Yes, it is possible to incorporate natural ventilation systems into the design of a zero energy house. Natural ventilation is an energy-efficient method of cooling and ventilating a building without relying on mechanical systems.
Here are a few ways to incorporate natural ventilation into the design:
1. Placement of windows: Design the house to have windows strategically placed to take advantage of prevailing winds and natural airflow patterns. This can allow for the movement of air throughout the house.
2. Cross-ventilation: Orient the house layout and design to promote cross-ventilation. This involves having windows on opposite walls to allow for the intake and exhaust of air. This flow can be enhanced by using design features such as internal courtyards, atriums, or roof vents.
3. Ventilation design: Incorporate features such as adjustable vents, louvers, or operable skylights to allow control over the flow and direction of air. These features can be designed to open and close based on temperature, wind direction, or occupant preferences.
4. Stack effect: Utilize the stack effect, where warm air rises and creates a pressure difference that draws in cooler air from lower openings. This effect can be enhanced by having high windows or vents near the ceiling and lower openings near the floor.
5. Natural cooling elements: Incorporate natural cooling elements such as shading devices, vegetation, or water features. These elements can help to reduce the temperature and improve airflow around the house.
By incorporating these natural ventilation strategies, you can reduce the need for mechanical cooling and ventilation systems, thus helping to create a zero energy house that relies on renewable energy sources for its energy needs.
