Passive House is the world‘s leading standard in energy efficient design. It integrates the highest level of occupant comfort with the ultimate in energy efficient building construction. Despite the name, this design standard is equally applicable for all buildings of any shape, size, or use.

Passive House is built upon fundamental building science, thorough design, and high-quality construction materials and methodology to produce buildings that reduce energy consumption by up to 90% compared to conventional ‘code-built’ structures. The core premise of Passive House is that by reducing energy losses, and increasing ‘passive’ gains (i.e. solar heat gain), combines to reduce the amount of energy that needs to be ‘made up’ by a heating system (i.e. reduce the need for ‘active’ heating).

Although Passive House offers significant carbon reductions, the Passive House standard is fundamentally an economic principle, not an environmental initiative; the Passive House targets are derived based on economic principles to produce ultra-high-performance buildings with the most cost-effective solution.

The Passive House economic model looks beyond the simple ‘pay-back’ period. It considers initial capital investment (construction costs) together with ongoing operation costs over the life of the building. This is an ideal model for building owners/operators who should be concerned about long-term operating costs, since the result of Passive House is a building with operating costs that are consistent (regardless of season), independent of energy prices, and significantly less than conventional buildings.
