The problem is:• we have to address carbon reduction• increasing energy cost • with decreasing revenue
Current policy (BREEAM, Part L, SBEM) focussed on reduction in carbon but can cause increase
in operation costs
Typical College Carbon Emissions Base Line
New Campus Opened
Thermal Imaging
Solutions(No Cost)
• Check your contract
• Check your half hourly data
• Benchmark
• Check time and temperature settings regularly
• Behavioural change – not just about posters

Identify easy wins – lighting (LED), variable speed drives, boilers
Solutions(Cost)
Identify best low carbon or renewable energy options
Solutions(Cost)
Identify sources of finance
• Maintenance Budget
• Capital Budget
• Salix!!! (interest free loans)
• ESCo or SPV
(principally off balance sheet finance –
Green Investment Bank)
• Other – Bank Loans, Electricity Demand
Reduction, FITS, RHI
Case StudyStaffordshire University
Recommendations included:• low loss transformers and voltage optimisation• metering to the university buildings • insulate boiler house valves (campus wide)• targeted daylight and movement sensors to lighting• additional insulation to lofts• change T12 light fittings to high efficiency type• thermostatic controls to radiators• replacement of inefficient boilers• PC power management
• Savings achieved exceeded 12% over £400,00 of the
annual energy spend of £3m• Capital outlay £1m (Salix interest free loan )• Payback approximately 2.5 years
Conclusion
• Proactive management of estate performance
• Don’t rely on Part L or BREEAM alone as your solution!
• Have a carbon management plan and integrate into
estate strategy to maximise maintenance and capital
budgets
• Use SALIX!!!!
