The Larch House
With more than
half of its south wall taken up by glazing the Larch House is
more of a classic Passive House than its next-door neighbour.
Not only that, it is the UK's first zero-carbon Passive House,
designed specifically for Ebbw Vale.
While the Larch House - named
after its Pembrokeshire larch cladding - shares Passivhaus
principles with houses designed in Europe, it adapts them for
the more temperate, but cloudy and misty Ebbw Vale climate.
Winter sunshine is in limited
supply here, but large, south facing, Passivhaus certified
windows capture every bit of winter solar warmth, the extra
glazing makes for a brighter, lighter living environment. view
The closed-panel timber frame has been designed using
draught-minimising details developed in Austria, but constructed
from mostly Welsh timber. How those timber frame panels fit
together and their joints sealed is crucial to draught-proofing
a Passive House. In tests, the Larch House proved to be one of
the UK's most draught-free detached dwellings. If you don't like
draughts - or energy bills - this is the house for you!
In fact, not only is The Larch
House is a certified Passivhaus, it is a zero-carbon Passivhaus - a
first for the UK. Photovoltaic panels mounted on the roof
collect solar energy and their contribution reduces the house's
overall carbon footprint to zero.
