Read a full report of the refurbishments of TEIGN VALLEY COMMUNITY HALL, EX6 7WA      

Energy/carbon saving works completed 2021 – 2025:

• Cavity wall insulation (resin beads) to supplement 50mm cellotex on inner surface of cavity
• Replace original double glazed doors with thermally efficient doors in entrance and main hall
• Automatic door in entrance to deter propping open
• Additional loft insulation throughout, to total depth of ~600mm
• DHW: Replace x2 300L hot water tanks with x3 30L point of use electric water heaters on max 4 hour time
• Replace x2 oil fired boilers with x3 ASHPs (2x 14kW for main hall, 1 x 14kW + 300L buffer vessel elsewhere
• Radiators fitted with tamper-proof TADO smart thermostats, remote control via app
• Main hall heating timer-controlled via remote app, with ‘setback’ temperature of 16C
• Lights replaced with low energy LEDs, many on motion sensors and timers       
• Solar PV and battery installed

These works help to reduce energy use and carbon by:

• Improving the fabric of the building (insulation, controlling airflow and airtightness) to reduce heat loss
• Replacing heat generators with much more efficient (and effective) appliances that use less fossil-fuel
• Reducing or removing sources of wastage (un-used DHW, frost prevention heater in loft)                          
• Minimising energy wastage caused by hall users forgetting to turn things off (behavioural changes)     
• Installing on-site electricity generation to cover some of our energy needs (~30%)                                        

Impact for hall and hall users:                                                      

• User comfort – heating that actually works (and new aircon gives potential for a cool space for the future)
• User convenience – a self-service facility so important that controls are automated or simple                   
• Hall volunteers’ convenience – control heating from home                                                       
• Hire costs are kept down (energy bills are at a historic low in real terms)                                                           
• Hall remains viable as a community facility for the foreseeable future                                                

Next steps:                                                           

• Replace remaining double glazing with better units
• Continue to monitor system performance and user behaviours to identify further energy saving actions
