Usage<br />
17/9/18 to 21/9/19: 26340kVA<br />
14/9/16 to 17/9/18: 42900kVA ~ 21<strong>450</strong>kVA/yr<br />
That is fused at 80A/phase and is not looped.<br />
To know how much “headroom” there is does depend hugely on the usage pattern of the Vodafone supply. Considering<br />
it “constant” 24/7/365 would mean 4kVA, so a headroom of 69-4-32=33kVA. Applying the Vodafone annual usage against<br />
a standard commercial usage profile infers a maximum demand of 33kVA so a headroom of 69-33-32=4kVA.<br />
Figure 2 - Existing gas infrastructure.<br />
The required services capacities are as indicated in the design criteria second of this report. The conclusion is that the<br />
new development requires significantly more energy than can be provided from the existing supplies.<br />
Water<br />
An existing water main serves the site from <strong>Redcliffe</strong> Way.<br />
Telecommunication infrastructure<br />
The existing telecommunication connection into the building will be extended to serve the new areas.<br />
Gas<br />
The location of local gas infrastructure has been investigated to determine the impact it will have on building works. As<br />
of the enquiries performed in November 2019, there is a gas main running within the road adjacent to the development,<br />
with a gas main running across the front of the church to serve the existing boiler and kitchens.
