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

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 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!!!!
