Passive House Construction

Passive house
(Passivhaus)

What is a passive house?

  • A passive house is a very energy efficient building which requires such a small amount of heat that it can be heated mainly by “passive” sources such as the incoming sunlight and existing appliances.
  • Heat recovery via mechanical ventilation is necessary
  • The concept works well in any climate, from hot and humid to cold and dry; physics is the same everywhere.
  • Heating costs are reduced by approx. 90%

While there are many ways to achieve the passive house standard they share in common extraordinarily high thermal comfort and extraordinarily low energy consumption. Extremely low annual space heating/cooling demand is achieved through careful design; while there is wide discretion in design in terms, of how the targets are achieved the principles are consistent.

Elements of passive house design include:

  • Use of a design tool (typically PHPP)
  • Optional shape and orientation
  • Super insulated building envelope
  • Thermal bridge free design
  • Extremely energy efficient windows and doors
  • Air tightness
  • Efficient ventilation with heat recovery

Achieving passive house standard is design driven. In other words, it is straight forward to design a Passive House to suit any climate, location, lifestyle but it has to begin by design. It is very difficult and often impossible to make an existing design fit passive house standards.

Passive House and Net Zero

Net Zero, seeks to produce as much energy as is consumed with a “net zero” energy balance. Typically net zero requires energy production in the form of solar power, wind power or geo thermal power. Energy production is an expensive undertaking reliant on expensive and often complicated system with the added burden of maintenance and at some point replacement.

Passive house seeks to reduce and minimize energy requirements; through air sealing, increased, insulation orientation of windows and design elements. Other than above average windows and doors and air exchanger, the materials used in Passive House construction are standard materials, never require replacement and are relatively inexpensive yet the energy saving is considerable.

The point is that the least expensive path to net zero is through Passive House. Through the use of relatively inexpensive building materials the need for expensive energy generation is greatly reduced. If you use very little energy you need only generate a small amount to achieve net zero.
