What characteristics does a passive house have?
A passive house must meet certain requirements and characteristics:
An adequate orientation. It’s important that these houses are located in the appropriate place to be able to benefit from the most sun radiation possible. If we build these houses in places where they are in constant shade, you can start forgetting about producing solar energy!
An intelligent design. As with the orientation, a strategic design, as could be one of large widows, will permit the entry of natural light. Just what you need!
Isolation of floors, walls and ceilings. There is no point in generating energy if you are not going to know how to maintain it. For this system to work the house must be perfectly isolated and the way to obtain this is using the appropriate materials. Don’t let any energy escape!
Good doors and windows. Doors and windows are the weak spot of passive houses. Warm air can easily escape through them and that is why you must make sure they are of the best quality.
A ventilation system. As you can’t open doors and windows to renew the air, you will need a system of ventilation to carry out this function. It must be a system that controls the airflow so that if it’s cold, it uses the air you have generated and if it’s hot, it integrates cold air.
An airtight environment. This means that in the house there must be no air currents. They will affect temperature and with it your energy savings.
Elimination of thermal bridges. Thermal bridges are those areas in your house where warm air is easily transmitted to other rooms. These areas are usually joints and axes where different materials coincide. The solution is to add another thermal isolating material.
