Energy-intensive building

This construction project consists on two phases of two detached wooden houses, the parcel with a total area of 638 m² forms two private gardens. SABA performs two individual terraced houses on parcels of 300 m2 each. The land is flat. The site is in a rural landscape, hedgerows are bordering the field on Southwest and East.

The surrounding field remain unchanged, only the access of the site will be relocated to fluidify the traffic. 

The program consists of two identical houses (four-rooms houses) with very good energy performance (Passivhaus).

Each house is composed of three separate volumes, the residential part is treated in traditional two sides slate roof and zinc deck roof in the same tonality for the saddler.

The main volumes, oriented east-west, shelters the living areas on two levels. The second volumes, more modest, are perpendicular to the first and shelter a room downstairs. The lowest volume is the cellar and its roof terrace create an awning which marks and protects the house entrance. 


Sustainable development approach of the project owner

Environmental criteria were paramount in this project while ensuring visual, acoustic and olfactory comfort of the structure.

Architectural description

The program consists of two identical houses (four-rooms houses) with very good energy performance (Passivhaus).
Each house is composed of three separate volumes, the residential part is treated in traditional two sides slate roof and zinc deck roof in the same tonality for the saddler.
The main volumes, oriented east-west, shelters the living areas on two levels. The second volumes, more modest, are perpendicular to the first and shelter a room downstairs. The lowest volume is the cellar and its roof terrace create an awning which marks and protects the house entrance.
These two constructions are designed and constructed on a passive level. They respect the RT 2005 BBC Passivhaus standard with traditional construction techniques by increasing the insulation thickness. The energy consumption of heating, domestic hot water by thermodynamics balloon, dual-flow ventilation, auxiliary and home lighting is 31.0 kw hep/m2 (less than 42kwhep/m2 of Passivhaus label) and 6.35 kwh EF/m2 year (well less than 15 kwh EF/m2 year max of Passivhaus label).

    Noble wood, the Red Cedar is a naturally durable without sapwood which takes a beautiful silvery gray color with age. Imported from Canada

    This material is appreciated for its natural beauty and durability. Indeed, the red cedar is richly textured. The colors range from pale amber to ochre brown. It allows multiple domestic uses. Free of pitch and resins, it accepts all finishings (oils, dyes, coatings, paints). Thanks to its preservation oils, the cedar naturally resists to the moisture, rot and insects. It is also naturally anti-microbial and fungicidal. It has acoustic properties that prevent the transfer of sound vibrations and is soundproof.

Construction and exploitation costs

  • 245 000

GHG emissions

  • 1,80 KgCO2/m2/an

Life Cycle Analysis

    The houses are made entirely of wooden frame. They are over-insulated, which has the effect of avoiding the use of triple glazing. Wooden cladding is left natural for the two main volumes. A rendered masonry is used for cellars and for limits constructions, a rainwater recovery system equip them.
