After the Energy Management course was completed, four students were tasked with reviewing the 20 group reports and combining all of the results into a single message for greater Tokyo. This was a big task that required combining many different approaches and assumptions, but they were able to find repeated patterns across many of the groups. For example, to improve the building stock most groups suggested rooftop PV, additional insulation, and heat pumps.
The slides present a wide array of results from the course, but the variability of methods mean that the results have a higher level of uncertainty than if the city was treated in a single project. For the 23 Ward area, it was found that 56% of the energy can come from renewables, energy supply can be reduced by 36%, and CO2 emissions reduced by 60% by 2040.
