How you measure success it is extremely important. This can not be understated!
We believe what matters most to get domestic retrofit happening more often is;
1) Ave pence/kWh price reduction and Total £ saved on bills per home per £ spent
2) Ave gCO2/kWh emission reduction and Total kgs of CO2 mitigated per home per £ spent
3) Hybrid finance - Strategic public funds use to stimulate private capital into action - public £ invested : private £ invested
4) Private capital solidification - Priortising retrofit actions that convert well to property value - £ invested : £ property value change
5) Reduction in annual days counted where home is deemed uncomfortable or unhealthy (internal temp and humidity)
6) M2 of roof, wall and floor insulation installed - kWh energy demand reduction
7) Qualitative community benefits score :
8) Qualitative homeowner benefits score :
We have an inhouse system that (through APIs) draws down data daily in half hour increments for client electricity and gas usage, variable tariff cost, carbon intensity of grid, internal temp and humidity, etc. We use this tool to track our success metrics.
At our core, we believe in energy systems that are locally owned, cooperatively run, non-profit and rooted in social justice. CEB’s purpose is to replace the top-down, profit-driven energy model with one that puts people and communities first; building a cleaner, fairer, and more resilient Birmingham.
