    HEQ APPROACH
    TIMBER
  • Architecture Maison 14
    AN INDIVIDUAL SHOW HOUSE THAT INTEGRATES FOURTEEN TARGETS OF THE HIGH ENVIRONMENTAL QUALITY APPROACH










    TARGET 1
    The harmonious blending of the buildings with their immediate environment


    A bioclimatic greenhouse on the side of the Denfert-Rochereau Square, in the North-East of the site.


    On the side facing the square, the fifth floor (with terrace) forms an acoustic screen against the noises of urban traffic.


    The lower levels (first floor) found at the back of the plot allow the centre of the islet to breathe.


    Vegetation and greenery is omnipresent in the plot.

    - In the greenhouse, a hydroponic culture allows for water and energy saving, and rapid development of plants.

    - The wall at the back of the plot is covered by a net woven with hemp and coconut.

  • Architecture Maison 14











    TARGET 2
    integrated choice of construction processes


    Wood
    Skeleton of the structure, façade cover, posts in glue-laminated timber, wall and floor in Kerto panels. Insulation in excelsior.


    Concrete
    Foundations and the walls of the basement.


    Glass
    The windows of the building are made up of two panes of low emissivity glass with a clear panel of glass in the centre. The panes are separated by two argon blades, which is more insulating than air.


    A weathering-steel staircase

    Self- patinated steel by false surface corrosion.


    The finishing of the floors is in stone in the basement and ground floor and in wood on the following floors, as the two materials are the best adapted for heated flooring.

  • Architecture Maison 14
    TARGET 3 – Low-pollution building


    The construction allows for a prefabrication of the components in a workshop, and thus a rapid assembly of the structure, limiting the noise pollution of the building site.
    - the waste of the site is limited
    - The length of time that the building site operational is shorter

    The humid phase of the building site is limited to the construction of the concrete basement. During this phase, the use of water and the disposal of liquids are monitored.

    The techniques chosen allow us to limit pollution (both noise and dirt) that could affect the neighbourhood.

    The businesses involved are asked to used quiet machinery, and where possible, electric motors, which are less noisy than diesel motors.

    Access to the building site is adapted to avoid disruption to the life, activities and security of the residents. Traffic flow of the road is taken into account and delivery hours are fixed to periods where there is less traffic.

    The businesses sign the charter of the ‘building site of low pollution levels’.

    TARGET 4 – energy management

    Achieved by the creation of a well-insulated waterproof exterior. The objective: to reach an annual ARB of ≤50kWh/m². To be qualifiable for the 2005 High energy performance and the Low Energy Building label.

    This target also involves ensuring a dry temperature in winter of 19°C, and to keep the building cool in summer without producing cold air.

    Installation of photovoltaic sensors on the roof of the greenhouse, and solar detectors.

    Recapturing energy from the air extracted from the greenhouse and from the home by a double flux system with a heat exchanger and very high-output ventilation motors.

    De-humidification of the swimming pool: maintaining an accurate hygrometry by using a high-performance system of dehumidification. This is achieved by using a heat pump and reheating the pool water by collecting water in the condenser.


    Heating - The water heat pump/ water is on three vertical geothermic sensors and uses underground heat from near to the basement as far as 100 meters deep without moving the water from sheets or aquifiers.
    This provides heat for the heated floors and the boiler.

    Water Heating System - Produced by solar-thermal installation in vacuum tubes. The redundant energy is used to reheat the swimming pool.

    Ventilation - double-flux system with a very high output water collector coupled with the ventilation of the greenhouse.

    Comfort in summer - refreshment achieved by the use of geothermic sensors and cool flooring.
  • Electricity production
    Photovoltaic detectors transform solar energy into electricity. The module resembles a glass panel which filters diffused light through small gaps between the active surfaces. These panels are implanted as glass roofing over an area of 17m².

    TARGET 5 – water management

    To take into account:
    the management of the drinking water pipe network / Decontamination of used water / the establishment of a tank for collecting rain water / Water-treating systems to prevent legionellosis

    TARGET 6 – management of waste
    Local recycling sorting takes place in the basement. The use of water and liquid disposal is monitored.

    TARGET 7 – Upkeep and maintenance

    Greenhouse: self-cleaning windows
    The use of Bioclean from Saint Gobain on the exterior pane of the triple glazing stops the formation of condensation on the outside and preserves clear visibility regardless of the weather.
    There is a possibility of a nacelle and metallic duckboards on the side of the courtyard.
    Waxed parquet floor: use of cleaning products that respect the environment.

    TARGET 8 – Hygrothermal comfort
    The basin of the greenhouse regulates the hygrometry. The plants are chosen according to their ability to regulate the hygrometry of the greenhouse.
    Double flux ventilation
    The volume of air extracted may be regulated according to the humidity of the air thanks to hygrometric sensors. The double flux POWER STATION is equipped with filters that block polluting particles.

    Natural Ventilation
    Natural over-night back-up ventilation Mechanical control of the ventilation is linked to the opening of the fanlights.

    Triple Glazing
    Homogeneity of thermal insulation between the opaque glass wall/ suppression of the cold space close to the glass wall/ thermal insulation five times superior to that of double glazing.

    TARGET 9 – acoustic comfort

    The greenhouse forms an acoustic barrier against noise pollution caused by heavy traffic.
    The wood and excelsior provide an excellent phonic insulation.

    TARGET 10 – Visual comfort

    A play on light and transparency.
    The Climatop triple glazing has a high level of light transmission.
    The building also has an exceptional view over the Place Denfert-Rocherau
    Vegetated side-wall in the courtyard.

    TARGET 11 – Olfactory comfort

    High-performance ventilation
    Air filtration performed by plants
    Architecture Maison 14
  • Architecture Maison 14
    TARGET 12 – Sanitary conditions

    Creation of inside atmospheres
    Natural ventilation/ plants
    Facilitating cleaning and waste disposal
    self-cleaning triple glazing
    Local selective rubbish sorting
    Lift


    TARGET 13 – Air quality

    The living space and greenhouse are ventilated by a double-flux ventilation system with a high-output recuperator: controlling the hygrometry/ hygienic double-flux/ natural ventilation.

    The efficacy of the heating is improved by a double-flux system that humidifies using recycled air.

    The circulation of air is carried out by a double-flux power station of fresh air.

    Natural night ventilation cooling.

    The new air from the double-flux, hygienic air-treatment power station is taken from a window-well from the side of the garden.

    The double-flux system is equipped with a G4 filter, and the ventilation motors are high-output.

    The contaminated air is extracted from the humid rooms. The plants, such as rubber plants, ivy, spider plant, dracaena, schefflera plant, spathiphyllum, ficus, benjamina… all contribute to cleaning-up the surrounding air by absorbing the volatile organic compounds found within it .



    TARGET 14 – Water Quality

    A rain water-collection tank, and a physical separation of the entry of the rainwater and the town water network.
