Sprint E|Solutions, 150,000 SF Web Hotel in Denver, Colorado
This is a co-location and web hosting hotel for Sprint’s entry into that
technology market. The building is a 150,000 SF facility with five 15,000 SF Customer
Equipment Rooms designed for 160 watts per square foot of UPS power delivered to the
Customer Room floor. The balance of space included 33,000 SF of Office and Support Space,
11,250 SF of UPS rooms, 8,440 SF of UPS battery rooms, 3,850 SF of POP rooms, 1,400 SF of
48 VDC batteries, and 32,000 SF of Support Area. The HVAC system is a mixture of chilled
water and DX systems. The total building load was 5,500 tons of which 550 tons are DX
systems and 4,940 tons of chilled water plant. A total of two 520 ton and eight 650 ton
chillers will ultimately be installed to meet n+1 including redundancy on the mechanical
system. A Plate and frame heat exchanger was installed under the first phase to provide
chilled water for the building utilizing free cooling from the cooling towers and the
system is laid out to incorporate 3 more heat exchangers for a total of 4080 ton of free
cooling. State of the art building automation system with redundancy is utilized for
complete monitoring and control of the facility. Monitoring is accomplished off site via
the internet, along with 100% backup of all programs.
Single preaction fire sprinkler systems and FM-200 systems are used in conjunction with
VESDA detection system to provide fire safety for the complex.
The building is fed by primary 15 kV power from the local Utility Company and will
initially have two Owner provided 4,687 kVA transformers to step the voltage down to 480
volt power. Ultimately, the building will have five 4,687 KVA transformers to serve the
total load. Initially, the building will have four 4,000 amps switchboards and ultimately
will have nine 4,000 amp switchboards. Standby power will have two 2,000 kW 15 kV
generators initially and will grow to ten 2,000 kW 15 kV generators ultimately. Power to
the Customer Rooms will be via UPS modules. Each Customer Room will have two 750kVA
modules paralleled together and designed for five 750 kVA modules. A total of five
systems will ultimately be used. The electrical system will provide 2N redundancy to the
Customer Room floor.
Quintiles Williams Communications, POP
sites, Kansas City, Missouri
One project included building out 12,000 square of backbone and co-locate area in
an existing building. The project included connecting an existing 15kV substation to the
exiting 15kV utility service and a new 1500 kVA transformer to serve the new 2000A 480V
system. A new 1,250 kW standby generator was located in the basement, adjacent to the new
15kV substation. A 3000A DC battery plant supported the backbone area. The mechanical
system included 10 computer room A/C units and two glycol dry-coolers for space
conditioning. A pre-action dry-pipe sprinkler system was expanded into the new area.
The second project included building out 25,000 square of backbone and co-locate area in
an existing building. The project included a setting a new 2500 kVA transformer to serve
the new 4000A 480V system. A new 2,000 kW standby generator was located outside adjacent
to the new transformer. Provisions were made for the additional of another 2500 kVA
transformer and 2000kW generator to support the 4000A Min-tie-main 480V-system. A 10,000A
DC battery plant supported the backbone area. The mechanical system included the initial
installation of sixteen 20-ton computer room A/C units and seven 50 glycol drycoolers for
space conditioning, with provisions for this same quantity to be added at a later date. A
pre-action dry-pipe sprinkler system was expanded into the new area.
AFN Communications, POP/Web Hosting Facilities in the Midwest
and Northeast United States
Multiple sites in the Northeast States of varying square footage ranging from
1250 SF to 15000 SF. Each site utilized computer room A/C equipment with DX condensing
units or dry coolers with separate pump enclosure. HVAC system utilized N+1 redundant
arrangement. Electrical systems were generally a 480V distribution to HVAC equipment, DC
rectifier and step-down transformers for lighting and small appliance loads, however, some
sites required medium voltage step-down transformers to achieve the 480V desired voltage.
A standby generator set was installed to completely back up each site in the event of a
power outage. DC battery plants varied in size and were based on 24 amps per rack with a
4-hour backup time. Design included layout of DC plant, ladder rack for DC power and
fiber/copper cable distribution and telecommunications grounding to achieve 3 ohms. Most
sites required a minimum of plumbing and fire protection generally utilized
double-interlocked pre-action sprinkler systems initiated by smoke detectors and/or manual
stations.
Blue Cross/Blue Shield Data Center, Kansas City, Missouri
Project has a total of 39,500 SF of which 20,000 SF is 24" high raised floor
area. HVAC system utilizes a central chilled water system with piping to units sitting on
the raised floor. The chilled water loop provides the chilled water storage for cooling of
main frames upon loss of power. Heat pumps are utilized to provide space conditioning in
the office and support areas. Entire building is sprinkled and a double interlocked
pre-action system is used in the raised floor area. Temperature controls use a DDC system
to control all HVAC equipment. A separate monitoring system is used to monitor HVAC
equipment in the computer room as well as power distribution units, UPS equipment and the
main service equipment. The electric service consists of dual primary (15 kV) feeders with
automatic throw-over equipment, a main-tie-main dual 480 volt switchgear with automatic
throw-over, and auto transfer switches to accommodate future standby generators. In
addition, the project includes two 500 kVA/400 kW parallel redundant UPS modules with 16
minutes of battery backup and three 415 Hz frequency converters paralleled to provide 415
Hz power to two 3090 mainframes. An emergency shutdown wiring scheme and signal reference
grounding grid was utilized inside the computer room.
