Opening one room and opening two rooms may seem like the same action, but the electrical consumption differs. However, there is still a common perception that opening multiple rooms will double the power consumption. But, this concept is not entirely accurate. In fact, the actual usage depends on various factors, such as the type of appliances, their power consumption, and how they are used. For instance, if you open one room with a single LED light and a mini-refrigerator, and another room with two LED lights and a small air conditioner, the total power consumption may not necessarily double. It's essential to consider the specific electrical requirements of your house and the appliances you intend to use to get an accurate estimate of your power consumption.
