    A key project driver for the client is the reduction
    of energy consumption and reference will be made to Passivhaus
    practice. Although the full Passivhaus standard cannot be achieved in
    an older property of this kind, the scope of works will include
    upgrading of all windows, external insulation to side and rear walls,
    reduction of air leakage, introduction of energy efficient mechanical
    ventilation with heat recovery. The extension will be designed to
    achieve very good levels of thermal insulation and airtightness. The
    large southern facing windows will contribute to reduced energy use
    through passive solar gain.

  • You can retrofit any building to Passivhaus standards. There were a few players trying to do just that with huge outer envelopes ~10 years ago, but surprise surprise they didn't get much traction in the UK.

    If a key driver was reduction in energy consumption, why is there a wood stove and exhaust poking out the roof of it? Fail.
