expect that should a DES become established, it would continue to grow connecting additional
multi-storey buildings along Airport Road.

The feasibility of connecting prospects east of Mimico Creek, Figure 2 #’s 12 through 23 would
require a special investigation of the issue of using the bridge(s) as pipe supports. This might
be feasible as an eventual system expansion provided Phase 1 was established.
The possibility of serving additional buildings on airport property, i.e. south of Airport Road, not
already served by the proposed system could be investigated later if a core DES became
established.
2.2 Load Diversification Factor
A DES will normally have a lower thermal peak than the sum of the individual buildings’ thermal
peaks. This is due to the fact that individual buildings reach their respective thermal peaks at
different times during the day. This is known as load diversification. The mix of different
