HAIG HAUS

HAIG HAUS is a new modern affordable passivhaus duplex added on top of an existing duplex, employing a unique strategy to provide increased density on a small site without demolishing existing housing stock.  Designed to minimize disruption to the existing building, the new building straddles the existing building and is structurally independent.  An extremely compact form combined with a super insulated envelope and high performance windows allows Haig Haus to meet the Passivhaus standard requirements for minimal additional costs.  Motorized external blinds provide solar shading for the large south and west windows.  In addition to the fabric first approach, a 17kW roof-mounted PV array will make the 4-unit building net positive; generating far more energy than it consumes.

A screened stair provides access to a new second floor open porch with the entrances to the new units.  The living level is placed at the top of the building to maximize views and solar access.  A small penthouse provides access to a south facing roof deck and garden.  Concrete columns and shearwalls ground the building, while the walls will be clad in a charred wood siding with white accents.
