Japan Seeks Power To Turn Down Private Home Air Conditioners Remotely, Report Says (japantoday.com) 146

Posted by BeauHD from the remote-control dept.
Japan Today reports: As reported by Japan's Nihon Keizai Shimbun, in a meeting on Nov 2, the Energy Conservation Subcommittee of the Ministry of Economy, Trade and Industry resolved to begin working group discussions with the aim of gaining the ability to remotely turn down privately owned air conditioner/heater units. The goal would be to decrease energy usage during expected power shortages, which the committee feels are a growing concern as Japan attempts to shift towards renewable energy sources such as solar power, where the amount generated can be affected by day-to-day climate, making it difficult to stabilize the amount of total power available. The ministry says that AC unit usage accounts for roughly 30 percent of household electricity consumption in Japan.

From a technical standpoint, the plan wouldn't be particularly difficult to implement. Japanese air conditioner units have long had remote controls, so external inputs aren't a problem, and many models now allow the owner to turn the system on and off or adjust temperature settings through the internet. By asking manufacturers to extend such access to government regulatory organizations, and granting those organizations override functions over other inputs, the plan could easily be put into practice for internet-connected AC units, and water heaters are another home appliance the committee is looking to gain the ability to throttle back. [...] According to Nihon Keizai Shimbun, the committee is currently working under the concept that the government would only be able to turn down AC units if their individual owners have agreed, in advance, to grant that authority.

      The ideal situation here is that HVAC systems would have a standard thermostat, which in Japan, many heating systems are not central unless they're large office buildings. They're usually a less efficient unit in a single room of the building, because many Japanese homes are uninsulated. The same reason the Kotatsu is a standard piece of furniture. They heat just the space under the living room table.

                Opt-in/out is all well and good, but irrelevant to my point. Being able to send out a signal to the AC units is exactly remote access. It's irrelevant whether people think it is or not. There are risks involved, either way it's done, but allowing an external source access is generally less preferable.

    This is one of the slippery slopes of government control. First they only have power over those who agree. Then the corporations owned by the same people also who control the politicians coerce compliance among some. Then the media steps in and pushes it hard. Then a judge gets to say that it's obviously in the interest of the public for it to be enforced in some edge cases. And on it progresses. When a certain percentage of people are compliant it changes from those who freely agree to those who were agreed to everyone. And make no mistake, this is not "the government" who has the power. It's the people who own the government.

    The biggest problem is that many homes in Japan are still uninsulated due to the sweltering heat that the region experiences during the spring and summer. Ventilation is prioritized over insulation. But now with so many homes utilizing mini split systems to offer both heating and cooling, insulating homes would help a lot to reduce power usage as well as investments into other technologies like cooking with induction cooktops.

This is true of any warm climate where civilisation formed prior to the invention of the AC. What you do "new" is irrelevant. The worst offenders are those who don't offer retrospective solutions.

You can't even choose insulation as an option if you're building a home there. They just "don't do it". They could easily save massive amounts of energy by retrofitting their houses and apartments.

    The big problem with this remote override is people make the decision months before, so when it actually happens the decision no longer feels like their own so people get predictably pissed off.

    So the solution is to make sure the people still feel like they have control by moving the decision point to the time when you need the power.

    So instead of just making it a remote override you make it an auction. The thermostat starts dinging and people get a prompt "power usage is too high, so for X yen / hour can we set your thermostat to Y degrees?"

    Now people are happy to change the temperature because the decision, discomfort, and reward are all happening at the same time.
