About this file
This document contains mechanical calculations for repairing Military Working Dog Kennels at Facility 1030 on Joint Base Langley-Eustis in Hampton, Virginia, prepared by Vansant & Gusler Consulting Engineers on July 22, 2025. The mechanical calculations focus on outside air requirements and ventilation specifications for two dog kennels, with calculations demonstrating 12 air changes per hour based on the Design Guide for Military Working Dog Facilities from August 5, 2003. The calculations detail room volumes, ventilation rates, and cooling/heating loads for Dog Kennel 01 (1,065 sq ft) and Dog Kennel 02 (925 sq ft), utilizing a Dedicated Outdoor Air System (DOAS) with cooling and heating coils. The system includes two fans and is designed to manage temperature and air quality for the kennel spaces, with peak cooling and heating load analyses provided for different times of the year.

MUHJ 24-4024
July 22, 2025
Outside Air Requirements:
Per Design Guide for Military Working Dog Facilities, 5 Aug. 2003, the total air changes in the kennel area should be 10-15 air changes per hour.
• A total of 12 air changes per hour will be chosen to serve Facility 1030.
