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.
