Phased review at Chelmsford 4 phases:
Chapter House Cathedral and
Churchyard Cathedral Centre Residences
7 properties On-site and off-site
Review Process Review of bills Site survey
Energy Water Waste Transport
Survey findings
Review Process - Analysis Total electricity used 2005-2006
43,593 kWh/yr Measured floor area
Approx. 500 m2
Baseline demand and CO2 emissions 87 kWh/m2/yr, 36.7 kgCO2/m2/yr
Comparison with industry benchmarks Community centres 147 kWh/m2/yr Further education classrooms 181 kWh/m2/yr Social clubs 200 kWh/m2/yr
Step-by-step forecast for proposed measures
Review Process - Recommendations Low cost Investment Strategic long term
Low cost measures Simple monitoring and control strategy Energy-efficient and water-efficient equipment in
new kitchen Design-in facilities for recycling Complete change to energy efficient lighting Travel plan for staff and visitors Energy awareness programme Hypothecation of savings for investments
Example - Monitoring and Targeting Data collection
Electricity Water Waste Travel
Data analysis Reporting Action
Investment measures Central heating with radiators and gas boiler
Effective controls Effective insulation Hot water storage compatible with future solar system Designed to allow flexibility in future type of boiler
Regenerative braking for lift Internal insulation on walls Replacement water efficient appliances in toilets
Example – Internal Insulation100 mm glass fibre
40 mmpolystyrene
Cold Bridge
Strategic long term measures Electricity from zero carbon source Solar thermal system for hot water in summer
Possible CO2 emissions reduction

Modelling and Energy Profile
Summary Carbon and Security
Energy, water, waste, transport A strategic approach makes it feasible
