1 Scope

1.1 This Standard defines the supplemental mandatory requirements of Heating,

Ventilation and Air Conditioning (HVAC) systems for Essential Operating

Facilities, in addition to the general requirements stated in SAES-K-001 for

Non-essential Operating Facilities.

Essential Operating Facilities shall mean electrical substations, process interface

buildings, satellite instrument houses, control buildings, analyzer shelters,

process management centers, switchgear buildings and any other buildings,

located onshore or offshore, housing electrical or electronic equipment and

control systems that are vital in the production, processing and transportation of

hydrocarbons, as defined in SAES-O-201.

1.2 Excluded from this Standard are process refrigeration equipment and systems.

Buildings used for Non-essential Operating Facilities, such as, office buildings,

maintenance facilities, dwellings, dining halls, recreation centers, etc., are also

excluded from this Standard.

2 Conflicts and Deviations

2.1 Any conflicts between this Standard and other applicable Saudi Aramco

Engineering Standards (SAESs), Materials System Specifications (SAMSSs),

Industry Standards, Codes, Forms and Saudi Aramco Standard Drawings

(SASDs) shall be resolved in writing by the Company or Buyer Representative

through the Manager, Consulting Services Department, Dhahran.

2.2 All requests to deviate from this standard shall be directed to the Company or

Buyer Representative, who shall follow internal company procedure SAEP-302

and forward such requests to the Manager, Consulting Services Department,

Dhahran.

3 References

All referenced specifications, standards, codes, forms, drawings and similar material

shall be of the latest issue (including all revisions, addenda and supplements) unless

stated otherwise.

4.3.4.3 Individual alarm devices shall be connected to a master

alarm in a location where they can be conveniently

observed by an attendant or other responsible person

designated by the management of this essential operating

facility.

4.3.4.4 In cases where the facility is not attended full time, the

system shall be connected to an alarm at the security office,

utilities office, fire station or other full-time service unit

with which arrangements can be made to alert the person in

charge of the alarm status of this facility.

5 Building Pressurization

5.1 Buildings Located in Hazardous (Class I, Zone 2 or Class I, Division 2) Areas

5.1.1 In buildings which are located in Class I, Zone 2 or Class I, Division 2

areas, the HVAC system shall be designed to prevent the entry of

flammable vapors or gases in accordance with the requirements of

NFPA 496, Chapter 5, “Pressurized Control Rooms.”

5.1.2 Air intake of the HVAC system in these buildings shall be located in

accordance with the requirements of SAES-B-014.

5.1.3 HVAC equipment, located in hazardous (Class I, Zone 2 or Class I,

Division 2) area, shall meet the requirements of SAES-P-100 and

SAES-J-902 for such locations.

5.2 Control Buildings

5.2.1 The HVAC system of all control buildings shall be designed in

accordance with the requirements of SAES-O-126; “Blast Resistant

Control Buildings.”

5.2.2 In these buildings the minimum outside air flow rate available for

building pressurization, as defined by paragraph 5.4.4 of this standard,

shall equal to 2.0 air changes per hour of the total pressurized space

5.2.3 These buildings shall be capable of maintaining an internal building

pressure of not less than 0.25 inch water gauge.
