Consider how you worship - for churches
Share your building
Step 2: Reduce Energy Demand
Review heating and hot water timings
Zone your heating
Restrict the heating changes users can make
Protect your heating system from interference
Update your boiler controls
Check your thermostat and its location
Control your fan convectors
Fix a cold radiator
Check your frost arrangements
Turn down your boiler thermostat
Turn off hot water preheat
Reduce the hot water temperature
Change to point-of-use hot water on demand
Maintain your radiators and fan convectors
Disable the heating in summer
Put countdown timers on big electrics
Update your lighting
Force the lights offs
Reduce the size of heated spaces
Choose what spaces to use wisely
Use or stop solar gain
Step 3: Address Heat Loss
Make surfaces warmer
Insulate the roof
