Original title: What about passive houses that can be heated without floor heating and air conditioning?
Does your house have heating equipment? It could be a heater, a radiator, a central air conditioner, or a floor heater. But these heating devices are often accompanied by high energy consumption. Are there more energy-efficient heating methods?
In 1991, Dr. Fest of Austria built the world's first passive house.
Let's see what he has done.
1. Good building insulation performance. Just like putting on a white winter shirt jacket, we also apply the same principle to the passive room.
2. Excellent building air tightness. Reduce indoor heat emission to the outdoors, no matter how much.
3. No hot and cold bridges. Hot and cold bridges are like a channel to heat. The heat is thus radiated directly through the wall. In fact, most houses have hot and cold bridges, and indoor heat can be easily radiated to the outside through the hot and cold bridges.
Add all these measures together, and your house no longer needs heating or air conditioning. So, where does the heat from the house heating come from?
Passive houses reduce energy consumption by 90%. The heat emitted by your body meets part of the heating needs. Sunlight, appliances, lighting and even televisions can provide the heat needed for heating.
Of course, at this stage, there is no way to fully popularize passive houses, but we can still do a good job of thermal insulation of houses to save energy.
1. Select energy-saving door and window system with better sealing and better heat insulation effect.
2. Use suitable interior wall insulation, although it will take up a few centimeters of indoor space, the insulation effect is excellent.
In short, compared to the differences in heating equipment, the insulation of the building itself is more important for energy saving. Do a good job of building insulation, reduce the need for building heating, and jointly protect our natural environment!
