About this file
This document is a Mechanical Design Criteria section from Construction Documents for a Department of Veterans Affairs project at Wichita VA Medical Center in Wichita, Kansas (VA Project No. 589A7-23-305), dated May 17, 2024. The project involves preparing a site for Choice Dining Equipment installation.
The mechanical design criteria establish applicable standards and codes governing the project, including ASHRAE standards for ventilation, indoor air quality, mechanical refrigeration, and energy efficiency; the International Mechanical and Plumbing Codes; Americans with Disabilities Act requirements; NFPA standards for electrical, fire alarm, sprinkler systems, air-conditioning/ventilation systems, and health care facilities; VA-specific design manuals for physical security, resiliency, and fire protection; and publications from ANSI, ASME, and ASTM. Design conditions specify an elevation of 1,321 feet above mean sea level at a latitude of 37.65°N and longitude of 92.43°W. Winter heating design calls for outside air at 7.9°F with 31.4 MPH winds and inside conditions of 70°F at 35% relative humidity, while summer cooling design requires outside air at 100.5°F dry bulb and 73.8°F mean coincident wet bulb with inside conditions of 75°F at 50% relative humidity. Break rooms and office spaces must maintain 75°F in summer and 70°F in winter with 30-60% humidity, require 4 air changes per hour, and demand 2 air changes per hour of outdoor air.
