> three (3) Exhaust Fans, setting only the total airflows for each unit. The Grilles, Registers, and Diffusers <br /> (GRD's)were excluded from the SOW due to occupancy. <br /> The Balancing Tolerances for Systems included in the SOW are specified for this project are as follows: <br /> • Supply and Exhaust Fans and Equipment with Fans: ±10% <br /> Air Systems Summary <br /> Fan Units: Intake Fans (IF) & Exhaust Fans (EF) <br /> The fans were checked for proper operation, rotation, amps, and volts. The fans are balanced to meet design <br /> flows. GRD balance was excluded from SOW. The fans were set by total airflow traverse using the detached <br /> controller to plug into the units and set the fan RPM. A fan summary is below.
