Mitsubishi Electric Designs Building to Reduce Energy Costs to Zero

It’s been a while since we talked about the Mitsubishi Electric Corporation, a subsidiary of Mitsubishi Motors Corp (MMC) that focuses on technology, energy, and is also behind a number of infrastructures in the everyday home. In fact, if the Dendo Drive House ever went global, everyone would be living in a house powered by technology similar to the latest net zero-energy building (ZEB) designed by Mitsubishi Electric. Called “SUSTIE®”, this ZEB is a testing facility building on previous clean energy endeavors by MMC. The latest results from this ZEB show that the building reduced its energy consumption to less than 0-percent. If the numbers are true, it actually created more energy than it consumed.

Now that is really, really cool. A medium-sized office building – 211888 cubic-feet (or 6000 cubic-meters) of floor space – is equipped with solar panels, and uses the latest ZEB operating technology to optimize operations. As we mentioned, this wouldn’t be the first time Mitsubishi Electric worked on net zero energy. In the past (2018) MMC partnered with ENGIE and Hitachi Europe Ltd during the first round of trying to create renewable energy.

Just like SUSTIE, ENGIE has their headquarters office building in La Défense, France, and is known as a Building Energy Management System (BEMS), outfitted with solar panels that collect and store energy for later use in the building’s power grid. Using a vehicle-to-everything V2X charger from Hitachi, any excess energy that the building couldn’t store was transmitted into a Mitsubishi Outlander PHEV, which could then operate as a portable battery. It worked out pretty well, and probably is the cause for the Dendo Drive House project in the first place. Mitsubishi Electric continued its experiments of net zero energy, and months later, via a new energy-management program, Mitsubishi Electric found that a company can reduce their electric power costs by 5-percent. It’s not a lot, but for a building spending $7000 every month, a savings of $500 per month is HUGE.

Now, let’s skip ahead a few years to now. SUSTIE is the new building that Mitsubishi Electric has been operating, and the new technology was able to bring about a 115-percent reduction in energy use. Like we said above, if a building can reduce energy by over 100-percent, in essence starting to go into the negatives, about -15-percent, then in short, it is, in fact, creating energy. Well, energy can neither be created nor destroyed, only misplaced to take another shape, but this isn’t a physics class. Let’s just leave it at this – the building was able to optimize its operations to the point that it generated and recycled enough energy that it has excess to burn. Just think of the possibilities this could mean for future operations, such as transportation and aerospace – the latter Mitsubishi has actually been a part of, such as the International Space Station (ISS).A short note, the operations by SUSTIE were managed by Mitsubishi Electric’s proprietary AI technology Maisart. That’s a name we haven’t heard in some time (2020). Starting as a virtual assistant and eventually implemented into vehicle navigation systems, operating an entire building is quite the leap. If this was a sci-fi novel, the tinfoil hats would be coming out right about now, but luckily, the skies are currently clear and this kind of technology can be put to good use, in the right hands.
