In addition to upgrading the supply units with control and filtration upgrades, we implemented:
Retrofit Variable Air Volume (VAV) to the existing fume cupboards.
Install pressure controllers to each laboratory.
Initiate fume cupboard diversity into each laboratory.
Remove individual booster fans and upgrade secondary fans with VSD’s.
Installation of energy monitoring units to verify savings and act as MM&T capability.
A monthly (usage) figure of around 120 mWh has reduced to around 70 mWh, which is a very significant reduction. When we also compared total use for the whole Wilton Centre, we see reductions of 9.5%. It is our intention to now carry out similar modifications in D, N, & E Blocks.
