27. What we imagined
DX coil for seasonal
dehumidification – on/off
control
Small fan 100 – 150m3/h
1.2 air changes/day
(c.a. 30W)
Filter
Uninsulated duct
Uninsulated duct
29. Energy use – inc’ labs & offices
June 2014 – March 2016 - whole building
Gas 11kWh/(m2.a) c.a. £1,000/a
Electricity 34kWh/(m2.a) c.a. £11,000/a
PE ≈ 100 kWh/(m2.a)
Hopefully electricity use will decrease as building dries out and
lighting and other controls are sorted??
TFA:
Records Centre 1321m2
Repository 1130m2
Total 2451m2
33. Next time
• No BMS – save money and improve reliability
• Simpler dehumidification of air supply
• No frost coil (uninsulated ducts, turn fan off in extreme)
• Apply lessons learnt to the cooled photo-store
• Simpler heating – electric panel heaters?
