A. General Requirements

1. Codes and Standards:

? Information contained in this Module is intended to set

minimum mechanical system requirements and is not intended to provide complete design solutions to project specific situations.

? Comply with the more stringent of governing laws,

applicable governing codes and regulations, and these Design Standards.

? Refer enhancements, deviations, and conflicts between

design standards to Marriott A&C Engineering for resolution.

? FM Global: Fired pressure vessels, boilers, boiler tanks

and their safety trains (controls that include combustion safeguards, safety shut-off valves, over temperature protection and pressure relief valves) are required to be FM Global approved.

2. Building Pressures: Design building to maintain positive

pressure, maintain environmental requirements (temperature and humidity) and ensure guest comfort.

? Minimum outside air intake quantities must exceed

building exhaust quantities by 10%.

? In high-rise buildings, consider \

and the resulting infiltration. The use of entry vestibules, with two sets of double doors will significantly reduce stack effect. See Module <2A> for application of architectural requirements at Lobby entrance.

3. Equipment Selection: Select and provide equipment,

components and specified materials rated for applicable service, environment, temperatures and pressures.

? Install interior designed equipment for inside use only

and not for outside use.

? Design and construct outside equipment for project

specific conditions.

4. Fire Protection / Life Safety: See Module <14>.

5. Environmental Requirements: Design and select

equipment to maintain indoor space temperature and humidity conditions when using ventilation requirements for occupants and internal heat gain in compliance with Table 15A-1 – HVAC Environmental Requirements at end of this document.

6. Dimensions, Sizes and Measurements: In this Standard,

conversions from English to metric (SI) units are approximate. Verify, coordinate and confirm product and material dimensions for required design applications.
