Site Energy Manager Comments:
We have just read the electricity meters in R Block for April, & I thought you might be interested to see the effect of the ventilation modifications which we have carried out. Basically, you can see that a monthly figure of around 120 MWhr has reduced to around 70 MWhr, which is a very significant reduction.
When we also compare total steam use for the whole Wilton Centre for 2009 with 2008, where we see a reduction of 9.5%, & some of this will be due to the similar work we did in T Block.
It is our intention to now carry out similar modifications in D, N & E Blocks.
