Carbon Based Energy Strategy
The outcome sought through this experiment is to optimize the correlation between renewable energy availability and the building’s energy demand, by:
- Using the grid’s energy at the moments when it is greener
- Producing renewable energy in situ
- Storing green energy to be able to use it when the grid is more CO2 charged
- Communicating with users in order to encourage them to plan their energy consumption at the hours of greatest availability of renewable energy, or of better quality of the grid’s energy.
Because renewable energy is not constant, a methodology is necessary to balance carbon footprint on a yearly basis with an hourly time accuracy. This strategy needs to be applied to the grid’s energy supply as well, for the CO2 content of the Swiss grid also varies significantly, due to its different sources and its dependence on imports from less performing grids at certain times of the day or of the year.
