“initial assessment > carbon reduction measures > onsite renewables/energy networks > offsite renewables”
These are the steps we like to follow when considering rooftop solar.
First conduct a building assessment. What is the embodied and operational carbon impact of the building? Ask your energy supplier for you half hourly energy usage for the most recent rolling year. Secondly consider what can be done to reduce the emissions and energy use. Implement reduction measures such as LED lighting, double glazing and insulation where possible. Thirdly bring in on site or near site renewables over grid renewables. Renewables energy generated somewhere else suffers from energy losses when being transported. So keep green energy generation as close to home as possible. Finally, fulfill all other energy needs with a 100% green energy tariff from your energy supplier.
