heating demand and limited heat loss.
What heating is required, is provided by efficient under
floor heating, keeping operating temperatures low and
maintaining a steady internal environment. This is
augmented in the winter by a wood burning stove.
The predominately East facing extension allows for
passive solar gains in the winter with the sun warming
the space in the morning. Conversely the orientation
of the building and the position of the brick chimney
provides shading on warm summer afternoons.
Full-height double glazing on all three sides of the
plan make the most of natural light limiting the need
for artificial lighting. Low energy LED lights are used
throughout, keeping energy demand low.
In all aspects, the extension was designed to be as
low-maintenance as possible, which adds to the
sustainability of the project: the exterior surfaces
consist of bronze standing seam for the roof, brick for
the walls, and highly insulated double-glazed window
units - none of which require any maintenance or
treatment.
Site waste was limited wherever possible; reused
or recycled, and remaining waste disposed of
responsibly. Materials were selected for their
renewable qualities and low maintenance
requirements.
