TRCA Pearson Eco-Business Zone District Energy Feasibility Study 10 April 2012 Figure 1 Estimated Natural Gas Consumption by Address Figure 1 shows there are buildings with significant heat loads all around and inside the Airport, but the area of most interest, which is highlighted by this illustration, is the area immediately north of the Airport, but south of the railway tracks and west of Highway 27. This area is mostly in Mississauga but includes a significant slice in Toronto (between Highways 27 and 427). This area appears to contain a large number of buildings with significant heating loads and is close to three Cogeneration Plants, which are owned by (1) Magellan Aerospace, (2) Trans-Alta (identified in Figure 1 as the Mississauga Cogeneration Plant) and (3) the Greater Toronto Airport Authority (GTAA). Therefore, it was decided to focus the investigation of building loads on this area, i.e. postal codes L4V (in Peel Region, to the west of Highway 427) and M9W (in Toronto, to the east of Highway 427). 9
TRCA Pearson Eco-Business Zone District Energy Feasibility Study 10 April 2012 2.1.2 Prospect Screening Various attempts were made to screen the large number of businesses in the Pearson Eco- Business Zone by using a combination of the previous Project Green work with various aggregations of actual consumption data that Enbridge could provide while not violating customer confidentiality. The data thereby assembled based on postal codes confirmed a level of natural gas consumption in the quadrant of interest (i.e. postal codes L4V and M9W) of sufficient magnitude to warrant investigation as to whether a material portion could be offset with district heating. Throughout the Pearson Eco-Business Zone, there are numerous large single-storey light industrial buildings. This type of building is usually heated with air directly from distributed roofmounted heaters. These would be expensive to connect and retrofit with hot water and have relatively low avoidable maintenance and capital replacement costs and therefore relatively low district energy service price potential. Also, it is doubtful whether their owners would attribute high utility to the value added features of district heating (comfort, convenience, reliability, longterm price stability and environmental sustainability), as might owners of multi-residential, institutional or Class A office buildings, which are the natural markets for district heating. FVB was most interested in finding clusters of multi-storey buildings or, at least, industrial facilities of a type that could conceivably include process loads. The most effective way found to do that was a combination of field inspection with use of Google Earth. This allowed the footprints and number of storey to be estimated. The uses of buildings of interest were determined from visual inspection. They turned out to be mainly hotels, offices or industrial. No pure residential buildings were found (as is appropriate near an airport), but one institutional, residential complex, the Toronto West Detention Centre, is on the periphery of the study area. The field visits to the area confirmed the existence of numerous, multi-storey buildings along or close to Airport Road/Dixon Road 4 ; but the area further back from Airport Road/Dixon Road, further northeast, contains almost no buildings of more than one or two storey. The area (away from Airport Road/Dixon Road) is almost uniformly light industrial with some attached offices, but the offices are relatively small and at most two storey. The Cara Kitchens, Booth Centennial Laundry, Cott Beverages, BASF and the City of Toronto Disco Road Transfer Station were the only industrial facilities that appeared to be a type that might have process heat loads. As a result of this field investigation, 36 prospects were selected, as listed in Table 1. The locations of the 36 selected prospects are shown in Figure 2. # Name # Name 1 Hilton Garden Inn 19 BASF 4 The name of Airport Road changes to Dixon Road as it crosses under the 427 going east from Peel Region into Toronto. 10
