Green Zero Carbon Home
Renovation of 1970's house to a zero carbon footprint
General Energy Use, Strategies and Systems
Energy Use:
15kW roof mounted solar PV system
2 Bosch 5 ton ducted heat pumps
Triple-glazed windows
Extra insulation
Heat pump hot water tank
Zero Net Energy Definition Used
Site Energy Use
Monthly Energy Data and Utilities
Electric Utility: Eversource
Gas Utility: none
Other purchased Fuels: Heating oil
Datasets and utility bills sources and reliability: Annual heating oil data is 100% accurate for delivery records. Daily use is from gauges on the oil tank and is not as reliable. It is pretty good if averaged over about 5 days.
Electricity data is from Eversource bills and an Efergy whole house meter. It is 100% accurate.
Solar power data is from the Solar Edge reporting system and has been audited to the net-metering credits on my Eversource bills
