Overview
EHVERT engineering
High demand for data centers close
to the population
Increased requirement for Mission Critical Facilities in cities
This session will focus on:
1) Challenges faced with building data centers.
2) Possible solutions based on real life examples.

1. Why Build Data Centres in City Centres?
1. Latency
2. Existing Infrastructure
3. Proximity to Staff
EHVERT engineering
Differences – Greenfield vs. City Build Standard Data Centre Build• Greenfield or Single Story• Simple Structural Solution• Unlimited space for
electrical and mechanical systems
• No riser issues• Easy to hoist equipment• Easy to dissipate heat
Downtown Data Centre Build• Multi‐story – difficult access• Structure not rated for
industrial use• Limited space for electrical
and mechanical systems• Limited riser capacity• Difficult to hoist equipment• Insufficient space for heat
dissipation

I. Architectural Challenges
EHVERT engineering
• Commercial Buildings are not designed for industrial applications
• Working in spaces with multiple tenants• Transportation of equipment throughout building
• Security• Structural
• Commercial Buildings are not built to accommodate data centre structural loads
• Consider Steel and New Materials• Reconsider the weight of your equipment
• Access• Limited access to spaces based on available loading dock and
elevators• Work hour restriction

II. Electrical Challenges
EHVERT engineering
Issue
Generator Location
Negotiate for roof space or locate in adjacent building
Solution
Issue
Limited Incoming Capacity
Environmental Issues
Solution
Negotiate with Local PUC
Issue
Riser Capacity
Solution
Use stairwells, Elevator shafts,
etc.
Issue Solution
Perform Environmental Analysis
II. Electrical Challenges
EHVERT engineering
Look at Old Chillers that have
been replaced
Location for Cooling Towers, Chillers and
Air Handlers
Issue Solution
Consider Water vs. Air Side EconomizersConsider Return to Return solutions
Heat Dissipation
III. Mechanical Challenges

IV. Fuel System ChallengesIssue:
• Local Authorities – TSSA• Welded Riser• Tank Size• Fire Separation
Solution:
• Consider Variance Application
• Consider Containment• Look at new piping
alternatives• Size Day tank accordingly• Consider drywall, versus
block solutions

V. Fire Suppression
• Consider existing systems• Examine need for inert gas systems
• Consider recharging costs• Look at VESDA options• Consider challenges with traditional codes

3. Hoisting and Structural Challenges
Issue:• Commercial Buildings are
not built to accommodate data centre structural loads
• Restricting street access of high traffic areas for hoisting of equipment
Solution:• Consider new materials vs.
steel• Reconsider weight of your
equipment• Look at alternative hoisting
options
