Solar Leaf 1

Leaf1_1

About This Project

Leaf 1 is the smallest solar passive dwelling at 47 square metres gross internal area. This is just large enough for a double bedroom, shower room, Kitchenette/Dining and a small Lounge. So it is suitable for two people, albeit being rather compact. The space standards of a caravan were what we were thinking of with this design.

As can be seen from the plans (which include the original layout sketch) the leaf shape cannot at this small scale contain all of the functions required, so it has been extended with a rear-facing rectangular section to contain the bedroom and shower room.

This design is solar passive, with the following features of the type:

  • Has a glazed solar collecting wall facing the sun.
  • Has open-planned living areas so that solar heated air is shared between them naturally.
  • Has solar shading of high summer sun (the extended roof overhang to the South).
  • Has superinsulation.
  • Has high thermal mass elements inside to hold heat in winter, and act to cool in summer.
  • Has opening windows at opposite sides of the structure to promote cross ventilation.

The materials are – in common with the other Solarity solar passive designs – masonry internal wall leaf with external insulation inside a rainscreen cladding, a hempcrete floor, a warm roof of plywood and timber with a glassfibre weathering surface.

It is envisaged that the top section of the roof of this design would have solar PV cells fibreglassed into it.
