Let’s get ready for a hot Japanese summer


With now one more nuclear power plant site in Japan in the process of shutting down their electricity production, I think one of the biggest upcoming challenge is how to cope with the typical high humid temperature during summer. Further METI is requesting cuts in electricity by 15 % for both households and companies. The scheme will be voluntary for household and small- and medium sized companies, while for big companies the reduction will be mandatory. METI indicates that a big company is a company that uses
more than 500 kW. As one consequence the air-conditioning systems will be set for sure everywhere at a higher temperature than in the past and although cool business is promoted, how can you make sure that you do not actually melt this summer? According to Nikkei Shimbun there are some tasks that will help to prepare for a hot summer. Although yesterday Tokyo was already experiencing high temperatures of 28 degrees Celsius it is still time to get ready. The recommended activities are:

– Make sure that you do some exercise outside in the morning or the evening that will bring up your heart beat and let you sweat a bit
– Focus on drinking warm drinks like tea
– Cut down on sweets

The goal is to train the body to get used to some light sweating. Now it is the time to get up and moving so that you can cope with the upcoming summer better. In case you know of any ideas or tips that help to make a hot, humid summer more bearable, do let us know.

  1. Good tips for personal conditioning. A nice breeze from propeller fans helps feel comfortable at higher temperature. each degree C higher reduces cooling load by about 10%

    Actually 15% in an office is achievable, even if you cannot replace the inefficient large air conditioner modules with modern inverter units. In household sizes these inverters typically consume half the energy for the same cooling effect compared to their 20-year-old predecessors without inverters. Same goes for the fridge. Payback within 7 years for the upgrade.

    More we can do: shut off unneeded units of the wall-to-wall overhead lighting, typically those above aisles or halfway above cabinets. On many offices these add little to workplace illumination. Every 100W saved reduces the load for air conditioning by an additional 50W, because less of the lamp heat needs to be pumped out. Even better, use 13W-27W personal desktop lamps and shut off overhead lighting.

    Shut off computer monitors when not at the desk. Ask IT to set the standby screen to “blank”, not to a screen saver, so the monitor can go to sleep and save some of what the energy star label promises.

    • Dear CoCreatr,

      thank you very much for your great ideas on how to safe energy.

      I think overall we go do with so much less energy in the office, so potentially this summer is a good way to cut back. On the other hand at home I still struggle where to cut further. Airconditioning is set at a high temperature and only used when we cannot stand it anymore. Otherwise whenever possible energy consuming actions are shifted now to be done during the night (baking, washing, ironing) and the rest is cut to a minimum.

      Let’s see how much we can actually cut our energy consumption this summer,

  2. Hopefully I’m ready… as much as a workout I should be, but it was humid yesterday and the humidity was high as 75% in the house. I didn’t know that about warm tea though? I drink it cool, esp after a workout or water with some lemon… hmm I wonder if Chubu will take the advisement, I’m eager to know.

    • Dear Elle Marie,

      it seems we have an opposite situation: I drink lots of warm tea, but doing badly with workout :O Humidity is truly a challenge, especially with higher temperatures.

      Now with the potential shutdown of Chubu this summer will become even more interesting. Based on the news from Asahi Shimbun the region depending on the TEPCO will face even a tighter electricity supply, because Chubu Electric’s supply capacity toward TEPCO is 1.03 gigawatts.

      I guess, there is no choice but hot tea for you and for me some workout ;P

      All the best,

      Sibylle
