- derefr 6y agoThat's nice for heat, but thermal mass means that air conditioning is most efficient when it can get the whole room to equilibrium and then shut off. Like a car coasting going down a hill.
- carlmr 6y agoI always see it like this, if it's cold you can put on more clothes (you probably already have them, and they don't waste energy to wear). When it's hot, there's a certain societal lower threshold for what you're allowed to wear in an office (depending on the office shorts are ok, but not less). So you can't individually cool down.
- sepin4 6y agoI just bought my apartment last year and I made the decision to use infrared panels for heating. Best decision ever. No moving parts(no noise and no constant breeze), no dry air indoors, the heat is actually stored in the walls and furniture(denser objects), so I can vent the air regularly without loosing much energy. And it's supposed to help generate vitamin D which during the winter is usually a problem. The downside is that it takes longer than air conditioning to warm up the same room and it requires great wall and floor insulation(which I have). There is also the problem of overshooting the temperature(because the panels don't cool immediately, it takes about 15-20 min), which is solved in some thermostats using hysteresis algorithms for the temperature delta(it uses shorter cycles between on and off and more precise measurements, however this could wear the electrical panels quicker). I'm not that sensitive to the temperature so I don't use those and I have my temperature sensitivity up to 0.5C.

- sepin4 6y agoYes, you are correct. I've misremembered the effects. However there are other positive effects from infrared light.In any case, this is just a bonus to the actual purpose of the panels.
- graeme 6y agoWhat did you buy exactly? This sounds interesting but I have never heard of this.
- sepin4 6y agoThere are many different manufactures and models. Mine are constructed in Austria. Here are some examples: https://www.redwell.com/en/products/ https://www.redwell.com/en/products/ https://www.sundirect-heater.com/frameless-infrared-panel-heater/ https://www.sundirect-heater.com/frameless-infrared-panel-he... https://www.heat4all.com/en/products https://www.heat4all.com/en/products The cool thing is you can make it part of the interior. I have 3 panels hanging from the ceiling, 1 painting and one mirror. They can be integrated into hanging or floating ceilings and usually have standard dimensions. You have to be aware, that most panels do not have thermostat. They have only one operating mode - On. In order to regulate them, you have to put a thermostat on the electrical line before it(essentially a smart switch). There are thermostats for wall integration. I use those, the cables are hidden in the wall and the actual thermostat is mobile so it can measure temperature at any location in the room. There are also thermostats which are plugged directly on electrical sockets for more integration out of the box. The price is comparable to any other heating solution and the consumption is a little less than air conditioner. Mine came with 5 year warranty. I just hope that they last longer, but with the exception of the painting, all the rest are easily replaceable.

- dghughes 6y agoThe mantra I've heard is "move heat (energy) don't make it". Don't burn or even use renewable enery to generate heat but move heat already present. Move it away to cool and move it towards somewhere that needs heat.
- omegabravo 6y agoMany* places normally don't have the same temperature since people do wear jumpers in winter and less clothes in summer. Buildings are often (not always) set to 24-25C in summer, and 21-22C in winter. *no figures sorry, just in my experience
- throwawayboise 6y agoAt my office the climate control is considered adequate if it is 68 or above in winter, and 78 or cooler in summer.
- mattowen_uk 6y ago20 Celsius / 25 Celsius.
- elzbardico 6y agoI find anything over 22C too much for intelectual work. So, I am glad I WFH
- devdas 6y agoHeh, I find it uncomfortable under 25C.
- stoolpigeon 6y agoMy wife and I live in Hungary. Every so often we visit Phoenix, AZ in the summer to see family. (My wife is a teacher so it makes sense to go in summer) and the hardest thing for us to do when we go out to eat is finding a restaurant that has seating where we are not freezing cold. It will be 40+ outside and 20 inside.
- bobthechef 6y agoYeah, regrettably, the American practice seems to be to overchill in the summer and overheat in the winter. This is also done in the home to the point that people will wear shorts and tshirt indoors in the winter and warmer in the summer (blankets while watching TV for example). Also office buildings suffer from the same problem. Women usually complain the most about it being too cold (men are more likely to wear suits and generate more great I believe).
- andrewingram 6y agoWell, jumpers and thick gloves. Due to circulatory issues my hands often turn numb and blue in offices where the AC is cranked up, even if the rest of me is toasty warm.
- dghughes 6y agoMaybe you should drink tea. It would warm you up and supposedly tea has mild blood "thinning" properties. You're not supposed to drink tea if you're going to have surgery. For air conditioning the best part of it is the dehumidifiation. It doesn't need to be arctic cold just the dryer air and a bit of cool is OK.
- dhekir 6y agoOP could be referring to Raynaud syndrome (https://en.wikipedia.org/wiki/Raynaud_syndrome https://en.wikipedia.org/wiki/Raynaud_syndrome). It's not sure tea helps in such cases.
- sekh60 6y agoThanks for the link! I had not heard of the syndrome before. but it could be what my wife has been suffering from for the past year or two. We already are waiting to see a specialist to have a look at her, so I won't make any conclusions, but that seems very likely it.
- dghughes 6y agoI have Raynaud's disease and cold weather alone isn't a trigger for me unless I am not wearing gloves and if I am holding onto something. A shovel when shovelling snow, or pulling a heavy cart. It has to be a continuous session not just one thing for a few minutes. I've also been sitting quietly at home and suddenly half my thumb goes purple and the other half is fine. You know it's Raynaud's syndrome because it feels like someone hit your hand with a hammer. It's not just cold hands it's the pain too.
- datameta 6y agoAs much as I am a huge fan of tea, in this case I think the vasoconstrictive property of caffeine would have the opposite of a therepeutic effect.
- distances 6y agoAlways the same AC fight at the offices, one of the things I don't miss with this work-from-home. My preferred room temperature would be 27C which is obviously a no-go in a shared office, but cooling to 20C in summer is just as crazy too.
