Scotland The Roundhouse Findhorn

Passive Solar
The Roundhouse has twenty square metres Pilkington K argon filled double glazed glass integral to the upper floor design. This is orientated to the south for maximum collection of low winter sun between 11.00 am and 3.00 pm.

The external terrace balustrade is wire-strung to minimise obstruction of low winter sun, whilst high summer sun is restricted by an overhang whose dimensions were determined by solar profiling.

The solar collector and thermal mass store is the forty ton concrete inter-floor. Black ceramic tiles maximise solar collection and radiation.

These measures are sufficient to heat the house for nine months of the Scottish year.
