Passive House buildings are designed to be comfortable all year round – cozy and warm in winter (20°C), comfortably cool in summer (25°C).

In some homes, passive heating alone will maintain stable temperatures year-round without any need for supplementary heating. Others may need additional heating in winter – this supplementary heating will be far more effective in a home that uses passive heating principles.

Of course many passive house owners do put in central heating as a back-up — but some don’t. In 2005, Scandinavian Homes built one of their passive timber frame houses in Brittas Bay, Co Wicklow for Eddie Brennan and his wife Fran, who installed 16m2 of solar thermal panels and some underfloor heating pipes.

Passive structures make use of shade, sunlight, and other internal and external temperature sources to eliminate the need for an active heating or cooling system. While there’s no one-size-fits-all approach to building a passive house, our infographic shares how these structures work, so you can better plan the design of your next home .

Do passive houses need heating? They do, but much less heating than a standard house in the same climate. If a house is airtight and well-insulated, the indoor environment will remain warmer (or cooler) longer—much like a good thermos that maintains the temperature of whatever you put in it.

A passive house creates a comfortable and consistent interior climate without an active heating or cooling system. It achieves this by combining key features such as high-quality insulation and ventilation. In a standard building, heat is usually lost through small openings like cracks, inefficient windows, or overall poor insulation.

A common misconception with Passive Houses’s is that they can heat themselves, whereas in truth they are carefully designed to ensure maximum retention of any generated heat – but the heat still has to come from somewhere. A Passive House has a space heating energy demand of <15kWh per square metre of living space per year.

The heat loads in a Passive House are very low. The heat flow between rooms in a building is the same as less well insulated houses. We do not need to heat all rooms, so can use a simpler heating system. Buffering through the mass of a radiator system or floor heating enables a standard size heat source to be matched to the much lower heat load ...

Passive heating and cooling in homes is simply a matter of determining where the sun exposure is, and trying to capture and keep as much of that heat as you can in the winter while keeping it out in the summer. This may seem like a tall order, but the seasonal position of the sun conveniently serves this end.
