Passive House | Modular Buildings

the power of a GREAT idea

Passive House is a German building certification system that reduces energy consumption and greenhouse gas emissions by up to 80%.

One way Passive House buildings achieve their energy efficiency is through the design and construction of highly insulated building envelopes which minimize heat loss or gain and help maintain a constant temperature.

The basic Passive House concept can be simply explained by comparing a coffee machine with a thermos. The machine requires constant energy to heat and keep coffee warm while a thermos just uses the beverage’s initial heat to keep it hot. In a Passive House building, warmth from indoor lighting, appliances and people occupying the space can actually provide most of the heat needed.

ELEMENTS OF PASSIVE

Achieving Passive House certification involves specialized building techniques designed to drastically reduce the energy required to heat (and cool) the building in order to maintain a comfortable temperature.

Simple Shape

Heat loss is minimized by calculating the building’s most energy-efficient footprint.

Superinsulation

Appropriate insulation levels are incorporated depending on climate zone.

Windows

Argon gas-filled, triple glazed with two low-e coatings, set in insulated frames and spacers.

Airtight

Special lining treatment prevents air infiltration and protects against moisture damage.

Thermal Bridge-free Construction

Prevents heat transfer in key sections of the building.

Supply Air Heating

Ventilation uses a ground air heat exchanger for circulating fresh air and heating recovered air.
