Picture: CIS Tower, Manchester

The CIS Tower in Manchester is the UK's largest solar PV project which cost £5.5m to implement, and received over £1m in grants, the tower generates in excess of 180 000 kwh annually reducing CO2 emissions by 90 000kg. The scheme on the 40 year old building also offset the need to reclad the existing building with traditional rainscreening, which would have an adverse ecological impact.
