SANTA FE CDMX
[MEPF]
Takasago Engineering México

3
Actual
Condition:
BMS system will be independent from the
Santa Fe Plaza.
No current information from Santa Fe
commercial plaza.
Recommendations:
The BMS system will be monitored
independently for the store.
MEPF – REVIEW
System Reviewed: BMS System

4
Actual
Condition:
Currently the Santa Fe has 7
AHU units.
Other areas have minor
equipment such as minisplit
units, not recommended for
reusage.
Equipment brand is TRANE, 9
years of usage.
Key
Findings:
Limited space on roof for extra
equipment.
No heating is incorporated in
the existing equipment.
Skating ring that is in BL causes
low temperature in the
surrounding areas.
Temperature observed in the
food court (currently not in
usage) is of 12°C.
Recommendations:
Implement heating stage for
additional air conditioning units.
Structural loads for additional
AHU shall be analyzed.

USING ONLY EXISTING EQUIPMENT
Remark:
• Not recommended; it is not in compliance
with IKEA ECM Chapter 5 section 5.1.3,
because the differential temperature of the
supply air is below dew point temperature;
therefore, condensing is to be expected on
diffusers.
• The differential temperature between room
air temperature and supply air cannot
exceed 10°C.

Actual
Condition:
Currently the Santa Fe has no
provision connection for smoke
extraction.
Key
Findings:
Front perimeter is not to be
used for extraction.
Recommendations:
Mechanical extraction shall be
implemented for this case.
• Smoke hatches are not to be
considered for this project
due to the opening on roof
and available space.

• IKEA ENGINEERING & CONSTRUCTION MANUAL
• CHAPTER 7 7.6.2.2
• The air velocity for make-up air in evacuation routes may not exceed 2m/s.
• Maximum commercial smoke extraction is 39,300 CMH (from Show Room /
Market Hall).
• When air velocity is less than 2m/s, effective opening size is as below.
• 39,300[CMH] / 3,600[s/h] / 2[m/s] = 5.46 m2
• When make-up air from louver, louver size is 13.65 m2 (opening rate 40%)

Actual
Condition:
The main existing equipment
from Sears:
• One 500 KVA transformer.
• One 750 KVA transformer.
• One 250 KW generator.
Key
Findings:
BL1 substation space & Roof.
Recommendations:
Currently under IKEA standards,
one transformer with enough
capacity to hold all loads should
be installed, as well as a standby
equipment with the same
capacity (Ikea’s Engineering and
Construction Manuals, Chapter
8, Section 8.1.2).
• In order to join both
transformers, they are
recommended to have same
capacities and supplier must
guarantee alignment in
impedance.
• In case of reusing
equipment, loads will be
segregated.

Goods Classification / Hazard Classification
The basis for the Product Classification Report, Code
Consultants, Inc., 2009 report is on account of the inventory
and classified material as per NFPA 13. Keeping in mind that
this is a benchmark report between two stores in the US,
from 2009 and with different sizes compared to Santa Fe
CDMX.
Therefore, if a new Goods Classification is to be made, in
order to change the Hazard Classification, reevaluating the
inventory is a must.
