Where Does Indoor Air Pollution Come From?
Air pollution is often overlooked in home design, but if you're building or retrofitting a passive solar home, you cannot ignore it. Many traditional homes are leaky structures, allowing air to infiltrate through windows frames, doors, cracks in walls, and wherever else it can find a path. But passive solar homes rely on the house envelope being as airtight as possible. Obviously a 100% airtight home is a very bad, unhealthy idea, so ventilation must be provided – and ventilation can bring pollution with it.
