1 Challenges of Building Highly Efficient and Available Data Centres in City Centres Vello Ehvert, P.Eng, LEED A.P President, Ehvert Engineering

2 Vs. Industry Challenges Possible Solutions

3 Overview 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.

4 Agenda 1. Why build data centres in city centres? 2. Industry challenges & possible solutions: 3. Hoisting i. Architectural ii. Electrical iii. Mechanical iv. Fuel Systems v. Fire Suppression vi. Other

5 1. Why Build Data Centres in City Centres? 1. Latency 2. Existing Infrastructure 3. Proximity to Staff

6 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

7 I. Architectural Challenges 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

8 Example A:

10 Issue II. Electrical Challenges Solution Generator Location Negotiate for roof space or locate in adjacent building

11 II. Electrical Challenges Issue Limited Incoming Capacity Issue Riser Capacity Issue Environmental Issues Solution Negotiate with Local PUC Solution Use stairwells, Elevator shafts, etc. Solution Perform Environmental Analysis

12 III. Mechanical Challenges Location for Cooling Towers, Chillers and Air Handlers Issue Heat Dissipation Look at Old Chillers that have been replaced Solution Consider Water vs. Air Side Economizers Consider Return to Return solutions

13 Before After

14 IV. Fuel System Challenges Issue: 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

15

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

17 Tools Lighting Modeling and Calculations using Visual Short Circuit Studies and Single Line Design

18 Computational Fluid Dynamic (CFD) Analysis

19 Computational Fluid Dynamic (CFD) Analysis

20 ICE: Computer Modeling

21 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
